DUWAI HB1.5 - Busbar Insulating Heat Shrink Tubing (Withstand Voltage Up To 10kV)
APPLICATIONS
HB1.5 is made of polyolefin. The flexible material make it very easy for the operator to process bent busbars. The environmental friendly polyolefin material can provide reliable insulation protection up to 10 kV, avoiding the possibility of flashovers and accidental contact. The use of HB1.5 to cover busbars can reduce the space design of the switchgear and lowers the cost.
