Main features of box transformer
:
Strong overload capability, allowing overload for multiple times of an hour, and overload for multiple times of hours without affecting the life of the box transformer.
The elbow type plug connector is used to facilitate the connection of high-voltage incoming cables, and can be used as a load switch in an emergency, which can be unplugged and plugged in while the power is on.
Using double fuse protection, the plug-in fuse (B&&) is a double-sensitive fuse (temperature, current) to protect the short circuit fault that occurs on the secondary side of the box transformer. The backup current-limiting protection fuse protects the high-voltage side from faults occurring inside the box transformer.
Transformers generally use high ignition point oil.
All components such as high-voltage load switch protection fuses are placed in the same tank as the transformer core and windings.

Box-type substation
Structure:
The casing of the box-type substation is made of steel plate or alloy plate, equipped with a double-layer top cover and has good heat insulation. The shell and frame have all undergone anti-corrosion treatment and are suitable for long-term outdoor use. The shape and color can be coordinated with the environment. It is easy to install. There is a cable room under the foundation of the box-type substation, and there is a manhole in the low-voltage room to enter the cable room for work. From a volume perspective, European box-type transformers are larger in size due to the conventional switch cabinets and transformers installed inside. American box-type box transformers are smaller in size due to their integrated installation.
