Excellent Flexural Strength FR4 epoxy sheet / EPGC202 sheet with high performance mechanical properties
Product Introduction:
Excellent Flexural Strength FR4 epoxy sheet is a rigid insulating lamination sheet made of composed imported alkali-free glass fiber cloth ,impregnated with imported high quality epoxy resin,added the imported fire retardant and cementing compound,it is a rigid plate-like insulating material under high temperature and high pressure.
Excellent Flexural Strength FR4 epoxy sheet are widely used in every kinds of switch cubicle such as burshing disk,arc extinguishing chamber ,arcing cylinger,arcing piece,flash barrier,wiring board,terminal plate insulating support;stru parts and bus-bar supports in switchear & transformer, the armature parts of electrical machine such as cover plate,slote wedge,stator ,gasket,shims,carbon brush etc,the epoxy glass laminated sheet series are used much more extensively in consumer electronics.panels display and photovotaic in recent years.

Excellent Flexural Strength FR4 epoxy sheet used in Photovoltaic system
Photovoltaic system consists of main parts of photovoltaic modules, combiner box , inverter cabinets, distribution cabinets, transformers, power grid ,which in addition to transformer and power transmission and distribution are introduced. for the convergence of inverter cabinet/power distribution cabinet/combiner box are very close to the requirement of switch cabinet,HC-GPO3/HC-FR4/HC-GPO3 shapes are used to support,bearing,isolation.The insulation material can be used in the photovoltaic module for pv backboard, and has a strong weather resistance requirement for the backplane ,our research and development team have done a lot of research on it.
Our product is mainly used as Dc cabinet support glass fiber Angle, Reactor output copper bar fixed Angle, AC output fixed Angle, left AC cabinet insulating board 1,right AC cabinet insulating board ,AC contactor fixed barrier, epoxy spacer of sensor , epoxy sealing plate of Busbar, glass fiber for module supporting ,epoxy output board for filter, epoxy cover for module output, epoxy front air flue board, glass fiber module cover ,side glass fiber angle of module, insulating board, Copper platoon fixed plate for output module, sub plate of the fuse installation plate, insulation fender board, guard faceplate, epoxy board for filter output 2, the circular copper platoon stents , magnet ring support board, Fuse partition , Open copper platoon shield , DC cabinet threading plate.
