Product Description
The 33kV Composite Pin Insulator is a high-performance insulation component engineered for medium-voltage overhead distribution lines, designed to replace traditional porcelain pin insulators with superior durability and environmental adaptability. Crafted from a glass fiber reinforced polymer (GFRP) core and high-quality silicone rubber housing, it integrates exceptional mechanical strength, reliable electrical insulation, and excellent anti-pollution performance.
Compliant with IEC 60168, IEC 60383, and GB/T 20641 international standards, this insulator is specifically optimized for 33kV power grid applications. Its compact pin-type structure enables direct mounting on wooden, concrete, or steel cross-arms, providing a secure insulation and support solution for overhead conductors in diverse operating environments.
