Problems solved by technology

[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 inadequate in comprehensive use
[0003] At the same time, in the process of transportation or other use environments, the local insulator damage and fall off caused by the cable are not checked out immediately, which is easy to cause accidents during use, and at the same time, it takes manpower and increases labor costs during the detection process
In addition, the anti-interference performance is poor, and there is often a slight crosstalk between adjacent cable cores

Embodiment Construction

[0016] 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.

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] Such as Figure 1~Figure 2 As shown, an anti-seismic and anti-jamming cable includes an external insulating layer 2, and the insulating layer 2 sequentially includes a first phlogopite tape, a composite fire-resistant tape and a second phlogopite mica tape from the outside to the inside, and the composite fire-resistant tape is made of glass fiber cloth It is calendered with a mixture of 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 molding of composite refractory belts; Capsaicin anti-bite layer, the insulating layer 2 is distributed...

Abstract

The invention discloses an anti-vibration and anti-interference cable comprising an external insulating layer. A fireproof isolation layer, a thin aluminum powder layer, a metal protective layer and a silicon rubber internal sheath are arranged in the internal side of the insulating layer in turn. The silicon rubber internal sheath is internally provided with an aperture of which the cross section is circular. The aperture is internally provided with a "cross"-shaped silicon rubber compression resistant strip. The positions of the four corners of the silicon rubber compression resistant strip are provided with conductor cavities. Each conductor cavity is internally provided with a cable core. The cable core is provided with a copper aluminum double conductor layer, a copper plastic composite tape, an insulating isolation layer and an external shielding layer which are arranged from inside to outside. The middle position of the silicon rubber compression resistant strip is provided with a compression-resistant cavity. The gaps of the positions of the four corners of the silicon rubber compression resistant strip are provided with extruding strips which are simultaneously contacted with the silicon rubber internal sheath and the silicon rubber compression resistant strip. Each cable core is composed of the copper aluminum double conductor layer, the copper plastic composite tape, the insulating isolation layer and the external shielding layer which are arranged from inside to outside through twisting. Electromagnetic interference between the cable cores of the same cable can be prevented by the copper plastic composite tape and the external shielding layer so that the shielding effect between the cable cores can be realized. Besides, crosstalk between the cables can be effectively shielded by the metal protective layer so that crosstalk can be reduced.

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 ...
