Vacuum ring main unit

metal-cladSF6power distribution

Overview
HXGN series metal-enclosed ring main unit switchgear designed for modular, high-protection distribution network applications.

Key features

• Flexible Switch Configuration: Supports domestic FLN36 or ABB SFG-type SF6 load switches, with optional imported permanent magnet operating mechanisms or domestic VB series vacuum circuit breakers; offers manual and electric operation modes.
• High-Precision Modular Cabinet: Constructed from imported aluminum-zinc coated steel plates, formed by CNC machining to achieve high structural strength and superior protection performance.
• Multi-Level Safety Interlocks: Integrated mechanical interlocks and anti-misoperation designs to ensure operational reliability and safety.

Details
The product is provided as a metal-enclosed ring main unit switchgear with modular cabinet design. The cabinet uses aluminum-zinc coated steel plates processed by CNC forming to ensure structural integrity and protection. Switching element options include SF6 load switches (FLN36 or ABB SFG-type) and VB series vacuum circuit breakers; permanent magnet drive mechanisms are available as an imported option. Mechanical interlocks and anti-misoperation measures are integrated to enhance safety during operation.
