A practical guide to selecting suitable heat shrinkable cable terminations based on voltage ratings, cable specifications, installation locations, and operating environments to ensure reliable electrical insulation and long-term performance.

The​‍​‌‍​‍‌ picking of thin-wall heat-shrinkable tubing needs thorough analysis of the size of the part being protected, the shrink ratio, the thickness of the wall after the shrinking process, the properties of the material, and the real-life working conditions, in a bid to guarantee a good fit when it is put in a new place, and insulation protection of the ​‍​‌‍​‍‌part.

CCMT applies continuous expansion technology to manufacture heat-shrinkable cable accessories, including insulation tubes, stress control sleeves, and semi-conductive composite tubes, with thicknesses up to 6.0 mm to support diverse product specifications and customization needs.

A 2.5:1 shrinkage ratio offers greater size adaptation flexibility than a 2:1 ratio, but proper busbar insulation selection still depends on busbar dimensions, voltage requirements, and wall thickness after shrinkage.

Tri-layer heat shrink tube uses a co-extruded composite structure of semiconductive layer, insulating layer and elastic layer, taking into account electrical stress control, insulation protection and elastic lamination. It is suitable for insulation treatment of 6 - 36kV power cable joints and up to 42kV power cable joints.
