Problems solved by technology

Most of the existing monitoring coaxial cables use solid-core monitoring cables. In actual use, the signal attenuation of solid-core monitoring cables is relatively large, the consumption of consumables is large, the cost of use is high, and resources are wasted. They cannot respond to the national call for energy conservation and emission reduction.

Embodiment Construction

[0009] The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0010] Such as figure 1 As shown, the multi-strand semi-foamed monitoring coaxial cable includes: a multi-strand inner conductor 1, a semi-foamed insulator 2 arranged outside the multi-strand inner conductor 1 and a shielding layer 3 arranged outside the semi-foamed insulator 2 and A protective sleeve 4 arranged outside the shielding layer 3 .

[0011] Several sensing fibers 5 are evenly arranged in the semi-foamed insulator 2 , and a flame-retardant layer 6 is arranged between the protective sheaths 4 outside the shielding layer 3 .

[0012] The above-mentioned multi-strand semi-foamed monitoring coaxial cable, in the production process, the insulator is semi-foamed, and the semi-foaming process can greatly reduce raw and auxiliary materials, save resources, respond to the national call for energy conservation and em...

Abstract

The invention discloses a multi-stranded semi-foamed monitoring coaxial cable with small consumable usage. The multi-stranded semi-foamed monitoring coaxial cable comprises a multi-stranded inner conductor, a semi-foamed insulator arranged at the outer side of the multi-stranded inner conductor, a shielding layer arranged at the outer side of the semi-foamed insulator and a protective sleeve arranged at the outer side of the shielding layer. The multi-stranded semi-foamed monitoring coaxial cable has the advantages that semi-foaming treatment is carried out on the insulator in the production process; the raw and auxiliary materials can be greatly reduced by using a semi-foaming technology; resources are saved; the multi-stranded semi-foamed monitoring coaxial cable responds to the national call of energy conservation and emissions reduction; signal attenuation in the cable can be effectively controlled; the signal transmission performance is good; the flame retarding effect is good; and whether the insulator is damaged or not can be detected and the insulator can be timely repaired, so that an accident is reduced.

Description

technical field [0001] The invention relates to a cable, in particular to a monitoring coaxial cable. Background technique [0002] Existing monitoring coaxial cables are widely used in video monitoring, radio communication, computer network and mobile communication to transmit video, audio and data signals, etc. Most of the existing monitoring coaxial cables use solid-core monitoring cables. In actual use, the signal attenuation of solid-core monitoring cables is large, the consumption of consumables is large, the cost of use is high, and resources are wasted. They cannot respond to the national call for energy conservation and emission reduction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-strand semi-foamed monitoring coaxial cable with a small amount of consumables. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a mul...
