3240 (the first 3 represents laminated products, winding products, vacuum pressure impregnating products; The second 2 represents the inorganic sole laminate; The third fourth represents the temperature index of 155 degrees; The fourth represents the product variety code; 3240 fully known as epoxy glass cloth laminate
Common g-10 application fields: motor, transformer, switch cabinet, tooling and fixture, insulation gasket, high voltage switch insulation, transformer insulation gasket and so on.
High-temperature g-11 application field: electric motor with class H insulation resistance grade, transformer, switch cabinet, tooling and fixture, insulation gasket, high voltage switch insulation, transformer insulation gasket and so on.
[appearance] smooth and smooth without impurities.
Color: g-10 light yellow, g-11 dark yellow.
【 characteristics 】
1) high mechanical properties, stable dielectric properties at high temperature and low water absorption rate.
G-10: make a tool shank material.
G - 10: epoxy laminated non-alkali glass fiber cloth, a synthetic material, epoxy filled glass fiber woven with 'E' form, has unusually high strength and wear resistance, and the weight is light, in the high-end folding and straight shank cutter is widely used. It's usually black.
