Carbon fiber copper core alloy wire spiral wrapping cable

Abstract

The invention discloses a carbon fiber copper core alloy wire spirally-wrapping cable including a conductor and an insulation layer. The insulation layer wraps the conductor. The conductor includes an inner core and two alloy wire layers. The inner core is composed of a carbon fiber core wire in the center and copper leads surrounding the carbon fiber core wire. The two alloy wire layers are formed by wrapping the inner core with a plurality of alloy wires in a spiral manner. Materials of the two alloy wire layers are the same and the spiral directions of the two alloy wire layers outside the inner core are the same. The spiral angels of climb of the two alloy wire layers are in a range between 25 degrees and 45 degrees. According to the invention, the carbon fiber copper core alloy wire spiral wrapping cable is high in tensile strength, good in ductility, low in DC resistance, good in electric conductivity, low in line loss and comparatively low in sag.

Description

Technical field [0001] The invention relates to the technical field of wires and cables, in particular to a carbon fiber copper core alloy wire spirally wrapped cable. Background technique [0002] In the prior art, copper-core steel stranded wire is a commonly used cable in China, and its stranded wire is galvanized steel wire. This kind of ordinary wire has large sag, line loss, and heavy weight of galvanized steel wire. As a result, the cost of the required infrastructure facilities has increased; in the process of rebuilding the old line, the method of increasing the cross section is used to achieve the purpose of increasing the capacity. It is necessary to replace the height and span of the tower, and the construction cost has doubled. Summary of the invention [0003] Aiming at the problems existing in the prior art, the present invention proposes a carbon fiber copper core alloy wire spirally wrapped cable. [0004] A carbon fiber copper core alloy wire spirally wrapped cabl...

Problems solved by technology

[0002] In the prior art, the copper core steel strand is the cable commonly used in China at present, and its strand is galvanized steel wire. This leads to an increase in the cost of the required infrastructure facilities; in the process of rebuilding the old line, the method of increasing the cross-section to achieve the purpose of increasing the capacity is bound to change the height and span of the tower, and the construction cost will increase exponentially
