Abstract

The invention discloses a flame-retardant power cable, and belongs to the technical field of cables. The technical key points are that the flame-retardant power cable comprises a cable main body, a filling layer is arranged in the middle of the cable main body, and a carbon fiber layer, an aerogel felt layer, an ethylene-propylene copolymer and a halogen-free flame-retardant jacket are sequentially arranged on the outer side wall of the filling layer from inside to outside. A polyvinyl chloride column body is arranged in the middle of the filling layer, a plurality of uniformly distributed alumina fiber blocking edges are fixedly connected to the outer side wall of the polyvinyl chloride column body, and conductor main bodies are arranged between every two adjacent alumina fiber blocking edges. An alumina fiber coating and rock wool are sequentially arranged on the inner side wall of the halogen-free flame-retardant outer sleeve from outside to inside. The polyvinyl chloride cylinders reinforce the non-deformability of a power cable, facilitate the protection to the conductors and prevent the conductors from being broken, and the polyvinyl chloride cylinders are made of ultra-light high-temperature heat-insulating materials, so that the flame-retardant performance of the power cable is further enhanced, the flame-retardant effect is achieved inside and outside the power cable, and the safety performance of the power cable is improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a flame-retardant power cable. Background technique [0002] Power cables are cable products used to transmit and distribute high-power electric energy in the backbone lines of power systems. The basic structure of power cables consists of four parts: core (conductor), insulating layer, shielding layer and protective layer. It is 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. [0003] Existing power cables have poor flame retardancy and low pressure resistance, so that the cables have potential safety hazards. Contents of the invention [0004] The invention provides a flame-retardant power cable, which aims to solve the problem that the existing power cable has poor flame-retardant performance and low pressure resistance, which c...
