The tracer wire is suitable for the rapid detection and positioning of underground non-metallic pipelines such as gas, tap water, drainage and sewage. Do you know the popular characteristics of the tracer wire and the test process?

The popular characteristics of tracer wire

The tracer wire has the characteristics of good waterproof, fast tracing speed, strong corrosion resistance, large tension and so on, and is favored by the industry. It is a new generation of technical products inherited and improved by combining the advantages and disadvantages of products that cannot be detected by existing wires, cables and other underground non-metallic pipelines.

It is laid together with the non-metallic pipeline, and the detection equipment is used to exchange point-to-point signals and trace the metal core of the cable, so as to detect its accurate position underground, and simultaneously measure and determine the buried depth, direction, position and diameter of the non-metallic pipeline.

The advent and continuous research and development of tracer wire products, combined with the relevant requirements of national and local government departments, are believed to play a good role in promoting the construction of underground pipe networks in China in the future.

The popular testing process of tracer wire

In order to ensure the conductivity, strength, corrosion resistance and durability of the tracer wire, it is generally recommended to select multi strand copper wire with a cross-sectional area greater than 2.5 mm, and try to keep the tracer wire on the top of the pipe when laying. The insulation layer of the conductor joint shall be stripped at the branch, the copper core shall be twisted together for several circles, and then the joint shall be wrapped with insulating tape to maintain good conductivity.

The end of the pipe trace line is covered with soil or debris. In order to reduce the grounding resistance of the end where the probe wire cannot go out of the ground, it is necessary to take good grounding measures and strip 30 cm of the insulation layer of the bare core wire. The conductor with high strength can avoid being broken during construction, which makes it impossible to detect and locate.

When the conductor diameter is much smaller than the buried depth and the medium changes of ground medium and air are ignored, the tracer wire can be regarded as an infinite line in homogeneous medium.
