Project Description
Distribution Transformer: Oil immersed, 11kV & 33kV
Transmission and distribution system transmit electricity power to the end user by adjusting from far away power plants. Through high-voltage power transmission line, and then by few step-down transformer, the power is suitable for user’s application. Distribution transformers located in the vicinity of the end user will eventually reduce the voltage to a suitable rating. Distribution transformers are referred to those can reduce the voltage to the electrical equipment’s working voltage. Such transformers are used for daily lighting and industrial power. Generally, the low voltage is 0.4kV or below. The capacity of distribution transformer is small, generally 2500 kVA or below. And the primary voltage is 35 kV or below.
Hermetically sealed transformer is different from ordinary oil-immersed transformers due to no conservator installed. The corrugated fins on the tank act as radiator, which isolate the transformer oil from atmosphere.
Distribution transformer is optimally designed by means of CAD. Its performance complies with IEC60076 and Chinese National Standards GB1094 and GB/T6451.
The core is made of high quality cold-rolled grain-oriented silicon-steel sheet. The lamination sheets are produced by automatic step-lap core lamination line from GEORG, Germany.
The oil tank is corrugated type and fabricated with automatic tank production line from GEORG, Germany. Pre-treatment liquid and coating powder on the surface made by international top brand supplier. The tank is degreasing, pickling, phosphating, electrophoresis by automatic production line, then power spray coating and heat-solidify. The surface of transformer is corrosion resistance.
The winding of Distribution transformer is made of high strength varnished wire or paper-insulated wire, which offers uniform distribution of ampere-turns, reasonable insulation structure so as to offer high ability to short-circuit withstanding capacity of winding.
The active part applies core-free hanging structure. The gasket is made of high quality acrylate rubber which can inhibit ageing caused by sun and heat.
