Fixed Ring Main Unit

XGN15-12
XGN15SF6 high-voltage ring main unit is a new generation of ring main unit with sulfur hexafluoride load switch as the main switch. The cabinet adopts air insulation, compact and simple structure, flexible operation, easy installation, multiple interlocking functions, and can be widely used in distribution network automation systems with electric mechanism, PT, CT, UPS, FTU, etc. Combined with modern sensor technology and the latest protection and maintenance appliances, it can fully meet the changing needs of the market with its advanced technical performance and light and flexible assembly solutions.
Normal use conditions
★Altitude ≤1000m, (If you have special requirements, please indicate when ordering)
★Ambient temperature: -25℃~+40℃:
★Daily average relative humidity does not exceed 95%:Monthly average relative humidity does not exceed 90%:
★Seismic resistance: 8 degrees.
★No severe vibration and impact, and places with fire, chemical corrosion, explosion hazards
The main switch of the cabinet adopts domestic FLN36-12D/T630-20 or FLN48-120/T630-20 sulfur hexafluoride load switch and ABB's SF6 sulfur hexafluoride load switch or N6's SC6 load switch. According to the different components, it can be divided into XGN15-12 (F) type and XGN15-12 (F, R) type. XGN15-12 (F) type cabinet is equipped with load switch, which is generally used as incoming line. XGN15-12 (F, R) type cabinet is equipped with load switch and current limiting fuse combination. The load switch is responsible for breaking and closing the load current, while the current limiting fuse is responsible for breaking the larger overload current and short-circuit current, which is generally used as outgoing line.
There are two operating modes: manual and electric.
The cabinet body is made of imported aluminum zinc plate processed into a modular structure by CNC machine tools. The protection level reaches IP3X, and it has reliable mechanical interlocking and protection against misoperation functions.
Comply with standards
IEC29B IEG265 IEG129 IEC694 IE0420 IE056 IE0529 IE932

XGN15-12 high-voltage ring network cabinet is a well-designed and excellent performance power equipment, widely used in the power transmission and distribution field of power system.
Sturdy and durable cabinet structure
The cabinet is made of high-quality steel and has excellent mechanical strength and protection performance. Its compact structural design not only saves installation space, but also facilitates transportation and on-site installation. The surface has been specially treated with anti-corrosion, which can operate stably for a long time under harsh environmental conditions.
Advanced insulation technology
The use of advanced insulation materials and insulation structures ensures good insulation performance of the high-voltage part, effectively reduces the risk of leakage and discharge, and improves the operation safety and reliability of the equipment.
Flexible combination mode
According to the actual needs of users, various switchgears, such as load switches, circuit breakers, fuses, etc., can be flexibly configured to meet different power distribution and control requirements. At the same time, it can also realize the connection of multiple circuits to form a ring network power supply, and improve the reliability and flexibility of power supply.
Perfect protection function
It has multiple protection functions such as overcurrent protection, short circuit protection, grounding protection, etc., which can quickly and accurately cut off faults and ensure the safety of power grids and equipment.
Easy operation and maintenance
The operating mechanism is simple and clear, and the operation is convenient and fast. At the same time, the maintenance of the equipment is also very convenient, reducing maintenance costs and downtime.
Wide range of application scenarios
Applicable to urban power grids, industrial parks, commercial centers, residential areas and other places, providing stable and reliable power supply for all types of users.
Strict quality control
During the production process, we strictly follow the relevant international and domestic standards, and conduct strict quality inspections on every component and production link to ensure stable and reliable product quality.
Choosing the XGN15-12 high-voltage ring main unit will provide efficient, stable and safe protection for your power system, and is your trustworthy power equipment choice.
