Lightning arresters (also known as surge arresters) are essential protective devices in power systems, designed to limit overvoltage caused by lightning strikes or switching operations and discharge surge currents to the ground. They protect transformers, switchgears, cables, and other electrical equipment from insulation breakdown and damage by diverting harmful surges safely, while maintaining normal system operation under standard voltage.

Frequently Asked Questions

What is the primary function of a lightning arrester?

Lightning arresters (surge arresters) limit overvoltage caused by lightning strikes or system switching operations. They protect valuable electrical equipment like transformers, switchgears, and cables from insulation damage by safely discharging the surge currents to the ground.

What voltage levels do these products support?

The standard product configurations support voltage levels ranging from 0.5kV up to 220kV, covering various requirements for power transmission and substation installations.

Can these surge arresters be operated in extreme temperature environments?

Yes. While the standard operating temperature range is -40°C to +40°C, customized models designed specifically for extreme high-temperature or low-temperature areas can be manufactured.

Are these lightning arresters suitable for DC systems?

These arresters are optimized for AC power systems with rated frequencies of 48 Hz to 62 Hz. They are not suitable for DC systems unless explicitly designed and customized.

How should the surge arresters be installed?

They are suitable for indoor or outdoor pole mounting, substations, and switchgear. They are typically installed vertically, but horizontal installation configurations are available upon request.

Is product customization supported?

Yes, customization is supported according to the specific technical requirements, dimensions, or operating environment parameters of the client's project.
