SG(H)B10 Opening Dry Type Transformer

SG(H)B10 Opening Dry Type Transformer

By the strict control of material, optimized design, reasonable processing, SG(H)B10-100- 2500/10 series three phase opening type transformer produced by our company passed CTQC (certificate test of quality control) by State Transformer Quality Supervision& Inspection Center. To get reasonable structure and artistic appearance, NOMEX paper from DVPONT Co. and advanced VPI (vacuum pressure impregnation) technology are both used for the products.
      It owns the advantage such as weatherproof, no pollution, safe operation under high temperature, low partial charge and noise, ideal dissipation of heat, higher capability of overload. It is the new generation of dry transformer for the environmental protection. It is applicable to load center where requires more in fireproofing and security, such as airport, metro, power plant, metallurgy plant, hospital, high building, shopping center, residential area, etc.

Feature :

      1. Environmental protection :
         High quality H grade insulation material is used the product, there is no emission of hazardous gases under high temperature.
        Owing to the opening winding, it is convenient to take copper back for recycling after the service life.
      2. Reliable insulation system :
          NOMEX paper and ET-90 series H grade resin is chosen as basic insulation system, optimized design makes insulation system 180 degrees centigrade - 220 degrees centigrade, which is safe, steady and reliable under high temperature.
      3. Advanced processing technology :
          Adopting VPI technology and curing process under the high temperature, the lacquer film is bright and even, no cracking, the partial discharge is less than 5pc, with low noise.
      4.Overload capacity :
         H grade Nomex paper is used for insulation of winding in opening structure. Its dissipation of heat is faster and temperature rise is even, which shows higher overload capability.
      5. Stronger withstanding short-circuit capability :
          VPI process is carried out for H.V. &L.V. coils and pre-pressing device such as disc spring and silicon rubber is put on the end of coils to strengthen the mechanical strength for both coils and product, which improves its withstanding short-circuit capability.
      6. Weatherproof :
          The whole product is coated with H grade insulation lacquer twice.  Lacquer film has the good adhesion, mechanical strength and insulation performance without cracking. Therefore, it is weatherproof such as moisture, fog and dust, particularly in serious pollution.
