Product Overview
  • Metal-Clad Compartmentalization: The enclosure is divided by earthed metal partitions into separate compartments (e.g., circuit-breaker compartment, busbar compartment, cable compartment, relay/instrument compartment) to prevent fault propagation.
  • Withdrawable Design: Core components (e.g., circuit breaker) are mounted on a withdrawable truck, facilitating quick isolation, maintenance, and replacement, reducing outage time. Clear "Service," "Test," and "Disconnected/Withdrawn" positions are defined.
  • Air as Primary Insulation: Uses atmospheric air as the main insulation medium, offering a relatively traditional structure and cost-effectiveness.
  • Comprehensive Interlocking System: Features strict mechanical interlocks ensuring the truck can only be moved when the breaker is open; the breaker can only be operated when the truck is in the correct position (Test or Service); and preventing earthing switch closure on live circuits, etc.
  • Flexible Main Circuit Schemes: Offers a wide range of standardized main circuit schemes that can be selected and combined according to different distribution needs, providing strong applicability.
