Product Description

12-24kV Semi-Insulated Ring Main Unit

A cost-effective and high-performance preferred equipment for medium-voltage power distribution, featuring modular and compact design. Applicable to residential quarters, commercial complexes, municipal power distribution, and industrial auxiliary power supply.

⚙️Cost-Effective Distribution

The semi-insulated structure precisely meets small and medium-load needs, optimizing production costs while maintaining core performance compared to fully insulated units.

📦Modular & Compact Design

Narrow width and small volume allow flexible arrangement in corridors and box-type substations. Supports unitized combination and fast on-site assembly.

🛡️Stable & Reliable

Covers rated currents of 630-1250A with short-circuit capacity up to 25kA. Uses mature vacuum interrupter technology for long mechanical life.

✅Five-Prevention Interlocking

Equipped with mechanical interlocking to eliminate misoperation. Full front-operation design allows routine inspection without specialized teams.
