GPO-3 insulation board is also known as GPO-3 laminate. It is a hard plate-shaped insulation material made of alkali-free glass fiber felt board impregnated with unsaturated polyester resin paste and added with corresponding additives through hot pressing. GPO-3 insulation board, also known as UPGM-203, refers to unsaturated polyester glass fiber felt board material, which is used for mechanical and electrical purposes. It has good electrical properties under high humidity, good mechanical properties under medium temperature, flame retardancy, good arc resistance and resistance to leakage traces.

Switchgear is an electrical equipment. The external line of the switchgear first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage room switchgears, high-voltage busbars, such as power plants, etc. Some also have low-frequency load shedding to protect the main equipment. The main function of the switchgear is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and energy conversion in the power system. The components in the switch cabinet mainly include circuit breakers, disconnectors, load switches, operating mechanisms, mutual inductors and various protective devices. The function of the insulation components is to support and isolate, so the insulation materials are required to have high electrical strength, good mechanical properties and arc resistance. These insulation components are generally processed with GPO-3 insulation boards.
