Novel armored cable

Abstract

The invention relates to a novel armored cable. The novel armored cable comprises five insulated cable cores, wherein a wrapping tape layer is wound outside the insulated cable cores, an inner sheath layer is extruded outside the wrapping tape layer, a steel wire armor layer in the same direction of the insulated cable cores is arranged outside the inner sheath layer, an outer sheath layer is extruded outside the steel wire armor layer and filling layers are arranged in gaps in the wrapping tape layer. The insulation stability of the cross-linked polyethylene insulating layers and the silicon rubber outer sheath layer is good, the tensile strength and compressive strength of the galvanized medium-carbon steel wire armor layer are high, the bending radius is large, the novel armored cable can be effectively prevented from being bitten by animals such as mice, and the service life is long.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a novel armored cable. Background technique [0002] Armored cables are made of conductors of different materials packed in metal sleeves with insulating materials, and are processed into a flexible and solid assembly. They are mainly used for the transmission of power and electric energy in metallurgy, chemical, electric, Cables are generally laid in cable trenches or cable trays, which cannot effectively prevent the gnawing of mice and damage to the cables by external mechanical forces. In order to protect the structure of the cables and ensure normal electrical performance, adding an armor layer to the cables is It seems very important. Contents of the invention [0003] The invention provides an armored cable with good insulation stability and high compressive strength. [0004] In order to achieve the above object, the present invention adopts the following technical methods:...
