Strong overload capacity, allowing overload of 2 times for 2 hours and overload of 1.6 times for 7 hours without affecting the lifespan of the transformer.

By using elbow type connectors, it is very convenient to connect high-voltage incoming cables and can be used as a load switch in emergency situations, allowing for live plugging and unplugging.

Adopting dual fuse protection, the plug-in fuse (BAY-o-net) is a dual sensitive fuse (temperature, current) to protect against short-circuit faults occurring on the secondary side of the transformer box. The backup current limiting protection fuse (ELSP) is used to protect the high-voltage side from internal faults in the transformer box.

Transformers generally use high ignition point oil (FR3).

All components such as fuses for high-voltage load switch protection are placed in the same oil tank as the transformer core and winding.
