Note: The XGN15-24 single-unit SF6 ring main unit switchgear consists of the following 4 parts: Busbar compartment ② Mainswitch
③ Cable compartment ④Operating mechanism, interlocking mechanism, and low-voltage control.
1. Busbar Compartment: The busbar compartment is arranged at the top of the cabinet. In the busbar compartment, the mainbusbars are connected together, spanning the entire row of switchgear.
2. Load Break Switch: The switchgear is equipped with an SF6 load break switch (FLN36 or FLN56). The housing of the load breakswitch is cast with epoxy resin, filled with SF6 gas as insulation medium, and has observation holes on the shell. The switchgearcan be equippedl with an SF6 gas density meter or a gas density monitor with an alarm contact according to customerrequirements.
3. Cable Compartment: The load switchgear has a spacious cable compartment mainly used for cable connections. This allowssingle-corel or three-core cables to be connected with the simplest unshielded cable heads. Adequate space can alsoaccommodate components such as surge arresters, current transformers, and downstream grounding switches. According tostandard design, the cabinet door hasl observation windows and a safety interlock device. The cable compartment floor isequipped with a sealing cover and appropriately sizedl cable clamps with support frames. The cable compartment floor and thedoor frame can be removed for easy cable installation.
4. Operating Mechanism, Interlocking Mechanism, and Low-voltage Control Compartment: The low-voltage compartmentl withinterlocking also serves as a control panel. The low-voltage compartment is equipped with a spring operating mechanism withl aposition indicator and a mechanical interlock device. It can also be equipped with auxiliary contacts, trip coils, emergencyl tripmechanisms, capacitive live displays, key locks, and electric operating devices. The entire upper unit can be replaced.

The XGN15-24 single-unit ring network switchgear produced by our company is made of aluminum-zinc plates processed by CNC machine tools and riveted, making it more aesthetically pleasing, more robust, and more stable in performance compared tol traditional products from other enterprises. SF6 ring network cabinets have many advantages, including small size (width 500mmx height 2000 x depth 1200mm), simple structure, maintenance-free, reasonable price, and more, making it highly favored in the market. Our products have been widely used and operated safely in Jiangsu.
