60mm GPO3 Fiberglass Products With 180 Seconds Arc Resistance

GPO3(UPGM203) with properties of CTI600&Arc 180 seconds , thickness from 0.5mm to 60mm


GPO-3 material was made of polyester resin , glass fiber mat and aluminium hydroxide , the material inclusive laminated sheet , pultrusion profiles and molded parts .


HC is one of the biggest GPO3 manufacturer in China and the drafter of standard for this material in China , the material has been certified by UL/ROHS/REACH/EN45545/glowing filament and other certification from the third party .


GPO-3 laminated sheet , pultrusion profiles and molded parts can be machined by CNC/milling machines/punching machines and etc., it means that the materials with very excellent machining properties .


For the temperature index , It is the F class material which required continuous operating time meet to 20K hours .

This material machined parts with very nice arc property , it was application to every kinds of electrical equipment which has arc when running , it will remove the arc . In other way the machining precision can meet ISO2768-F according to the customer demand .It is so high precision in insulation industry . As soon as we know , higher precision which we can meet , better for the electrical products .

Feature of GPO-3

It can be machined into precision tolerance part by CNC, it can meet tolerance ISO2768-F class

It has very good arc property when running in every electrical equipment ;

If the thickness of parts less than 2mm , it can be punched by punching machine and will save machining cost .

It is green product , halogen free of the material , meet requirements of RoHs and Reach .

This material is widely used in every low and medium voltage electrical .

It has nice properties of Arc resistance , it meets more than 180s when operation .

Application of GPO-3 material

GPO-3 laminated sheet with the performance on electrical properties such as arc resistance when it is operating in electrical equipments . It has advantage of low smoke , it means the material can be used in railway traffic equipments . As far as I know , the materials have been using in metro located in Xiamen city/Xi’an city of China . As we known , Our GPO-3 materials have been used in high speech train due to low smoke and nice properties of electrical . So many electrical products have the arc while it is running . Arc will callused the insulation materials carbonized . If the material carbonized, it will be become semiconductor , so the properties will be effected .
