Product introduction
The Aierway KYN61-40.5 is a state-of-the-art, armored, removable alternating current (AC) metal-enclosed switchgear designed for medium-voltage power distribution and control applications. It is engineered to provide reliable, safe, and efficient operation in demanding electrical environments, typically rated for 40.5 kV systems.
Key Features
1. Advanced Metal-Enclosed Design
-Constructed with robust, fully enclosed armor casing, offering enhanced protection against environmental factors, mechanical impact, and unauthorized access.
– Compartments are segregated to ensure operational safety and minimize risk.
2. Removable (Draw-Out) Mechanism
-Features a modular, draw-out design for key components such as circuit breakers, allowing for easy maintenance, testing, and replacement without de-energizing the entire system.
– Ensures minimal downtime and improved serviceability.
3. High Safety and Reliability
– Complies with international standards (e.g., IEC, GB) for insulation, dielectric strength, and arc resistance.
– Equipped with safety interlocks, earthing switches, and fault protection mechanisms to prevent operational errors and ensure personnel safety.
4. Optimal Electrical Performance
-Rated for a maximum voltage of 40.5 kV, with high breaking capacity and thermal stability to handle overload and short-circuit conditions.
-Low power loss design contributes to energy efficiency.
