What Is KYN28-24KV Switchgear?
KYN28-24 is a metal-clad and metal-enclosed indoor switchgear equipped with withdrawable vacuum circuit breakers. Its modular construction allows for safe, efficient medium-voltage power distribution and system control. It supports single busbar, sectionalized, or double busbar configurations, offering adaptable power layouts.
Key Advantages
-
Withdrawable Design: Circuit breakers are mounted on a truck unit for fast replacement or maintenance without de-energizing the system.
-
Arc-Resistant Structure: Designed with pressure relief channels and compartmental isolation to enhance operator safety.
-
Space Optimization: Compact footprint without compromising on insulation and clearance standards.
-
Front Access for Wiring: Installation and maintenance can be conducted directly from the front—ideal for confined spaces.
-
Interlocking Mechanism: Five-proof interlocks prevent misoperation and enhance operational reliability.
How It Differs from Fixed-Type Switchgear
Unlike fixed-type switchgear, which requires complete system shutdown during breaker maintenance, KYN28-24’s withdrawable design allows the breaker unit to be pulled out safely and swiftly—minimizing downtime and improving system resilience.
| Feature | KYN28-24 Withdrawable | Fixed-Type Switchgear |
|---|---|---|
| Maintenance Flexibility | High | Low |
| Safety During Service | Excellent | Moderate |
| Initial Cost | Slightly Higher | Lower |
| Long-Term OPEX | Lower (due to easier maintenance) | Higher |
Purchasing Tips & Selection Guide
When selecting KYN28-24 switchgear, consider the following:
-
System Voltage & Current: Choose the right rated current and short-circuit capacity based on your network analysis.
-
Circuit Breaker Brand: For critical systems, you can request high-quality vacuum circuit breakers such as ABB, Schneider or Siemens.
-
Environment: Ensure your space supports front-access configurations and proper ventilation.
-
Expansion Requirements: Modular design allows scalability—plan for future load growth.
💡 Tip: For renewable energy integration or smart grid systems, consider digital protection relays and communication-ready options (Modbus, IEC 61850).
