Embodiment Construction

[0024] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] like figure 1 and figure 2 As shown, according to a specific embodiment of the invention, a cable is provided, and the cable pulling assembly includes a pulling part 10 and a tube body part 20 . One end of the tube body part 20 is connected to the traction part 10, and the other end of the tube body part 20 is arranged on the wire part 50 to prevent the wire part 50 from being stretched during laying.

[0026] In this embodiment, since the tube body portion 20 is provided on the wire portion 50, the tube body portion 20 and the wire portion 50 are simultaneously subjected to the traction force during the traction process of the wire portion 50. Since the tube body portion 20 is added,...

Abstract

The invention provides a cable traction assembly and a method of preventing cable stretching. The cable traction assembly comprises a traction part; and a pipe body part, wherein one end of the pipe body part is in connection with the traction part, and the other end of the pipe body part is arranged on a wire part to prevent the wire part from being stretched in a laying process, thereby solving the problem that in the prior art, cables are easy to stretch in a laying process. The pipe body part is arranged on the wire part, allowing the pipe body and the wire part to be meanwhile under the tractive effort in the traction process of the wire part; according to the pipe body part, the wire part provided with the pipe body part and a cable over sheath are meanwhile dragged, thereby reducing expansion or displacement between the wire part and the cable over sheath, guaranteeing lead integrity, and effectively avoiding potential safety hazards caused by stretching cables in a laying process.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a cable pulling assembly and a method for preventing cable stretching. Background technique [0002] 35kV and 10kV high-voltage cable laying constructions are commonly used in various construction projects, and there are many circuits, some cables are long in length, and intermediate cable heads are required for connection in the middle. In the laying of the cable head, the cable netting is often used to fix the outer sheath for traction, and the tractor or manpower is used to draw the cable for laying, and the guide wheel and the laying machine are used to assist in laying the cable. [0003] Using this method to lay high-voltage cables often causes deviations between the outer sheath and the inner sheath, and even the position of the core, especially when the armored high-voltage cable is laid with a greater deviation of the outer sheath. In addition, after the high-voltage...
