GNEE New Material Oriented Electrical Steel For Transformer

Epoxy cast resin dry transformer is cast under vacuum with thin insulating bands automatically. The core is made of a high-permeable grain-orientated silicon sheet and cast with imported epoxy resin. The coil is reinforced with glass fiber and cast under vacuum with filler epoxy resin. It has good mechanical properties, is free of crack and inner bubble, and has a low local discharge, high reliability, and long service life. The high and low-voltage systems are cast under vacuum, thus the coil will not absorb moisture, the clamps of the core are subjected to corrosion-resistant treatment and it may run under high temperature or other serious environments.

Epoxy cast dry-type transformer can be used as a replacement product for oil-immersed distribution transformers. It is especially suitable for important places such as urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subways, underground power stations, laboratories, stations, docks, airports, combined substations, etc.

Transformer Electrical Steel

Transformer Grain Oriented Electrical Steel

Grain Oriented Electrical Steel for Transformer Function Characteristics:

1. The low-voltage coil is wound with foil, and the foil winding is solidified into an integral structure after end sealing. The high-voltage coil is poured with epoxy resin in a vacuum state, and after curing, it forms a solid long cylindrical whole. High mechanical strength, small partial discharge, high reliability, high resistance to short circuit and lightning strike.

2. The resin layer inside and outside the coil is thin, and the heat dissipation performance is good. The cooling method generally adopts air natural cooling (AN). For transformers of any protection level, an air cooling system (AF) can be configured to improve short-time overload capability and ensure safe operation.

3. Low loss, good power saving effect, economical operation and maintenance-free.

4. Small size, light weight, small footprint and low installation cost. Oil drain pools, fire-fighting facilities and backup power sources etc. do not need to be considered.
