The composite insulator is an essential component in high voltage power transmission systems. It consists of a durable glass fiber epoxy core rod, high-performance silicone rubber umbrella skirt, and robust metal fittings. This combination provides superior mechanical and electrical properties compared to traditional porcelain insulators.
Our composite insulators are manufactured using premium materials including forged-steel and casting-steel with hot-dip galvanization (HDG) for enhanced corrosion resistance. The production process follows strict quality control measures including drawing, mold making, smelting, casting, annealing, galvanizing, machining, and thorough inspection.
The composite insulators are designed to meet various international standards including IEC, ANSI, and BS specifications. They are suitable for applications ranging from 120kV to 132kV systems and can be customized according to specific project requirements.
Key advantages of our composite insulators include excellent pollution resistance, lightweight construction, high mechanical strength, and long service life. The silicone rubber housing provides superior hydrophobicity and resistance to UV radiation, making them ideal for outdoor applications in various climate conditions.
