It adopts a special design of magnetic circuit which has large space and magnetism density. It is made of aluminum wire or copper wire and the coil protection plate adopts the rolled high Mn steel plate that has good performance of wear-resistance. It also has the characteristics of light weight, low power consumption, high lifting capacity and long serving life.
This series has fine insulation structure. The insulation treatments adopt the vacuum drying & glue filling, which has improved the electrical and mechanical performance of the coils. The insulation grade can reach class special C.
