HB3 - Busbar Insulating Heat Shrink Tubing (Withstand Voltage Up To 36kV)
Applications
Heavy wall HB3 has reliable insulation protection. It can provide insulation and anti-flashover protection for busbars up to 36kV. The cross-linked polyolefin material has UV resistance and flame retardant properties, and can provide long-term insulation and withstand voltage protection for busbars in harsh high temperature and chemical environments.
