132kv Prefabricated Distribution Transformer Substation Explosion Proof

132 Kv Emergency Vehicle Mounted Transformer Substation / Prefabricated Substation

It is the first vehiclemounted movable substation in China. It has been sent to Iraq in Dec 2008. The product which has 132KV voltage class and 16000KVA capacity is completely researched & developed, designed and amnufactured by ourselves.

>> Divided into HV part,main transformer,LV switchgear Room.
>> HV Switch adopts ZF10-145(L) as main switch,barely mounted on a semi-trailer.
>> LV side switchgear,control power,DC panel and control protection device.
