Dry type transformer Energy efficiency grade I dry type transformer

Energy efficiency grade I dry type transformer

Rated voltage	0.4kV-35kV
Rated capacity	50kVA-2500kVA
Application scenarios	The product is widely used in power transmission and transformation systems,such as hotels,restaurants,airports,high-rise buildings, commercial centers,residential quarters and other important places,as well as subways,smelting power plants and other harsh environments.

Overview

Compared with energy efficiency level ll products, the energy efficiency level I has more obvious advantages in terms of performance. The no-load loss is reduced by about 20%on average, and it is safe and fireproof. It can be directly operated in high-load power-consuming places. It is an ideal choice for factories, hospitals, tunnels, airports, powerstations and so on.
