HB2 - Heat Shrinkable Busbar Insulation Tubing (15~24KV)

HB2 - Heat shrinkable busbar insulating tubing (Withstand voltage up to 24kV)

Applications:
HB2 is made of polyolefin. The flexible material and inner lubricious coating make it very easy for the operator to process on bent busbars. The environmental friendly polyolefin material can provide reliable insulation protection up to 24 kV, avoiding the possibility of flashovers and accidental contact. The use of HB2 to cover busbars can reduce the space design of the switchgear and lowers the cost.
