However, it is known that the cable length is relatively long, and when it is necessary to use a plurality of cable clamps, which fix the cable on the horizontal bridge, there is a high possibility of angular misalignment, so that the interaction of several cable clamps tends to twist the cable. Therefore, the cable torsional stress can not be released for a long time, so that the cable protective layer and the cable core can be staggered, and the protection effect of the cable protective layer on the cable core is further influenced.
The applicant finds that the technology shows that a rubber layer is attached to the inner wall of the cable clamp and used for protecting the cable, and mainly aims to prevent the cable from being directly extruded by the metal edge of the cable clamp when the cable expands with heat and contracts with cold so as to prevent the cable protective layer from being damaged by cutting. However, the rubber layer has small stress releasing capacity, the rubber layer is loosened frequently due to expansion caused by heat and contraction caused by cold of the cable, and when the cable expands, the cable is not provided with a good releasing space due to extrusion stress, and the effect is general. When a general cable fixing clamp clamps a cable, the cable is easy to be limited because torsional stress exists during installation, the protection effect of a cable protection layer on a cable core is further easily influenced, and the stress existing in expansion and contraction of the cable is difficult to release, so that a prestress type cable fixing clamp is needed.
