In modern power transmission systems, the stability and performance of insulation devices directly influence the efficiency and safety of power lines. The 25kV rod-type composite insulator, commonly used in medium voltage lines, is gaining popularity due to its compact design, high insulation strength, and excellent pollution resistance.
The 25kV rod-type composite insulator is a suspension-type insulator made from advanced composite materials. It is designed for use in overhead transmission lines and substations at the 25kV voltage level. Compared to traditional porcelain insulators, it offers lighter weight, higher mechanical strength, and improved pollution flashover resistance.
The insulator consists of three main parts:
Core Rod: Made of epoxy resin reinforced fiberglass (FRP) for superior tensile strength and fatigue resistance.
Housing: Made of high-temperature vulcanized silicone rubber, featuring excellent hydrophobicity, self-cleaning, and aging resistance.
Metal Fittings: Hot-dip galvanized steel ends crimped securely to the core rod for long-term mechanical reliability.
