Product Main Features

1. Corrugated tank design, not only beautiful, and improve the overall mechanical strength of the tank, box and box along the use of welded structure, reduce oil penetration point, to ensure long-term quality of operation.
2. The heat dissipation part of the transformer is installed in a separate space, isolated in the mailbox, significantly improved the overall cooling effect.
3. Low-voltage coil wire using CTC semi-hard copper wire to improve the mechanical strength.
4. Selection of vacuum on-load switch, to ensure product safety and reliability of operation.
