Impact Resistant CTI 600 GPO 3 Sheet For Railway

GPO-3 sheet with UL/EN45545/ROHS/REACH and with nice property of machining


GPO-3 sheet is the insulation material which was made by unsaturated polyester resin , glass fiber and aluminium hydroxide .

Functions of unsaturated polyester resin is electrical properties such as CTI/Arc resistance /break down voltage and etc.,

functions of glass fiber is mechanical properties such as bending strength , compress strength , tensile strength and etc., function of aluminium hydroxide is filling material and fire resistance.

The glass fiber is the alkali-free glass fiber mat , it will be more save and more environmentally friendly . The GPO-3 from our factory has certificate by UL/ROHS/REACH and EN45545 , all of these certificates will be needed when materials exporting to Europe and North America . For the property of machining , the material can be cut , drill the holes and process on CNC machines .

Application of GPO-3 material 


So far , GPO-3 material has been used in every industries of electrical , but the major industries are PTD , New energy and Railway.

PTD means power transmission and distribution including transformer , Switch cabinet , breaker and etc.,GPO-3 material as the insulation sheet , supporting structure , air gap , top cover and bottom cover in switch and transformer .

New energy include new energy automobile , wind power generation and photovoltaic power generation , GPO-3 material is widely used in these products as the insulation between phases , battery cover plate and insulating sheet in inverter .

Railway requested certificate EN45545 , low smoke , UL94-V0 and non-toxic , the GPO-3 from our factory meet mentioned requirements . We are one of the biggest GPO-3 manufacturer in China , materials have been exporting to more than 30 countries all over the world , the customers including so many companies on top 500 in the world .
