示踪线广受欢迎的特点

The popular characteristics of tracer line

示踪线具有防水性好、示踪速度快、防腐性强、拉力大等特点，被业界所看好，它是结合现有电线、电缆等地下非金属管道无法检测的产品的优缺点，继承和改进的新一代技术产品。

The tracer line 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.

与非金属管道一起铺设，使用检测设备进行点对点交换与示踪电缆的金属芯点信号，从而检测其在地下的准确位置，并能同时测量和确定非金属管道的埋深、方向和位置、管径的大小。

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.

示踪线产品的问世和不断研发，结合和地方政府各部门的相关要求，相信对今后我国地下管网建设将起到很好的推动作用。

The advent and continuous research and development of tracer line 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.

示踪线广受欢迎的测试过程

The popular testing process of tracer line

为保证示踪线的导电性、强度、耐腐蚀性和耐用性，一般建议选用截面积大于2.5mm的多股铜线，并尽量将示踪线保持在铺设时管的顶部。导线接头的绝缘层应在分支处剥去，将铜芯绞在一起几圈，然后在接头处用绝缘胶带包裹，以保持良好的导电性。

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 2.5mm, 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.

管道示踪线的线头被泥土或碎屑覆盖。为了降低探线不能出地的末端的接地电阻，需要采取良好的接地措施，剥去裸芯线的绝缘层30cm。强度较大的导体可以避免在施工过程中被拉断，导致无法检测定位。

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 30cm 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.

当导体直径远小于埋深且忽略地面介质和空气的介质变化时，示踪线可视为均质介质中的无限长线。

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