Production Introduction:

GPO-3 Grinded sheet with high thickness precision is rigid laminated sheet made of heat pressing which composed of e-class glass-mat reinforced unsaturated polyester and inorganic filler binder.On this basis, the thickness tolerance of the finished product is more accurate.

GPO-3 Grinded sheet with high thickness precision has excellent mechanical strength and automatic processing .It can be used extensively in low & middle voltage electrical equipments as insulating structures such as circuit breaker, switchgear, transformer, DC motor, AC contactor,converter,inverter & explosionproof apparatus etc. ; automotive industry field etc. In electrical Apparatus: making of phase & end barriers, contact terminal supports, terminal plate, insulating supports, bus bar supports and mounting panels in switchgear; arcchute plate, arc extinguishing cover & cylinder in circuit breaker and signal panels in other types of electrical apparatus; and electric melting furnace insulations. In electrical motor: making of armature parts, cover plate,slot wedge, stator, gasket,shims,carbon brush etc.
