Embodiment 1

[0021] A high-strength fireproof and anti-interference cable includes a plurality of cable cores and outer protective sheaths, the cable cores are wrapped in the outer protective sheath by the outer protective sheath, the cable cores include an inner shielding layer and are arranged inside the inner shielding layer to form a ring Conductors distributed in a shape array, the outer surface of the conductor is also provided with an insulating layer, and the moisture-proof filler is filled between the insulating layer and the inner shielding layer; the surface of the cable core is also provided with protrusions and matching protrusions Groove, two adjacent cable cores are connected by engaging protrusions and grooves. The protrusion is set in the shape of an eagle's beak, so that after the protrusion is inserted into the groove, it can be locked to avoid slipping. In addition, the raised portion is made of elastic rubber material to facilitate the protrusion to be inserted into th...

Embodiment 2

[0023] On the basis of Embodiment 1, the outer protective sheath is also provided with a refractory mica tape, a copper wire braided shielding layer, and an outer sheath layer concentrically from the inside to the outside, and the outer protective sheath and the cable core are filled with Composite filling. Wherein, the composite filler adopts a mixture of glass fiber and polypropylene, so that the whole has a certain waterproof performance, and also enhances the overall heat resistance and corrosion resistance; the fire-resistant mica tape has good high-temperature fire resistance, It can effectively improve the fire-resistant stability of the cable and the integrity in high temperature and pyrotechnics; the copper wire braided shielding layer can effectively shield external interference signals and ensure the transmission speed and transmission quality of the cable; the outer sheath layer is made of polyvinyl chloride, which can Increase the compressive strength of the cable...

Abstract

The invention discloses a high-strength fireproof and anti-interference cable, which belongs to the technical field of cables. The aim of the invention is to provide a high-strength fireproof and anti-interference cable with a better structure and to solve the problem that the position structure between the cores of the cable in the prior art is unstable. The cable includes a plurality of cable cores and an outer protective sleeve. The cable cores are wrapped in the outer protective sleeve. Each cable core includes an inner shielding layer and conductors arranged in a circular array inside theinner shielding layer. An insulating layer is arranged on the outer surface of each conductor. The gaps between the insulating layers and the inner shielding layers are filled with damp-proof filler.A bump and a groove matching the bump are arranged on the surface of each inner shielding layer. Two adjacent inner shielding layers are connected by the bumps and the grooves clamped together. The outer protective sleeve is provided with a refractory mica belt, a copper wire braided shielding layer and an outer sheath layer which are sequentially and concentrically arranged from inside to outside. The gaps between the outer protective sleeve and the cable cores are filled with composite filler. The high-strength fireproof and anti-interference cable has the advantages of close position relationship between the cable cores, strong fireproof and anti-interference ability and high practicability.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a high-strength fireproof and anti-interference cable. Background technique [0002] Wire and cable are supporting products for power transmission and distribution, signal transmission or electromagnetic conversion. Although the wire and cable industry is only a supporting industry, it accounts for 1 / 4 of the output value of China's electrical industry. It has a wide variety of products and a wide range of applications, involving industries such as electric power, construction, communications, and manufacturing, and is closely related to various sectors of the national economy. However, during the use of cables, different environments require cables with better adaptability, such as cables that are more resistant to moisture in humid environments; cables that can withstand high temperatures are required in high-temperature environments. But in general, it is also very important ...
