Our company has independently developed and manufactured the WXsafe series of inflatable SF₆- filled metal-enclosed fully insulated ring main unit switchgear. Having passed the type test conducted by the National High-Voltage Electrical Equipment Test Center, these units are widely deployed in 24 kV/10 kV power distribution systems and serve as the preferred switching solution for power transformation and distribution systems across various types of urban and rural users.

Switchgear cabinets adopt a modular unit configuration that can be configured according to different application requirements; they are categorized into two main types: fixed-unit configurations and scalable-unit configurations, thereby meeting the diverse needs of various substations for flexible deployment of compact switchgear.

The WXsafe pneumatic switchgear is a fully sealed system in which all live components and switches are enclosed within a stainless steel enclosure. The entire switching unit is not affected by external environmental conditions, thereby ensuring operational reliability and personnel safety, while also enabling maintenance-free operation. By selecting scalable busbars, any configuration can be achieved, resulting in full modularity. The safety insulation and shielding of the scalable busbars ensure high reliability and safety.

The WXsafe pneumatic switchgear can also provide TV-style automation solutions, thereby establishing the concept of intelligent switching and minimizing the field installation and commissioning workload.

The WXsafe pneumatic switchgear is available in both non-expandable standard configurations and expandable standard configurations. Due to its capability for combining full modules with half-modules and its inherent scalability, it offers flexible configuration options and ease of assembly.

The WXsafe inflatable switch complies with GB standards.

The design service life under indoor conditions (20°C) exceeds 30 years.

Key Product Features:

For WXsafe Series Gas-Insulated Switchgear, SF₆ Gas Serves as Both an Arc-Extinguishing Agent and an Insulation Medium.

The switchgear features a fully sealed and fully insulated structure; the busbars, switches, and live components are completely enclosed within a stainless steel housing, with the interior chamber filled with 1.4 bar of SF6 gas, achieving an IP67 protection rating. The entire switchgear assembly is entirely unaffected by external environmental conditions, ensuring normal operation even under extreme conditions such as shortterm submersion in water. The product requires no maintenance throughout its entire service life. The switchgear is equipped with a comprehensive "Five-Prevention" interlocking system, which completely eliminates the possibility of personnel or equipment operational failures caused by human error.

All switchgear units are equipped with reliable safety pressure relief channels, ensuring the personal safety of operators even under extreme conditions.

Switchgear cabinets are categorized into two types: fixed unit assemblies and scalable unit assemblies. A switchgear cabinet typically features front-mounted incoming and outgoing lines; however, depending on the installation location, it may also incorporate side-outlines or side extensions. The cabinet dimensions facilitate easy installation and are well-suited for applications in confined spaces or under adverse environmental conditions. Depending on the specific requirements of the user, switchgear cabinets can be configured with electric control, remote control, and monitoring devices.
