Problems solved by technology

Now the industry has developed a new conductor tube, which wraps the copper strip on the outside of the aluminum tube by sub-arc welding to form a copper-clad aluminum tube, which objectively has the advantages of light weight and low cost, and is convenient for network engineering construction. There are full-length welds distributed on the aluminum tube, so its communication effect is affected to a certain extent

Abstract

The invention provides a processing method for a conductor pipe in an improved radio frequency cable. The conductor pipe made by the method is of low dead weight, easy to construct and of low cost, can efficiently reduce the cost of the industry of cable and end users, and is of good communication effect. The invention is characterized in that, the method comprises the following procedures: de-oiling, cleaning, polishing by nitric acid, soaking zinc, de-zincing by nitric acid, soaking zinc, preparing pyrophosphate, plating copper, plating bright copper, passivating, cleaning with heated de-ionized water and drying.

Description

(1) Technical field [0001] The invention relates to the technical field of main conductor material processing for communication cables, wireless communication and monitoring network digital signal transmission, in particular to an improved method for processing inner conductor tubes of radio frequency cables. (two) background technology: [0002] At present, all pure copper inner conductor tubes are used in the cable industry. Copper is a globally scarce resource. Since copper is larger than aluminum and the price is high, cables processed with pure copper inner conductors are heavy in weight and high in cost, resulting in high costs for wireless communication and network engineering. The national annual usage reaches millions of tons, resulting in a huge consumption of copper resources. Now the industry has developed a new conductor tube, which wraps the copper strip on the outside of the aluminum tube by sub-arc welding to form a copper-clad aluminum tube, which objectiv...
