NDEC-301 Cable Path Detector

Product Introduction

        NDEC-301 Cable Route Detector (Pipeline Locator) is used for detecting, identifying, and measuring the burial depth of underground cable lines (de-energized/live) and metal pipelines, as well as locating faults in street lighting cables and buried lines. It can also be used for tracing underground live cables. With its superior performance and flexible detection methods, the device is widely used in power, telecommunications, water supply, heating, gas, petroleum, chemical, and urban public utilities sectors, making it an essential tool for construction, acceptance inspection, and pipeline network surveys.
        The product features a wide frequency range. Equipped with a high-power transmitter and an easy-to-operate digital receiver, it utilizes multi-frequency detection technology for convenient field operation. By selecting appropriate frequencies, it accurately locates underground pipelines, helping users quickly find buried telephone lines, optical cables, CATV, power lines, gas pipelines, and water supply/drainage pipes. The product is highly automated, enabling even non-professionals to achieve professional detection results, playing a positive role in improving pipeline management levels in related industries in China.
