FAQ
Q: What is the main function of a surge arrester?
A: To divert lightning and switching overvoltage energy safely to the ground, protecting your electrical equipment from damage.
Q: How long do polymer surge arresters last?
A: With proper installation, they typically have a service life of 20+ years.
Q: Can they be used in high-altitude or polluted areas?
A: Yes. We offer extended creepage distance versions for high pollution levels and high-altitude applications.
