11kV Cable Joints Single Core PILC Heat Shrink Straight Joint Kits

Cable Joints 11kV | Single Core | PILC | Heat Shrink
Thorne & Derrick | Distributed from Stock | Approved Supplier | UK & Export Sales
HV cable joints are suitable for medium/high voltage (MV-HV) 11kV single core paper insulated cables (PILC) – cable joints use heat shrink tubes and suit 11kV cables with 50sqmm to 630sqmm single core conductors (copper and aluminium).
11kV Cable Joints
11kV heat shrink cable joints suit unarmoured and armoured PILC single core cables – this includes high voltage industrial power cables used for primary connections to HV switchgear, transformers or pole terminations.
- PILC STA Paper Insulated Lead Covered Steel Tape Armoured
- PILC SWA Paper Insulated Lead Covered Steel Wire Armoured
Cable joints can be modified to include armour continuity for aluminium wire armoured (AWA) cables – to order cable joints suitable for armoured cables use SPAJ part references.
Options include transition (PILC to XLPE) and transition trifurcating (3 x single core PILC to 3 Core XLPE) cable joints – contact us to discuss your requirements.
The following enables the joint kit selection for 11kV single core cables:
SPS 11kV PILC Cable Joint – Order Code | Cable Joint Kit Range – Single Core Cables |
SPJ 12P-50-95-1 | 50-95sqmm |
