F - Class FR4 With High Compressive and Flexural properties/ EPGC201 Hight Physical porperty machined part
Product Description:
F - Class Epoxy Fiberglass 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
Application:
1. High-voltage motor and electrical equipment as insulating structure: high-tension switch cubible,transformer,frequency changer,Converter,DC motor,AC contactor
2. Switch cubicle:bursting disk,lining plate,arc extinguishing chamber,arcing cylinder,arcing piece,flash barrier,wiring board,terminal plat insulating supports
3. Strut member and bus bar supports
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)
