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Withdrawable Mechanism：Critical components (e.g., circuit breakers) can be easily withdrawn, allowing swift maintenance or replacement without disrupting the entire system, reducing downtime.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.
