Composite pin insulators are mainly used in overhead transmission lines and distribution lines to support conductors and maintain electrical insulation between conductors and towers. Its product applications can be summarized as follows:

1. The insulation and support of overhead transmission lines are used in high-voltage and ultra high voltage transmission lines to fix the wires and provide reliable electrical insulation, ensuring the safe operation of the lines.

2. Distribution line insulation is widely used in 10kV, 35kV and other distribution lines to support wires on poles and prevent leakage and short circuits.

3. The insulation of substation equipment is used to provide insulation support for busbars, equipment leads, and other parts inside the substation, improving the safety of equipment operation.

4. Due to their light weight and good pollution resistance, urban and rural power grid renovation projects are commonly used for upgrading and improving the reliability and anti pollution flashover ability of the lines.

5. The operation of power lines in harsh environments is suitable for heavily polluted environments such as coastal areas, chemical zones, mining areas, and humid and foggy areas, and has excellent anti pollution flashover performance.

6. Compared with traditional porcelain insulators, composite needle insulators have the advantages of light weight, low breakage, easy installation, and good impact resistance. They have gradually replaced porcelain products in many occasions.
