Problems solved by technology

[0002] With the rapid development of the country's economy, cables are developing in the direction of integration and generalization, and single power cables and communication cables are gradually unable to meet market demand.
The existing composite cables mainly simply add optical fiber to the power cable, which is relatively simple, and the increasingly complex use environment puts forward higher requirements for the comprehensive performance of composite cables
Composite cables in the prior art still have defects such as insufficient reliability and bulky structure

Embodiment Construction

[0010] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a composite cable proposed by the present invention.

[0011] refer to figure 1 , a composite cable proposed by the present invention, which includes a central support layer 1, a power conductor area 2 located on the periphery of the central support layer 1, a communication conductor area 6 located on the periphery of the power conductor area 2, and a protective jacket 7 from the inside to the outside. The support layer 1 includes steel wires 11 and fiber wires 12 wound on the surface of the steel wires 11. The power conductor area 2 is a three-layer structure formed by winding insulated wire cores outside the central support layer 1 in sequence; The first power conductor layer composed of one core 21, the second power conductor layer composed of the second core 22, the third power conductor layer composed of the third core 23, the first core 21, the second core 22, the second core The specif...

Abstract

The invention discloses a composite type cable which composite a center supporting layer, an electric conductor area, a communication conductor area and a protection coat from inside to outside in sequence, the center supporting layer comprises a steel wire and fiber wires winded on the surface of the steel wire, and the electric conductor area is a three-layer structure which is formed by winding insulated wire cores outside the center supporting layer sequentially; the specification and winding direction of a first wire core, the specification and winding direction of a second wire core and the specification and winding direction of a third wire core are different from each other, the electric conductor area is separated from the center supporting layer and the communication conductor area through an insulated braiding sleeve, and a first electric conductor layer, a second electric conductor layer and a third electric conductor layer are separated with one another through an insulation belt in a wrapped mode; a plurality of supporting frames are arranged in the communication conductor area, the supporting frames are arch-shaped structures on the cross-section of the cable, the communication conductor area is divided into three communication conductor spaces and heat dissipation space by the supporting frames, and a communication conductor is arranged in each communication conductor space. The composite type cable is simple in structure and strong in reliability.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a composite cable. Background technique [0002] With the rapid development of the national economy, cables are developing in the direction of integration and generalization, and a single power cable and communication cable cannot meet market demand gradually. The existing composite cables mainly simply add optical fiber to the power cable, which is relatively simple, but the increasingly complex use environment puts forward higher requirements for the comprehensive performance of composite cables. The composite cable in the prior art also has defects such as insufficient reliability and bulky structure. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a composite cable with simple structure and high reliability. [0004] A composite cable proposed by the present invention includes a centra...
