Product introduction
The Aierway 24kV Center Distance 310mm is a high-performance, fixed-assembly medium-voltage switchgear featuring epoxy resin solid-sealed pole terminals and an extended 310mm phase-to-phase center distance. Designed for demanding 24kV applications, it combines advanced solid insulation technology with a robust fixed design to deliver maximum reliability, safety, and longevity in utility, industrial, and infrastructure power distribution networks.
Key Features
1. Absolute Insulation Integrity: No gas leakage, no pressure monitoring, no degradation from moisture/pollution.
2. Ultimate Operator Safety: Live parts are completely inaccessible during operation or maintenance.
3. Exceptional Mechanical Stability: The solid casting provides resistance to vibration, shock, and thermal cycling.
4. Maintenance-Free Operation: No internal components require adjustment, cleaning, or replacement.
