Polyvinyl chloride insulation and sheath flat power cable

Abstract

The invention discloses a polyvinyl chloride insulation and sheath flat power cable, and relates to the technical field of power cables, wherein the power cable comprises a tensile core, a shielding layer, a polyvinyl chloride sheath and a lower buckling cover, wherein the outer side of the tensile core is provided with a bare copper conductor, and the outer side of the bare copper conductor is wrapped with a polyvinyl chloride insulation layer. Through the anti-skid layers arranged on the inner walls of the upper buckling cover and the lower buckling cover, the friction force between the upper buckling cover and the polyvinyl chloride sheath can be effectively improved, so that the firmness and stability of the upper buckling cover and the lower buckling cover mounted on the outer side of the polyvinyl chloride sheath are ensured, and the loosening condition in the actual use process is avoided. Herein, the upper buckling cover and the lower buckling cover can be conveniently mounted and dismounted through the fastening bolts, so that the upper buckling cover and the lower buckling cover can be mounted at the end part of the polyvinyl chloride sheath according to the actual use condition and are connected and fixed by matching with the arranged connecting bolts, the wiring firmness of the flat power cable is ensured, and the falling condition is avoided.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a polyvinyl chloride insulated and sheathed flat power cable. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. 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. [0003] The actual protection and insulation effects of power cables on the market are poor, and the outdoor use effect is poor. Long-term use is prone to leakage and unstable power transmission. Poor, and at the same time the c...
