product overview

3-6kV composite jacket lightning arrester? It is a lightning arrester that uses polymer materials as the outer shell, combined with the nonlinear resistance characteristics of metal zinc oxide valve plates, and has excellent electrical insulation performance, high dielectric strength, and good weather resistance. This type of lightning arrester is commonly used in power generation, transmission, transformation, and distribution systems to protect electrical equipment from damage caused by overvoltage.

Working principle

The working principle of the 3-6 kV composite jacket lightning arrester is based on the nonlinear resistance characteristics of the metal zinc oxide valve plate. At normal operating voltage, the valve plate exhibits a high resistance state and the current is almost zero; When the system experiences overvoltage, the valve resistance rapidly decreases, releasing a large amount of current, thereby limiting the system voltage within a safe range?. This design enables the lightning arrester to quickly operate when overvoltage occurs, protecting the system from damage.

Structural characteristics

The composite jacket is made of high molecular polymer material, which has good insulation performance, weather resistance, and mechanical strength, and can effectively protect the internal metal zinc oxide valve plate. In addition, the design of the composite jacket makes the lightning arrester more lightweight, easy to install and maintain.

Application scenarios

3-6kV composite jacket lightning arresters are widely used in power systems such as power plants, substations, and transmission lines, especially in areas with frequent lightning strikes, where their role is particularly important. With the continuous development of the power system and the improvement of intelligence level, the performance requirements for lightning arresters are also increasing. Composite jacket lightning arresters play an indispensable role in modern power systems due to their excellent performance and reliability.
