35kV electrical transformer

Brunstock’s series of 35kV transformers have low loss, low noise, protection against thunder and lightning with a high short-circuit withstand capacity. They are made in advanced assembly lines with carefully qualified and refined methods and equipment. These transformers have four remote functions:

1. remote communication
2. remote test
3. remote adjustment
4. remote control

Using remote control, from a computer, the power station does not require on-site supervision. Our 35kV series of energy-saving transformers have passed the identification test by the third party KEMA and ASTA (DNV) laboratory. The 35kV series of transformers are mainly used in urban and rural power
grids and other industries, mining, power transmission and distribution, new energy solar, wind farms and also agriculture projects.

35kV electrical transformer features

• The core is processed by the advanced method of vertical cut, horizontal cut, and stacking with stepped lap core and grade 3 seams. It disperses the air distribution and improves flux trend, thus decreasing the no-load loss, no-load current and noise.
• The core uses particular adhesives for the plate, press ring and silicon steel surfaces. The overall structure is designed with a range of measures that increase its mechanical strength.
• A new structure of HV and LV windings combine with a reasonable layout of oil duct and connecting areas to increase the mechanical strength and short-circuit withstand capacity.
• The tank is a bell type or core-lifting type, and the tank side is corrugated, with flowing lines, simplicity and a nice appearance.
