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 95mm 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.
