Embodiment Construction
[0031] The invention will be further described in detail below in conjunction with the drawings.
[0032] The reference signs in the drawings include the core 1, the insulating layer 2, the shielding layer 3, the protective layer 4, the air channel 5, and the air pressure sensor 6.
[0033] Such as figure 1 with figure 2 As shown, the anti-theft wire and cable in this embodiment includes a core 1, an insulating layer 2, a shielding layer 3, and a protective layer 4; the outer core 1 is provided with an insulating layer 2, a shielding layer 3, and a protective layer 4 in sequence;
[0034] It also includes airway 5, air pressure detection unit, field controller unit and communication unit;
[0035] The air passages 5 are arranged in the protective layer 4 along a direction parallel to the axial direction of the wire core 1. In this embodiment, the four air passages 5 are evenly distributed along the circumferential direction of the wire core 1. The air passages 5 are uniformly divide...

The invention discloses an antitheft type wire and cable, including a cable core, an insulating layer, a shielding layer and a protective layer, and also including an air passage, an air pressure detection unit, field controller units and a communication unit. The air passage is arranged in the protective layer along a direction parallel to an axial direction of the cable core, two ends are closedand filled with gas, a value is preset for air pressure, and the preset value is larger than one atmospheric pressure; a plurality of air pressure detection units are arranged in the air passage equidistantly; digital signal output ends of the air pressure detection units are electrically connected with the field controller units; and the field controller units are used for judging whether air pressure currently detected by each air pressure detection unit is higher than the preset value, and if the air pressure is smaller than the preset value, the serial number of the air pressure detectionunit, current time and alarm information are sent through the communication unit to an upper computer which stores the specific position of each air pressure detection unit. The technical problem inthe prior art that alarm means can be evaded by insulation measures is solved.
Description
Technical field [0001] The invention relates to an anti-theft wire and cable, which belongs to the technical field of high-voltage power transmission. Background technique [0002] With the rapid development of the national economy, the amount and scope of use of wires and cables as the aorta of the national economy are increasing. Wires and cables are cables used to transmit and distribute electrical energy. It is often used in urban underground power grids, lead-out lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines that cross rivers and seas. In power lines, the proportion of wires and cables is gradually increasing. Wires and cables are cable products used to transmit and distribute high-power electrical energy in the main line of the power system, including 1-500KV and various insulated wires and cables of various voltage levels. [0003] Wire and cable can be divided into two parts: core and protective lay...
