product description
Feature of Fully Sealed Oil-Immersed Distribution Transformer
A new insulating structure is used in the body of the 10KV series of fully sealed oil-immersed distribution transformer by ZTelec Group, significantly improving the ability to withstand short-circuits. The iron core is made of high-quality cold-rolled silicon steel sheet, and the winding is manufactured in the structure of multi-layer cylinder or foil. All of fasteners are treated with special anti-loose technology. The product has the features of high efficiency and low loss, which can save a lot of power consumption and operating costs, and also has significant social benefits. The 10KV series of fully sealed oil-immersed distribution transformer are the high-tech products promoted by China.
