電纜警示帶的探測常用的方法是電磁法。電纜警示帶內夾帶的金屬箔，在電磁場作用下的感應電流會產生二次場。可在地面上用探測儀器探測到，以確定電纜警示帶的位置。例如電磁法主動源法，信號強，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）。使用時發射機一端接被查蹤跡帶，另一端接地或接蹤跡帶另一端。探測儀通過探測蹤跡帶產生的磁感應強度的變化，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.

電纜警示帶的結構

Structure of cable warning tape

底膜與面膜、底膜與鋁箔結合牢固，并整體滾花成型。電纜警示帶印有醒目、性的警示語，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.
