Problems solved by technology

[0003] The power cables used in construction have very strict requirements on their strength and wear resistance. Due to the complex terrain of the construction site, the construction cables need to move frequently on the ground. Due to friction, the cables are easily damaged, which affects the actual use.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a high-strength wear-resistant cable for construction. Background technique [0002] At present, power cables are cables used to transmit and distribute electric energy. Power cables used in construction have high requirements on the flame retardancy, heat resistance and aging resistance of cables. Power cables are generally composed of conductor cores, insulating layers, shielding layers, and protective layers. The insulating layer is to electrically isolate the cores from the ground and cores of different phases to ensure power transmission. It is a power cable structure. An indispensable component, the performance of the insulation layer has a great impact on the overall performance of the cable, which is directly related to whether the cable operates normally. The insulating layer can be made of rubber material, commonly used rubber is natural-styrene-butadiene rubb...
