Description

Product Description

The Ringmaster C is a high-performance medium-voltage ring main unit (RMU) engineered for reliable power distribution in 12–24kV networks. Designed by Schneider Electric, it combines compact construction, robust safety features, and low maintenance requirements, making it ideal for urban/rural distribution grids, commercial buildings, industrial facilities, and critical infrastructure. Its versatile design supports ring, radial, and spur network configurations, delivering consistent performance in harsh outdoor and indoor environments.

Key Features

  1. Enhanced Safety      Protection: Equipped with built-in safety interlocks and no exposed live      parts, complying with the latest IEC standards for internal arc      classification to ensure operator and pedestrian safety.

  2. Compact & Robust      Design: Space-saving structure fits limited installation areas, with a      durable enclosure resistant to dust, moisture, and extreme weather      conditions for long-term reliability.

  3. Minimal Maintenance Needs:      Vacuum circuit breaker (VCB) with high mechanical endurance and      maintenance-free components reduces operational downtime and long-term      costs.

  4. Easy & Fast      Installation: Pre-assembled and factory-tested modules enable quick      on-site deployment, minimizing construction cycle and      labor requirements.

  5. Remote Monitoring &      Control: Supports smart connectivity solutions, allowing real-time      monitoring of electrical parameters, remote operation, and predictive      maintenance.

  6. Flexible Expandability:      Fully extensible on both sides, compatible with standalone vacuum circuit      breakers, ring switches, and auxiliary modules to adapt to evolving      network needs.

  7. High Operational      Reliability: Rated short-time withstand current for stable performance      during fault conditions, with a proven track record in diverse power      distribution scenarios.

  8. Environmental      Friendliness: Recyclable materials and low environmental impact design      align with global sustainability goals, reducing carbon footprint.

  9. Wide Environmental      Adaptability: Operates stably in extreme temperatures (-30℃ to +55℃), high      humidity, and high-altitude regions, suitable for both indoor and outdoor      installations.

Application Scenarios

  1. Urban & Rural      Medium-Voltage Distribution Grids: Ideal for branching and distributing      power in residential areas, suburban communities, and rural towns. Its      compact design fits narrow installation spaces, while reliable performance      ensures uninterrupted power supply for households and small businesses.

  2. Commercial & Public      Facilities: Suitable for shopping malls, hotels, office buildings,      hospitals, and airports. Supports 24/7 stable power distribution, remote      monitoring meets facility management needs, and safety features protect      dense human traffic areas.

  3. Industrial Parks &      Manufacturing Plants: Powers production lines, auxiliary equipment, and      warehouse facilities. Withstands industrial environment disturbances,      flexible expandability adapts to production capacity expansion, and low      maintenance reduces factory downtime.

  4. Critical Infrastructure:      Deployed in tunnels, underground railways, and renewable energy      (solar/wind) grid-connection points. Resists harsh operating conditions,      internal arc protection ensures infrastructure safety, and smart control      supports integrated grid management.

  5. Data Centers &      Telecommunication Facilities: Provides stable medium-voltage power input      for data centers and telecom hubs. High reliability prevents power outages      affecting critical IT operations, and remote monitoring enables real-time      fault detection.
