Product Overview
The XGN15-12/630-20 and XGN15-12/125-31.5 are advanced indoor metal-enclosed switchgear units operating at a rated voltage of 10kV and a frequency of 50Hz. Engineered for maximum flexibility, this series supports double radiation and ring network power supply, serving as a vital control and protection device for electrical equipment. Its compact frame makes it particularly suitable for pre-fabricated box-type substations, urban industrial enterprises, and public infrastructure.
Product Features & Advantages
- Multi-Compartment Isolation: The unit is divided into busbar, switch, cable, and low-voltage compartments by steel plates, ensuring that a fault in one section does not compromise the entire cabinet.
- Advanced SF6 Insulation: The load switch is housed in an APG-cast epoxy resin shell filled with SF6 gas, offering superior arc-extinguishing properties and high dielectric strength.
- Total Safety Interlocking: Features a sophisticated mechanical interlocking mechanism that prevents misoperation between the load switch, grounding switch, and the cabinet door.
- Visible Contact Status: Equipped with transparent, hot-pressed plastic end caps at the operating shaft, allowing personnel to visually confirm contact positions.
- High Scalability: Designed for easy horizontal expansion of main busbars, allowing the RMU to be customized and extended into any configuration required by the distribution scheme.
- Automation Ready: Supports the installation of motorized operating mechanisms (D) and microcomputer protection relays for smart grid integration.
Structural Details
- Busbar Compartment: Located at the top for horizontal connectivity and simplified expansion between multiple units.
- Load Switch Compartment: Utilizes a three-position (or two-position) load switch. Includes an optional SF6 gas density meter for real-time pressure monitoring.
- Cable Compartment: Provides ample space for non-shielded cable heads, surge arresters, and current transformers. Includes a large observation window for safe monitoring.
- Low-Voltage Control Room: Functions as the brain of the unit, housing the spring-loaded mechanism, metering instruments, auxiliary contacts, and emergency trip coils.
