The common types of tension clamps include bolt type tension clamps, wedge type tension clamps, bolt type compression tension clamps, and compression type tension clamps.
1. A tension clamp that is not used as a conductor.
In power transmission and distribution lines, the limit price bears the tensile force of the wire or ground wire, so the limit price should not be less than 95% of the rated breaking force of the wire or ground wire in the socket to ensure the safety of the line. However, these types of tension clamps are not used as conductors, so they have lower electrical performance requirements.
Moreover, this type of tension clamp can be disassembled and reused after installation, making it a movable clamp that is relatively easy to maintain and replace. These types of clamps are mostly bolt type and wedge-shaped tension clamps.
2. As a tension clamp for conductors.
This type of tension clamp not only needs to withstand the tensile force of the wire or ground wire, but also serves as a conductor integrated into the operation of the wire or ground wire. It requires high electrical performance and has certain limitations in terms of resistance, wire resistance, and temperature rise.
Moreover, this type of wire clamp, due to its conductive function, cannot be disassembled or replaced after installation, so it is also known as a "dead wire clamp". Its types are mostly various types of compression clamps.
The conductivity and non conductivity of wire clamps determine their installation differences, and these two factors simultaneously dominate the classification standards of wire clamps. The use of various tension clamps in China's power transmission and distribution lines ensures the safe operation of Xi'an Road, and its value is obvious.
