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.
