Advantages of Ring Switchgear

01/

Compact Design

Space-Saving: RMUs are typically more compact than conventional switchgear, suitable for installations where space is limited.
Integrated Components: RMUs integrate multiple functions (e.g., switching, protection, and monitoring) into a single unit, reducing the footprint.

02/

Reliability and Availability

Improved Reliability: RMUs are designed for high reliability with fewer components, which reduce maintenance needs and longer service life.
Enhanced Availability: The ring configuration allows for alternative supply paths, improving system availability and reducing the likelihood of outages.

03/

Ease Operation

Simplified Switching: The design of RMUs facilitates easier and safer operation, with a clear indication of the operational status.
Remote Control Options: Many RMUs can be equipped with remote control and monitoring capabilities, enhancing operational efficiency.

04/

Flexibility

Modular Design: RMUs can be expanded or modified easily, allowing for flexibility in system design and future upgrades.
Versatile Applications: RMU can be used in various applications, including urban networks, industrial plants, and renewable energy integration.

Types of Ring Switchgear

Outdoor SF6 RMU Inflatable Cabinet
Outdoor SF6 RMU inflatable cabinet is mainly used in 10kV-35kV distribution grids. SF6(sulfur hexafluoride) gas is utilized as the arc-extinguishing and insulating medium. It has a compact structure and occupies a small area.

XGN口-12 Inflatable Ring High Voltage Switchgear
Full sealed and full insulated XGN□-12 Insulated Ring Main Unit high voltage switchgear is a new generation of inflatable ring main unit switchgear which is a composite device encapsulated in a solid metal frame that houses different electrical devices.

GTXGN-12 Solid Insulation Ring Main Unit
GTXGN-12 Solid insulation ring main unit (RMU) is a type of switchgear designed for use in electrical distribution systems. It is characterized by its use of solid insulation material, which offers superior dielectric strength and reliability compared to traditional air-insulated or gas-insulated switchgear.

XGN-12 SF6 Gas Insulated Switchgear
XGN-12 SF6 gas insulated switchgear is a new generation of switch products independently developed by Jinneng with independent intellectual property rights.

XGW-12 Primary and Secondary Fusion Ring Main Unit
It integrates primary equipment (such as circuit breakers, isolating switches) and secondary equipment (such as protective relays, measuring instruments, control devices) into a compact enclosure, realizing functions of power distribution, control, and protection in electrical systems.

Applications of Ring Switchgear

FAQ

Q: What is the difference between switchgear and ring switchgear?

The switchgear is installed indoors, mainly on the feeder line of the substation or the switching station of the line terminal.
The ring main unit is installed on the side of the road of the outdoor street, replacing the opening and closing station in places where there is no way to build a house.

Q: What are the advantages of ring switchgear?

Ring Main Unit is a SF6 insulated compact Switchgear equipped with SF6 Switch disconnector and vacuum circuit breaker.
Saving Time and Cost, it is a complete switchgear and is easy to install, saving installation and commissioning time.

Q: What is the composition of a ring switchgear?

A: Ring switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment.

Q: What is the working principle of ring main unit?

A: It works within a closed-loop electrical distribution system (ring system), ensuring continuous and stable power supply even when faults occur. At its core, the RMU employs a combination of switches, circuit breakers and fuses, meticulously designe and precisely manage electrical faults.

Q: What is a ring switchgear?

A: In a ring network each Ethernet switch is connected to two other switches forming a ring. This provides two benefits: Each switch has a redundant connection (link) into the network.
