XGN口-12(SF6)
SF6 Ring Main Unit
The XGN-12 AC medium-voltage metal-enclosed ring main unit is used in 12kV distribution systems. It is capable of achieving both ring network power distribution and radial power distribution. The unit features a compact size and a space-saving design, which significantly reduces the footprint of switching stations or distribution substations. The switchgear is widely used in the construction and renovation of urban power grids.
Features
● According to the standard: GB/T3906-2020 GB/T3804-2017 BG/T16926-2009 GB/T1985-2023 DL/T404-2018 DL/T486-2021
● Rated voltage: up to 12 kV
● Frequency: 50Hz
● Rated current: 630A
● Maximum breaking capacity of the circuit breaker: 31.5kA
● Load switch withstand current: 20kA
● Short time withstand current of the main circuit: 20 kA for 4s
Strength
● High reliability/high security:All high-voltage live parts are sealed within a gas tank insulated with SF6, greatly enhancing insulation performance. The gas tank is securely grounded, ensuring that operators cannot come into contact with high-voltage live components. The switch features a reliable arc-quenching channel and has passed internal arc tests at 20 kA/1s.The cable compartment cover and switch status are equipped with reliable mechanical interlocks.
● Mature technology:Equipped with a domestically advanced robotic automatic welding system, the sealed SF6 gas tank is a closed system with a lifespan exceeding 30 years and an annual leakage rate of less than or equal to 0.01%.
● Minimal Environmental Impact: All high-voltage live parts are sealed within a stainless steel gas tank with an IP67 protection rating, making it suitable for use in highly humid, polluted, high salt mist, and high-altitude environments.
