GPO-3 insulation laminated sheet is made from alkali–free glass mat impregnated with an unsaturated polyester resin, and added  the corresponding additives, and then laminated under high temperature and high pressure.

It has better electrical performance under high humidity, while it has better mechanical performance under moderate temperature. What’s more, it has the advantages of fire resistance, arc resistance and anti-leakage.

It is widely used for circuit breakers, molded case circuit breakers, and motor motors.

It has different colors like white, red brown, gray and etc..

It also has different sizes, 2~100mm, 1000×2000mm, 1220×2440mm.
