Product Description

The 110KV power transformers have the characteristics of low loss, low temperature rise, low noise, low partial discharge, and strong short-circuit resistance, thereby saving a lot of electrical energy loss and operating costs. This product is mainly used in power plants, substations, and large industrial and mining enterprises.


Product features

1. The product has the characteristics of low no-load current, low noise, high heat dissipation efficiency, and high mechanical strength of the fuel tank.

2. It can reduce the internal temperature rise of the coil and extend the lifespan of the insulation material.

3. The product adopts special processes during transportation and use to prevent displacement and loosening.
