◆ Product Characteristic
   The epoxy resin cast dry type transformer of Special Transformer Company of MINGYANG Group is made is made with abroad advanced technology, it includes the following characteristics:
·Low local discharge
      As the coil is cast in vacuum state, the air bubble produced in coil can be prevented efficiently, the local discharging value fully accords with relative national standard.
·Strong capability of lightning impact
      The lightning impact voltage that affects the insulation of transformer windings along the initial voltage distribution of windings, the foil type windings initial voltage distribution approaches to linear one, therefore, the transformer manufactured by us has good ability to resist the lightning impact.
·Good performance of anti-drying crack
      The transformer manufactured by us is made of packing type resin and designed into the structure of full copper oil, the coefficient of insulation material is the similar to the that of thermal expansion of copper conductor, so the coils can be prevented cracking efficiently. The transformer has been done kind of anti-crack tests, such as cold/hot alternation test, thermal impact test, rapid aging test, etc, and the test result demonstrates that our technology can meet the requirements of service occasions like low temperature, high temperature and large range of variable temperature, as well as anti-crack after the transformer runs for a long time.
·Strong over-load capability
      If the transformer of same capacity whose load consumption is equal, the sectional ared of copper foil will be increased correspondingly, and the volume will be extended with the sectional area that requires more packing resin, therefore, both the thermal capacitive property of windings and short-time over load capability of transformer are quite strong.
·Good flame retardancy
        The transformer has visible features such as free-maintenance, moisture-proof, anti-damp and hot, flame-retardant, self-extingushing, etc., besides, its stuffing type resin casting technology is good for environmental protection, When burn by the electric arc at high temperature, it will not product any noxious gas. The superior flame retardancy is proved in the burning test.
       The product has good ability to adapt to environment, on the basis of European Hd464 standard, it reaches the environment class E2, weather-resistant class FC2, flame-retardant class F1, it can be widely used in fields or locations where service conditions are rather atrocious such as commercial area, under ground, power plant, steamship, offshore drilling platform, etc.
· Low noise
       Because of special structure and design, the noise produced by transformer is reduced greatly, compared with the noise value stipulated at national Specialized Standard, its whole noise level is lower than it for more than over 10-13dB(A).
· Low consumption
       Compared with“8”character type products,SCB9 series has better economic benefit, its total consumption is reduce for10~15% in average.
