What Are the Different Types of MV Switchgear?

Medium Voltage (MV) Switchgear plays a crucial role in electrical power systems, ensuring safe distribution, control, and protection of circuits operating typically between 3kV and 36kV. Understanding the different types of MV Switchgear helps in selecting the right equipment for industrial, utility, and commercial applications. At Wenzhou Wzonpa Import and Export Co., Ltd., our factory provides a comprehensive range of MV Switchgear designed for reliability, efficiency, and long service life.

1. Air Insulated Switchgear (AIS)

Air Insulated Switchgear uses air as the primary insulating medium. It is commonly used in indoor or outdoor substations due to its simplicity, easy maintenance, and cost-effectiveness. Our factory produces AIS systems with compact design, high performance, and adaptable configurations suitable for diverse installations. AIS systems are preferred where space is not a limitation and environmental factors are manageable.

2. Gas Insulated Switchgear (GIS)

Gas Insulated Switchgear employs SF6 gas for insulation, offering superior protection against environmental contaminants and minimal maintenance requirements. This type is ideal for urban substations and industrial facilities where space is limited. At Wenzhou Wzonpa Import and Export Co., Ltd., we supply GIS solutions with optimized sealing systems, corrosion-resistant housings, and enhanced dielectric performance, making them a reliable choice for demanding environments.

3. Vacuum Switchgear

Vacuum Switchgear is known for its exceptional arc-quenching capability and long service life. The arc formed during operation is extinguished within a vacuum interrupter, which ensures high reliability and low maintenance. Our vacuum Switchgear products are suitable for power distribution networks, ensuring stable operation under heavy load conditions. They are also environmentally friendly as they contain no harmful gases or oil-based insulation materials.

4. Hybrid Switchgear

Hybrid Switchgear combines the benefits of AIS and GIS technologies. It features compactness, high reliability, and reduced footprint while maintaining easy accessibility for maintenance. Our hybrid solutions are tailored to meet specific customer needs, offering superior performance for both new and existing substations. By leveraging our technical expertise, we provide cost-effective systems that enhance grid reliability and operational efficiency.

5. Metal-Enclosed and Metal-Clad Switchgear

These two types differ primarily in their compartmentalization. Metal-clad Switchgear isolates each component within its own grounded metal enclosure, providing maximum safety and protection. Metal-enclosed types, on the other hand, share compartments but still maintain reliable separation. Our factory ensures both types are manufactured following strict quality standards to meet international certifications and safety requirements.
