Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 and figure 2 As shown, the light polyvinyl chloride sheathed cable of the present invention includes a sheath 1 and a core 2; the outer surface of the core 2 is provided with an annular limiting groove 23;

[0020] The wire core 2 is provided with a central hole 21; the wire core 2 is provided with wire holes uniformly distributed along the circumference; the wire hole is provided with a wire 3; the wire core 2 is provided with a heat dissipation channel 22;

[0021] The sheath 1 sequentially includes a cover layer 11, an electrostatic shielding layer 12, a buffer flame retardant layer 13, a stretch-resistant protective layer 14, and a polyvinyl chloride surface layer 15 from the inside to the outside; the cover layer 11 is made of insulating polyvinyl chloride film.

[0022] During use, since the sheath 1 sequentially includ...

Abstract

The invention discloses a light polyvinyl chloride sheathed cable. According to the light polyvinyl chloride sheathed cable,sheath installation can be facilitated, and sheath replacement can be facilitated. The light polyvinyl chloride sheathed cable comprises a sheath and a wire core; an annular limiting groove is formed in the outer surface of the wire core; an annular limiting groove is formed in the wire core; wire holes which are uniformly distributed along the circumference are formed in the wire core; a heat dissipation channel is arranged in the wire core; wires are arranged in the wire holes; the sheath comprises a sleeving layer, an electrostatic shielding layer, a buffer flame-retardant layer, a tensile protection layer and a polyvinyl chloride surface layer sequentially distributed from inside to outside, wherein the sleeving layer is made of an insulating polyvinyl chloride film. According to the light polyvinyl chloride sheathed cable, the installation of the sheath can be facilitated, and the replacement of the sheath is facilitated; and meanwhile, the service life of the cable can be prolonged.

Description

technical field [0001] The invention relates to a sheathed cable, in particular to a light polyvinyl chloride sheathed cable. Background technique [0002] As we all know: cables are conductors covered with insulating layers, protective layers, shielding layers, etc. used to transmit power or signal currents, and signal voltages. According to the voltage, it can be divided into high-voltage cables and low-voltage cables. Compared with low-voltage overhead lines and low-voltage overhead insulated lines, although low-voltage cable lines are more expensive and difficult to lay and maintain, they are reliable in operation, do not erect poles, do not occupy the ground, are not unsightly, and are less affected by the outside world. characteristics, and are widely used in low-voltage power distribution systems. [0003] Existing sheathed cables such as a kind of sheathed replaceable control cable disclosed in Chinese patent application 201711216946.1, [0004] Including: cable c...
