How To Remove The Aluminium Sheath From Consac Cable
- Mark the aluminium sheath at the cable joint centre and make an additional two extra marks at 60 degrees to form an arrow – this arrow MUST point to the cable jointer
- Select the correct cutting wheel for the Consac sheath stripping tool according to the cable cross sectional area. The 45 thousands of an inch cutter is used for 70mm to 120mm cable, the 70 thousands of an inch cutter is used for 150 to 240mm cable
- Set the angle of the Consac sheath cutting tool to 60 degrees, using the front control wheel and scale
- Using the rear pressure control wheel, open then close the tool onto the first of the 60 degrees marks. Apply the light pressure then rotate the tool outward along the cable until it butts up to the PVC sheath edge, this should occur at tool bottom dead centre
- Repeat this operation, moving the cable jointing tool forward and backward along the cable, gradually increasing the pressure using the rear wheel. Continue this process until scuff marks from the shoulders of the cutting wheel appear along the edges of the cut, then stop
- Remove the cable cutting tool and re-set the cutter angle to 60 degrees on the opposite hand. Re-fit the tool and repeat operations 4 & 5. Remove the tool on completion
- At the point where the two tool cuts join, use the edge of a six inch half round file to deepen the cut until the underlying papers begin to appear. The flat side of the file must point towards the inside of the arrow
- Using a hammer and pliers lift the point of the arrow – wearing insulating gloves unpeel the aluminium sheath from the cable until the ends of the cut are reached. The sheath should now appear as shown in the illustration pointing away from the cable jointer
- Fit PVC binders at the points where the underlying papers are to be terminated
- Bear the cut part of the sheath flat with a pair of wooden beaters
- Holes can be punched in the aluminium sheath where required using a special purpose hole punching tool
Note: Using approved cable cleaning wipes ensure that the prepared Consac cables are cleaned thoroughly and all dirt, debris or contaminants are removed.

Triplex Cleats – Selection Guide for Cleating 11kV BS7870 Part 4.10 Cables
July 25th, 2018
Distributors for Ellis Patents Cable Cleats
- uploaded by Chis Dodds – Thorne & Derrick Sales & Marketing Manager
The following post is provided to enable the selection of cable cleats to suit a standard UK DNO utility cable for medium/high voltage power systems – this type of MV HV cable commonly referred to as “Triplex” cable has increasingly replaced conventional BS6622 11kV 3 core XLPE insulated cable.
Triplex cable consists of 3 x single cores in a “twisted” spiral formation – this non linear cable orientation must be recreated into a circular formation using Triplex cable surrounds.
It is essential to effectively cable cleat Triplex cables to containment to ensure safe and reliable cable restraint in the event of a short-circuit situation – to simplify the cable cleat selection process it is a basic requirement to consider the calculated short-circuit fault current rating, installation environment and overall outside diameter of the 3 x single core cables when combined in Triplex formation.
The short circuit calculation would normally be the responsibility of the Electrical Design Engineer and can be calculated using a formula as recommended by IEC61914 the international standard which specifies requirements and tests for cable cleats and intermediate restraints used for securing cable in electrical installations.

Correctly Sealed Cable Ducts Will Protect From Ingress Into Potable Drinking Water
July 16th, 2018
-
uploaded by Chris Dodds - Thorne & Derrick Sales & Marketing Manager
The following information is provided courtesy of Severn Trent Water as part of their series of Lessons Learn Bulletins which highlight the potential use or adoption of products to ensure cleaner, safer and more reliable distribution of water supply – specifically this short update is focussed on duct sealing to prevent pollution of potable drinking water.
Brief Description
The Whitacre / Warwickshire team identified a shortfall in the way cable ducts are sealed following installation of new and the maintenance of existing assets.
This was identified as part of coliform investigations where there is a potential for water ingress into injection chambers, reservoirs and back wash tanks. Lack of correct duct sealing in this instance resulted in water entering a level probe chamber with the potential to pollute potable drinking water.
Sealing Cable Ducts
Several options to securely seal cable ducts have been investigated with support from Water R&D. As a result of findings Asset Creation updated the STW design manual for E&M Plant Electrical Design (DM0106-03) and issued a technical bulletin informing key departments, ensuring that the new minimum standard is adhered to.
Two duct sealing kits were used and approved by PH&S, both provided similar results.
PLEASE NOTE: These kits are not DWI Reg 31 approved and must not be used where direct contact with potable water occurs. Any proprietary seal kit used must be of the type listed in the Water Industry Mechanical & Electrical Specification 3.02 (SPC 0302-W302).
Lessons Learnt
Share at your Comm Cells with your operational and maintenance teams.
• During routine inspections check for any cable ducts which could possibly allow ingress into reservoirs or injection chambers which could lead to a water quality failure?
• Contact either of the above for any assistance for procuring and advice on installing the sealing kits.
• Track any next steps via your Comm Cell, raise WQ U/C and sign off when complete.

Lightning Protection Earthing Systems – Type A,B & Foundation Earth Electrodes
July 10th, 2018
-
uploaded by - Chris Dodds (Sales & Marketing Manager Thorne & Derrick)
The following information has been provided courtesy of AN Wallis, leading UK manufacturers of Earthing & Lightning Protection Systems.
In general the Lightning Protection System (LPS) system should:
- Be an integrated system for lightning protection, power systems and telecoms systems
- Have a low overall resistance of 10 ohm’s or less
- Have an even spread of readings across all the individual earth electrode terminations to ensure as far as possible the current is evenly distributed
- Have a high resistance to corrosion
Lightning protection and earthing equipment is usually made up of earth rods either copperbonded, solid copper or stainless steel (figure 25) – also forming the earthing system are copper earth plates (figure 26), copper lattice earth mats (figure 27) or 25 x 3mm copper earth tapes.
Driven earth rods manufactured from solid copper and bonded with copper are available from stock – contact Thorne & Derrick
There are three types of LPS Earthing systems types A, B and Foundation Earth Electrodes
Type A – The conventional LPS Earthing system using
vertical or horizontal electrodes such as
copperbond Earth rods or copper tape
Type B – The ring electrode sited around the periphery of the structure
Foundation Earth Electrodes
The foundation electrode system installing the conductors in the concrete foundations of the structure.
Type A Earthing Arrangement
This is the conventional type of LPS Earthing System where earthing rods are used to form the earth electrode and usually each down conductor, such as copper earthing tapes, are connected to an earth rod.
The type A earth termination arrangement is suitable for low structures (below 20 metres in height) or an LPS with rods or stretched wires. For an isolated LPS the British Standard BS EN 62305 recommends a type B earthing arrangement where the structure is housing extensive electronic systems.
The type A arrangement uses vertical or horizontal earth electrodes. Practically it uses both connected to each down conductor, installed outside the structure (below the foundation) to be protected and housed in a plastic or concrete pit for ease of inspection (figure 30).
Lightning Protection – Copper Earthing Equipment
The minimum number of electrodes is 2.5 metres, regardless of the perimeter of the structure/class of LPS.
The minimum length of each earth electrode at the base of each down-conductor is specified in BS EN 62305 and the table below.
Minimum length l¹ of each earth electrode according to class of LPS
It is 11 for horizontal electrodes – usually copper tapes.
Or
0.511 for vertical copperbonded rods or solid copper rods. Or
>11 in the case of a lattice mat measuring the total length of the conductor in the earth mat.
Or
If copper plates are to be used the surface area of the plate should be at least equal to either.
The surface area of the length of earthing conductor that would need to be used to satisfy the requirement for a vertical electrode 0.511.
Or
The surface area of the length of earthing conductor that would need to be used to satisfy the requirement for a lattice mat electrode 11.
Or
If using vertical and horizontal electrodes, the individual earthing electrode lengths should follow the 0.511 and 11 principle respectively.
Type A earth electrodes should be installed so that the top of the earth rod is 0.5 m below the surface, this distance is to reduce the effects of step potential at ground level.
The earth rod should be housed in an inspection pit, commonly concrete or plastic for ease of inspection and registering the location during and after installation figure 30.
Full range of copper earth tapes available from stock in range of widths and thicknesses.
Type B Earthing Arrangement
The type B Earthing arrangement is most suitable for:
- Structures built on rocky ground
- Structures housing sensitive electronics/equipment
- Large structures
The type B earthing is recommended as either a ring conductor outside the perimeter of the structure which it’s recommended should be in contact with the soil for at least 80% of its total length.
The alternative is to use a foundation earth electrode which can be in a mesh form.
It is recommended that the type B earthing network whichever method is chosen should be integrated as a meshed network buried to a minimum depth of 5 rats.
The reinforced concrete floor slab can be used around the structure.
If the required resistance cannot be achieved by this method the vertical or radial earthing electrodes can be added to the network.
For ease of testing after installation an inspection pit with an earth bar should be installed where the legs of the ring and conductor routing onto the ring from the each test clamps join (figure 31).
Any internal down conductors should be connected to the internal foundation using a test clamp for ease of maintenance.
Foundation Earth Electrodes
Once all the services are connected its unlikely the installer will be able to measure the earthing resistance of the foundation earth in isolation.
The use of the foundation as an earth electrode is allowable only where the reinforcement network is below any insulating or waterproof membrane.
Where a foundation is used as an earth-termination the reinforcing bars must be clamped or welded together to ensure electrical continuity.
Alternatively an additional meshed network of conductors can be installed to ensure continuity. The additional network should be connected to the reinforcing bars by clamps or welded joints every 20 m throughout the system.
The earthing system whether using reinforcing bars or additional conductors or a combination of both must be connected to every down conductor and internal steelwork.
Internal Lightning Protection System
The internal LPS is important to fully complete the installation to fulfil the requirements of BS EN 62305.
The main reason for installing an internal LPS is to avoid any dangerous sparking within the building.
The sparking is caused by current flow and the difference in potential between internal conductive components such as steelwork and the external LPS on the outside of the building or from the use of the internal steelwork as part of the LPS.
The earthing system whether using reinforcing bars or additional conductors or a combination of both must be connected to every down conductor and internal steelwork.

BS EN 62305 – Earthing & Lightning Protection System Design
July 10th, 2018
-
uploaded by - Chris Dodds (Sales & Marketing Manager Thorne & Derrick)
Design of Lightning Protection System
The following information has been provided courtesy of AN Wallis, leading UK manufacturers of Earthing & Lightning Protection Systems.
The LPS (Lightning Protection System) is required to:
- Intercept the lightning strike (the air termination network)
- Conduct the lightning strike safely to ground (using down conductors, such as copper earth tapes)
- Disperse the strike safely into the earth (earthing)
- Whilst the structural protection is there to conduct a strike safely to earth this is normally combined with internal protection to prevent sparking within the structure ensuring all metallic services are at equipotential (bonding)
The designer of the LPS should ensure that:
- The safest path to earth is the LPS
- The risk of sparking whilst the strike is conducted safely to earth is minimised (separation distance/s)
- The risk of voltage differential whilst the strike is being dissipated in the ground safely is minimised (step & touch potentials)
The designer of the LPS has to gather all the relevant information to ensure the earthing system design is as safe as possible within any economic restraints:
- A designer may find it impractical to fully install the desired LPS
- A designer may not be able to justify the cost of providing the desired LPS
- A designer may consider using the metal roof or reinforcing bars within a building as the safest and most economic design
- A designer may consider extra bonding and surge protection devices are required to protect the internal space, especially if the space houses sensitive electronic equipment
- A designer may consider a building of such a high risk that additional measures are taken to ensure safety, possibly a flour factory or a building with a combustible roof, in these cases the LPS system may have to stand off the building
Contact Thorne & Derrick for largest UK stocks of copper earth tapes.
Criteria For The Protection Of Structures
The level of protection/Lightning Protection Level (LPL) applied to the structure is identified by the risk assessment.
Lightning Protection System (LPS) Level
- LPL I requires a Class I
- LPS LPL II requires a Class II
- LPS LPL III requires a Class III
- LPS LPL IV requires a Class IV LPS
Design of The LPSÂ General Considerations
To help the earthing system designer, the threat of lightning to a structure or building can be defined in lightning protection zones requiring protection and the type of lightning strike likely to enter the building shown in Figure 2.
S1 – Strike directly to the structure
S2 – Strike on the ground near the structure
S3 – Strike to a service connected to the structure
S4 – Strike on the ground near a service connected to the structure
LPZ1 – The protected zone inside the building, the zone where current is limited by current sharing and SPD’s at the boundary (less the separation distance)
LPZ Oa – At risk from the full lightning strike and the full lightning electromagnetic field
LPZ Ob – Not at risk from a direct lightning strike considering the protected area through the rolling sphere but at risk from the full lightning electromagnetic impulse. (LEMP)
LPZ 2 – Protected zone with further dampened magnetic field
The LPS designer should ensure everything to be protected falls inside the LPZ Ob range in figure 2.
- The bonding measures employed need consideration at the design stage
- The earthing design should consider fully the step and touch potential risks
- The requirements for Surge Protection Devices (SPDs) on incoming mains and conductive services should be considered in accordance with the risk assessment carried out for the structure LPS requirements
- Where combustible wooden type materials are present a distance of 0.15 m should be maintained between the LPS conductors and the roof, for any other combustible surfaces a distance not less than 0.10 m is required
- Some structures will have reinforced sections with expansion joints, if the designer of the LPS considers electronic equipment within the building is at risk then bonding conductors should be provided across the joints to provide low-impedance potential equalization. The separation distance between the bonds should not be more than half the distance between the down conductors
- Natural components within/part of the structure such as the rebars can be made use of provided they will always remain an integral part of the structure conforming to the requirements below
Manufacturer by high conductivity and purity copper the range of earth tapes provide effective protection to buildings and substations
Using natural conductors as part of the LPS
The building’s natural components, metal roof, rebar, steelwork etc can be considered as part of the LPS provided they meet the minimum criteria shown in Table 1.
| Material for LPS levelI to IV | Prevents puncture, hot spots or ignition. minimum thickness (mm) (ta) requirement | Â Only for metal sheets where preventing puncture, hot spots or ignition is not important. minimum thickness (mm) requirement (tb) |
| Lead | 2.00 | |
| Stainless Steel | 4 | 0.50 |
| Titanium | 4 | 0.50 |
| Copper | 5 | 0.50 |
| Aluminium | 7 | 0.65 |
| Zinc | 0.70 |
The reinforcing bars within the concrete structure can be used as a natural component of the LPS provided they are electrically continuous by either welding or clamping the joints.
The re-bars are considered as electrically continuous provided that the major part of interconnections of vertical and horizontal bars are welded or otherwise securely connected by clamps conforming to BS EN 50164 standards.
The connecting rebar must overlap and be clamped using rebar clamps or welded to a minimum of 20 times the diameter of the rebar as shown in figure 3. (Welding to be done on either side of the rebars.)
Example of a rebar joined by clamps
To test the continuity of the reinforcing bars the resistance between the re-bar connection to the air termination network and the rebar connection to the earthing network should be measured, the resistance should not exceed 0.252, otherwise proprietary down conductors will be required.
In order to provide a connection to the rebar from outside the concrete a cast-in earth plate can be used as shown in figure 4, the earth point sits in the wall (or within an enclosure) providing a connection to the re-bar with a welded copper tail attached to the earth point and to the re-bar with propriety clamps.
Earth point sits in the wall providing a connection to the rebar
The designer of the structural LPS has 4 main criteria to consider:
- The roof termination system
- The down conductor configuration
- The Earth Termination network including equipotentialization and the risk of step and touch potential (equipotentialization on its own is not effective in reducing the risk against touch voltages)
- Bonding (creating a euipotential zone across all zones, Oa, Ob, Z1, Z2)
The diameter of the sphere depends on the class of LPS selected/determined.
| Class LPS | Sphere Radius |
| I | 20 |
| II | 30 |
| III | 45 |
| IV | 60 |
Complete range of earth bars with connection options and number of cable termination ways to provide effective common isolation point.
Methods Of Designing The Air Termination Network
1 – The rolling sphere
2 – The protective angle design
3 – The mesh design
The Rolling Sphere Method
This method simply rolls a sphere around the building to be protected, wherever the sphere touches the building dictates where the protection measure is to be applied, where the sphere does not touch the building, this is accepted as a protected area, this method can be used to design the LPS on complex structures or where the LPS has to be isolated.
The rolling sphere method is especially relevant on complex structures with many different levels, this method easily identifies the protected space and where protection measures should be applied to the structure.
Examples of the air termination system using the rolling sphere technique
Designing The Lightning Protection System (LPS)
The Protective angle design
The Protective Angle method in figure 10 is only used on simple structures or for small sections of larger structures.
The Protective Angle design method cannot be used where the part of the structure/service to be protected is higher than the radius of the rolling sphere corresponding to the class of LPS.
The level of LPS dictates the angle of protection depending on the reference height, see figure 9.
This method of earthing system design is an alternative method based on the rolling sphere and is not offered to give a wider range of protection than the rolling sphere.
In figure 9 the height limits for designers are clear and correspond to the radius of the rolling sphere.
Protective Angle Design
The Mesh design
The most commonly used method, is usually employed where the structure is simple, a square or rectangular building or typical house or block of apartments with a sloping roof, the mesh method is for protection in zone OA.
The mesh design protects the whole area if conductors are positioned on the edge of the roof where the slope of the roof exceeds 1:10.
Protective angle design to protect free standing equipment on the roof of a building
On structures up to 60 metres in height, only consider applying an air termination system to the roof and provide protection to points, corners and edges of the structure. No lateral air termination is required regardless of the class of LPS.
On structures higher than 60 metres lateral air termination systems should be applied to the top 20% of the structure relevant to its class of LPS (or at least conforming to class IV LPS).
The mesh of earth conductors are installed on the roof, the earth conductor must be at the edge of the area to be protected and for metal items such as air conditioning units that protrude above the conductor, the protective angle design should be applied for protection.
The size of earth mesh required is defined by the level of LPS determined/selected
| LPS Class | Mesh Size (M) |
| I | 5 x 5 |
| II | 10 x 10 |
| III | 15 x 15 |
| IV | 20 x 20 |
