The 20kV pin-type composite insulator is a key component widely used in medium voltage transmission and distribution systems. Compared with traditional porcelain insulators, composite insulators are lighter in weight, better in insulation performance, and more suitable for long-term outdoor use under harsh environmental conditions.
This product is made of advanced composite materials and offers excellent pollution resistance and high mechanical strength. It is ideal for substations, distribution lines, and urban/rural electrical grids.
Core Rod: Made of high-strength epoxy fiberglass for superior tensile and bending performance.
Housing: Made of top-grade silicone rubber, with excellent weather resistance and hydrophobicity.
Metal End Fittings: Hot-dip galvanized steel or aluminum alloy for corrosion resistance and firm mechanical connection.

Strong Pollution Resistance: Silicone rubber is hydrophobic, reducing pollution flashover risks.
Lightweight Design: Only one-fourth the weight of porcelain insulators, easier to handle and install.
Excellent Mechanical Strength: Fiberglass core resists high tensile and bending loads.
Durable and UV Resistant: Maintains performance in harsh outdoor conditions for over 10 years.
Eco-Friendly: Non-toxic and complies with green power equipment standards.
