FiloSlim Cable Sheath Repair System

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.

EPR, XLPE, PVC, PILC LV, MV & HV cable sheaths

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.

No heat source > total mechanical protection, suitable for low, medium and high voltage cables.

Questions & Answers

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)

Flexible Resin

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.
