Product Description


Product Introduction

GPO-3 laminated sheet is the insulation sheet with excellent arc resistance which was made of fiberglass and polyester resin , the fiberglass was impregnated in polyester resin with the aluminium hydroxide material and then press under the high temperature & pressure by machines . As we known , high voltage will generate the arc , but arc will be generated when switchgear is in operating , if the property of arc resistance is not good enough , arc will break down the insulation sheet , it caused the electric equipment damaged , it is very huge lose for the whole project . The reason of arc resistance is GPO-3 will generated gas and gas will eliminate the arc . So , the arc resistant property is very important in the electric equipment . Due to mentioned property and other properties , more and more electric equipment manufacturers choose GPO-3 as the insulation sheet if it has the arc when equipment running .At present , the GPO-3 material has been exporting to more than 30 countries all over the world , the customers include so many top 500 electrical manufacturers in the world .


Feature of product

1. It is very high mechanical property material and the excellent insulation properties with CTI600

2. This material is excellent Electrical Performance material with the arc resistance more than 180 seconds , it can reach to 184 seconds.

3. It is the green product and recognized by latest revision RoHs and Reach.

4. It is the customized product which can be machined as per client’s drawings .

5. It has very excellent on low and high working temperature , the temperature index of this materials is from -270 to 155 degree centigrade , it can adjust to very low and high temperature when running.

6. It has the advantages on low smoke material and halogen free which will save the lives when breaking out of fire;


Application of material

GPO-3 laminated sheet and machined parts are application to Switch cabinet in rail traffic , such as metro , CRH train , high speed rail etc. most of them are used as the insulation sheet , insulation support and cover plates in switches , because it has very excellent properties on electrical and mechanical . The most important is good arc performance , further more the materials with the advantages with low smoke , non-poisonous , halogen free and good fire resistance with EN45545 certificate .

As we know , it is very important to rail traffic of the safety , Railway traffic is a highly intensive place for people , arc performance is very very important , is the arc is not good enough , the material will be break down by the arc , it will cause the fire hazard . In other way , the low smoke , non-poisonous and good fire resistance are top important performance to ensure safety running. Actually , most of the train manufacturers in China have already contacted with us to supply this material , we have so rich experiences on it .
