Embodiment Construction

[0011] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of an anti-extrusion composite cable proposed by the present invention.

[0012] refer to figure 1 , an anti-extrusion composite cable proposed by the present invention includes a buffer space 1 located at the core of the cable. On any cross-section, the buffer space 1 is surrounded by four sequentially connected curves that bend away from the center of the cable. Each curve A communication wire 2 is provided at the corresponding position, and a reinforcing rope 3 is arranged in the void space formed by adjacent communication wires 2. The buffer space 1, the communication wire 2 and the reinforcing rope 3 are filled with a flexible material to form a whole, and the outer circumference of the flexible material is arranged in sequence. There are a shielding layer 5, an insulating layer 6, a water-blocking layer 7 and a protective jacket 8. In the insulating layer 6, there are three power wires 4 re...

Abstract

The invention discloses an extrusion-resistant composite cable. The extrusion-resistant composite cable comprises a buffering space located in the center of the cable, wherein on any one section, the buffering space is defined by four curves, the four curves are sequentially connected and bent in the direction far away from the center of the cable, the corresponding position of each curve is provided with a communication conductive wire, a reinforcing rope is arranged in a hole space formed by every two adjacent communication conductive wires, the buffering space, the communication conductive wires and the reinforcing ropes are integrated because space among the buffering space, the communication conductive wires and the reinforcing ropes is filled with flexible materials, the peripheries of the flexible materials are sequentially provided with a shielding layer, an insulating layer, a water-proof layer and a protecting sheath, and three electric lines serving as a live line, a zero line and a ground line are arranged inside the insulating layer; the communication conductive wires are symmetrically distributed with respect to the central axis of the cable, and the included angle between the connection line of one communication conductive wire and the geometric center of the cable and the connection line of another adjacent communication conductive wire and the geometric center of the cable is 90 degrees on any cross section of the cable. The extrusion-resistant composite cable is compact in structure and high in extrusion-resistant ability.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an anti-extrusion composite cable. Background technique [0002] With the rapid improvement of human productivity, power consumption is also increasing day by day, and the increase in power consumption has promoted the rapid development of power facility construction. As an important part of the construction of power facilities, traditionally, single power cables and communication wires are gradually unable to meet the requirements for the use of cables, and cables are developing in the direction of composite and comprehensive. In the prior art, composite cables with both conductive and communication functions have the disadvantages of large volume, insufficient extrusion resistance, and easy damage. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes an anti-extrusion composite cable, which re...
