Product Description

Electrical Power Transformers,10KV, 20KV 35KV High Voltage 3 phase Safety Oil Immersed Type Transformer
 

1.Product introduction

Three-phase high-voltage power  transformers can be widely used in industry, such as start spot welding machine, automatic welding machine, butt welding machine, straightening machine, steel wire rolling machine, diffusion welding machine, seam welding, roll welding, touch welding, row welding machine etc.

 

 

2. Normal operating conditions

Three-phase high-voltage power transformer should be able to work normally under the following conditions:

a) Altitude: not more than 1000m;

b) Ambient temperature: -15 ºC ~ + 40 ºC

c) The relative humidity of the air does not exceed 95% (at + 25 ºC);

d) In a gas or steam environment without damage to insulation;

e) Used in explosive environment without methane coal dust.
