Product Overview
The core of 110kV power transformers is made of high-quality silicon-steel sheetsand 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 acomplete set of National tests and the short-circuit withstand capacity test.
