Embodiment Construction

[0013] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] Such as figure 1 As shown, an anti-crosstalk cable includes an outer insulating layer 2 and a filler layer 1 inside the insulating layer 2. The insulating layer 2 includes a first phlogopite tape, a composite refractory tape and a second phlogopite mica tape from outside to inside. The composite refractory belt is calendered from a mixture of glass fiber cloth and ceramizable silicone rubber. The setting of glass fiber cloth helps to improve the strength when the ceramizable silicone rubber exhibits ceramic characteristics, and it is also convenient for the composite refractory belt. Forming; the cross-sections of the insulating layer 2 and the filler layer 1 are both circular, and ...

Abstract

The invention discloses a crosstalk-resistant cable comprising an external insulating layer and a filler layer which is arranged in the insulating layer. At least one and more than one cable cores arranged between the insulating layer and the filler layer are arranged around the filler layer. Each cable core comprises a conductor layer, a first metal braided layer, a color tape and an insulator which are arranged from inside to outside. The external surface of the insulator of each cable core is provided with lubricant. Sensing fibers are distributed in the insulating layer. Each cable core is internally provided with the first metal braided layer so that the shielding effect between the cable cores can be realized and crosstalk can be reduced; and the sensing fibers can be used for judging the integrity of the insulating layer so that the problems that local insulator damage and shedding of the cable cannot be timely checked and accidents are liable to occur in the use process can be solved, the structure is simple and reliability is high and the cable has the comprehensive performance of copper and aluminum.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a cable. Background technique [0002] Existing cables are generally made of all-copper or all-aluminum. Since copper cables are superior to aluminum in oxidation resistance, welding performance and electrical conductivity, they are widely used in transmission cables with large currents. Expensive and high density, it is replaced by aluminum conductors under certain conditions of use. With the continuous development of technology, the complexity and diversification of cable use occasions, copper or aluminum conductors are also somewhat powerless in comprehensive use. [0003] At the same time, in the process of transportation or other use environments, the local insulator caused by the cable is damaged or falls off without immediate inspection, which is likely to cause accidents during use. At the same time, the inspection process requires manpower and increases labor ...
