In the field of modern communications and power transmission, ADSS optical cables are widely used. As a component to ensure the stable operation of the optical cable, the helical suspension clamp for ADSS is very important for the correct installation of the optical cable. This article will introduce you in detail the installation steps and main points of helical suspension clamp for ADSS.
A series of preparations must be carried out before installation, including the inspection of materials and tools and the verification of optical cable parameters. Specifically, carefully check the components of the helical suspension clamp for ADSS to make sure that there is no damage, deformation or missing. The main components usually include preformed wire, rubber clamps, aluminum splints, U-shaped hanging rings, etc. At the same time, prepare the required tools for installation, such as markers, thin tape, wrenches, etc., and confirm that the tools are complete and can be used normally. Then reconfirm the specifications of the ADSS optical cable, such as outer diameter, rated tensile strength, etc., so that the optical cable can be adapted to the selected suspension fixture. Optical cables of different specifications need to be matched with corresponding types of fixtures, which is the basis for ensuring the installation quality and the safe operation of optical cables.
The specific installation steps of helical suspension clamp for ADSS can be divided into four steps. The first step is to use thin tape or a marker pen to mark the central position of the suspension point of the optical cable. This mark is the key anchor point for subsequent installation. The second step is to preformed a single preformed wire into a bundle in a group of two to three. Align the marks in the center of these sub-beams with the installation marks made on the optical cable in the first step, and then wrap the sub-beams around the optical cable three to four times. Repeat this operation to wrap all the remaining sub-bundles. During the operation, pay attention to aligning the center color mark of each sub-bundle, and finally wrap all the ends of all the sub-bundles flat with your bare hands at once. The third step is centered on the center color mark of the preformed wire that has been wound. Carefully divide the fixture into upper and lower halves and insert it on the outside of the preformed wire, and temporarily fix it with a thin piece of tape to prevent movement. Next, take the center of the upper part of the fixture as the center, place the outer preformed wire parallel to the optical cable, so that their center color marks are aligned, and at the same time, make the curve of the outer preformed wire fully match the curved surface of the fixture, and then wrap the outer preformed wire two to three times on each side of the fixture. In the same way, install an outer preformed wire in the lower half of the fixture until all the outer preformed wires are installed. During the installation process, the gap between the twisted wires should be uniform and there is no intersection. Finally, the two ends of the outer preformed wires should be wound flat and natural with bare hands. The last step is to take the center of the overhanging clamp as the center, insert the aluminum splint clamp on the outside of the outer preformed wire, and pay attention to the hanging ears of the aluminum splint upward. After that, fix the U-shaped hanging ring to the fastening fixture of the iron tower or cement pole, tighten the nut, and install the closing pin, so as to complete the installation of the entire helical suspension clamp for ADSS.
There are also some precautions when installing the helical suspension clamp for ADSS. For example, during the operation of winding the preformed wire, it must be operated with bare hands and cannot be forcibly wound with tools to prevent damage to the optical cable and fixture components. And after the installation is complete, the installation status of the helical suspension clamp for ADSS must be thoroughly checked, including whether the connection of each component is tight, whether the nut is tightened, and whether the closing pin is in place, so that the suspension clamp can firmly fix the optical cable.
