15kV distribution transformer(50kVA-10000kVA)

1. 15kV Oil immersed transformer 2. BIL 95kV/RMS 38kV 3. IEC60076 Standard 4. M4 High B Grade CRGO Steels

1.     Feature & Advantage:

       * Strong insulation system between HV and LV winding.

       * Higher reliability supporting structure, stronger short circuit withstand ability of transformer body.

       * Stronger rust-proof capacity of transformer tank surface.

       * Longer service life.

2.    Benefit:

      * Lower no load loss and on load loss,  energy saved, money saved during it running.

3.   Supply record:

       We are cooperating with plenty of  Electric companies and Electrical installing companies in China, Malaysia, Russia, Angolar, D.R.Congo, South Africa, Zambia, Ghana and Nigeria.  The annual sales of 2011 is around 15 million US Dollar.
