地埋示踪线目前在国内PE管工程中占据主要地位，它的稳定性是示踪线的大亮点，下面小编来讲讲示踪线的形式与性能内容吧。

Buried trace line currently occupies a major position in domestic PE pipe engineering, and its stability is the highlight of the trace line. The following section will talk about the form and performance of the trace line.

1、钢丝塑料薄膜示踪线，是一种由钢线或其他金属丝与PE塑料薄膜压制而成，经常与警示带整合使用，钢丝直径在0.5mm?左右。

1. Steel wire plastic film tracing line is a kind of steel wire or other metal wire pressed with PE plastic film, which is often used in combination with warning tape. The diameter of steel wire is 0.5mm? about.

性能：由钢丝为导体，由于横截面积小造成不易连接，电阻大，探测距离有限只有十几米到几十米，实际施工中易断裂，电气有效连通性易被破坏，难以满足实际需要。

Performance: The steel wire is the conductor, which is difficult to connect due to its small cross-sectional area. The resistance is large, and the detection distance is limited to only tens to tens of meters. It is easy to break in actual construction, and the effective electrical connectivity is easy to be damaged, which is difficult to meet the actual needs.

2、电线示踪线，利用铜制或铝制电线缆为示踪线，截面积多采用2.5-4mm?。

2. The copper or aluminum wire and cable are used as the trace wire of the electric wire, and the sectional area is usually 2.5-4mm?.

性能：由于采用电线或电缆，其检测距离远、效果好，但造价相对昂贵。电线的外表面绝缘层是PVC，这种材料麦迪后易老化，相对PE材质有所不足，电线金属芯多是铜或铝材质，抗拉有局限性，在用于常规铺设及非开挖铺设时，断裂几率较高。

Performance: Due to the use of wires or cables, the detection distance is far and the effect is good, but the cost is relatively expensive. The insulation layer on the outer surface of the wire is PVC, which is easy to age after being made of McGrady. Compared with the PE material, it is insufficient. The metal core of the wire is mostly made of copper or aluminum, and its tensile strength is limited. When it is used for conventional laying and trenchless laying, the fracture probability is high.

3、专用示踪线，是由专用金属线芯（铜包钢）和PE外保护层组成，截面积多采用205-7mm?。

3. The special tracer wire is composed of special metal wire core (copper clad steel) and PE outer protective layer, with the sectional area of 205-7mm?.

性能：示踪线，采用PE作为外保护层，绝缘、防腐、防水、抗老化，芯层中的铜层适当增强导电性，提高电信号，通信科有效增加增强线体强度，导电性稍差但强度和力学性能很好。在欧美示踪线应用了20余年，具有较好的经济效应。目前国内多采用示踪线作为PE管的示踪线来使用。

Performance: The tracer line uses PE as the external protective layer, which is insulated, anti-corrosion, waterproof and anti-aging. The copper layer in the core layer properly enhances the conductivity and improves the electrical signal. The communication department effectively increases the strength of the line body. The conductivity is slightly poor, but the strength and mechanical properties are very good. The trace line has been applied in European and American countries for more than 20 years and has good economic effect. At present, the tracer line is mostly used as the tracer line of PE pipe in China.

示踪线的采购要注意其质量，目前尚未有明确的标准，这就需要在采购的时候注意。其次在工程施工中要提前测试示踪线的可行性，填埋后也要再次测试，避免返工。

Attention should be paid to the quality of the trace line when purchasing. At present, there is no clear standard, which requires attention when purchasing. Secondly, the feasibility of the trace line shall be tested in advance during the project construction, and it shall be tested again after the landfill to avoid rework.

示踪线容易遭受周边环境的影响，尽量避免在强弱电管道与接地体过近，以防造成测试不准确。为了确保施工质量可以采用双线路的方式保证其与稳定。关注我们http://www.binzhouhengtong.com带您了解更多更详细的事项！

The trace line is easy to be affected by the surrounding environment. Try to avoid being too close to the grounding body in the strong and weak current pipelines to prevent inaccurate testing. In order to ensure the construction quality, double track road can be used to ensure its safety and stability. Follow us http://www.binzhouhengtong.com Take you to know more and more details!
