Which type of connection may be used when the line is slack?

When the line is slack, bolted or squeeze-on connections are suitable because they can be effectively applied without the need for the line to be under tension. These types of connections provide a secure grip on the conductors, allowing for safe and reliable installation or repairs in situations where the wire is not taut.

Bolted connections use mechanical fasteners to hold the conductors together, which allows for adjustments even when the line is not tight. Squeeze-on connections, on the other hand, utilize a compression mechanism to join conductors, relying on the physical pressure to create a solid bond. Both methods can accommodate variations in line tension, making them practical for scenarios where the line may be slack.

Other options, such as full tension splices, typically require the conductor to be under tension to ensure that the splice can handle the necessary electrical and mechanical loads. Automatic splices and tension clamps also depend on the conductor being taut to create an effective connection, which is not feasible when the line is slack. Therefore, bolted or squeeze-on connections stand out as the most appropriate choice for handling slack lines.
