Abstract

A double-layer high-shielding bundle coaxial cable belongs to the technical field of bundle coaxial cables. The double-layer high-shielding bundle coaxial cable comprises a cable body and a pluralityof flame-retardant cutting devices which are arranged on the cable body. The cable body comprises a plurality of sub-conductors, sub-shielding layers which are arranged outside each of the sub-conductors, a total shielding layer which is arranged outside the sub-conductors, a fireproof layer which is arranged outside the total shielding layer, and a protecting layer which is arranged outside the fireproof layer. The flame-retardant cutting device comprises a housing, a cutter which is arranged in the housing, an elastic member which is arranged at back part of the cutter, and a fusing member which is connected with the cutter and the inside wall of the housing. The edge of the cutter faces the cable body and is separated from the cable body by a certain distance. Two sides of the flame-retardant cutting device are provided with positioning devices. The positioning device comprises a spacing ring, an annular sliding trough which is arranged on the outside surface of the spacing ring, asliding ring which slidably sleeves the annular sliding trough, and a fixed member which is connected with the sliding ring. The double-layer high-shielding bundle coaxial cable has advantages of protecting the cable system, preventing fire propagation, and reducing loss.

Description

technical field [0001] The invention relates to the technical field of bundled coaxial cables, in particular to a double-layer high shielded bundled coaxial cable. Background technique [0002] In order to avoid or reduce the impact of fire in the existing bundled coaxial cables, a fireproof layer made of flame-retardant materials is generally added to the cable body. Although it can reduce the damage caused by fire to the cable to a certain extent, However, in the case of a fierce fire, its fireproof effect will be greatly weakened, and the outer layer material of the cable will still make the fire spread, causing unpredictable damage and loss to its surrounding environment. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a double-layer high-shielding bundled coaxial cable, which can not only protect the cable system, but also control the spread of fire to reduce losses. [0004...
