Switch cubicle special-purpose FR4 epoxy sheet / EPGC202 sheet specified for switchgear
Switch cubicle special-purpose FR4 epoxy sheetare made of woven glass cloth impregnated with epoxy thermosetting resin,laminated under high temperature and high pressure ,the woven glass cloth shall be alkali-free and treated by silane couple
Feature:
EPGC sheets(thermal class B-H),producer as per IEC60893-3-2,These sheets have excellent mechanical strength(the thermal state retension rate can reach over 50%)under medium temperature or the thermal state,as well as the stable electric properties(the insulation resistance after immersion reachers 10^12Ω)in high humidity condition .and also with higher voltage end urance /withstand voltage (over 35KV),parallel to laminated ,and they also have excellent flame retardant property.the sheets also passed the toxic and hazadous substance detection(RoHS Report)
Application:
used as the insulating structure parts in class B-h electric motors,electric equipments,which has flame resistance requirements or not,or other applications.

Switch cubicle special-purpose FR4 epoxy sheet
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.
