Product Description

FR4 epoxy sheet / HGW2372.1 sheet / EL-GEF sheet / EPGC epoxy sheet / FR4 machined parts

FR4 epoxy sheet are made of woven glass cloth impregnated with epoxy thermosetting resin,laminated under high temperature and high pressure ,the woven glass cloth shall be alkali-free and treated by silane couple


FR4 epoxy sheet,producer as per IEC60893-3-2,These sheets have excellent 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 excellent flame retardant property.the sheets also passed the toxic and hazadous substance detection(RoHS Report)


used as the insulating structure parts in class B-h electric motors,electric equipments,which has flame resistance requirements or not,or other applications.

Bus-bar (also spelled bus bar, or sometimes as buss bar or bussbar, with the term bus being a contraction of the Latin omnibus, "for all") is a metallic strip or bar (typically copper, brass or aluminium) that conducts electricity within a switchboard, distribution board, substation, battery bank, or other electrical apparatus. Its main purpose is to conduct a substantial current of electricity, and not to function as a structural member. Busbars may or may not be enclosed in a bus duct. Also, busbars are important components in electrical power grid because they can reduce the power loss via reducing the corona effects. This is because busbars have bigger surface areas compared to wires.It is the “highway” of power distribution is easier to be designed,quicker to be has repeated electrical performance,low impedance,high anti-interference,and save space.


Bus-bar is used extensively in electric and hybrid traction system,electric traction equipment,Cellular communication,base station,Telephone exchange system,Large network equipment,large-scale computer and medium-scale computer,Power switch system,soldering system,The electric power equipment conversion module and so on.


Bus-bar are divided into :Resin glue type, Edge open type,Edge closed type,Resin sealing type according to the structures.The main composition are Surface insulating material,copper bar,interlayer insulating material,bottom insulating material.

GPO-3 Red /white Grinded Sheet are special material used as Surface insulating material,interlayer insulating material,bottom insulating material which are stable and high-precision.
