The frame is assembled by new type 8MF cold-bend steel with rigidity and bearing capacity meeting installation requirement of electrical components. Installation holes of E=20mm and E=100mm are provided on the frame toimprove the assembly and universality of products. Main bus is arranged on the top of the switchgear adopting ZMJ-type bus clamp in the structure of block combination. It is molded by high flame-resistance PPO material through thermal injection with high mechanical strength and insulation degree, and can bear current with effective value of 50kA and peak value of 105kA. The long-term allowable temperature of thermal stability impact force can reach 120%℃.
