Repairing Damaged Cables & Sheaths

Thorne & Derrick distribute Cable Repair Products for low, medium and high voltage power cables, this includes heat shrink wraparound repair kits and flexible repair and jointing kits utilising insulating resins.

During cable installation it is usual to ensure the cable duct, trench or shaft are void of foreign bodies or sharp edges which result in tear damage inflicted onto the cable sheath – rock, stone, hardcore and hard fill can all damage exposed cables during underground cable installations. All underground electrical services and cables are usually protected with Stokbord 33kV and Tape Tile 11kV type cable covers depending on cable voltage nevertheless cable damage remains common at LV MV HV.

Mechanical damage is often incurred to the cable by exceeding the maximum bend radius or cable “snag and drag” on the bottom of trenches causing sheath damage through contact with stones or aggregate – cable repair is most commonly necessitated in response to damage caused during excavation works.

Cable repair products are suitable for repairing damaged cable sheath jackets on XLPE, PILC and EPR cables where nicks or tears have compromised the integrity of new cable installations during the pulling process or where insulation must be improved on ageing electrical cable circuits.

Cable repair kits for MV-HV cables including 11kV, 33kV and 66kV polymeric type power cables – cold applied repair tapes are available where “hot-working” precludes use of traditional heat shrink products.

Whether cable pulling installations are manual or motorised inevitable damage is incurred to trenched cables due to the presence of sharp objects – accidental mechanical cable damage is also common during heavy armoured cable pulls at low/medium/high voltage when power cables must be secured to cable containment often overhead and subject to angled routing and bends.
