GPO-3 Insulation Sheet: Ideal Choice for Electrical Insulation

In the field of electrical insulation materials, GPO-3 insulation sheet has emerged as a high – performance product. As a key product of Youda Insulation Materials Co., Ltd., it is attracting more and more attention from B – end wholesalers with its excellent performance and outstanding advantages.

Product Introduction

GPO-3 insulation sheet is a composite material made from fiberglass – reinforced unsaturated polyester resin. It has a series of excellent properties, such as high – grade electrical insulation, good mechanical strength, outstanding heat resistance and flame retardancy. With a flame – retardant grade of UL 94 V – 0 and a dielectric strength of ≥10 kV/mm, it can meet the strict requirements of various electrical equipment for insulation materials.

Application Scenarios and Advantages

Low – voltage Electrical Equipment: GPO-3 insulation sheet is widely used in low – voltage electrical equipment, such as insulating supports, barriers, cable partitions, and motor end covers. Its high dielectric strength and arc resistance make it an ideal choice for key insulation components, which can effectively prevent electrical breakdown and arc – related faults, ensuring the safe operation of equipment. For example, in circuit breakers, it can be used as safety baffles and phase – separation plates, playing a crucial role in arc suppression and insulation.

Medium – voltage Switchgear: In medium – voltage switchgear, GPO-3 insulation sheet also shows its unique advantages. It can be used as busbar supports and spacers, with strong tensile and flexural strength, which can bear the weight and mechanical stress of busbars, while maintaining excellent electrical insulation. Moreover, its outstanding heat resistance allows it to operate reliably in the temperature range of – 50°C to + 155°C, ensuring the stable operation of switchgear in different environmental conditions.

Transformers: In transformers, GPO-3 insulation sheet is used for structural insulation parts. Its good chemical and moisture resistance can prevent the influence of oil, moisture and other substances, ensuring the long – term stable operation of transformers. At the same time, its good machinability enables it to be precisely processed into various shapes according to the needs of transformers, such as ventilation heat – dissipation rods and core – coil insulation parts.
