Applications
HB2 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 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.
