为保证示踪线的导电性、强度、耐腐蚀和耐久性，一般宜选择截面积大于2.5毫米的多股铜质电线，铺设时尽量让示踪线保持在管道的顶部位置，在三通等分支处应将导线接头的绝缘层剥掉，把铜芯绞在一起数圈，然后用绝缘胶布裹好接头，以保持良好的导电性。

In order to ensure the conductivity, strength, corrosion resistance and durability of the tracer wire, multi strand copper wires with a cross-sectional area of more than 2.5 mm should be generally selected, and the tracer wire should be kept at the top of the pipe as far as possible during laying. The insulation layer of the conductor joint should be stripped off at the branch of the tee, and the copper core should be twisted together for several circles, and then the joint should be wrapped with insulating tape to maintain good conductivity.

示踪线应留有一定的线头余量，并避免导线头被泥土或杂物覆盖，为减少无法出地的示踪线末端的接地电阻，需采取剥掉绝缘层裸露芯线30cm的良好接地措施，对于采取定向钻方式铺设的PE管道，应选用强度更大的导线，以避免在施工中被拉断,导致无法探测定位；当导线直径远小于埋深并忽略地介质和空气的介质变化时，示踪线可视为均匀介质中的一条无限。

A certain amount of wire head allowance shall be reserved for the tracer wire, and the wire head shall not be covered by soil or debris. In order to reduce the grounding resistance at the end of the tracer wire that cannot go out of the ground, good grounding measures of stripping the insulation layer and exposing the core wire for 30cm shall be taken. For PE pipes laid by directional drilling, wires with greater strength shall be selected to avoid being broken during construction, resulting in the inability to detect and locate; When the diameter of the conductor is much smaller than the buried depth and the medium changes of the ground medium and air are ignored, the tracer line can be regarded as an infinite line in the uniform medium.

此外在自己动手接示踪线的时候要注意这些事项（请按照操作说明要求施工）：

In addition, pay attention to these matters when connecting the tracer line by yourself (please follow the operation instructions):

1、用剪刀剪开（分离）两条并联的示踪线时，应注意两条线是否均匀，被分开的两条示踪线表面要光滑，不能有凸台、尖角（非常重要），会影响连接器的防水性能。

1. When cutting (separating) two parallel trace lines with scissors, attention should be paid to whether the two lines are uniform. The surface of the separated two trace lines should be smooth without bosses and sharp corners (very important), which will affect the waterproof performance of the connector.

2、是否有金属线漏出，不能将外漏金属丝的示踪线埋地。

2. Whether there is metal wire leakage, the tracer line of the leaked metal wire cannot be buried.

3、在剥PE保护层时不要损伤金属线。

3. Do not damage the metal wire when peeling the PE protective layer.

4、接线柱连接好接头后，应用力拉动接头两端的示踪线，检查接头的连接强度。

4. After the terminal is connected to the joint, pull the tracer wire at both ends of the joint with force to check the connection strength of the joint.

5、不要忘记对防腐/防水连接器的紧固；出地后的示踪线头部位，应用防水胶布和热缩管封紧。

5. Don't forget to fasten the anti-corrosion / waterproof connector; After leaving the ground, the tracer thread head shall be sealed with waterproof tape and heat shrinkable pipe.

6、管道示踪线应在每个阀门井处设置接头便于检测，每五百米必须设置一个检测井。

6. The pipeline tracing line shall be provided with joints at each valve well for inspection, and an inspection well must be set every 500 meters.
