11kV triplex cables provide high voltage (HV) mains power distribution for utility and industrial applications – 11kV triplex cable consists of three single core high voltage cables in triplex formation according to BS7870 – 4.10. separable connectors are also known as screened elbow connectors or tee connectors.
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.

Heat shrink cable joints include straight, transition and branch types for XLPE, PILC and EPR single and 3 core cables – suitable for all types of polymeric and paper insulated medium/high voltage cables with/without steel wire armour or braid, copper tape/wire screens and copper or aluminium conductors up to 33kV.
