1230*2100mm GPO3 Polyester Glass Fiber Laminates Sheet

Product Introduction

GPO3 laminate sheet also known as UPGM 203, it is alkali-free fiberglass mat dipped into unsaturated polyester resin adding relevant chemical agent as the basic material pressed under high temperature press into rigid panel as insulating material. This material has good electrical property under high humidity and high mechanical property under medium temperature, it with very nice fire retardant property, good arc resistance and tracking resistance. It's widely used in the low & medium voltage electrical industries such as making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switch-gear and other types of electrical apparatus.

Application

GPO-3 laminate sheet performs well in electrical& mechanical applications that requires high arc , carbon track resistance high strength as well as flame resistance, physical strength, and moderate heat resistance. Grade GPO-3 laminate is used extensively in the making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switch gear and other types of electrical apparatus.

As soon as we know , more and more electrical equipment using this material due to mentioned nice electrical and mechanical properties .
