Pre twisted wire tension clamps are often made of galvanized steel wire or aluminum clad steel materials in terms of manufacturing process, and their mechanical properties can fully meet the needs of various power transmission and distribution lines. Therefore, what should be paid attention to when installing pre twisted wire tension clamps?
Although the installation of pre twisted wire tension clamps is relatively simple, there are still many key points to pay attention to during installation.
Firstly, the structure of the pre twisted wire tension clamp is quite unique and can only be used once. Reusing will reduce the mechanical performance of the pre twisted wire tension clamp and fail to meet the requirements of the circuit design.
Secondly, before installation, it is necessary to choose a suitable pre twisted wire tension clamp based on the type of wire, so as to ensure compatibility with the wire and ensure the safety of the circuit.
Finally, it is not allowed to overlap wires on the pre twisted wire tension clamp, but it is allowed to overlap wires before and after the pre twisted wire tension clamp.
When using pre twisted wire tension clamps for wire connection, it is also necessary to ensure that the rotation direction of the twisted wire is consistent with the rotation direction of the pre twisted wire tension clamp, so as to ensure that the pre twisted wire tension clamp has a normal grip on the wire, and cannot be used in overhead ground wires. One of the installation directions is required to ensure the key point of the pre twisted wire tension clamp's grip on the wire, avoiding the danger of wire breakage and strand breakage.
