The 220kV, 110kV, and 35kV rod-type suspension composite insulators are widely used in high-voltage transmission lines and substations. These insulators offer excellent electrical insulation and mechanical strength. Manufactured from composite materials, they are lightweight, pollution-resistant, and highly durable - making them a superior alternative to traditional ceramic insulators.
Rod-type composite insulators consist of three main parts: core rod, sheds, and metal end fittings.
Core rod: Made of high-strength epoxy glass fiber, provides mechanical support.
Sheds: Silicone rubber with excellent hydrophobicity, UV resistance, and aging resistance.
Metal fittings: Hot-dip galvanized steel or aluminum alloy for corrosion resistance and conductivity.
