On load tap changer (OLTC) is used with higher capacity transformers. HT side voltage variation is frequent and a nearly constant LT voltage is required. We use a high-quality conductor of copper aluminium in our products. Round or rectangular copper/aluminium wires are ribbed with thermally upgraded insulating paper in oil-immersed transformers. As a result, The winding has a compact size, excellent heat transmission, low load loss, high lighting impulse resistivity and outstanding anti-short-circuit strength. We have used the best quality cold rolled grain oriented and laser processed silicon steel sheets. Consequently, It provides low iron loss, low noise, and compact size. So, we have the best performance for high-efficiency transformers.
