Description

Technical Field

[0001] The utility model relates to the technical field of fittings for high-voltage lines, and more specifically, it relates to a multi-purpose conductor strain string. Background Technique

[0002] The multi-purpose conductor strain string is a component in the power line, which can be used to maintain the tension of the conductor, prevent the conductor from sagging or stretching excessively due to its own weight or other external force factors, and can also fix and lay the conductor, etc. It is generally composed of components such as strain insulators and fittings. The strain insulator string is used to support the conductor and insulate the conductor from the ground or other support structures to prevent electric leakage or short circuit. The fittings are used to fix and connect the conductor and the insulator string to ensure that the conductor can remain stable under various environmental conditions. Most of the traditional strain strings are connected to external equipment through bolts. When disassembling, because the bolt parts are small, if they fall, the installation efficiency will be reduced; and most of the positions of the wire clamps of the strain string are horizontally arranged, resulting in inability to fix the conductor in different directions, with poor flexibility; moreover, the channel through which the strain string passes through the conductor is relatively fixed and can only be applicable to several specifications of conductors. When the conductor is too thick, the clamping function cannot be realized. Content of the Utility Model
