Product Overview
The Polymer Pin Insulator is designed for overhead distribution and transmission systems from low to high voltage applications. It is built with a fiberglass reinforced epoxy core, high-quality HTV silicone rubber housing, and hot-dip galvanized metal fittings.
Compared with traditional porcelain insulators, this product is significantly lighter, mechanically stronger, and offers superior resistance to pollution, UV radiation, and harsh environmental conditions. It is widely used in modern power networks to improve system reliability and reduce maintenance costs.
Product parameters
Excellent Electrical Performance
The silicone rubber surface provides strong hydrophobicity, preventing water film formation and significantly reducing leakage current. This ensures stable insulation performance even in high humidity and polluted environments.
High Mechanical Strength
The fiberglass reinforced core rod provides outstanding tensile and bending strength, ensuring reliable operation under mechanical load, wind pressure, and ice conditions.
Lightweight & Easy Installation
Compared with porcelain insulators, polymer insulators are much lighter, reducing transportation cost and installation difficulty while improving working efficiency.
Superior Environmental Resistance
Designed for outdoor use, the insulator performs reliably in coastal, desert, industrial, and heavily polluted environments without performance degradation.
