Seven elements of 500KV steel core aluminum stranded wire production

1. There must be a certain tension when the wire is laid, and the wire plate should be loosened to prevent the steel wire from falling apart.

2. The pre-twist ring spacing adjustment should be consistent with the wire pitch. The distance between the die holder and the pre-twist ring should be appropriate.

3. The tension of the aluminum wire reel should be adjusted to be uniform and uniform to avoid the wire being serpentine.

4. Aluminum monofilament is strictly prohibited from colliding with the injury line during the transportation process.

5, often check the tightness of the stamper, replace the stamper in time to avoid the phenomenon of single-line wrong stock.

6. Avoid wire scratches between the wires when wiring. If necessary, the paper should be placed between the layers.

7. Before starting the car, check the twisted body and take-up line to ensure that no one at the twisted body, the protective net is in place, and the wire at the take-up line is in place to start the driving process. After the alarm is sounded, the car can be speeded up. It is strictly forbidden to drive without an alarm bell.

8. Strengthen the monitoring of the inner layer and the adjacent outer layer of the strand, and strictly prevent the long rice section from entering the strand after the single line is broken. In case of disconnection, the welding repair should be stopped in time.

9. Special emphasis: due to the agreement, the outer layer is not allowed to have solder joints. The outer layer must be cold-welded when the wire is broken. The identification card and the storage list should indicate the solder joints to facilitate communication and negotiation with customers. The inner layer can be soldered with resistance but must be annealed. When the inner layer breaks into the pipe body, it must be welded and processed for re-production. It is strictly forbidden to report the welding without further welding, and the serious consequences will be legally responsible.
