Embodiment Construction

[0015] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of an anti-extrusion armored power transmission cable proposed by the present invention.

[0016] refer to figure 1 , an anti-extrusion armored power transmission cable proposed by the present invention, comprising: a cable core, a first wrapping layer 3, an armor layer, a second wrapping layer 5, and a sheath layer 6;

[0017] The cable core includes a plurality of conductors 1 and a plurality of support strips 2, and the plurality of support strips 2 are vertically arranged in parallel and distributed along the circumference of the cable core. Arrangement of strip 2, each conductor 1 is located on the side of the adjacent support strip 2 away from the cable core axis and each conductor 1 is against the side walls of two adjacent support strips 2, and each conductor 1 is adjacent to two adjacent support strips 2 The side walls of the wires 1 are against each other, and each wire 1 includes a co...

Abstract

The invention discloses an anti-extrusion armoured power transmission cable. Multiple support strips are arranged in a parallel and longitudinal way and are distributed along the periphery of a cable core. Multiple conductive wires are arranged around all support strips. Each of the conductive wires is at one side of two adjacent support strips far from a cable core axis and each of the conductive wires and the side walls of the two adjacent support strips are in mutual abutment. Multiple armoured units are distributed along the circumference at the outer circumference of the cable core. Each of the armoured units has an elastic core body and an armoured steel wire wound around the outer circumference of the elastic core body. Through the above anti-extrusion armoured power transmission cable with optimization design, the structural design is reasonable, through arranging the support strips in the cable core, the conductive wires in the cable core are supported, a deformation space is provided for the conductive wires, an armoured layer formed by connecting multiple armoured units is arranged at the outer circumference of the cable core. When the cable is subjected to an external force, the steel wires plays a rigid protective effect, when the steel wires are deformed, the elastic core body is deformed, and thus the cable core is effectively protected from the outside.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an anti-extrusion armored power transmission cable. Background technique [0002] In metallurgy, electric power, petrochemical and other working environments that have special requirements for cables such as mobile anti-corrosion, cables are more likely to be squeezed by the outside after installation, especially in the process of anti-extrusion, the wires in the cable core are easily deformed or even broken. , can not guarantee the smooth transmission of power and communication, resulting in huge economic losses. Therefore, the outer circumference of conventional extrusion-resistant cables is provided with steel tape armor or braided armor. However, the conventional metal armor structure has a rigid structure, resulting in poor flexibility of the cable, and the cable core will still be damaged when it is deformed by an external force. Contents of the invention [0003] In ord...
