地埋示蹤線目前在國(guó)內(nèi)PE管工程中占據(jù)主要地位，它的穩(wěn)定性是示蹤線的大亮點(diǎn)，下面小編來(lái)講講示蹤線的形式與性能內(nèi)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、鋼絲塑料薄膜示蹤線，是一種由鋼線或其他金屬絲與PE塑料薄膜壓制而成，經(jīng)常與警示帶整合使用，鋼絲直徑在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：由鋼絲為導(dǎo)體，由于橫截面積小造成不易連接，電阻大，探測(cè)距離有限只有十幾米到幾十米，實(shí)際施工中易斷裂，電氣有效連通性易被破壞，難以滿足實(shí)際需要。

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、電線示蹤線，利用銅制或鋁制電線纜為示蹤線，截面積多采用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：由于采用電線或電纜，其檢測(cè)距離遠(yuǎn)、效果好，但造價(jià)相對(duì)昂貴。電線的外表面絕緣層是PVC，這種材料麥迪后易老化，相對(duì)PE材質(zhì)有所不足，電線金屬芯多是銅或鋁材質(zhì)，抗拉有局限性，在用于常規(guī)鋪設(shè)及非開(kāi)挖鋪設(shè)時(shí)，斷裂幾率較高。

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、專用示蹤線，是由專用金屬線芯（銅包鋼）和PE外保護(hù)層組成，截面積多采用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：示蹤線，采用PE作為外保護(hù)層，絕緣、防腐、防水、抗老化，芯層中的銅層適當(dāng)增強(qiáng)導(dǎo)電性，提高電信號(hào)，通信科有效增加增強(qiáng)線體強(qiáng)度，導(dǎo)電性稍差但強(qiáng)度和力學(xué)性能很好。在歐美示蹤線應(yīng)用了20余年，具有較好的經(jīng)濟(jì)效應(yīng)。目前國(guó)內(nèi)多采用示蹤線作為PE管的示蹤線來(lái)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.

示蹤線的采購(gòu)要注意其質(zhì)量，目前尚未有明確的標(biāo)準(zhǔn)，這就需要在采購(gòu)的時(shí)候注意。其次在工程施工中要提前測(cè)試示蹤線的可行性，填埋后也要再次測(cè)試，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.

示蹤線容易遭受周邊環(huán)境的影響，盡量避免在強(qiáng)弱電管道與接地體過(guò)近，以防造成測(cè)試不準(zhǔn)確。為了確保施工質(zhì)量可以采用雙線路的方式保證其與穩(wěn)定。關(guān)注我們http://m.scnu-graduate.com帶您了解更多更詳細(xì)的事項(xiàng)！

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://m.scnu-graduate.com Take you to know more and more details!
