Single Phase Pole Mounted Transformer Core

The core is beveled and stepped for maximum performance and minimal bulk. After the magnetic steel is produced by the cutting machine, it is continuously cut into specific lengths by the automatic stacking machine, and then automatically stacked. The correct size is ensured during the entire stacking and assembly process to ensure the high quality of the product.

Pole Mounted Transformer Manufacturers 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.
