Abstract
The utility model discloses a cold-resistant anti-snow cable. The cable comprises a conductor and a sheath. The conductor includes a plurality of groups of conductive cores. The conductive cores are coated by an insulating layer. A reinforcing layer is made of metal fiber material and arranged on the inner wall of the sheath. The sheath has a cross section of olive shape in the radical direction. The sheath is made of cold-resistant material. The cold-resistant anti-snow cable provided by the utility model can prevent frost cracks of the sheath and prevent snow accumulation.
Description
Technical field
The utility model relates to a kind of cable, and more particularly, it relates to a kind of cold-resistant anti-accumulated snow cable.
Background technology
Cable need to carry out cold-proof processing to cable when being applied to cold environment, prevents that cable from occurring that fracture damages personnel's life and communal facility in use.Cable comprises conductor and shell, and the common cable that is applied to low temperature environment mainly carries out cold-resistant processing to the shell of cable and prevents that shell from occurring that in low temperature environment cracking makes inner conductor be exposed to housing exterior.But this cable usually can be piled up and have a large amount of accumulated snow under snowy weather above cable, the pressure that cable is subject to radially easily causes fracture.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of and prevents shell bursting by freezing and prevent the cold-resistant anti-accumulated snow cable that accumulated snow is piled up.
For achieving the above object, the utility model provides following technical scheme: a kind of cold-resistant anti-accumulated snow cable, comprise conductor and shell, described conductor comprises many group conductive core, described conductive core outside is all enclosed with insulating barrier, and described outer casing inner wall is provided with reinforced layer, and described reinforced layer is that metallic fiber material is made, described shell is set to olive shape along conductor radial section, and described shell is that cold-resistant material is made.
By adopting technique scheme; shell cross section is set to olive shape; in snow sky, accumulated snow is by the easier inclined-plane landing along olive shape shell; effectively reduce the accumulation of accumulated snow on cable; protected the safety of cable; secondly outer casing inner wall is provided with reinforced layer and has promoted cable resistance to tension, prevents that accumulated snow from making cable breakage, and shell adopts cold-resistant material to guarantee that shell can be because cracking appears in low temperature.
The utility model is further set to: described conductive core is four groups, and conductive core is evenly distributed in enclosure.
By adopting technique scheme, cable is conveniently connected with three-phase electricity circuit system, promote the applicability of cable.
The utility model is further set to: described insulating barrier is that bittern-free flame-proof material is made.
By adopting technique scheme, effectively reduce the generation of cable fire, the amount of smoke that simultaneously makes cable fire produce reduces, and is conducive to environmental protection.
Accompanying drawing explanation
Fig. 1 is the structure diagram of the cold-resistant anti-accumulated snow cable embodiment of the utility model.
Description of reference numerals: 1, shell; 2, conductive core; 3, insulating barrier; 4, reinforced layer.
Embodiment
With reference to Fig. 1, the cold-resistant anti-accumulated snow cable embodiment of the utility model is described further.
A kind of cold-resistant anti-accumulated snow cable, comprise conductor and shell 1, described conductor comprises many group conductive core 2, described conductive core 2 outsides are all enclosed with insulating barrier 3, described shell 1 inwall is provided with reinforced layer 4, described reinforced layer 4 is made for metallic fiber material, and described shell 1 is set to olive shape along conductor radial section, and described shell 1 is made for cold-resistant material.Shell 1 cross section is set to olive shape; during installation, make shell 1 tip, two ends vertically arrange; in snow sky, accumulated snow is by the easier inclined-plane landing along olive shape shell 1; effectively reduce the accumulation of accumulated snow on cable; protected the safety of cable; secondly shell 1 inwall is provided with reinforced layer 4 and has promoted cable resistance to tension, prevents that accumulated snow from making cable breakage, and shell 1 adopts cold-resistant material to guarantee that shell 1 can be because cracking appears in low temperature.
Described conductive core 2 is four groups, and conductive core 2 is evenly distributed in shell 1 inside.Cable is conveniently connected with three-phase electricity circuit system, promotes the applicability of cable.
Described insulating barrier 3 is made for bittern-free flame-proof material.Effectively reduce the generation of cable fire, the amount of smoke that simultaneously makes cable fire produce reduces, and is conducive to environmental protection.
