Lightning Arrester
1 Good protection performance: can effectively limit overvoltage and protect electrical equipment from damage.
2 Fast response speed: can respond to overvoltage quickly and discharge energy quickly.
3 Strong current capacity: can withstand large current shocks.
4 High reliability: simple structure, easy maintenance and long service life.
5 Gapless structure: there is no discharge gap, which avoids the protection failure problem of traditional lightning arresters caused by discharge gap failure.

How to understand lightning arrester
Hydrogen oxide arrester, also known as zinc oxide arrester, is a protective device used to protect power systems and electrical equipment from lightning overvoltage and operating overvoltage. It is mainly composed of zinc oxide resistor, insulating bracket, sealing gasket, pressure release device, etc., and is generally filled with nitrogen or SF6 gas.
Zinc oxide arrester utilizes the good nonlinear volt-ampere characteristics of zinc oxide. Under normal operating voltage, the current flowing through the arrester is extremely small (microampere or milliampere level); when it is subjected to overvoltage, the resistance will drop sharply, thereby discharging the overvoltage energy to achieve the effect of protecting the equipment. Compared with traditional arresters, zinc oxide arresters do not have a discharge gap, but use the nonlinear characteristics of zinc oxide to achieve the function of current discharge and breaking.
How to Install a Lightning Arrester
● Choose location: Install at the incoming line end, easy to inspect and maintain.
● Fix base: Securely install using bolts or welding at the specified location.
● Connect lead: Attach to power line or equipment, ensuring a firm and reliable connection.
● Grounding: Ensure proper grounding to discharge overvoltage, meeting resistance standards.
● Insulation test: Use an insulation tester to ensure good insulation performance.
● Inspect and test: Check installation, perform voltage tests to verify performance.
● Regular maintenance: Clean, check connections, and measure insulation resistance regularly.
