The feature

1. Strong overload capacity, allowing overload 2 times 2 hours, overload 1.6 times 7 hours without affecting the variable life of the box.

2.Adopt elbow type plug connector, can be very convenient to connect the high-voltage incoming cable, and can be used as load switch in emergency, can be charged plug.

3.Adopt double fuse protection, insert fuse is short circuit fault of double sensitive fuse (temperature, current) protection box.

4.Backup Current Limiting Protection Fuses (ELSP) are used to protect the high voltage side when a fault occurs inside the protection box.

5.Transformers generally use high ignition point oil.

6.All components used for high voltage load switch protection, such as fuse, transformer core and winding, are placed in the same oil tank
