Product overview

S13-M type series three-phase oil-immersed distribution transformer is a national science and technology，new products on the basis of the new series products of the integrated structure design to develop the design of the dominant idea is to satisfy the reliability of products，improve the performance of the product design according to the actual situation of the new integrated products，readjust some loss coefficient and structure，make the loss design value conforms to the real side，at the same time，the optimization design，the reasonable proportion of copper，iron，to minimum the cost of materials，reasonable structure.Core，high permeability，low loss of high quality high-performance silicon steel，reduce no-load loss and no-load current.Winding and body，and a full range of high voltage winding adopts layer structure，500 kVa and below products，low voltage winding layer structure，（unsegmented，continuous），more than 630 kVa and low voltage products with new type spiral:body assembly summed up the new integrated distribution transformer mature experience，become a solid whole body is assembled，ensure that products meet the electrical performance and sudden short circuit when the mechanical strength requirement.

This series of products for the fully sealed structure to ensure that the transformer oil and the outside air isolation，prevent oil aging，improve the operation reliability of the transformer，the tank adopts corrugated tank in the tank wall under a long hole.

To promote oil circulation in corrugated sheets.This kind of oil tank has the advantages of simple technology，high mechanical strength，improved oil fluidity and heat dissipation，good welding effect and no easy leakage.
