Have a damaged cable sheath or jacket?
Look no further – Filoform have innovated and made repairing a cable sheath simpler, stronger and hassle free.
Whilst repairing damage to the outer sheath of a cable may seem like a formality, it is often subject to unforeseen conditions. Particularly if the cable is to be buried or subject to severe environmental elements.
Recognising these situations – FiloSlim Cable Sheath Repair Kit can repair them quick & easily with NO heat or special tools.
Repair Damaged Cable Sheaths
The FiloSlim Cable Repair kit has been designed to accommodate all types of cable sheath, and to withstand the rigors of many applications.
The unique Polyurethane Resin has been manufactured to offer protection in the harshest of conditions. Subsea, exposed to UV, wound onto cable drums and subject to attack by hydrocarbons within the petrochemical industry.
The FiloSlim Repair Kit is designed to offer a multi-functional, single solution, suitable to all markets. Onshore, Offshore, Hazardous Area, Direct Buried, Subsea: all remedied by a single product.

The totally enclosed mixing and pouring of the resin via the nozzle and non return valve.
Both the valve and outer tape wrap is removed easily at the end of the installation – offers a secure and safe method of work; even in the harshest of environments. From a pitching deck to a frozen landscape, Filoslim is quick, safe and easy to apply.
No specialist tools. NO HEAT source or naked flame.
One kit to suit all cable diameters up to 170mm, and the ability to offer bespoke solutions beyond that. Sheath repair made simple.
Questions & AnswersÂ
1, Can the blue injection valve be removed?
Yes, the tape and valve can be de-laminted after 1 hour of dispensing the resin.
2, Is the resin flexible?
Yes, the resin will flex but does require a little force.(Example below shows a 95sqmm 4 core un-armoured cable)
3, Will the FiloSlim cable sheath system repair work if the damage is through to the conductor?
If we are talking about an LV cable, unarmoured, and with no damage to the conductor; we would say its fine. The conductor insulation being intact has retained the original integrity of the primary insulation within the cable;
However, if the insulation around the conductor has been damaged, we would propose stripping back a section of the cable and exposing the damaged area but not cutting the cable.
Over-taping this with self-amalgamating tape will restore the original integrity, and then the kit can be used from there.

Thorne & Derrick | Supplying 3M Scotch Tapes to the Electrical Industry
Today Levingston George, Lead Specialist Electrical Engineer at AM/NS Calvert in Alabama shares some cable jointing tips using 3M Scotch Tapes.
Levingston George has over 40 years of experience within the construction, maintenance and utilities industries – a Certified High Voltage Cable Splicer/Lineman and industrial electrician having worked in more than 26 countries on multi-million dollar projects. 
Levingston kindly shares some “tips n tricks” using 3M Scotch Electrical Tapes in the medium voltage power industry.
“In cable splicing and jointing all cable insulation needs to be sanded, be it XLPE or EPR insulation.”
“A good rule of thumb is “cleanliness is the rule and the cleaner the cable joint the better it will operate and test.”
“Many jointers do not understand the requirement of the semi-con screen being square and perfectly cut. SRM (stress relief material) in many of the splicing kits is often disregarded – and then the cable fails. I have also noted that many cable jointers use indenter crimp tools and they forget to fill the voids left by the crimping tool.”
“Then the butt splice has air voids and this leads to cable failure. If using an indenter type crimp tool always fill the voids created by the tool with mastic. I have found Scotch 2229 Mastic Tape to be effective for the application. Also 600 volt butt splices should never be used on medium voltage cable –  the cable should be chamfered at the butt splice and the butt splice itself (MV and HV butt splices) are tapered for a reason.

“I also use Scotch 13 Semi Con Tape to go over the butt splice to place the strand shield back on to the medium voltage cable. This prevents air voids at the conductor entering the butt splice and returns the cable to its configuration prior to making the cable splice. PILC is still around here in the USA and there are few splicers who are actually trained to repair it professionally,” informs Levingston.

Access Chambers for LV HV Power & Trackside Rail Cables
LV HV Power & Trackside Rail Cables
HS2 Case Study
The vast scope of redevelopment by Cubis to transform London Euston Station into the first modern, intercity transport hub for high-speed rail services is well underway. Euston Station is one of 4 stations that will be transformed ahead of the new High Speed 2 (HS2) rail line connecting London to the Midlands, the north of England and Scotland.
Network Rail and Skanska, on behalf of HS2 are delivering enabling works at the station and surrounding area, with the groundworks being subcontracted to Kilnbridge. This will see the eventual construction of a 25,260m² terminus, new high-speed platforms and improvements to the surrounding open public areas.
To enable the new Euston station development to take place, works have begun on constructing a new electrical substation that will assist in powering the station and its facilities.
Cubis Modular Access Chamber Range STAKKAbox
The new substation, located just off the main London Euston line at Barnby, has been erected to distribute both HV and LV power cables into the substation and onward to the track and station. The substation, like many new buildings in London, is located within a restricted area with limited access, storage and mobility.
The project had a requirement for cable draw pits with easy accessibility for new power cables and in the future-proofing of the development for any new HS2 station and track cabling requirements. However, site conditions would not allow for a traditional concrete access chamber construction due weight and access restrictions. Cubis were approached to provide advice on our innovative, lightweight and modular access chamber range, STAKKAbox™.
ULTIMA Access Chamber
The team at Skanska worked with the Cubis Technical team to design and specify STAKKAbox™Â ULTIMA Connect due to its lightweight and flexible onsite capabilities with the capacity to be installed manually without the need for skilled wet trades.
The individual 150mm deep sections of twin-wall GRP that make up the ULTIMA Connect chamber system provided a lightweight, modular solution with components falling under 25kg making them suitable for a single person lift under manual handling regulations.
With the added flexibility of being delivered to site with pre-drilled duct entries and the need only to reassemble the chamber components, the overall installation was significantly faster in comparison to conventional alternatives.
STAKKAbox™ ULTIMA Connect was designed and supplied to seamlessly integrate with Cubis’ B125 composite AX-S™Â recessed access covers, providing a complete site chamber access and cover solution, while offering an improved aesthetic finish to the open public space, situated alongside the new substation. This integrated system offered a complete solution for the customer, reducing both time, health and safety risks and resulting in a significant overall cost saving.
Access Chamber Step By Step Installation Guide
STAKKAbox™ chambers are significantly faster to install than conventional alternatives, with complete installations typically taking under one hour. This results in reduced costs for the installer and significant time saving. No specialist equipment or plant is required in order to install an access chamber and there is no need for specialist box builders. With flexible installation, Cubis access chambers can be adapted to suit on-site conditions with standard tools to build over existing networks.

Roxtec Sealing Systems: Electromagnetic Shielding
Electromagnetic Shielding
Roxtec cable seals are used in cable vaults, duct banks, electrical substations, trenches and M&E building services protecting low, medium and high voltage power systems against numerous external risk factors including fire, gas, water, cables, pressure, electrical, particles and blast.
Why do you have to protect critical LV MV HV infrastructure equipment against EMI, IEMI, EMP and HEMP? How can you both seal and secure the electromagnetic shield? There are many questions regarding electromagnetic threats.
Roxtec are happy to be able to provide answers – and cable transit solutions.
Their skills and expertise enable the correct solution to be chosen that has electromagnetic shielding alongside fire, gas and water ingress certification.
EMC refers to good electromagnetic compatibility.
Disturbances can be attributed to electronics like computers and mobile phones.as well as war or acts of terror. They can majorly affect electrical equipment and critical power supply to hospitals, banks and server halls, and a blackout can be very expensive.
The Roxtec ES sealing system provides an effective protection when used in shielded environments. It diverts conducted disturbances, shields against radiated disturbances and provides a mechanical and environmental protection against fire, gas, water, dust, dirt and rodents.
Roxtec can help you protect equipment against the effects of HEMP, a high-altitude electromagnetic pulse caused by a nuclear weapon far above the surface of the earth. HEMP causes chaos through electromagnetic pulses. It makes transformers explode and can cause breakdown of the entire power grid.
At the Roxtec test lab, we use shielded rooms, antennas, transmitters and receivers to verify the ability of our seals regarding attenuation of radiated interferences. The cable seals have undergone numerous shielding attenuation and transfer impedance tests.
