Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.

Referring to fig. 1, a high temperature resistant power control composite cable includes: strengthen sinle silk, control group, power group and coating.

The reinforced wire core is arranged at the center of the composite cable so as to achieve structural stability. Specifically, the reinforcing wire core is a silicone rubber filler strip 9 reinforced by a steel wire rope 8. The silicon rubber filling strip 9 can be used at 180 ℃ for a long time without performance change, has excellent breaking strength, and can improve the overall strength of the composite cable and reduce the occurrence of core breaking of a control wire core by matching with the steel wire rope 8.

The control line groups and the power line groups are arranged at intervals, wound on the outer side of the reinforced wire core, stranded along the reinforced wire core to form a cable core, and stranded into a multi-strand line group, so that the integral bending resistance and flexibility of the composite cable are improved. Preferably, the control cord set and the power cord set are each provided with 3 sets. Therefore, the control line group and the power line group can be just tangent, and the structure stability is higher.

The control line group plays a role in transmitting signals and sequentially comprises the following components from inside to outside: the composite material comprises aramid fibers 1, a first silicone rubber layer 2 arranged on the outer surface of the aramid fibers 1, a plurality of first copper conductors 3 which are uniformly distributed outside the first silicone rubber layer 2 and are suitable for control signal transmission, a fluoroplastic layer 4 used for coating the copper conductors, a first flame-retardant cloth belt 5 wound on the outer surface of the fluoroplastic layer 4, a shielding layer 6 arranged outside the flame-retardant cloth belt, and reinforced non-woven fabrics 7 arranged outside the shielding layer 6; the shielding layer 6 is a tinned copper wire braided shielding layer 6. The fluoroplastic layer 4 has the main properties of high strength, corrosion resistance and low friction coefficient; can absorb the torsion of the first flame-retardant cloth belt 5 and the tinned copper wire braided shielding layer 6 generated by torsion, can complete necessary offsetting movement, and improves the reliability and the safety because of reducing the friction force and the static electricity. Similarly, the silicone rubber layer has better high temperature resistance, and can ensure that the composite cable can stably run in a high-temperature environment.

The power cord set functions as power transmission, and includes: a second copper conductor 10 for power transmission, a second silicone rubber layer 11 disposed outside said second copper conductor 10. The silicone rubber layer has better high temperature resistance, and can ensure that the composite cable stably runs in a high-temperature environment.

The coating layer comprises: a second fire-retardant cloth belt 12 wound outside the control wire group and the power wire group, and a third silicon rubber layer 13 arranged outside the second fire-retardant cloth belt 12. Furthermore, the third silicone rubber layer 13 is provided with an anticorrosive coating 14 on the outside to protect the cable sheath from corrosion. For those skilled in the art, the corrosion resistant coating 14 may be, but is not limited to, polyethylene, polyvinyl chloride, and a thermal zinc coated bimetallic epoxy.

In order to facilitate understanding of the technical scheme of the high-temperature-resistant power control composite cable, the design principle is briefly explained: the silicone rubber filling strip 9 reinforced by the steel wire rope 8 is arranged in the center of the composite cable, so that the overall strength of the composite cable can be improved, and the occurrence of core breakage of a control wire core is reduced; the silicone rubber layer and the fluoroplastic layer 4 are arranged, so that the composite cable can stably run in a high-temperature environment; an anti-corrosion coating 14 is arranged on the outer surface of the composite cable to protect the cable sheath from being corroded.
