Abstract

The invention provides a photovoltaic thermal-conductive flame-retardant cable which comprises a rubber shell. A winding layer is connected to the inner wall of the rubber shell in an adhesive mode, buckle structures are arranged on the inner side of the winding layer at equal intervals, a plurality of telescopic clamping structures are arranged on the inner sides of the buckle structures, and gaps between a plurality of cables and the winding layer are filled with special-shaped filler. Corresponding locking is achieved through cooperation of the buckle structure and the telescopic clamping structure, finally corresponding clamping is achieved, and therefore the cable can be blocked at intervals, and then the isolation performance is better by adding the filler.

Description

technical field

[0001] The invention relates to the technical field of cables, and mainly relates to a photovoltaic heat conduction flame retardant 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, outgoing lines of power stations, internal power supply of 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] Existing power cables are combined by multiple groups of cables, then blocked by fillers, and finally formed into a total cable by enamelling.

[0004] However, since the cable is often bent during use, the cable and its cas...
