Mine Explosion Proof Mining Transformer CoreMine Explosion Proof Mining Transformer Winding
The low voltage winding adopts the whole section of copper foil, which is wound on the special low-voltage foil winding machine with the F-grade insulation. The foil coil solves the outstanding problems such as low voltage, high current coil winding, high short-circuit stress, unbalanced ampere turns, poor heat dissipation effect, windingspiral angle, unstable manual welding quality and so on. At the same tim-e, the winding ends of our company aresealed with resin, cured and formed, moisture-proof and antifouling. The lead copper bar is automatically welded byargon arc welding.
