Low voltage power cable and production method thereof

Abstract

The invention discloses a low-voltage power cable and a production method thereof. The production method comprises the following steps: A. drawing and annealing an electrical round copper rod to obtain a solid conductor; B. drawing the electrical round copper wire; C. The electrical round copper wire after wire drawing is welded and twisted, and twisted into a conductor; D, the conductor obtained in step A and the conductor obtained in step C are wound together to form a cable conductor; E, the cable conductor is insulated Extruding and cross-linking into cables; F. Extruding or wrapping the formed cables for inner sheathing, and then armoring. In the present invention, the electrical round copper rod is wire-drawn to obtain a solid conductor, and at the same time, the electrical round copper wire is wire-drawn, and the electrical round copper wire after wire-drawing is welded and twisted, and twisted into a conductor. The cores are drawn separately, which effectively improves the overall strength and tensile capacity of the cable, which is in line with the interests of the enterprise itself.

Description

technical field [0001] The invention relates to the technical field of low-voltage power cables, in particular to a low-voltage power cable and a production method thereof. Background technique [0002] Electricity is an energy powered by electric energy. It was invented in the 1870s. The invention and application of electric power set off the second industrialization climax and became one of the three scientific and technological revolutions in the world since the eighteenth century in human history. It has changed people's lives. The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. , it converts the primary energy of nature into electricity through mechanical energy devices, and then supplies the electricity to various...
