Product introduction
The Aierway KYN550 is an advanced indoor armored removable AC metal-enclosed switchgear designed for modern, high-performance medium-voltage power distribution and control applications. Representing a progressive design in the KYN series, it combines a robust armored enclosure with a highly functional removable mechanism to deliver exceptional safety, reliability, and operational flexibility for demanding electrical systems.
Key Features
1.Superior Enclosed Design for Maximum Safety:
-Constructed with high-strength armored panels, forming a fully enclosed, compartmentalized metal structure. This design provides superior protection against the ingress of dust, moisture, and foreign objects, and contains internal arcs, safeguarding both personnel and adjacent equipment.
-Strict physical separation is maintained between the main functional compartments: busbar, circuit breaker, cable connection, and low-voltage control**. This segregation prevents fault propagation and allows for safe maintenance activities.
2.Advanced Removable (Draw-Out) Technology:
-The core switching and protection device is housed on a fully removable, truck-mounted assembly—typically a vacuum circuit breaker. This truck can be smoothly maneuvered between three key positions: **SERVICE (Connected), TEST, and DISCONNECTED (Isolated/Earthed).
Typical Applications
1.Primary and secondary power distribution in industrial complexes (chemical plants, steel mills, manufacturing facilities).
2. Power supply and control for large commercial buildings, hospitals, airports, and data centers.
3. Integration in renewable energy plant substations (solar PV, wind).
