Overhead Line Composite Pin Insulator
Description
Technical Parameters
Gaodian Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of overhead line composite pin insulator in China. With abundant experience, we warmly welcome you to buy advanced overhead line composite pin insulator made in China here from our factory. We also accept customized orders.
25kV Overhead Line Composite Pin Insulator is designed for medium-voltage overhead distribution systems where lightweight construction, contamination resistance, and long service life are required. This type of insulator is widely used in urban and rural distribution networks, industrial power systems, and utility pole installations. Compared with porcelain insulators, polymer ones provide easier transportation, lower maintenance cost, and improved performance in coastal, humid, and polluted environments.

Main Features
Lightweight
Composite insulators are much lighter than porcelain types, making transportation and installation easier.
01
Excellent Pollution Performance
The silicone rubber surface is hydrophobic, meaning it repels water and reduces leakage current under polluted or wet conditions.
02
High Mechanical Strength
The core provides strong resistance to mechanical stress and tension.
03
Low Maintenance
They require less cleaning and maintenance, especially in coastal, industrial, or dusty environments.
