Aierway Embedded Poles 24KV Ejection

The Aierway Embedded Poles 24kV is an advanced solid insulated switchgear (SIS) that utilizes epoxy resin-encapsulated (embedded) vacuum interrupter poles as its core insulation technology. This design represents the latest generation of medium-voltage switchgear, offering superior safety, compactness, and environmental sustainability for 24kV applications. The “Ejection” designation refers to its fully insulated, plug-and-play separable cable connectors that allow for safe, tool-less cable connection and disconnection.
