Electric furnace transformer is mainly used for steelmaking, copper smelting, calcium carbide, ferroalloy, silicon compound, melting iron and so on.

Product advantages

1. The iron core of our furnace transformer is made of high quality cold rolled oriented silicon steel sheet, which is formed by longitudinal shearing line and transverse shearing, with small shearing burr. The iron core is stacked by multi-step process with full oblique joint, thus effectively ensuring the lower no-load loss, no-load current and noise of the product.
2. The winding of our furnace transformer is made of high purity semi-hard oxygen-free copper paper wrapped flat wire, and the winding insulation is made of high quality insulating paper board, which effectively improves the resistance to sudden short circuit of the coil. The inner coil is directly wound on the insulating cylinder, all coils are made of inner and outer bracing strips, all bracing strips and pads are chamfered, the electric field is uniform, and the reliability is enhanced. Coil assembly adopts synchronous jacking system, which effectively controls the axial size of the coil, ensures the axial compression force of the coil, and effectively reduces wire loss.
3. The rated power and voltages can be customized according to the client’s requirement.
4. Low loss, low noise, low temperature rise, high reliability, free hanging core and no leakage.
5. The tank of furnace transformer is folded plate and flat-topped oil tank and the tank walls is using wide steel plate, which can reduce the welded seams, make the transformer looks simple and good, and improve the mechanical strength of the transformer. The tank can withstand the standard requirements of the positive pressure and pass the mechanical strength test of the vacuum degree.
