Which method of joining conductors end to end features spring-loaded wedges?

The method of joining conductors end to end that features spring-loaded wedges is known as the automatic tension sleeve. This connection is designed to ensure a secure and resilient bond between the conductors. When the conductors are inserted into the sleeve, the spring-loaded wedges expand to create pressure against the surface of the conductors. This helps maintain a strong connection even under varying loads and environmental conditions, such as temperature changes or mechanical stress.

Automatic tension sleeves are particularly beneficial in overhead line applications, where maintaining a reliable electrical connection is crucial for system performance and safety. The design allows for some movement and adjustment while still ensuring that the electrical integrity of the joint is maintained. This method distinguishes itself from others, as many other joining techniques, like compression sleeves or twist joints, do not use spring-loaded mechanisms for securing the conductors.
