GPO-3 fiberglass Sheet Specified for Bus-bar / upgm203 Specified for laminated Bus-bar
Product Introduction:
GPO-3 fiberglass Sheet Specified for Bus-bar is rigid laminated sheet made of heat pressing which composed of e-class glass-mat reinforced unsaturated polyester and inorganic filler binder.
Features:
Electrical Insulation :All grades of GPO3 sheet have inherently good dielectrics. They are engineered to maximize the specific properties required for a wide range of electrical applications.
Flame Resistance :GPO3 sheet are UL-rated V-0. They belongs to halogen-free system that generates very low smoke and smoke toxicity in a fire situation.
Mechanical Strength :Our GPO3 sheet have stable mechanical strength wich won’t cracked when machining
Heat Resistance:Our GPO3 sheet have excellent property retention and dimensional stability at elevated temperatures. These laminates have UL temperature index ratings over 150℃
Application:
GPO-3 fiberglass Sheet are widely used in high-voltage appliance insulators, bus bar supports, and barriers and mounting panels in switch gear, as well as other types of electrical applications.

Description: | 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 system.it is easier to be designed,quicker to be installed.it 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.
