Insulated Switchgear – SF6

Insulated Switchgear – SF6 is a type of gas-insulated switchgear with a compact modular design, meeting the requirements of all types of substation switchgear, cable branch boxes, and switchgear-type substations. It features a compact structure, safety, high reliability, and long service life, especially requiring no maintenance.

Main Functions of Insulated Switchgear – SF6:

1. Circuit Interruption: Opens or closes electrical circuits in substations or electrical networks
2. Overload Protection: Protects the system from electrical overload conditions
3. Switching: Allows switching between different power sources within the system

Advantages:

• Compact Size: Saves installation space compared to traditional equipment
• Good Protection: Resistant to moisture, dust, and environmental factors, extending the service life of the equipment. The frame and outer shell are made of stainless steel, enhancing durability and resistance to corrosion
• High Performance: Improved operational performance with high reliability
• Safety: Uses insulated plastic components to prevent electrical leakage and ensure safety for operators. Additionally, the SF6 (sulfur hexafluoride) gas in the switchgear provides insulation and minimizes the risk of electrical arcing
• Easy Maintenance: The equipment is typically designed for easy access, making maintenance and inspection straightforward

Environmental Conditions:

• Altitude: ≤ 5000 m
• Ambient Temperature: Maximum temperature 50°C, minimum temperature -25°C. The average value over 24 hours should be less than 35°C
• Ambient Humidity: The average relative humidity over 24 hours should be ≤ 95%, and the monthly average relative humidity should be ≤ 90%
• Installation Environment: No explosive gases or corrosive gases in the surrounding air. The installation site should be free from strong vibrations or impacts
