Problems solved by technology

[0002] After the cable laying construction, it is often necessary to add new cables. In the existing technology, in order to add new cables, it is necessary to carry out secondary processing on the laying site. Not only is the construction space limited, but also time-consuming, laborious, and inefficient. The requirements for operators are high, and it is necessary to avoid the possible problems of cable bundling, cable sagging between brackets, cable crossing, and chaotic routing that may exist in the secondary laying of cables. It is also necessary to avoid damage to the laid cables and reduce the cable Service life, bring safety hazard

Abstract

The invention provides a reserved power cable and a preparation method thereof, a hollow copper pipe provided with an extruded insulating layer is added in a cable core, and a traction rope is arranged in the hollow copper pipe. A required cable can be connected with a steel wire rope in a reliable mode during secondary cable laying, reasonable traction is conducted at the other end of the copperpipe, the cable needing to be laid can be placed at a set position, and the construction cost and the construction time are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a reserved power cable and a preparation method. Background technique [0002] After the cable laying construction, it is often encountered that new cables need to be added. In the prior art, in order to add new cables, secondary processing must be carried out on the laying site. Not only is the construction space limited, but also time-consuming, laborious, and inefficient. The requirements for operators are high, and it is necessary to avoid situations such as loose cable binding, cable sagging between brackets, cable crossing, and chaotic routing that may exist in the secondary laying of cables. It is also necessary to avoid damage to the laid cables and reduce cable service life and bring safety hazards. Contents of the invention [0003] The purpose of the present invention is to propose a reserved type power cable and its preparation method, so that it is convenient to ad...
