電纜警示帶的探測(cè)常用的方法是電磁法。電纜警示帶內(nèi)夾帶的金屬箔，在電磁場(chǎng)作用下的感應(yīng)電流會(huì)產(chǎn)生二次場(chǎng)?？稍诘孛嫔嫌锰綔y(cè)儀器探測(cè)到，以確定電纜警示帶的位置。例如電磁法主動(dòng)源法，信號(hào)強(qiáng)，定位、定深的精度高，不受臨近其他管道干擾（被查電纜警示帶需有露出點(diǎn)）。使用時(shí)發(fā)射機(jī)一端接被查蹤跡帶，另一端接地或接蹤跡帶另一端。探測(cè)儀通過(guò)探測(cè)蹤跡帶產(chǎn)生的磁感應(yīng)強(qiáng)度的變化，確定蹤跡帶的空間位置。

The common method for detecting cable warning tape is electromagnetic method. The induced current of the metal foil carried in the cable warning belt under the action of electromagnetic field will produce a secondary field. It can be detected on the ground with a detection instrument to determine the position of the cable warning tape. For example, the active source method of electromagnetic method has strong signal, high accuracy of positioning and depth determination, and is not interfered by other nearby pipelines (the detected cable warning tape needs to be exposed). When in use, one end of the transmitter is connected to the detected track band, and the other end is grounded or connected to the other end of the track band. The detector determines the spatial position of the track belt by detecting the change of magnetic induction intensity generated by the track belt.

電纜警示帶的結(jié)構(gòu)

Structure of cable warning tape

底膜與面膜、底膜與鋁箔結(jié)合牢固，并整體滾花成型。電纜警示帶印有醒目、性的警示語(yǔ)，不掉色、不褪色。

The bottom film and facial mask, and the bottom film and aluminum foil are firmly combined and knurled as a whole. The cable warning tape shall be printed with eye-catching and permanent warning words, which shall not fade or fade.
