Three Phase Cast Resin Dry Type Transformer For Powe Transmission Plant


Cast Resin Dry Type Transformer Utility :

With excellent performers, it can overcome those harsh operation conditions: high altitude, high humidity, high temperature and large temperature difference.
In daily life, it is exactly suitable for the places like government offices and bureau residential area and other areas that strictly demand of special require for fire proof.
Rising the challenge of large load fluctuation or long time overload places, it can be widely used in some places, for instance, urban rail, metallurgical industries, power plants, shopping mall and so on.

Cast Resin Dry Type Transformer Characteristics:

It has effect of cooling capacity and high performance such as moisture proof and light shock resistance.
It meets the needs of environmental adaptability and lighting shocks, strong resistance to thermal shock, anti-cracking and recycling.

Safety:


It adopts NOMEX insulation systems in the main insulation, inflaming retarding, explosion proof and so on.
Vacuum pressure impregnation curing process, high mechanical strength, withstand short-circuit, safe and reliable.


Cast Resin Dry Type Transformer, Low Noise, Low Loss and Low Partial Discharge.
