Description
The 3.6-24kV Metalclad AC Enclosed Switchgear (Withdrawable Type) is a high-performance power distribution solution designed for medium-voltage systems. Its robust metalclad enclosure ensures superior protection, while the withdrawable design simplifies operations, making it ideal for industrial plants, commercial complexes, and utility grids. This switchgear balances safety, efficiency, and adaptability, meeting the demands of modern power distribution networks.

Application: In 3.6~24kV power system for control, protection and monitoring.

Standards:  IEC 62271-200

Key Features
  • Broad Voltage Compatibility:Operates across 3.6kV to 24kV, accommodating diverse medium-voltage distribution needs and ensuring flexibility in grid integration.
  • Compact Design:Space-efficient structure minimizes installation footprint, making it suitable for sites with limited space, such as urban substations or indoor power rooms.
  • Easy Operation and Installation:User-friendly interfaces and modular components simplify on-site installation and daily operations, reducing setup time and operational complexity.
  • Reliable Interlock:Integrates multi-layer safety interlocks (mechanical and electrical) to prevent misoperations, ensuring personnel safety and system stability during switching or maintenance.
  • Less Maintenance:Withdrawable components allow quick disassembly and replacement without disrupting the entire system, reducing downtime and lowering long-term maintenance costs.
  • Durable Metalclad Protection:The all-metal enclosure provides excellent resistance to corrosion, dust, and external impacts, extending equipment lifespan in harsh environments.
