Product Introduction

OVERVIEW

 

The core of 110kV power transformers is made of high-quality silicon-steel sheets, and laminated by steps. It is advantageous in low loss, low noise, and high short-circuit withstand capacity, etC. Now it is wildly used in power station, power plant, and gets high praise from them. SZ11-63000/110 transformers have passed a complete set of National tests and the short-circuit withstand capacity test.
