Heat-Shrink Insulation Breakouts

Seal and insulate the point where cable cores separate at a termination. Designed for medium-voltage applications up to 36 kV, the heat-shrink breakout uses a hot-melt adhesive coating and is available in configurations for two to five cores.

For cable-core separation at terminations
Two- to five-core configurations
Adhesive coating for moisture sealing
