Light green EPGC202 epoxy sheet / EPGC202 sheet with No-halogen
Light green EPGC202 epoxy sheet are 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
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:EPGC202 sheets used as the insulating structure parts in class B-h electric motors,electric equipments,which has flame resistance requirements or not,or other applications.

Electric reactor is also called inducer. When the conductor is charged with electricity will creates a magnetic field within a certain space.so all the conductor exist different inductive level.But the inductive level of straight long conductor is low,The magnetic field is not strong.So Electric reactor’s wire are wound into a solenoid which is called air-core reactor.Sometimes in case to raise the inductive lever of solenoid,the solenoid is inserted with iron core.it is called iron core reactor.
According to the structure and cooling medium,electric reactor are divided into QKSGK,Dry iron core reactor,CKSJ,Oil immersed hollow reactor,The clamping type dry reactor,Winding type dry type air core reactor,Cement reactor.
GPO-3 sheet ,FR-4 sheet is mainly used as base and cover plate,air gap plate of electric reactor
