Abstract

The invention discloses a water-blocking and tension-resistant medium-voltage cable, which is composed of a power core, an armor layer, an inner sheath layer, an aramid fiber braided shielding layer, an insulating layer, a polyvinyl chloride insulating layer and an outer sheath layer composition. The power core is composed of conductor, EPDM insulation layer, non-magnetic metal armor layer and galvanized copper wire shielding layer, and the inner sheath layer and outer sheath layer are low-smoke halogen-free polyethylene jacket layer. This kind of cable has the advantages of temperature resistance, oil resistance, ultraviolet light resistance, waterproof and chlorine, which greatly improves the mechanical properties of the cable. At the same time, no toxic gas will be released when the cable encounters a fire, and the cable can be rotated freely with the windmill.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a water-blocking and tension-resistant medium-voltage cable. Background technique [0002] The conductors of this cable do not break, the insulation and sheath materials do not crack, and there is no short circuit due to rain. However, there is no water-blocking and tensile-resistant low-voltage cable with excellent tensile and water-blocking properties so far. Contents of the invention [0003] The purpose of this patent is to avoid the disadvantages of the above-mentioned prior art, and to provide a water-resistant and tension-resistant medium-voltage cable with excellent tensile and water-resistant properties. [0004] The present invention is realized by adopting the following technical solutions: a water-blocking and tension-resistant medium-voltage cable, which is composed of a power core, an armor layer, an inner sheath layer, an aramid fiber braided shielding layer, an insulating...
