Cable Joints

HV cable joints are suitable for jointing medium/high voltage (MV-HV) 33kV 3 core polymeric cables (XLPE EPR) to DIN VDE 0276-620, BS6622, BS7870-4.10 and other international cable standards.

33kV cable joints use heat shrink tubes and suit 33kV cables with 16sqmm to 300sqmm 3 core conductors (copper Cu and aluminium Al) – suitable for power cable jointing, repair and installation in ground, air or cable ducts.

Also available for MV-HV power systems a complete range of 33kV cable terminations can be supplied in heat shrink, cold shrink or EPDM rubber (separable connector) type for connecting 33kV cables into air, oil or gas insulated high voltage electrical equipment and switchgear.

33kV Joints

33kV heat shrink cable joints suit both armoured and unarmoured cables – this includes high voltage industrial power (XLPE BS6622 BS7835 with steel wire armour SWA and/or lead sheath) and marine offshore ship cable (EPR BS6883 with galvanised/phosphur wire braid) and copper wire or copper tape screen.

Options include transition (PILC to XLPE) and transition trifurcating (3 x single core PILC to 3 Core XLPE) cable joints at 33kV – contact us to discuss your requirements.
