Embodiment Construction

[0013] A wear-resistant, halogen-free, highly flame-retardant, flexible shielded control cable, see figure 1 : including an outer sheath 1, a braided layer 2 and an inner sheath layer 3 arranged sequentially from the outside to the inside with a circular cross section, a central cavity 4 is formed in the inner wall of the inner sheath layer 3, and the central cavity 4 is set There are three core wires 5, which are specifically two power wires and one ground wire. The three core wires 5 are twisted to form an overall structure, and the outer periphery and inner sheath layer of the overall structure are formed after the three core wires 5 are twisted. A number of PP ropes 6 are filled between the inner walls of 3, and each core wire 5 includes an outer insulating layer 7 and a conductor 8 at the center.

[0014] The insulating layer 7 of the core wire 5 is specifically made of modified halogen-free flame-retardant PP material;

[0015] The PP rope 6 is specifically a reinforced...

Abstract

The invention provides a wear-resistant halogen-free high-flame-retardant flexible shielding control cable having advantages of high flame retardant performance, good low-smoke effect, high elasticity, high low-temperature resistance, good anti-electromagnetic-interference property, and high wear resistance. With the cable, normal operation of equipment can be guaranteed. The control cable comprises an outer sheath, a braiding layer, and an inner sheath layer, wherein the cross sections of the units are in shapes like circular rings and the units are successively arranged from outside to inside. A central cavity is formed in the inner wall of the inner sheath layer; three core wires are arranged in the central cavity and contain two power wires and one ground wire; and the three core wires are twisted to form an integrated structure. The space between the periphery of the integrated structure formed by twisting of three core wires and the inner wall of the inner sheath layer is filled with a plurality of PP ropes. Each core wire includes an insulating layer arranged at the outer layer and a conductor arranged at the center.

Description

technical field [0001] The invention relates to the technical field of cable structures, in particular to a wear-resistant, halogen-free, highly flame-retardant, flexible shielded control cable. Background technique [0002] Since computers, sensors, transmitters, industrial machinery and equipment, power transmission, etc. all use multi-core cables, and due to the different characteristics of the transmission signal of the wire harness, the interference and interference between the cable bundles, and the electromagnetic environment in which the complex electronic system is located It is very bad, causing the cable to be seriously affected by external interference, so a cable with very good shielding performance and anti-interference ability is required. Contents of the invention [0003] In view of the above problems, the present invention provides a wear-resistant, halogen-free, highly flame-retardant, soft shielded control cable, which has the characteristics of high fl...
