Unless or otherwise specified the transformers will be connected as per Vector Group reference DYn 11 in accordance with International practice.
The core used is best quality cold rolled gain oriented and laser processed silicon steel sheet. They provide low iron loss,low noise, compact size and have the best performance for high efficiency transformers.
We use high quality conductor of copper/aluminium in our products. Round or rectangular copper/aluminium wires/strips ribbed with thermally upgraded insulating paper are applied in oil immersed transformers. The winding have a compact size,excellent heat transmission, low load loss, high lighting impulse resistivity and outstanding anti-short-circuit strength.
