Model Meaning

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.

The SZ-2000/35 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.

Product Features

Beautiful appearance, advanced technology and reliable operation.
Ideal equipment for factory, rural and urban transmission network centers.
