Shaped parallel groove wire clips

2024-11-25

During the installation and operation of a tie line tower, the pulling force of the tie line needs to be precisely adjusted to ensure that the force is in a balanced state. In order to facilitate the installation and subsequent adjustment of the cable, adjustable cable clamps are usually placed in the area around the lower extension of the cable. Adjustment of the tie line can be accomplished with the aid of either basket screws or wedge-shaped UT-shaped tensioning clips, although the use of basket screws for adjustment of the tie line in towers has become less common in today's line conditions. The wedge-shaped UT-shaped tensioning clamp consists of a wedge mother, a wedge and a long U-shaped screw with a certain adjustment range. These clamps are not only used for stabilizing the tension wire, but also for adjusting the length of the wire and are suitable for the installation of GJ-25 to GJ-70...

2024-11-21

　Tension clamp (tension clamp, strain clamp, dead-end clamp), as an important fixture, is mainly used to fix the wire, so that it can withstand the wire tension, and the wire is properly hung to the tensioning string or tower. From the point of view of the structure and installation conditions, tensioning wire clamps can be roughly divided into the following two categories: non-conductive detachable tensioning wire clamps This type of tensioning wire clamps need to withstand all the tension of the wire or lightning line. The clamp holding force is required to be not less than 90% of the rated tensile strength of the installed conductor or lightning conductor, and does not function as a conductor of electricity. A significant advantage is that this type of wire clip can be removed after completion of the wire installation for separate use in other applications. Common types of this type of wire clip include bolt type tensioning clips and wedge type tensioning clips. Screw...
