Description：
A grounding switch refers to a mechanical earthing device that releases the electrostatic charge of the equipment to be repaired and the circuit, ensuring the personal safety of maintenance personnel during power failure. It can withstand a certain period of time under abnormal conditions such as a short circuit but does not pass through the load current under normal conditions. It is usually part of the disconnector.
Industry applications：
It is suitable for power systems with AC 50Hz of 12kV and below. It can be used for grounding protection during the maintenance of high-voltage electrical equipment and can also be used with various types of high-voltage switchgear.
Features：
Ambient temperature: -15°C~+40°C.
Altitude: 1000m and below.
Relative humidity: daily average not more than 95%, monthly average not more than 90%.
The daily average value of water vapor pressure is not more than 2.2 kPa.
The monthly average water vapor pressure is not more than 1.8 kPa.
There is no fire, explosion hazard, serious pollution, chemical corrosion, and severe vibration.
Our company has developed products suitable for high altitude (E≥230mm, altitude up to 4000m) for users to choose.

What are the structural characteristics of indoor high-voltage AC grounding switch？
Contact System：
Materials: The contact system typically uses high-performance conductive materials such as copper alloys to ensure good conductivity and the ability to withstand high current impacts.
Design: The shape of the contacts can vary, including knife-type contacts and finger-type contacts, among others. These designs aim to increase the contact area, reduce contact resistance, and minimize heat generation.
Operating Mechanism：
Manual: Simple and reliable, with lower costs. Suitable for applications where the frequency of operation is low.
Electric: Enables remote control and automated operations, making it easy to integrate with the monitoring systems of substations.
Spring-Operated: Combines the advantages of manual and electric mechanisms. It uses pre-stored spring energy to achieve fast and reliable opening and closing operations.
Insulation Section：
Insulators: Primarily composed of insulators made from materials such as ceramic, glass, or composite materials.
Ceramic Insulators: High mechanical strength and excellent insulation properties.
Glass Insulators: Good self-cleaning performance, capable of resisting windblown sand and dirt to some extent.
Composite Material Insulators: Combine multiple advantages, such as being lightweight and having excellent pollution resistance.
