Energy-saving conductor and preparation method thereof

Abstract

The invention discloses an energy-saving conductor, which comprises a circular wire non-compression twisting unit and a special-shaped wire twisting unit, wherein the special-shaped wire twisting unitsurrounds the outer side of the circular wire non-compression twisting unit. The interior of the conductor adopts a circular wire non-compression twisting structure, the exterior of the conductor adopts an energy-saving conductor structure of a special-shaped wire twisting structure, additional resistance of compacted conductor cold drawing processing can be effectively avoided through a conductor mixed twisting technology, the transmission efficiency of the conductor is improved, and meanwhile, through an external special-shaped wire twisting technology, the twisting outer diameter of the conductor is effectively reduced, and the cable material consumption is saved; moreover, the compact arrangement of adjacent single wires of the outer-layer conductor is effectively improved, the electric field distribution of the cable is uniform, and the overall quality of the cable is improved.

Description

Technical field [0001] The present invention relates to the technical field of wire and cable, and more particularly to an energy saving conductor and a preparation method thereof. Background technique [0002] In recent years, with the advancement of urban planning and construction, the demand for distribution cable is getting bigger and bigger, how to fully, and how to use cable transmission capacity, how to effectively improve cable transmission efficiency has always been an important topic of the cable industry. [0003] Most of the cable conductors use a circular tight conductive conductor structure or a circular non-tight conductor structure, wherein the circular pressurized conductor has increased additional resistance due to cold processing of processing, and the surface of the circular non-tight conductor is not flat, compact. There is a larger gap, the conductor shield is easy to fall into the insulating formation interface protrusion, resulting in a defect such as elec...

AI Technical Summary

Problems solved by technology

[0003] Most of the cable conductors adopt circular compacted conductor structure or circular non-compressed conductor structure, in which the circular compacted conductor has an increase in additional resistance due to cold working during processing; the surface of the circular non-compacted conductor is uneven and compact, There are large gaps, and the conductor shield is easy to sink into the insulation to form interface protrusions, resulting in defects such as electric field concentration, and the outer diameter of the conductor is too large, and the material consumption is large, resulting in unnecessary waste
