Main Designation Characteristics

The crust of the substation is designed according to the foreign advanced technology and physical reality. We provide many kinds of crust material such as aluminum alloy steel composite stainless steel board and non metal material(glass fiber).

The HV side use charge switch or vacuum circuit breaker. The transformer could be oil type hermetically-sealed type and dry type.

The proof of the box is double layers structure and between the layers is filled with foam. There are independent boards in HV and LV room, and in the transformer room will install auto thermal controller heater and cooling equipment.

Note: we offer special customized products according to client’s requirement.
