S13 series 6~10KV double winding oil immersed power transformer

S13-M-10KV

Fully sealed oil-immersed distribution transformer

S13-M type three-phase oil-immersed distribution transformer is a national science and technology product on the basis of new design S9 with the dominant idea to satisfy the reliability , improve the performance of the product design according to the actual situation of the new integrated products , adjust some loss coefficient and structure ,  make the loss design value conforms to the real side , at the same time , optimization design , the reasonable proportion of copper, iron , to minimum the cost of material , reasonable structure .

The core , high permeability , low loss and high performance silicon steel ,  reduce the no-load loss and no-load current .

Winding and body,  full range of high voltage winding adopts layer structure , the products of 500KV and below ,  low voltage winding layer structure , more than 630KVA and low voltage products with new type type spiral , body assembly summed up the new integrated distribution transformer mature experience , become a solid whole body , ensure the products meet the electrical performance and mechanical strength requirements when sudden circuit breaker happened .

The full sealed structure ensure the isolation of transforer oil and outside air  , prevent oil aging , improve the operation reliability , The tank adopts corrugated tank , there is the hole in the tank wall to promote the circulation in corrugated sheets . This kind of oil tank has the advantages of simple technology , high mechanical strength, improved the heat dissipation , good welding and it is not easy to leak  .
