Product introduction
The Aierway QH-12JYT(FH)-A2 is a specialized export-oriented composite switchgear designed for 10kV medium-voltage distribution networks in international markets. As a “Composite” type switchgear, it integrates multiple functions—typically a load break switch (LBS) and fuse protection—into a single, compact, and maintenance-free unit. The designation “(FH)” often refers to its specific design features, such as “Fully Insulated” or “Flush Mounting” capabilities. This product meets stringent international standards and is tailored for applications requiring high reliability, safety, and adaptability to diverse environmental conditions.
Key Features & Advantages
– All-in-One Protection: Combines switching, isolation, earthing, and fuse-based protection in one unit, reducing footprint and installation complexity.
– Maintenance-Free Operation: Sealed insulation requires no internal inspection or cleaning, minimizing lifecycle costs.
– Enhanced Safety: Fully insulated design prevents accidental contact with live parts; visible earthing and isolation ensure operator safety.
– Global Compatibility: Designed for international voltages (10kV), frequencies (50/60Hz), and mounting practices (flush, wall, pole, or ground).
– Robust for Harsh Environments: Corrosion-resistant materials and sealed construction suit tropical, coastal, or industrial areas.
