Outdoor Isolation Switch

Sangao durable outdoor isolation switch is a complete set of distribution equipment suitable for 3.6-12kV, three-phase AC 50Hz, single busbar and single busbar segmented systems. Mainly used for power transmission of small and medium-sized generators in power plants; The power distribution and transmission of substations in factories, mines, and enterprises' power systems; And the starting of large high-voltage motors, and the control, protection, and monitoring of the system.

The outdoor isolation switch extracts the essence of the company's valuable experience in switchgear design and manufacturing, and combines advanced processing equipment to produce and develop a new generation of intelligent low-voltage switchgear.

The structural design can meet the requirements of various entry and exit methods: up and down, up and down, and up and down.

Compact design: can accommodate more functional units in a smaller space.

Strong structural versatility and flexible assembly: 25mm C-shaped profiles can meet the requirements of various structural forms and pull-out units in any combination, protection level, and usage environment.

Standard module design: It can form standard units for protection, operation, conversion, control, adjustment, indication, etc. Users can choose according to their assembly needs.

The busbar is protected by high-strength flame-retardant and high insulation strength plastic functional boards, which have anti fault arc performance, ensuring safe and reliable operation and maintenance.

The cabinet has passed multiple tests including 3C certification, internal arc test, seismic test, high-altitude test, salt spray test, aging test, etc.

Structural characteristics

Thick specification aluminum zinc alloy steel shell (thickness ≥ 2.5mm), with a sealing level of IP4X, and a corrosion resistance 40% higher than galvanized steel.

The reinforced frame can withstand 8 levels of vibration and complies with the IEC 62271-3 standard, thereby saving structural renovation costs.

Independent functional areas: Four independent functional areas (distribution/wiring/control/cables), equipped with 2.5mm thick steel isolation plates to prevent cross compartment fault propagation.

Molded SMC composite isolation plate (dielectric strength 15kV/mm) eliminates the risk of partial discharge.

Integrated testing port, which can be monitored in real-time through external instruments.

Application

Substation feeder control and busbar segmentation.

Steel plants, chemical parks, mining operations.

Data centers, hospitals, airports (primary power distribution system).

Photovoltaic power station, wind farm boosting substation.
