20KV Class Three Phase Oil-Immersed Distribution Transformer
1.The core is made of high quality cold rolled grain oriented silicon steel sheet, 45°three-stage fully oblique seams, no punching, and the core column is brushed with polyurethane varnish for curing.
2.The coil is made of oxygen-free copper conductor with reasonable structure, which improves the resistance to sudden short-circuit.
3.Increase the effective support of winding end face, so that the short-circuit resistance of the winding is further improved.
4.Oil storage cabinet is cancelled, and the wave fin of corrugated oil tank replaces the oil pipe as the cooling element, the wave super can expand and contract with the volume expansion and contraction of the transformer oil, the transformer oil is isolated from the atmosphere, which prevents and reduces the deterioration of the oil quality and the insulation dampness, and strengthens the operation reliability, and the normal operation is free of maintenance.
