WE ARE LOOKING FOR AGENRTS!!!
 

Headquartered in High-Tech Industrial Development Zone with 50.000 square meters

Factory area :130000 square meters ;  Monthly Capacity : 6000 pcs 

Our products ranges from 5KVA to 2500KVA 

(Voltage regulators / stabilizers, gensets, tranformers,UPS etc)

INTRODUCTION

Drytype transformers refer to the serials of transformers whose core and windingsare not immersed in the insulating oil .Cooling ways are divided into natural air 
cooling (AN) and forced air cooling (AF).

When designed with natural air cooling, transformer can be long-term continuously operated at the rated capacity. When designed with forced air 
cooling, transformer 
output capacity can be increased. Dry-type transformers are suitable for intermittent overload operation, accident or 

emergency overload operation;

Due to overload loss and impedance voltage increase largely , the transformer is not in an economical operating state, so it should not be run at continuous 
overload state for a
 long-term.

 

APPLICATION

Highrise buildings, commercial centers, city squares, hospitals, schools, airports, 
railway stations, port 
terminals, subway, power plants, oil field, chemicals, tunnels 
and other places.
