Core components: Zinc oxide valve plate as the main body, excellent nonlinear volt ampere characteristics, response time ≤ 25ns, suitable for system short-circuit current;
Shell material: composite silicone rubber: excellent weather resistance (-40 ℃~+85 ℃), salt spray and ultraviolet resistance, protection level IP65
Auxiliary design: Equipping ring configuration: Optimizing the structure by measuring the potential distribution, reducing the non-uniformity coefficient to ≤ 13.56%
Lightning and operational overvoltage protection for 330kV substation incoming terminals, transformers, and transmission lines, limiting overvoltage to below the equipment's withstand level;
In mountainous and high soil resistivity areas, line-type lightning arresters are used to reduce lightning trip rates by ≥ 30%;
Zinc Oxide Lightning Arrester: equipped with a voltage equalizing ring, excellent pollution resistance, leakage distance ≥ 25mm/kV, suitable for coastal salt spray or industrial pollution areas;
Line type gapless lightning arrester: integrated voltage equalization ring design, maximum potential distribution unevenness coefficient ≤ 13.56%, suitable for lightning protection in mountainous areas and high soil resistivity areas, reducing tripping rate.
Composite jacket type is preferred in coastal salt spray areas, combined with a pressure equalization ring to improve stability
In frequent thunderstorm scenarios, it is recommended to use ceramic-coated lightning arresters in conjunction with tubular lightning arresters to form multi-level protection
