Abstract

The invention discloses a copper core low-voltage power cable with an armor structure, comprising an inner sheath, wherein the inner sheath has a plurality of copper core conductors arranged circumferentially, the intermediate position enclosed by the plurality of the copper core conductors is provided with a supporting core, the supporting core has radially extending spacers having the same number of the copper core conductors, the spacers are pasted around the copper core conductors to the other side and the another copper core conductor, supporting strips are disposed between each two copper core conductors, the inner sheath is externally wrapped with an aluminum alloy armor layer that is externally wrapped with an outer sheath, the cross section of the supporting strips is a triangle,one vertex angle thereof is connected to the spacers, three sides are all arc-shaped surface that open outward, and the sides of the spacers and the supporting strips are all coated with resin glue layers. The cable provided by the invention has strong mechanical strength and anti-extrusion ability, is not easy to be deformed, and has simple manufacturing process and high efficiency.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a copper core low-voltage power cable with an armored structure and a manufacturing method. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. According to the voltage level, it can be divided into medium and low voltage power cables (35 kV and below), high voltage cables (above 110 kV), extra high voltage cables (275-800 kV) and extra high voltage cables (1000 kV and above). Among them, low-volta...
