QLG type SF6 gas insulated ring main unit
QLG type SF6 gas insulated ring main unit
QLG type SF6 insulated metal-enclosed switchgear is a switchgear developed and produced by our company. This equipment uses SF6 gas as the insulating medium for the switch, with load switches, vacuum circuit breakers, and live busbars all sealed in a closed stainless steel container filled with a certain pressure. The external part uses American/European standard bushings to connect with incoming and outgoing cables through cable joints, forming a fully insulated and fully sealed structure, effectively waterproof and dirt-resistant, suitable for various harsh environments. It is widely used in 12kV ring network or terminal power supply systems.

Product Overview and Features
Product Overview
The QLG series ring main unit is independently developed and produced by our company, featuring SF6 gas insulated metal enclosed switchgear. This equipment uses SF6 gas as the insulation and interruption medium, with load switches, vacuum circuit breakers, and live busbars all sealed within a stainless steel container filled with gas at a certain pressure. The exterior uses American/European standard type bushings connected to incoming and outgoing cables through cable joints, forming a fully insulated and fully enclosed structure, effectively flood-proof and dirt-resistant, suitable for various harsh environments. It is widely used in 12kV ring network or terminal power supply systems.
Product Features
1. Maintenance-free
SF6Gas overall common box structure, dynamic and static contacts, arc extinguishing chamber, and busbars are sealed in the same gas chamber. Designed for a maintenance-free lifespan of 30 years.
2.Reliable Mechanical Interlock
Equipped with various reliable mechanical interlocks, and the cabinet panel has simulation markings to ensure operational safety.
3.Fully Sealed, Fully Insulated Cable Inlet and Outlet
According to user requirements, corresponding fully sealed and fully insulated cable heads are used for connection. It also has a live display function, which can accurately show the live status of each circuit.
4.Modular and Expandable
Using an expansion module combination method, up to 6 modules can be realized in the same gas chamber, and more can be achieved through busbar expansion. The expansion busbar is fully insulated and fully shielded, ensuring it is unaffected by climatic conditions and maintenance-free.
5.Multiple Wiring Schemes
According to user needs, combinations such as load switch, load switch + fuse protection, or vacuum circuit breaker protection are used to meet the needs of various incoming and outgoing circuit configurations.
6.Visible Breakpoint
Through the observation window on the panel, the load switch breakpoint or grounding switch position can be seen, fully ensuring the safety of personnel and equipment.
7.Electric Operation, FTU
Using a dedicated voltage transformer for power supply, providing power and measurement protection voltage signals for the operating mechanism and FTU. A dedicated battery and charging module are installed to ensure uninterrupted power supply for the operating power and FTU. FTU devices with corresponding functions are provided according to user needs.
