Product Introduction

As the urban and rural power grid construction and renovation projects continue to deepen and improve, and China’s demand for energy efficiency is increasing, our company developed S13-M-30~1600/10 series three-phase oil-immersed full-sealed distribution transformer according to the current state power grid renovation and the market demand. The series of products have the advantages of remarkable energy saving, advanced technology, reasonable structure, good electrical and mechanical performance, reliable operation, and so on.


Product Features

The transformer core adopts laminated structure, which is the traditional structure of transformer in China as well as the prevailing core structure worldwide. Wound by paper-wrapped flat copper wire or enamelled wire, the high voltage winding adopts a multi-layer cylinder structure. The diamond dotted paper of high density and purity is used for interlayer insulation. Reasonable arrangement of oil duct can help dissipate heat. The HV winding is directly wound on the LV winding and the outermost layer is packed with tight belt. Both ends of the windings are wrapped with weftless tape so as to enhance the mechanical strength of the windings and improve the ability to withstand short circuit.

The LV winding uses paper-wrapped flat copper wire structure. As the copper wire in the arc is more elastic during winding, the tension of the copper wire must be sufficient to tighten the winding. The copper wire needs forging on the flat plates to ensure that the radial deviation is under control. The radial dimensions need measuring upon completion of winding. Those with excessive deviation are corrected with sizing equipment. The inside of the winding is supported by wooden mould, preventing the winding from deformation.
