High voltage power transformer ratio range from 66KV to 220KV are the main products of SHENDA Electric which have many advantage both on quality and price. All the products has been fully tested and certificated before delivery.
Plenty of our products have been exported and applied in oversea markets regarding power plant, substation, mineral and ore industries.
Shenda electric is renowned and appreciated by its reliable products performance and integrated services.
Features:
1) Amount of local discharged: The apparent discharge amount is less than 80pC under 1.5 times of rated voltage;
2) Noise: Products of 63MVA and below is lower than 58 dB (AN);
3) Power loss: no-load loss is 30% lower than that of IEC standard;
4) Reliability: All in-service products have no damages or oil leakage occurred;
Application:
60 ~220 kV power system of power plant, substation, mining enterprise and etc.
Technologies:
Design: relative developed software are adopted in Electromagnetic calculations, strength analysis, leakage magnetic distribution, its electro-dynamic force and electrical insulation.
Manufacture:
Core: effectively upgrade transformer's no-load performance by below methods:
1) The core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet and the material is cut with advanced Germany Geoge GmbH automatic shear line with the cut burs controlled within 0.02mm.
2) The silicon sheet fabrication adopts "no-upper yoke lapped' technology and all lapped joints of the silicon sheet are 45 full-miters. The laminated core sheets are integrally pressed and adhered with epoxy resin to make the three -leg two-yoke core a strong and flat integral one with good verticality precision, this effectively improves no-load performance and reduces noises.
3) Bracing plates are used as support between coil leg and inner coil. The iron yoke is tied with epoxy resin-impregnated glass fiber band, and the lower section of oil tank is tightened with counter-pressure bolts. The upper iron and the upper section of oil tan
