High Voltage And Low Temperature Insulation UPGM203 Sheet

High voltage and low temperature insulation resistance sheet of UPGM203


UPGM203 is also called GPO-3 sheet , it was composited by unsaturated polyester , glass fiber mat and aluminium hydroxide material . It has very nice excellent insulation properties and low temperature resistance performance , more and more electrical equipment products use this material. According to test organization from the third party , the break down voltage can meet 14.3KV/MM , that is means smaller thickness sheet can bear higher voltage , it will decrease thickness , weight and volume for the whole electrical , so the production cost will be saved .

For the temperature resistance , as we know that it is very cold in area of circumpolar latitude or high altitude. The strength of material will reduce if the temperature is low , but our UPGM203 has passed the test by -270℃.

In China , the rail way of Qinghai-Tibet has already have transportation service , as we know the area of Qinghai-Tibet is circumpolar latitude and very low temperature in winter . However , our GPO-3 material has already used in this line and has already running for many years .
