Heat Shrinkable Tube
1. General Introduction
The heat-shrinkable tube is made from good insulation and anti-flaming material. It is mainly used for busbar insulation protection in low-voltage and medium-voltage switchgears. It can be applied to avoid lapping of corpus alienum, prevent short-circuit or flashover. The products are used in 1kV, 10kV to 40.5kV electrical system.
