USE - Electric power switchgear (claimed). ADVANTAGE - The electric power switchgear has simple design, and excellent durability and heat radiation effect. DETAILED DESCRIPTION - An electric power switchgear has a housing, vent provided on the inner wall of the housing through ventilation holes, bottom support and mirror holder. The bottom of the housing is provided with a transparent window. The housing has endothermic sheet(s), temperature sensor and circuit board. The temperature sensor is connected to the circuit board. The outer surface of the housing is provided with a display device. The display device is connected to the circuit board. The top of the housing is provided with a vent. The outlet is provided with an internal blower. The top outlet is provided with a flashing. The housing is made of 20-24 pts. wt. graphene, 18-20 pts. wt. polypropylene, 30-38 pts. wt. carbon fibers, 25-30 pts. wt. silica, 22-28 pts. wt. quartz sand, 28-34 pts. wt. kaolin, 12-18 pts. wt. magnesium bicarbonate, 16-20 pts. wt. diphenyl ether, 10-16 pts. wt. methylethylketone, 20-24 pts. wt. phenol resin, 18-20 pts. wt. zinc oxide, 16-20 pts. wt. octadecenoic acid, 18-22 pts. wt. styrene, 20-22 pts. wt. aluminum and 18-20 pts. wt. copper components.
