Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0021] As a first aspect of the present invention, a cable shaping tool for power transmission lines is provided, such as figure 1 As shown, the cable shaping tool includes a shaping part 1 and a driving device 2, and the shaping part 1 is connected to the driving device 2.

[0022] The cable shaping tool of the present invention includes a shaping part 1 for contacting the cable to be shaped and a driving device 2 for driving the shaping part 1, wherein the stroke of the driving device 2 is the amplitude of the cable bent into a sinusoidal wave. For example, when laying in a vertical serpentine shape, at first, the cable shaping tool is fixed above the midpoint of two adjacent fixed points of the cable; then, the driving device 2 driving the cable ...

Abstract

The invention provides a cable reshaping tool for a power line and a cable bending method. The cable reshaping tool for the power line comprises a reshaping part and a driving device, wherein the reshaping part is connected with the driving device. The reshaping part of the cable reshaping tool is driven by the driving device to push and press a cable so as to bend the cable, and the manual operation is replaced by multiple times of bending for reshaping, so that the S-shaped laying of the cable is achieved.

Description

technical field [0001] The invention relates to the field of electric power, and more specifically, relates to a cable shaping tool for power transmission lines and a cable bending method. Background technique [0002] In the prior art, the 110kV cable cloth is generally laid by the serpentine laying method, in which the vertical serpentine laying method requires the horizontally arranged cables to make a sinusoidal waveform whose wave surface is perpendicular to the ground according to a certain amplitude. [0003] There is no corresponding special tool for the method of vertical serpentine laying, and the cable is bent by manpower when the cable is erected. Since the diameter of the 110kV cable is generally more than 100mm, the weight is generally more than 10kg / m, and the maximum can reach 35kg / m, and the cable generally adopts a fully enclosed aluminum sheath, so it is difficult to bend the cable manually. It is difficult to shape the cable manually, and the shaped cabl...
