Flame-retardant power cable

Abstract

The invention provides a flame-retardant power cable, including a glass fiber high-temperature rope, a first wire core group, a second wire core group, a flame-retardant belt, a first filling layer, a flame-retardant inner lining layer, a shielding layer, an armor layer, a flame-retardant outer lining layer and an outer sheath. The first wire core group includes two first wire cores which are symmetrically arranged with the glass fiber high-temperature rope being the center; the second wire core group includes two second wire cores which are symmetrically arranged with the glass fiber high-temperature rope being the center; the flame-retardant inner lining layer is wrapped outside the first wire core group and the second wire core group, the first filling layer is filled among the flame-retardant inner lining layer, the first wire core group and the second wire core group, the flame-retardant belt is arranged inside the first filling layer and is wrapped outside the first wire core group and the second wire core group, the shielding layer is wrapped outside the flame-retardant inner lining layer, the armor layer is wrapped outside the shielding layer, the flame-retardant outer lining layer is wrapped outside the armor layer, and the outer sheath is wrapped outside the flame-retardant outer lining layer. The flame-retardant power cable provided by the invention has excellent mechanical property and flame-retardant property.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a flame-retardant power cable. Background technique [0002] Cables play a huge role in the construction of the national economy as carriers of cables and information dissemination. With the acceleration of urbanization and the rapid development of power transmission and communications, people have higher and higher requirements for AC power cables. The use environment of AC power cables is complex, and it is easy to burn when encountering high temperatures. For some extreme high temperature environments, an AC power cable with excellent flame retardant performance is needed to improve the safety of the operating occasion. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a flame-retardant power cable. [0004] A flame-retardant power cable proposed by the present invention includes a glass fibe...
