Product Description

Product Description

 

Product Name

IEC Electrical High Voltage 30kv 33kv 35kv 66kv 4/8/10/25mva 50/60Hz Large Copper Oil Immersed Power Transformer Price

Product Discription

Use steel straps or upper beam and side beam to form a solid frame structure to enhance the clamping force of iron core and the ability to withstand transportation impact. Strong short circuit resistance, beautiful appearance, reliable operation, low loss, low noise, reaching the advanced level of similar products abroad.

 

  

Product Discription

The SZ-20000/35 transformer prototype produced by our company has passed the sudden short circuit test conducted by the National Transformer Testing Center at one time. The longitudinal oil channel of the high and low voltage coils is conducive to heat dissipation, which can greatly reduce the temperature difference between copper and oil and the hottest temperature rise inside the coils.

We produces two series for option: on-load voltage regulation power transformers and off-excitation voltage regulation power transformers.

Product Features

Beautiful appearance, advanced technology and reliable operation.

Ideal equipment for factory, rural and urban transmission network centers.
