Raychem TFTI
Raychem TFTI is a high voltage cold shrink, cold-applied cable termination designed with an extended neck to cover the mechanical shearbolt cable lug connection. Additional anti-track heat shrink tubing has been applied onto the MV HV cable sheath jacket for the centre phases to achieve enhanced electrical insulation between copper wire shield and the medium/high voltage busbar – the cold shrink terminations provide safe cable connections for working in potentially explosive atmospheres such as MV HV substations where flammable gas could be present.
The cable conductors are terminated using either crimp (compression) or mechanical (shearbolt) high voltage cable lugs from manufacturers such as Cembre or Pfisterer SICON.

Providing Competency Training Courses For Cable Jointers LV
By Chris Dodds - Thorne & Derrick Sales & Marketing Manager
Pragmatic Consulting Ltd have been approved to deliver under EUSR – Competency Accord Unit 060 Live LV Cable Jointing Training Courses.
Pragmatic Consulting offer a range of courses that meets the needs of the Cable Jointing, Electrical and Utility Power Industry and are prepared to travel and provide cable jointer training events across the UK so that you are able to have training when it suits you.
Pragmatic Consulting approach each Cable Jointer Training Course in an individual manner to ensure candidates who pass through the door are trained to the highest standard whilst ensuring that they receive the support they require to help them progress and achieve.
Training: Live Cable jointing On Mains Cables
After successful completion of the Cable Jointers Training Course and assessment the candidate will then need to complete a period of supervised on job experience, before returning with his / her evidence portfolio and undertake a formal cable jointing skills and knowledge assessment – this will preserve trade integrity and protect employers against under-skilled labour causing reputational damage to the industry.
On successful completion of their portfolio, witness testimonies and further assessment each candidate will then be eligible to have their achieved competence modules registered on the Energy and Utility Skills Register (EUSR) for acceptance as a level of Competence by member Companies of the Industries Competency Accord scheme.
This is cable jointer training and assessment and not authorisation.
Power Unit 060 has been split this into 3 separate cable jointing courses:
LV1 Training Course
LV2 Training Course
LV3 Training Course
EUSR help employers to develop industry recognised schemes of learning and register individuals’ skills and competencies on their register.
The EUSR provide workshops to approve trainers for Passport Schemes such as Safety, Health & Environmental Awareness (SHEA) Water Hygiene and Cross Country Pipelines Health Safety & Environmental (CCPHSE).
This cable jointer training specification has been developed from the power network standard. The specification details the required skills, knowledge and behaviours to establish competence to carry out live jointing procedures on low voltage mains cables.
The specification details the requirements for TWO separate low voltage categories. Candidates will be assessed and receive registration for BOTH of the following categories:
The specification details the critical requirements of the activity to establish competence and does not preclude employers from adding to the skills and knowledge detailed by the specification in their own training programmes.
What does competence look like?
LVJ1 Course – The cable jointer will be able to confidently carry out a range of live low voltage electrical cable jointing procedures on underground cables in accordance with company procedures.
LVJ2 Course – The cable jointer will demonstrate a safety conscious approach to the control of hazards associated with the activity whilst working and communicating effectively with other team members to achieve tasks.
What do I need to take this module?
Candidates to be assessed as competent in this skill area should have completed the modules shown below or have evidence demonstrating an equivalent level of competence:

Centriforce Stokbord underground cable protection covers are manufactured from high impact, recycled polyethylene designed to withstand damage and protect medium/high voltage cables from plant and hand tools – the cable covers protect high voltage cables from damage caused by diggers and excavators inadvertently causing cable strikes when working around underground cables and utility services.
Both Tape Tile and Stokbord cable covers are used to protect LV-HV cables and cable ducts installed by the ‘open cut’ trench method – the cable protection products are intended, during any future excavation work, to give a clear visual warning of the presence of underground cable, cable joints or cable ducts. The cable identification is compliant with ENATS Standard 12-23 and meets the impact requirements of BS2484.
Pictured: High Voltage 11kV Cable Strike – an excavator has impacted onto a 11kV high voltage power cable penetrating the cable sheath and XLPE insulation to cause a power outage. Lack of planning on development projects increases the possibility of serious injuries to operatives and greatly increase cost to projects. On site cable records and use of cable fault locators should ensure worker safety and prevent accidental damage and strikes to high voltage cables.
Damage to underground cables can have serious repercussions such as damage to anyone working on or near the cables or a power blackout such as that experienced in Londonderry, December 2013.
LV Low Voltage | MV Medium Voltage | HV High Voltage Cable Protection
Centriforce Stokbord cable covers are suitable for underground high voltage cable protection (22kV, 33kV, 66kV, 132kV and up to 400kV). The 4 thickness variations of Stokbord covers are 6, 9, 12 and 18mm. This coupled with the fact that Stokbord is easy to fabricate ensures Centriforce Stokbords are the ideal product for protecting underground cables.
Stokbord Cable Cover Application
Centriforce Stokbord Cable Covers are fully jointed, laid overlapped and connected with plastic jointing pegs to provide safe high voltage underground cable protection.
Centriforce Stokbord cable covers feature a red background with yellow top tape containing visible warning “Caution Electric Cable Below” – Stokbord cable covers meet BS2482 impact requirements for underground cable cover protection.
Not only does this protect from any impact to the cables that would be made by excavation, it also shows exactly where cables are laid. The locating of cables is therefore simplified.
The features and benefits of Centriforce Stokbord makes the performance of the products far superior to steel and concrete cable covers / tiles /plates.
Installation Of Cable Trench Covers & Cable Protection Tiles
All cables and ducts laid into cable trench should be over-protected by a cable protection cover or tape depending upon the highest voltage cable to be protected within the cable duct – typically in the UK the following cable protection tapes and covers are used for LV, MV and HV cables.
Marker tile tapes or Stokbord covers are installed over the cable in the appropriate trench drawings – usually there is no requirement to install either above approved cable ducts installed using trenchless techniques (i.e. directional drill) but either may be installed if it is deemed that additional MV-HV cable protection is required.
When Tape Tile is used it should be cut cleanly and installed so that the medium/high voltage cable is fully covered along the whole length of the installed cable duct.

Underground Cable Protection
Thorne & Derrick International distribute the most extensive range of Cable Pulling & Cable Laying Equipment to enable the installation of low, medium and high voltage power cables into underground trench or duct – products also supplied for fibre optic blowing, subsea trenching, offshore umbilical installations and pulling armoured cables onto cable tray.
