Composite silicone rubber type (excellent pollution and explosion resistance);
The mainstream models include power station type, line suspension type, and gapless zinc oxide lightning arrester.
Execution standard: Complies with the national standard GB/T 18802.1, and some models are suitable for special environmental requirements such as high altitude and salt spray
Core components: mainly composed of zinc oxide valve plates, with excellent nonlinear volt ampere characteristics, response time ≤ 25ns, and current capacity meeting the short-circuit current requirements of 35kV systems ;
Shell material: composite silicone rubber type: lightweight, good weather resistance (-40 ℃~85 ℃)
Lightning protection for 35kV transmission lines and substations to reduce lightning trip rates and equipment insulation breakdown risks;
Power frequency overvoltage suppression (such as frequent operation overvoltage scenarios in wind farms and industrial plants).
Composite shed type should be selected in high-altitude areas, and insulation redundancy design should be added;
Coastal salt spray and chemical pollution areas need to be cleaned with pressure equalization rings or anti fouling flash coatings at least twice a year
