DETAILED DESCRIPTION - A power switch cabinet has a shell. The inner wall of shell is provided with a through-ventilation hole. The through-ventilation hole is provided with more than one. The bottom of shell is provided with support. A mirror is arranged on support. A transparent window is arranged on sidewall of bottom of shell. One or more heat-absorbing sheets, temperature sensor and circuit board are arranged inside the shell. The temperature sensor is connected with circuit board. The outer surface of housing is provided with display device. The display device is connected with circuit board. The top of shell is provided with air outlet. A blower is arranged in air outlet. A flashing plate is arranged above the air outlet. The shell comprises 24 pts. wt. graphene, 20 pts. wt. polypropylene, 38 pts. wt. carbon fibers, 30 pts. wt. silica gel, 28 pts. wt. quartz sand, 34 pts. wt. kaolin, 18 pts. wt. magnesium bicarbonate, 20 pts. wt. diphenyl ether, 16 pts. wt. methyl ethyl ketone, 24 pts. wt. phenolic resin, 20 pts. wt. zinc oxide, 20 pts. wt. stearic acid, 22 pts. wt. styrene, 22 pts. wt. aluminum and 20 pts. wt. copper. The temperature sensor is provided with wireless transmitter. The display device is provided with waterproof membrane. The blower is connected with solar panel. The shell is prepared by adding 24 pts. wt. graphene, 30 pts. wt. silica gel and 28 pts. wt. quartz sand to jet mill, stirring mixture with mixer, and injection molding mixture with injection molding machine to obtain particles, stirring 22 pts. wt. styrene and 20 pts. wt. polypropylene, adding mixture to boiler, heating mixture at 70 degrees C, adding 34 pts. wt. kaolin to calciner, calcining mixture at 700-800 degrees C and heating rate of 10 degrees C/minute, calcining mixture at 800 degrees C for 2 hours, heating mixture for 1 hour, naturally cooling and discharging mixture, feeding 24 pts. wt. phenolic resin, 20 pts. wt. zinc oxide and 20 pts. wt. stearic acid to melting furnace and heating mixture at 600 degrees C for 5 hours, adding 38 pts. wt. carbon fibers, 22 pts. wt. aluminum and 20 pts. wt. copper to steelmaking furnace, heating mixture at 1200 degrees C for 3 hours to obtain molten material, mixing raw materials, adding 18 pts. wt. magnesium bicarbonate, 20 pts. wt. diphenyl ether and 16 pts. wt. methyl ethyl ketone, stirring mixture in mixer, feeding molten material to injection mold, curing for 36 hours, demolding and normal-temperature curing for five days.
