Electrical Insulator Long Rod 220kv 210kn Suspension Polymer (Composite) Insulator1

    Pillar insulators are important equipment in substations and play an important role in electrical insulation and mechanical support.
In operation, it is necessary to meet the requirements of both electrical insulation performance and mechanical performance. In terms of electrical performance,
Insulators are required to be able to withstand the effects of working voltage, transient operating overvoltage and lightning overvoltage, without serious accidents such as insulation breakdown, flashover, and damage. In terms of mechanical properties, insulators are required to be able to withstand long-term mechanical loads, and at the same time have a good ability to withstand sudden external forces such as hurricanes and earthquakes. At the same time, pillar insulators must also ensure the stability and reliability of work under various harsh weather conditions such as frost, rain and snow, wind and sun, extreme heat and cold.
