composite insulators

Composite insulator is the key equipment in modern power system. It mainly consists of mandrel, umbrella skirt sheath and end fittings. As the main support structure, the mandrel is made of high-strength glass fibre resin, which has excellent mechanical strength and can withstand external forces such as wire tension and wind. The umbrella skirt sheath is made of silicone rubber and other polymer materials, with excellent hydrophobicity, which can effectively prevent dirt flashover and maintain good insulation performance in harsh environments.

Compared with traditional insulators, composite insulators have significant advantages. Its light weight, easy to install and maintain, can significantly reduce construction costs and labour intensity. And excellent pollution resistance, in heavily polluted areas can still run reliably, reduce the number of power outages and maintenance, to protect the stability of power supply. Because of this, composite insulators are widely used in transmission lines, substations and other scenes, whether high-voltage, ultra-high voltage or ultra-high voltage grid, can see its figure, for the safe and stable operation of the power system to provide a solid guarantee.
