SG(B) Series Non-sealed H-class Dry Transformers

Non-sealed H-class dry type power transformers, possess many good features such as safety, reliability, and energy saving, fireproof, flameproof, simple maintenance. The design is advance, the structure of the product is reasonable and the outline is fine. The main performances of the products are much better than the National standards, it keeps excellent electric performance and mechanical property during the whole life of the transformer, it is adaptable for application on heavy humidity and severely pollute places which are near to lake, sea and river, as well as, high demand-fireproof, heavy load capacity places, such as: high buildings, airport, station, port, underground, hospital, electrical power station, metallurgy, shopping centre residential area and petroleum power station, metallurgy, port, underground, hospital, electrical power station, metallurgy, shopping center residential area and petroleum, chemical industry, nuclear power station, unclear-powered submarine. 1. There is no any partial discharge. Any cracks and reduced insulation level on SG(B)10 series transformers under operation is whole effective life term due to the structures of windingswith keep improving design and vacuum pressure impregnating technology. 2. The Continue disk type structure is applied to high voltage windings and foil structure isapplied to low voltage windings. In other hand, overall vacuum impregnating and solidifying process will treat windings. At the same time, the insulation spacers, which are made from laminated insulation materials with high strength should be applied in the high voltage windings so that SG(B)10 series dry type transformers are able to operate with excellent bearing suddenly short circuit ability. 3. Incombustible ability, flameproof, innocuity, self-extinguish, fireproof. 4. Small dimension light weight, low noise.
