13.8kv/50000 Kva Step Up Transformer

With our sound facilities, we are engaged in manufacturing, exporting and trading a massive gamut of 13.8kV/50000 Kva Step Up Transformer in Shanghai, Shanghai, China.

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 transformera 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 a no-upper yoke lappeda 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 a leg two-yoke core a strong and flat integral one with good verticality precision, this effectively improves no-load performance and reduces noises.
