The arrester of the tubular type is of the protection gap type and is mostly used for lightning protection in the power supply line.
The valve arrester consists of a spark gap and a valve chip resistor. The material of the valve chip resistor is a special silicon carbide. When there is a lightning overvoltage, the spark gap is broken down, the resistance of the valve chip decreases, and the lightning current is brought into the earth. This protects the electrical equipment from lightning currents. Under normal circumstances, the spark gap will not break down and the resistance of the valve rises, preventing the normal AC current from passing through.
Zinc Oxide Arrester is a lightning protection device with excellent protection performance, resistance to contamination, light weight, and stable performance of the valve. The FY1-10 Zinc Oxide Arrester can not only be used for lightning overvoltage protection but also for internal overvoltage protection. FS type 0.22-0.5 kV low voltage valve arrester can be used as lightning overvoltage protection for low voltage AC motors and low voltage distribution equipment. Low-voltage 0.22-0.5MY31 series zinc oxide varistors can be used for over-voltage protection of low-voltage power distribution equipment, and can also be used for internal operation over-voltage protection.
