HXGN15-12(F) and HXGN15-12(FR) compact fixed AC metal-enclosed switchgear (hereinafter referred to as “switchgear”) are designed for ring-main or radial power supply systems with a rated voltage of 12 kV and a rated current up to 630 A. They are especially suitable for installation in prefabricated substations to provide control and protection for power systems. This product incorporates the FLN36-120 SF₆ load break switch or the FLRN36-12D load break switch–fuse combination unit, both housed in insulated enclosures. It features compact size, light weight, simple operation, low operating force, reliable interlocking, and maintenance-free performance—making it a new-generation high-voltage switchgear meeting the requirements of urban power grid renovation and construction.
The overall cabinet frame is manufactured from high-quality aluminum-zinc coated steel sheets through CNC precision machining and laser cutting processes. Adopting an entirely bolted assembly structure without any welding joints, the cabinet delivers high dimensional accuracy, superior structural strength, excellent corrosion resistance and lightweight performance. It features strong universality and interchangeability for modular installation and easy on-site assembly.
