Cable Joints

HV cable joints are suitable for medium/high voltage (MV-HV) 11kV single core polymeric cables (XLPE EPR) – cable joints use heat shrink tubes and suit 11kV cables with 25sqmm to 800sqmm single core conductors (copper and aluminium).

11kV Joints

11kV heat shrink cable joints suit unarmoured and armoured cables – this includes high voltage industrial power (XLPE BS6622 BS7835 with aluminium wire armour AWA) and marine offshore ship cable (EPR BS6883 with galvanised/phosphur wire braid) and copper wire or copper tape screen. Suitable also for BS7870 triplex cables.

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:
