In power engineering, tension clamps are essential hardware for anchoring and securing conductors or ground wires. They not only mechanically fix the conductors and ground wires but also provide anchoring. These clamps vary in design and installation conditions, and can therefore be divided into two main categories. The first type of tension clamp can withstand the full tension of the conductor or ground wire, with a clamping force of at least 90% of the rated tensile strength of the installed conductor or lightning protection wire, and does not act as a conductor. These clamps can be easily removed after conductor installation for reuse, including bolt-type and wedge-type tension clamps. The second type of tension clamp not only withstands tension but also acts as a conductor, therefore it cannot be removed after installation and is called a dead clamp. Due to its conductive nature, its installation must strictly follow relevant operating procedures.
In addition, there are hydraulic tension clamps, specifically designed for hydraulically splicing conductors, and compression tension clamps, which consist of a conduit, a drain plate, a drain clamp, and a steel anchor.
