Heat Shrink LV Cable Breakout, 2 to 7 Core, up to 1.1 kV (Insulcore)

Where the outer sheath of a multi-core cable is stripped back and the cores fan out, the crutch is the weakest point for water entry. Gala's INSULCORE LV breakout seals it.

The breakout is a moulded cross-linked polyolefin boot with a body that fits over the cable sheath and one finger for each core. It is lined with hot-melt adhesive and supplied expanded. Slide it over the crutch with one core through each finger, then shrink it with a propane (preferred) or butane torch, starting at the centre of the body and working out towards the fingers. It recovers above 125 °C. When fitted correctly the surface is smooth and adhesive shows at the ends of the body and fingers, giving a permanent moisture-proof seal at the crutch. Work only on de-energised circuits.

The range covers 2, 3, 4, 5, 6 and 7-core PVC, XLPE, rubber and PILC cables rated up to 1.1 kV, including five sizes with two different finger sizes for cables whose cores are not all the same size. Each code states supplied and recovered body and finger diameters, so the breakout is chosen from the sheath diameter and the core diameter of the cable. Custom dimensions can be made on request.

Breakouts are used in LV cable terminations and at cable entries into panels, motors and equipment. The material is cross-linked polyolefin with a guaranteed 12 N/mm2 tensile strength and a continuous temperature limit of -40 to +100 °C. Gala is an ISO 9001, ISO 14001 and ISO 45001 certified manufacturer.
