Aluminum specializes in the production of high purity 1070/1060/1050 aluminium foil for cast resin transformer, which has high conductivity and high annealing quality. The slitting is strictly controlled to ensure that the strip is free of cracks, roughness, scaling, and stretch marks, and the edge is burr free.
Aluminium foil for cast resin transformer winding combines simple technology with a high degree of electrical safety. Compared with other types of windings, the insulation bears less electrical stress. In traditional round wire windings, the inter-turn voltage can reach twice the inter-layer voltage. The layer of the foil winding has only one turn, so the electrical stress remains constant, and the winding can withstand high power frequency voltage and impulse voltage.
