1. 

Have good ability withstand short-circuit

a.

The dry-type transformers are casted with epoxyresin,which are made of high quality materials by means

 of a strict process with advanced production and testing devices.

b.

The product features high reliability and long service life.In accordance with different operation environment,

 it can be equipped with different protection casings or without casing

c.

It can replace the oil-immersed transformer and be used in the high buildings,business centers,airports,

tunnels,chemical plants,nuclear power stations and watercrafts ect

2.

Low loss, low noise, high reliability

3.

Reliability: All in-service product have no damages
