Description

The 40.5kV Metalclad AC Enclosed Switchgear, Withdrawable Type is a high-performance medium-voltage solution engineered for robust, reliable power distribution in large-scale industrial facilities, utility substations, and high-voltage grids. Its robust metalclad enclosure ensures superior protection, while the withdrawable design enables efficient maintenance, making it a cornerstone for stable high-voltage power management.

Application: In the system of 50Hz, 40.5kV, for power distribution, circuit control and protection.

Standards:  IEC 62271-200

Product Advantages

  • High-Voltage Resilience:Designed for 40.5kV systems, it withstands high electrical stress with advanced insulation, ensuring safe operation in demanding high-voltage networks.
  • Withdrawable Mechanism:Critical components (e.g., circuit breakers) can be easily withdrawn, allowing swift maintenance or replacement without disrupting the entire system, reducing downtime.
  • Robust Metalclad Protection:All-steel enclosure provides IP-rated defense against dust, moisture, and physical impact, enhancing durability in harsh industrial environments.
  • Enhanced Safety Interlocks:Multi-layer mechanical and electrical interlocks prevent misoperations (e.g., accidental closing under load), safeguarding personnel and equipment.
  • Scalable Configuration:Adaptable to various grid setups (incoming, outgoing, transformer connections), supporting flexible integration into complex power distribution architectures.
  • Low Lifecycle Costs:Durable construction and minimized maintenance needs (thanks to withdrawable parts) reduce long-term operational expenses, ensuring cost efficiency.
