Container type unitized substation


Container type unitized compact substation

Container type unitized CSS compact substation is a complete type tested per latest IEC standard 62271-202 which is comprising a outdoor enclosure containing medium voltage (MV) switchgear, power or distribution transformers, low voltage (LV) switchboards, busbar or cable connections and auxiliary equipment to feeder elctric power by a step down power & distribution transformer from medium voltage systems.

The container type CSS compact substation is easy for transpotation and installation, high quality and strong enough for loading and lifting.

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.

36kV/40.5kV Prefabricated Substation

36kV/40.5kV Prefabricated Substation Characteristics

This type substations are the HV side 40.5 kV, LV side 0.4-12 kV and 3 phase outdoor completeequipment .It is wide used in cities , towns ,factories and oil fields, wharfs etc. It is also used insome construction sites. The characteristics are small volume, convenient installation, low cost,high automation safe and reliable operation. Substation is combined with HV switch room,LVswitch room, relay room and transformer room.
