地埋示踪线:示踪线的生长已履历三代

泉源:/ 宣布时间:日期:2024-03-31 0

一代示踪线:是由铝箔和塑料薄膜的母体组成,铝箔主要是传输信号,母体是牢靠铝箔。这种示踪线弱点:铝箔强度很是低,纵然在生产,运输历程中也很容易断裂,辅设易损伤,同时铝箔的电阻很是大,有用探测距离和深度有限。

First generation tracer line: It is composed of a matrix of aluminum foil and plastic film. The aluminum foil is mainly used for transmitting signals, and the matrix is a fixed aluminum foil. The disadvantages of this tracer line are that the strength of the aluminum foil is very low, and it is easy to break even during production and transportation. The auxiliary equipment is easily damaged, and the resistance of the aluminum foil is very high, which limits the effective detection distance and depth.

二代示踪线:是由钢丝和塑料薄膜压制而成,该示踪线由钢丝为导体,电阻大,探测距离有限,难以知足现实需要。

Second generation tracer line: It is made by pressing steel wire and plastic film. The tracer line is made of steel wire as the conductor, with high resistance and limited detection distance, making it difficult to meet practical needs.

三代示踪线:是由铜包钢金属线芯和PE外;げ阕槌,外观成线状。以下以HX-13II示踪线为例

Third generation tracer wire: It is composed of copper clad steel metal wire core and PE outer protective layer, with a linear appearance. Taking the HX-13II tracer line as an example

在第三代示踪线还没有降生,二代产品又不可知足要求的情形下,电线成为示踪线的替换品,由于电线并不是针对PE管道示踪而设计的产品,其自己用于充当“示踪线”则有诸多缺限。

In the absence of third-generation tracer wires and the inability of second-generation products to meet the requirements, wires have become a substitute for tracer wires. However, since wires are not designed specifically for PE pipeline tracing, their use as "tracer wires" has many limitations.

本钱高:电线做为示踪线,其造价相对腾贵。

High cost: As a tracer wire, the cost of wires is relatively expensive.

抗侵蚀和抗老化差:电线的外外貌绝缘层是PVC,这种质料埋地后易老化,相对PE材质有所缺乏。

Poor corrosion resistance and aging resistance: The outer surface insulation layer of the wire is PVC, which is easy to age after being buried, and is insufficient compared with PE material.

抗拉力:电线金属芯是铜材质,抗拉力有局限性,在用于通例辅设及非开挖辅设时,断裂机率较高。

Tensile strength: The metal core of the wire is made of copper material, which has limitations in tensile strength. When used in conventional and non excavation auxiliary equipment, the probability of fracture is relatively high.
