High Voltage Busbar Heat Shrink Tubing
The high voltage busbar heat shrink tubing have good insulating and flame-retardent properties. It can protect the busbar from the corrosion of chemical gasses, lower operating temperature and resist to the flashover.
Standard color: red, yellow, green
Shrinking properties: Longitudinal shrinkage 10%(max), diameter shrinkage 50%(min)
Minimum shrinking temperature: 120℃
Operating Temperature: -40℃~+120℃
Application: The protection and insulation of the busbar of the switchgear cabinet in the power station.
