Three-Way Non Tracking Cable Breakouts

All dimensions are in mmDrawing depicts typical dimensionsE – as suppliedS – after free recoveryD,d – internal diameter without adhesive coating

Heat Shrinkable 3-way Non Tracking Cable Breakouts provide environmental seal to the cable crutch of 3 core Plastic and Paper insulated cables rated up to 36kV. The Breakouts are made from thermally stabilised cross linked non tracking and weather polymeric material.

The Breakouts are internally coated with water resistant mastic.
