20kV Distribution Transformer

20kV Distribution Transformer

General Introduction:

This product has advantages of multi-function, reliable operation, easy for maintenance,highly integrated,fast installation,elegant features.it`s very popular in construction site,stations,docks,mining and oil industries,and other sites requiring temporary power supply.

Product characteristic:

1. 20kv 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.

It adopts advanced electromagnetic design software, and meets IEC60076, GB1094, GB/T6451, GB/T25289-2010 standards. Without such device like conservator, air breather..., so it ensures that the transformer oil is not in contact with air, improving the anti-oxidation capacity of the transformer oil and delaying its aging. The core is made of high quality cold-rolled grain-oriented silicon steel sheet, with laminated structure miter joint, so as to reduce the no-load losses and no-load current. The tank is a corrugated type, the corrugated fins can swell and shrink with the change of transformer oil, so that the pressure can be maintained inside the tank, increase its reliability and anti-corrosion capability. The coil of distribution transformer, wound by high intensity enameled wrapped conductors with good Ampere-Turn balance and reasonable insulation structure,has a strong short-circuit withstand capacity. The distribution transformer adopts the free-untanking structure. With sealing material parts made of high quality acrylic rubber, it can effectively prevent against light-aging and heat-aging.
