Standardized zinc oxide lightning arresters are mainly used to limit lightning overvoltage and operational overvoltage, and protect the insulation of power equipment.

Its product applications can be summarized as follows:

1. To prevent lightning overvoltage, installation on transmission lines, substations, and distribution equipment can quickly discharge lightning current and avoid equipment damage caused by lightning overvoltage.  

2. Limiting overvoltage during operation. When the power grid undergoes switch operation, fault disconnection, or other situations, overvoltage can be generated, and lightning arresters can limit it within a safe range.  

3. Insulation protection for power equipment is used to protect equipment such as transformers, circuit breakers, transformers, cables, busbars, etc., extend equipment life, and improve operational reliability.  

4. Suitable for multiple voltage levels and applicable to transmission and distribution systems such as 10kV, 35kV, 110kV, 220kV, 500kV, etc., it is the most commonly used overvoltage protection device in power systems.  

5. The standard configuration of substations and distribution systems is widely used in power plants, substations, switch stations, ring main units, box transformers and other places, and is a standardized equipment for overvoltage protection.  

6. Improving system operation stability has the characteristics of fast response speed, low residual voltage, and strong current carrying capacity, which can effectively reduce lightning strikes and operational accidents and improve power supply reliability.
