Problems solved by technology

[0003] The traditional strong current and weak current control methods are: the strong current system and the weak current system are controlled by independent power cables and control cables respectively. The traditional production process has the following problems: 1. Large processing volume and high production cost
2. It is not conducive to laying and management, and the risk factor is large
3. It is not conducive to the assembly of finished products, and the production cycle is long
4. Large volume, waste of materials, electricity, space, cable trays, pipelines and labor for production and laying

Abstract

The invention discloses a strong and weak current composite cable and a manufacturing method thereof. The strong and weak current composite cable is formed by extruding an integrated sheath of a power cable and a control cable which share the sheath. The manufacturing method comprises the following steps of: performing wire drawing, twisting, extrusion molding and cable forming on the power cable and the control cable respectively, and then extruding the power cable and the control cable through the disposable sheath. The composite cable has the advantages of high surface finish, skillful integral appearance, small volume, space saving, material saving, cable bridge and pipeline saving, interest of mounting and paving, capability of meeting the using requirement, high dimensional precision, small error, convenient assembly, and capability of realizing zero distance control of weak current on strong current and integrated control of a power supply system; and the manufacturing method has the advantages of short production period, high yield and low production cost, and can reduce the production cost so as to improve the cost performance of the composite cable and really fulfill the purposes of high efficiency and energy conservation.

Description

technical field [0001] The invention relates to a cable and a manufacturing method thereof, in particular to a strong and weak current composite cable used in electric power engineering, remote control, and construction engineering power supply systems and a manufacturing method thereof. Background technique [0002] Electric power engineering, remote control, and construction engineering, no matter in the construction process or after they are put into use, the power supply system is particularly important. The cable is the carrier of the power supply system. The strong current system and the weak current system are controlled by power cables and control cables respectively. [0003] The traditional control method of strong current and weak current is: the strong current system and the weak current system are controlled by independent power cables and control cables respectively. The traditional production process has the following problems: 1. Large processing volume and hi...
