Embodiment Construction

[0012] In order to better understand the technical solution of the present invention, it will be described in detail below through specific embodiments in conjunction with the accompanying drawings:

[0013] see figure 1 , the sheathed copper-clad steel telephone lead-in wire of the embodiment of the present invention comprises two copper-clad steel conductors 1, and black polyvinyl chloride 2 coated on the outside of the copper-clad steel conductors 1, and the black polyvinyl chloride 2 is Horizontal B-shape. Such a structure saves materials and costs.

[0014] The diameter of the copper-clad steel wire 1 is 0.96-1.05mm. Copper-clad steel conductor 1 is copper-clad steel coated by mechanical extrusion, the cost is lower than that of pure copper, and the transmission performance is the same. The steel inside is also high-strength steel, so that the copper-clad steel conductor has the characteristics of high strength. The copper is not easy to oxidize and has strong stabilit...

Abstract

The invention discloses a coated copper-clad steel telephone lead which comprises two copper-clad steels and black polyvinyl chloride coated at the outer surfaces of the copper-clad steels, wherein the black polyvinyl chloride is of a horizontal B shape; and the copper-clad steels are subjected to mechanical extrusion cladding and have the diameter of 0.9-1.05mm. The coated copper-clad steel telephone lead has the beneficial effects that the copper-clad steels produced by a high-intensity coating process are adopted so that the coated copper-clad steel telephone lead is stable in performance, less prone to oxidation corrosion and strong in resistance, can be used under harsh environments, can adapt to long-span remote transmission and is long in service life and low in cost.

Description

technical field [0001] The invention relates to a sheathed copper-clad steel telephone lead-in wire. Background technique [0002] At present, domestic and user telephone lead-in wires generally use galvanized iron wires, and generally have a parallel structure. The disadvantages are that they are easy to oxidize, and the cost is high, the performance is unstable, and the service life is not long. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a sheathed copper-clad steel telephone lead-in wire with simple structure, good transmission performance, strong stability and long service life. [0004] The technical scheme for realizing the above-mentioned purpose is: [0005] A sheathed copper-clad steel telephone lead-in wire comprises two copper-clad steel conductors and black polyvinyl chloride sheathed on the outside of the copper-clad steel conductors, the black polyvinyl chloride being ho...
