Circular shielding control towline cable and production method thereof

Abstract

The invention relates to a circular shielding control towline cable and a production method thereof. The cable comprises, from inside to outside, sequentially a cable core, a first wrapping layer (2) used for wrapping the cable core, an inner lining layer (3) used for wrapping the first wrapping layer (2), a braided layer (4) used for wrapping the inner lining layer (3), and an outer protection layer (6) used for wrapping the braided layer (4). The cable core is formed by intertwisting a plurality of insulation core wires (1), and the plurality of insulation core wires (1) can be fixedly bound together to form one integrated body by the first wrapping layer (2). The circular shielding control towline cable is not easy to disperse, and has advantages of good integrity, strong anti-bending capability, and long service lifetime.

Description

technical field [0001] The invention relates to a wire and cable, in particular to a circular shielded control drag chain cable and a preparation method thereof. Background technique [0002] With the improvement of electrical automation, there are more and more occasions where equipment units need to move back and forth. In order to prevent cables from being entangled, worn, pulled off, and broken, cables are often placed in cable drag chains to protect the cables. In actual use, the wires and cables of the towline system are often bent back and forth along with the towline, which puts forward high requirements on the bending and tear resistance of the wires and cables of the towline system. [0003] However, the conductor part of the inner core wire of the existing towline system wire and cable is made of thick copper wire twisted, the service life, bending resistance and tear resistance are very limited, and it is easy to break and affect the physical and electrical prope...

Problems solved by technology

[0003] However, the conductor part of the inner core wire of the existing towline system wire and cable is made of thick copper wire twisted, the service life, bending resistance and tear resistance are very limited, and it is easy to break and affect the physical and electrical properties of the cable; and When the existing drag chain system is in use, the wire cores composed of multiple insulated core wires are easy to disperse, so that the integrity of the wire and cable cannot be guaranteed
