Problems solved by technology

[0002] Most of the existing security monitoring 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 single-core semi-foamed monitoring coaxial cable includes: a single-core inner conductor 1, a semi-foamed insulator 2 arranged outside the single-core 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] A plurality of sensing fibers 5 are evenly arranged in the semi-foamed insulator 2, which can detect whether the insulator is damaged, timely repair it, and reduce the occurrence of accidents.

[0012] The single-core inner conductor 1 is semi-foamed, and the material used per kilometer is 5.6kg, while the solid core is 11kg per kilometer. It is found in production that the material used for the semi-foamed cable is about half that of the solid core.

[0013] During the t...

Abstract

The invention discloses a single-core semi-foaming type monitoring coaxial cable which is low in material consumption. The cable comprises a single-core inner conductor, a semi-foaming insulator arranged on the outer side of the single-core inner conductor, a shielding layer arranged on the outer side of the semi-foaming insulator and a protection sleeve arranged on the outer side of the shielding layer. The cable is advantageous in that in a production process, semi-foaming processing is performed on the insulator; by use of the semi-foaming technology, raw and auxiliary materials can be greatly reduced; resources are saved; the call of the country for energy conservation and emission reduction is responded to; signal attenuation in the cable can be effectively controlled; signal transmission performance is good; whether the insulator is damaged can be detected; maintenance can be performed timely; and occurrence of accidents can be reduced.

Description

technical field [0001] The invention relates to a cable, in particular to a monitoring coaxial cable. Background technique [0002] Most of the existing security monitoring 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 single-core 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 single-core semi-foamed monitoring coaxial cable, comprising: a single-core inner conductor, a semi-foamed insulator arranged outside the single-core inner conductor and a semi-foamed ins...
