Epoxy glass laminate sheet CEM-1 used in Switch cabinet
Switch cabinet is an electrical device , the exterior lines of switch cabinet enter in main control switch in the cabinet first, then enter the control switch, each branch is set according to its need.The main function of the switch cabinet is make the opening&closing ,control&protect electric equipment in the process of power generation, power transmission, distribution and power conversion.The components in the switch cabinet consist of circuit breaker, isolating switch, load switch, operating mechanism, transformer and protective device of insulation component.The insulation components in switch cabinet are supporting, bearing and isolating ,so the insulation materials are required to be: higher electrical strength, higher mechanical strength, stronger arc resistance and so on. The commonly materials used in switch cabinet are UPGM203 laminated sheet
Our products are mainly used as making of phase & end barriers,contact terminal support,terminal plate,insulating supports,bus bar supports and mounting panels.
