SSR-12 Environmentally Friendly Gas Insulated Ring Network Switchgear
The SSR-12 environmentally friendly gas-insulated ring panel does not run the risk of insulation failure as SF6 switches do when the air pressure gradually decreases at low temperatures.
The greenhouse effect gas SF6 is canceled, and all materials are non-toxic and harmless environmental protection materials.
· SSR-12 environmental protection gas insulated ring network cabinet is a digital ring network cabinet with environmental protection materials, full insulation, full airtight, economical price and convenient operation.
· All the conductive parts in the switch are installed in a sealed stainless steel gas box, and the dry air is used as the insulating body in the gas box; the main switch adopts vacuum arc extinguishing, and the isolating switch adopts a three-station structure.
· The adjacent cabinets are connected by solid insulated busbars.
· The secondary circuit adopts integrated control technology and supports data transmission function.。
Top and bottom isolated symmetrical design
The upper isolation and the lower isolation adopt a symmetrical design scheme, and all parts required for the operating mechanism and switch are common, which shortens the manufacturing cycle and facilitates quality management. Adjacent cabinets are connected by side expansion/top expansion.
Cable Warehouse
- The cable compartment can only be opened if the feeder has been isolated or grounded.
- The bushing complies with DIN EN 50181, M16 bolt connection.
- The lightning arrester can be attached to the back of the T-cable head.
- The one-piece CT is located on the side of the bushing for Easy installation of the cable and is not affected by external forces.
- The height from the casing installation to the ground is Greater than 650 mm.
Pressure relief channel
If an internal arc fault occurs, the special pressure relief device installed in the lower part of the cabinet will automatically open for pressure relief.
Isolation mechanism

Three-station isolation mechanism
The isolating switch adopts a three-position design to prevent misoperation. The high-performance disc spring ensures the stability of the contact pressure and is conducive to the design of the contact shape of the closing shape, thereby ensuring the reliability of the grounding and closing.
The customer only needs to install the core unit module in the cabinet as a set.
We provide customers with a full range of free cabinet drawings, secondary schematic drawings, product manuals, promotional materials, technical advice and other services.
The core unit module can be sold separately to the public, and all parameters have been adjusted in place before leaving the factory, so customers do not need to debug again.
① The analog busbar is clear and easy to operate.
② The main switch is made of alloy button, easy to operate and avoid aging.
③ The grounding switch is equipped with a "voltage blocking device" to prevent the grounding switch from being closed by mistake with electricity.
④ The isolation and grounding switches have two separate operation holes to avoid misoperation.
⑤ Operation hole with anti-misoperation cover and pad lockable.
⑥ Wide angle lens with its own illumination system for easy observation of the isolation break.
