Product Description

35/0.4KV 1250KVA Three-phase fully sealed distribution transformer with copper winding

1.Product Description
S11-33kv oil immersed distribution transformer is widely used in industrial and mining enterprises, agriculture and civil buildings, and it's also suitable for places with many oil and chemical substances in petroleum and chemical industries. The low-voltage winding with the capacity of 630 ~ 2000kVA adopts the tubular or spiral structure, with high mechanical strength, balanced ampere turn distribution and good short-circuit resistance. The positioning structure is added to the transformer body to avoid displacement during transportation. At the same time, all fasteners are equipped with fastening nuts to ensure that the fasteners won't loose during long-term operation of the product. The product is free of maintenance and long-term operation.
