Abstract

The invention discloses a novel water-blocking and anti-tensile low-voltage cable. The novel water-blocking and anti-tensile low-voltage cable comprises power wire cores, a water-blocking filling layer, an inner sheath layer, an aramid silk fiber woven shielding layer, an insulating layer, a polyvinyl chloride insulating layer and an outer sheath layer, wherein each power wire core comprises a conductor, a butyronitrile insulating layer, a non-magnetic metal armor layer and a zinc-plated copper wire shielding layer; the inner sheath layer and the outer sheath layer are chloroprene rubber sheath layers. The mechanical performance of the cable is greatly improved, no toxic gas is emitted when the cable catches a fire, and the cable can be freely twisted along with a windmill.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a novel water-blocking and tension-resistant low-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] This patent is to avoid the shortcomings of the above-mentioned prior art and provide a new type of water-blocking and tensile-resistant low-voltage cable with excellent tensile and water-blocking properties. [0004] The present invention is achieved by adopting the following technical solutions: a new type of water-blocking and tensile-resistant low-voltage cable, which is composed of a power core, a water-blocking filling layer, an inner sheath layer, an aramid fiber braided shielding layer...
