product description

Description of G11 


G11 high temperature epoxy resin fiberglass board is created by compressing fiberglass cloth, soaked in high temperature resistant epoxy resin under heat with excellent mechanical and dielectric properties, good mechanical performance at high temperature and high humidity condition, and good processability. The insulation class is H class, and the main color is yellow.
Application of G11 

It can be used as insulating structural parts with heat resistance for electrical equipments such as circuit breakers, switch gear, transformers, DC motors, AC contactors, explosion-proof electrical appliances, electric furnace, electric melting furnace, etc. It can also be used for making structural support parts of switch and transformer, bus clamp plate, signal plate, partitions and lining plates of various switch gears, terminal plate, interphase insulation, bottom baffle, contact support parts, movable cover, slot wedge stator, fixed gasket, thin gasket, carbon brush, etc.

Thickness:0.5~50mm   Specification:1020×1220mm;1020×2040mm;1220×2470mm

Advantage of G11 

G11 high temperature epoxy resin fiberglass board produced by ZTelec Group has a low water absorption(almost zero), and its water absorption is only 0.09% after immersion for 24 hours. Its thermal resistant class reaches 180℃ and it can be operated normally in a long period of time at 180℃. It also has a strong mechanical processing performance and can be processed by compressing and cutting according to customer’s demands, meanwhile stable property, beautiful appearance and wide applications.
