Type classification: 11kV arresters are mainly distribution type and power plant type zinc oxide lightning arresters. Zinc oxide arresters have become mainstream due to their nonlinear current-voltage characteristics and high response speed.
Surge Limiter 11 kV Surge Limiter
Type classification: 11kV arresters are mainly distribution type and power plant type zinc oxide lightning arresters. Zinc oxide arresters have become mainstream due to their nonlinear current-voltage characteristics and high response speed.
Performance standard: Must comply with the national standard GB/T 18802.1, export models are compatible with IEC 60099-4 standard, emphasizing the conformity of rated voltage, residual voltage and other parameters with 11kV system
Main component: Mainly composed of zinc oxide valve plates, achieving fast response through non-linear characteristics.
Shell material: silicone rubber, weather resistance can cover -40℃~85℃, some models use epoxy resin seal to enhance moisture resistance (IP65)
Main functions:
Lightning surge protection for 11 kV distribution lines and substation equipment to reduce the frequency of lightning triggers;
Supply frequency continuous current cut-off is used to protect the insulation of equipment such as transformers and switchgear.
Adaptation environment:
Class III contaminated areas require regular cleaning of the surface from contamination;
It is recommended to use lightning protection clamps or controlled discharge lightning rods in areas with numerous thunderstorms (such as active lightning rods).
