Transformer Reactor EPGC202 epoxy laminated sheet FR4 epoxy glass cloth machined part

Transformer Reactor EPGC202 epoxy laminated sheet is made by alkali-free glass fiber cloth impregnated with high quality epoxy resin and suitable in organic fillers by processing under pressure and heat, it is rigid insulating laminated sheet.


EPGC sheets(thermal class B-H),producer as per IEC60893-3-2,These sheets have Good 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 Good flame retardant property.the sheets also passed the toxic and hazadous substance detection(RoHS Report)


It is mainly used in the insulation structure parts of the electrical equipment,the bottom pad of PCB drilling machine, FPC reinforcing plate,electrical insulation,carbon film board,drilling pad and other PCB testing frames, driling bottom pads ,distribution device wire clips,transformer insulation ,motor gaskets,playing equipments,high performance electronic insulation parts processing.Glass fiber mason, carbon film,precision swam tar wheel,precison test plate,electrical equipment insulation partition board,insulation pad,transformer insulation board,motor insulation,deflection coil terminal board,electronic switch insulation board and so on.

Inverter cabinet are used to convert DC power(Battery,Storage bottle)to AD power( Generally 50Hz 220V sinusoids or square wave),it consist of Inverter bridge,logic control parts,filter circuit.

Inverter Cabinet are divided into:Centralized inverter and String Inverter according to the applicable situation.

Centralized inverter technology is made of couples of parallel PV string connected to DC input of centralized inverter,the larger power use the three phase IGBT power module,the smaller power use the tield effect transistor and DSP conversion controller to improve the quality of electric.make the power output close to the Sine wave current.generally used for large photovoltaic power station (>10kW) system.

String Inverter is base on modularization.each photovoltaic group (1-5Kw) equiped with 1 Inverter,
Has maximum power peak tracking at DC side,Parallel connected at AC side.String Inverter has become the most popular inverter in the international market.

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.
