XGN15A-12 Metal-Enclosed Switchgear
The XGN15A-12 is an advanced, metal-enclosed switchgear featuring vacuum arc-extinguishing technology and a robust composite insulation system (epoxy resin and air). Designed as a superior upgrade to traditional fixed-type and HXGN-series units, it offers enhanced safety and modular flexibility for modern power grids.
Description
Key Features
-
High-Performance Switching: Equipped with ZN57 and FZN57 compact vacuum switches and a built-in independent isolating switch.
-
Modular & Versatile: Circuit breaker, load switch, and combined apparatus cubicles share uniform dimensions, allowing for flexible modular combinations.
-
Enhanced Safety Design: A, B, and C compartments are arranged vertically with through-wall insulating bushings to ensure maximum operational security.
-
Ideal Replacement: A direct, high-efficiency replacement for traditional HXGN-series switchgear (FZN25, FZN21, or SF6 variants).
