Embodiment Construction

[0028] The anti-corrosion insulating steel strand proposed by the present invention is described in detail as follows in conjunction with the embodiment in the overhead line construction method:

[0029] The method of using anti-corrosion insulated steel strands in overhead communication lines proposed by the present invention is characterized in that anti-corrosion insulated steel strands are used to hang communication optical cables at the intersection of three wires, and ordinary steel strands are used to hang them in other areas. Communication optical cable; the anti-corrosion insulating steel strand is composed of an anti-corrosion insulating outer sheath and a steel strand sheathed in it. The outer sheath is made of a polymer composite material, and the wall of the outer sheath is The thickness is 1-2mm.

[0030] The invention also includes the use of anti-corrosion insulating steel strands in areas polluted by electrochemical corrosion.

[0031] The structures of the s...

Abstract

The present invention relates to a construction method adopting the corrosion protecting insulating cable in the overhead communication line, and the invention belongs to the technique field for protecting the overhead communication line. In the method the corrosion-protecting insulating cable is adopted at the three-line intersection for hanging the communication optical cable, and in other areathe common cable is adopted for hanging the optical cable. The corrosion-protecting insulating cable is obtained by assembling the corrosion-protecting insulating cable and the cable sleeved therein,and the oversheath is made of high-molecule composite material and the wall thickness of the oversheath is 1-2mm. The method reliably settles the hidden danger of disoperation of the three-line crossing to the communication line. Not only the construction method is safe, cheap and effective; but also the cable rust can be prevented in order to guarantee the design life of the overhead communication line.

Description

technical field [0001] The invention belongs to the technical field of overhead communication line protection, and in particular relates to an anti-corrosion insulating steel strand and a construction method for the overhead line. Background technique [0002] According to the current design standards for overhead communication lines, under normal circumstances, its service life should be more than 20 years. At present, the communication optical cables are suspended by overhead steel strands; but with the development of the national economy. For a long time to come, air pollution will be relatively serious. Whenever rainy or foggy days will cause greater galvanic corrosion to the steel strands of overhead communication lines, thus endangering the safety of the entire line. In areas with relatively developed industries, individual road sections such as: industrial areas, near chemical plants, and polluted rivers have been put into use, and the lines that have only been used...
