Product Introduction:

      The series dry type transformer with large capacity, low wear and tear, reasonable structure, stable output voltage and safety.

       Dry-type transformer

      the series transformer are featured with large capacity, low loss, reasonable structure,stable output voltage and etc,. and are widely used in power supply, electronics, lighting,rectification,voltage conversion of imported equipment and etc,special applications areadditionally designed

Advantage:

      Inner iron core uses high quality silicon steel slice,the main materiala are

      Z10 Z11,27QG130.We choose material with high magnetic permeability,low loss to meet the requirement of  customer and Using condition, which will bring transformer to a best situation. 

      Inner insulating material adopts NOMEX made by du Pont de Nemours(USA),it has the characteristics of insulate on high temperature,inflaming retarding and moisture-resistance.

 

      Its voltage wave shape steady ,high impedance,low loss,low noise and it has over- load temperature protection small circle current in parallel.

 

Parameter characterstics:

1.Output voltage tolerance ±1%

2.The rate of output wave distorion No distortion(compare to input wave)

3.Insulation Class  H

4. Efficiency Above 98%

5.Frequency 50-60HZ, according to the requirement between 30HZ-400HZ

6.Capacity 1KVA-500KVA
