Underground Cable Detector

Chapter 1: Introduction

1.1 Significance of R&D

Our company has a history of over three decades in the research and production of underground pipeline detectors. While developing these detectors, we have also been committed to providing services and research in metal pipeline routing and fault testing technologies for many years, solving numerous complex issues for our clients and earning their trust and support. By bringing field problems back for targeted research, we have finally developed the much-anticipated, domestically unique "Integrated Metal Pipeline Detector." The successful development of this product has resolved the long-standing issue of power supply departments struggling to find paths while maintaining power; it has also addressed the difficulty in accurately tracing the paths of faulty pipelines; and it has opened up a new field for metal pipeline routing, breaking the foreign product monopoly in China.

Scope of Application 1.2

Since the product was launched into the market, its powerful functions and superior performance have been widely used in urban power supply bureaus, county power companies, railway power supply sections, large and medium-sized enterprises (oil, chemical, coal, power plants, steel mills), schools and colleges, property management communities, city street lighting, highways, and communication maintenance departments. With our robust technical support, the product plays a crucial role in rapid repairs and quick location of underground pipelines for power supply and consumption departments.

1.3 Important Reminder

The instrument, though powerful in function and superior in performance, remains a tool—a tool辅助ing humans in solving problems. It cannot directly inform the exact location of the circuit, but the operator can easily make judgments and conclusions based on the various information reflected by the instrument.

The company is committed to continuous improvement and enhancement of our products, consistently introducing new offerings that are technologically advanced, performance superior, and feature-rich. We aim to provide a solid material foundation and robust technical support in the fields of metal pipeline monitoring and testing. We also welcome users to offer valuable feedback.

To ensure safe and smooth operation of this instrument and to fully utilize its functions, please carefully read the user manual before using the device.

Chapter II: Instrument Introduction

2.1 Working Principle

This instrument is a high-tech product designed based on the reflection principle of electromagnetic waves during transmission and the principle of electromagnetic induction, integrating digital filtering, wireless reception, and software control.

Electromagnetic Induction: Its basic working principle is that the transmitter generates electrical and magnetic waves, which are then transmitted to the underground pipeline through various transmission connections. Once the pipeline detects the electromagnetic waves, an induced current is generated on the cable surface. This induced current propagates along the metal cable. During its propagation, the current also radiates electromagnetic waves back towards the ground through the cable. When the underground pipeline testing instrument's receiver detects the electromagnetic wave signal on the ground, it receives the signal directly above the underground pipeline. The variations in the received signal strength can then be used to determine the location and direction of the underground pipeline.
