Distribution transformer is usually pole mounted or installed in distribution station for daily lighting and factory power whose LV output up to 0.4kV. The rating of transformer is up to 2500kVA, and primary voltage up to 35kV. Hermetically sealed distribution transformer manufactured by us are with corrugated radiators. The corrugated tank as a thermal expansion and contraction components enable the transformer oil completely isolated with the atmosphere.
Distribution transformer with primary voltage range of 6,10,10.5,20,35kV can be manufactured according to the requirement of client.
- Distribution transformer is optimally designed by patented technology and software. Its performance parameters and requirements meet the Chinese National Standards GB1094, GB/T6451, GB/T25446 and so on.
- The core is made of high quality cold-rolled grain-oriented silicon steel sheet which produced in step-lap technology by automatic core lamination line from GEORG Germany.
- The oil tank is corrugated type and fabricated by Germany
GEORG ultra corrugation tank wall production lines. Tank surface pre-treatment liquid and coating powder adopts international top brands. The tank is degreasing, pickling, phosphorated, electrophoresis by automatic GEORG production lines, then power spary coating and heat-solidify. The tank of transformer is highly corrosion resistance.
- The H.V winding of distribution transformer is made of high strength enamelled wire or paper-insulated wire, the
L.V winding is made of high strength enamelled wire or paper-insulated wire and copper belt winding, which offers uniform distribution of ampere-turns, reasonable insulation structure so as to offer high ability to withstand short-circuit.
- 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.
