Problems solved by technology

[0002] Existing power cables do not have the functions of energy saving and efficiency enhancement and signal transmission. Therefore, for those that need to have the functions of power transmission and transmission of photoelectric signals, they require high conductivity, light weight, low cost, energy saving and environmental protection, corrosion resistance, and creep resistance. For the applicable occasions that are flexible, anti-fatigue, flexible, and flame-retardant, it is necessary to lay power cables and optical cables with the above properties at the same time. In other words, it exacerbated the congestion of pipeline laying, and correspondingly caused a lot of waste of funds

Abstract

A multi-core electrotechnical cable is disclosed. The cable comprises an iron-based alloy core material, an aluminium-based alloy core material and a copper-based alloy core material, wherein the exteriors of the three core materials are coated with dampproof layers to form three independent conductive core blanks; the three conductive core blanks are coated with filling materials to form a whole body; the exterior of the filling material is coated with an aluminium alloy metal wire shielding net; a light fiber weaving net is arranged on the exterior of the aluminium alloy metal wire shielding net; and the exterior of the light weaving net is coated with a cable material layer. The aluminium alloy metal wire shielding net has a shielding effect and the light weaving net can ensure the flexibility and strength of the cable.
