Polymer Pin Insulator – Innovative Development in the Field of Insulators for Power Lines  

A polymer pin insulator is a complex element of electrical equipment that simultaneously supports and insulates overhead power lines. It is made from modern composite materials, which makes it lighter and more reliable than glass or porcelain insulators.  

What is a Polymer Pin Insulator?  

As all polymer pin insulators, they comprise a core rod made of fiberglass reinforced resin with silicone rubber housing around it and metal end fittings. Leading to easy and secure mounting. The design gives these insulators unparalleled strength, durability against harsh weather, and excellent electrical insulation.  

Pin insulators are fixed on poles, and as conductors are attached to them, they function also to prevent current leakage, even during extreme weather or in a highly polluted environment.  

Key Features  

Reduced Weight and Simplicity of Installation: Compared to ceramic insulators, polymer pin insulators are lighter which reduces both installation and handling time.  

Mechanical Strength: The fiberglass core increases the polymer’s insulators strength against bending, tension, and other mechanical forces.  

Greater resistance to Wetting: The silicone rubber cover improves hydrophobic performance by reducing the water surface current aiding flashover performance.  

Exposure to Ultraviolet Rays and Weather Elements: Reliable performance in coastal areas.
