Embodiment Construction

[0012] The conductor is tinned copper wire, and the insulated wire composed of extruded foamed polyethylene insulation outside the tinned copper wire is the control wire. A foamed polyethylene insulating layer is extruded outside the tinned copper conductor, and the insulating wire wrapped with an aluminum-plastic composite tape layer on the insulating layer is a power cord. The insulated wire formed by extruding foamed polyethylene insulation on the outside of the tinned copper wire is the signal wire. Twisting 13 control wires, 6 power wires, and 8 signal wires into a cable core, the signal wire is arranged in the middle of the cable core, the control wire and power wire are arranged around the signal wire, and the gap between the cable core is filled. On the cable core, the high-quality synthetic mica tape material is wrapped around the cladding layer, the glass fiber cloth tape winding layer, and the copper wire shielding layer is braided on the glass fiber cloth tape wind...

Abstract

The invention discloses a method for manufacturing a signal measurement and control cable and belongs to the technical field of cables. The method includes the following steps that an expanded polyethylene insulating material is extruded and wrapped on the outside of a tinned copper wire to form an insulated wire serving as a control line, an expanded polyethylene insulating layer is extruded and wrapped on the outside of a tinned copper conductor, an aluminum plastic composite strip layer is wrapped on the insulating layer to form an insulated wire serving as a power line, the expanded polyethylene insulating material is extruded and wrapped on the outside of the tinned copper wire to form an insulated wire serving as a signal line, the control line, the power line and the signal line are stranded to form a cable core, a mica tape, a glass fiber cloth and a woven copper wire shielding layer are sequentially wrapped on the cable core, and a protecting jacket is extruded and wrapped on the cable core. The method for manufacturing the signal measurement and control cable has the advantages that the method is scientific and simple, the cable is compact, reasonable and simple, the tinned copper wire is used for the conductor, the stability of transmission performance of the cable is guaranteed, the expanded polyethylene insulating material is used for internal insulation, low capacitance, low attenuation and resistance to intense electromagnetic interference of the cable can be achieved, an audio signal and a digital signal can be simultaneously transmitted, and the requirement of simultaneously transmitting same signals by the cable can be met.

Description

technical field [0001] The invention relates to a method for manufacturing a signal measurement and control cable, which belongs to the technical field of cables. Background technique [0002] With the development and progress of society and the advent of the information age, the vigorous development of information technology and the wide application of electronic computers have become important symbols of industry modernization. For example, the development of military modernization, the development of rail transit, and the control systems and electronic equipment systems in various equipment require a large number of high-performance signal measurement and control cables. The existing signal measurement and control cables have poor environmental resistance and anti-interference performance, which cannot meet the above requirements. Contents of the invention [0003] The purpose of the present invention is to provide a method for manufacturing a signal measurement and co...
