It is made of high-quality flame-retardant metal material, which has good fire resistance and heat insulation properties. It can effectively block external fire sources from damaging the internal electrical components and prevent internal fires from spreading to the outside.

[0031] The lifting plate 4 is located at the bottom of the cabinet 1 and separates the interior of the cabinet 1 into upper and lower areas. An electric push rod 10 is connected between the bottom of the lifting plate 4 and the bottom of the cabinet 1.

[0032] The lifting platform 4 divides the interior of cabinet 1 into upper and lower areas. This modular design effectively limits the spread of fire within a specific area and reduces fire damage in the event of a fire. Simultaneously, this structure facilitates the layout and maintenance of electrical components; the upper area can accommodate environmentally sensitive electrical components, while the lower area can house fire extinguishing equipment such as storage tanks 7.

[0033] In normal use, the lifting plate 4 can be lowered by the electric push rod 10 to expand the internal space, allow air circulation, and facilitate heat dissipation. When a fire breaks out, the lifting plate 4 moves upward to reduce the space and control the fire. At the same time, due to the reduced space, the amount of extinguishing agent sprayed can be reduced, improving the efficiency of use and controlling the fire.

[0034] Among them, a fan 5 is installed at the top of the lifting plate 4, which can play a role in heat dissipation under normal conditions.
