RRF3Z1(AS)-AL Cable Application
- Feeder cables: These carry high-current DC power from traction substations to substation nacelles and switch points along the track.
- Parallel cables: These run parallel to the track and regularly feed overhead lines (catenary systems). This reduces voltage drops over long distances, ensuring adequate power even for trains far from the substation.
- Tunnel installations: These are the primary applications. Their stringent fire protection (HFFR) properties make them ideal for confined underground spaces, particularly where passenger safety is paramount.
- Switchgear and substation connections: These connect transformers, rectifiers, and high-voltage switchgear within the substation.
