示蹤線適用于燃?xì)?、自來水、排水、污水等地下非金屬管道的快速檢測和定位，那么您知道示蹤線廣受歡迎的特點以及測試過程是怎樣的嗎？

The tracer line 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 line and the test process?

示蹤線廣受歡迎的特點

The popular characteristics of tracer line

示蹤線具有防水性好、示蹤速度快、防腐性強、拉力大等特點，被業(yè)界所看好，它是結(jié)合現(xiàn)有電線、電纜等地下非金屬管道無法檢測的產(chǎn)品的優(yōu)缺點，繼承和改進(jìn)的新一代技術(shù)產(chǎn)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.

與非金屬管道一起鋪設(shè)，使用檢測設(shè)備進(jìn)行點對點交換與示蹤電纜的金屬芯點信號，從而檢測其在地下的準(zhǔn)確位置，并能同時測量和確定非金屬管道的埋深、方向和位置、管徑的大小。

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.

示蹤線產(chǎn)品的問世和不斷研發(fā)，結(jié)合和地方政府各部門的相關(guān)要求，相信對今后我國地下管網(wǎng)建設(shè)將起到很好的推動作用。

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.

示蹤線廣受歡迎的測試過程

The popular testing process of tracer line

為保證示蹤線的導(dǎo)電性、強度、耐腐蝕性和耐用性，一般建議選用截面積大于2.5mm的多股銅線，并盡量將示蹤線保持在鋪設(shè)時管的頂部。導(dǎo)線接頭的絕緣層應(yīng)在分支處剝?nèi)?，將銅芯絞在一起幾圈，然后在接頭處用絕緣膠帶包裹，以保持良好的導(dǎo)電性。

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.

管道示蹤線的線頭被泥土或碎屑覆蓋。為了降低探線不能出地的末端的接地電阻，需要采取良好的接地措施，剝?nèi)ヂ阈揪€的絕緣層30cm。強度較大的導(dǎo)體可以避免在施工過程中被拉斷，導(dǎo)致無法檢測定位。

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.

當(dāng)導(dǎo)體直徑遠(yuǎn)小于埋深且忽略地面介質(zhì)和空氣的介質(zhì)變化時，示蹤線可視為均質(zhì)介質(zhì)中的無限長線。

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.
