PILC Cables Paper Insulated Lead Cables
Oil barrier heat shrink sleeves are applied to PILC cables to prevent the cable oil from dripping out and can be used to increase the cable insulation up to 33kV for joints and terminations. These oil barrier heat shrink tubes are made from high quality cross linked polyolefin material and are clear (transparent) – the heat shrink tubes can be supplied on continuous spools or pre-cut lengths.
Prior to jointing cables the paper insulated cables can be wiped down using cable cleaners to remove the oil residue and ensure clean jointing of cables.
Thorne & Derrick supply LV cable jointers with an extensive range of cable jointing kits (heat shrink, Cold Shrink, resin cast), cable jointing tools, underground cable protection and cable pulling equipment to enable the safe and reliable installation of low voltage cables 600/1000 volts.
Thorne & Derrick can recommend LV Jointer Training Courses for Jointers requiring Competency Certification to joint PILC cables covering :
• Identification Of LV Cable Types
• Single Phase Sub Service Transition Straight & Breech Joint
• Three Phase Sub Service Transition Straight & Breech Joint
• Single & Three Phase PILC Cutout
• Single & Three Phase PILC Pot End
• Three Phase & Single Phase PILC Service Joint
• Transition Breech & Straight Joint
