Embodiment Construction
[0007] The embodiment is described in detail in conjunction with the accompanying drawings, the direct buried cable protection tape, which includes a double-layer plastic tape 2, a communication wire 4 is provided in the interlayer of the plastic tape, a signal generator 1 is provided at one end of the communication wire, and the signal generator is installed on the user end, the other end of the communication wire is provided with a signal receiver 3, and the signal receiver is installed in the substation. The present invention is buried in the upper soil layer of the direct-buried cable when in use, 40-50 centimeters away from the direct-buried cable. In the case of cables, the protective belt of the directly buried cable will be dug out first, which will serve as a reminder and warning to those who dig by mistake. Workers may have the situation that the direct buried cables are dug by mistake, which is convenient for substation personnel to find in time. In this embodiment, ...

The invention discloses a direct buried cable protective band which is reasonable in structure and capable of preventing a direct buried cable from being mistakenly damaged. According to the technical scheme, the direct buried cable protective band comprises a double-layer plastic strip, wherein a communication wire is arranged in an interlayer of the plastic strip, one end of the communication wire is provided with a signal generator, and a signal receiver is arranged at the other end of the communication wire. The surface of the plastic strip is coated with fluorescent materials. The direct buried cable protective band is reasonable in structure and good in using effect, can effectively prevent the cable from being mistakenly dug, and guarantees safe use of the cable.
Description
Technical field: [0001] The invention relates to auxiliary equipment for power facilities, in particular to a direct-buried cable protection tape capable of preventing direct-buried cables from being damaged. Background technique: [0002] The current direct buried cables are becoming more and more popular, but because the direct buried cables are buried underground, the ground markings are limited. Directly buried cables cause damage, affect the normal transmission of electricity, bring many unnecessary hidden dangers to the normal operation of power facilities, and also bring safety hazards to construction personnel and equipment that accidentally dig cables. Invention content: [0003] The object of the present invention is to design a direct buried cable protective tape with reasonable structure and capable of avoiding the direct buried cable from being accidentally damaged. [0004] The technical solution of the present invention is the direct buried cable pro...
