Description
Technical field
The utility model belongs to power line technical field, especially relates to a kind of power line with sheath.
Background technology
In existing technology, power line is the electric wire of transmission electric current, and the mode of usual electric current transmission is point-to-point transmission.
Common rubber sleeve flexible cable resistance to low temperature difference, especially at northern area, cable cover(ing) there will be crack performance at low temperatures, seriously
Affect the use of cable, and bring very big hidden danger to production safety and personal safety；The bulk strength of power line is relatively low simultaneously,
During use, can pull power line unavoidably, make the conductor break in power line, tensile property difference, reducing it makes
Use the life-span.
Utility model content
The purpose of this utility model be to provide a kind of simple in construction, improve its cold resistance and play fire prevention, insulation effect,
Improve the power line of the tensile property of power line, be particluarly suitable for the outdoor use of northern area.
The technical solution of the utility model is: a kind of power line with sheath, including sheath and many in being located at sheath
Individual conductor, is sequentially provided with cold-resistant layer, external insulation layer, screen layer inside sheath from outside to inside, and described screen layer is by tin-coated copper
Silk braiding forms, and described external insulation layer uses Ceramic silicon rubber to extrude formation, fills between described screen layer and conductor
Having single, the region between adjacent two conductors is provided with tears rubber-insulated wire, and described conductor includes that layers of copper is coated on outside steel core, at copper
Layer outer felt is wound with the banding reinforcement of insulation, is coated with inner insulating layer outside the banding reinforcement of insulation.
Further, it is provided with 3 conductors in described sheath.
Further, described cold-resistant layer is ethylene-propylene-diene monomer glue-line, has preferable cold resistance, at the height of subzero 40 DEG C
Cold air remains to keep good elasticity, wearability and bending property under waiting.
Further, described jacket outer surface is provided with anti-slip veins.
The utility model has the advantage that and with good effect is: owing to using technique scheme, the cold-resistant layer of setting, absolutely
Edge layer, improves its cold resistance and plays fire prevention, the effect of insulation；Conductor uses layers of copper to be coated on steel core, has saved the consumption of copper,
Improve the tensile property of power line.

Detailed description of the invention
As Figure 1-3, the technical solution of the utility model is: a kind of power line with sheath, including sheath 1 and
The multiple conductors being located in sheath 1, are sequentially provided with cold-resistant layer the 2nd, external insulation layer the 3rd, screen layer 4, institute inside sheath 1 from outside to inside
The screen layer 4 stated is formed by tinned copper wire braiding, and described external insulation layer 3 uses Ceramic silicon rubber to extrude formation, Neng Gouyou
Effect prevents artificial destruction from destroying, and under Fires Occurred, its insulating barrier 3 can burn till hard ceramic-like, is coated with closely
At conductive surface, serve fire prevention and the effect of insulation, farthest reduce loss, described screen layer 4 and conductor it
Between be filled with single 5, the region between adjacent two conductors is provided with tears rubber-insulated wire 6, tears rubber-insulated wire 6 owing to being provided with, and only need to pull and tear
Line skin can quickly be cut open by rubber-insulated wire 6, easy to operate, completely the instrument without specialty, it is to avoid hinders hand and scratches core etc. now
As occurring, more effectively protecting the serviceability of personal safety and electric wire, bringing convenience to use, construction, described leads
Body includes that layers of copper 7 is coated on outside steel core 8, is wound with the banding reinforcement 9 of insulation in layers of copper 7 outer felt, and the banding in insulation is strengthened
Being coated with inner insulating layer 10 outside part 9, conductor uses layers of copper 7 to be coated on steel core 8, adds the bulk strength of power line, and
Save the consumption of copper, reduce cost, energy-saving safe.
It in the present embodiment, in described sheath 1, is provided with 3 conductors.
In the present embodiment, described cold-resistant layer 2 is ethylene-propylene-diene monomer glue-line, has preferable cold resistance, at subzero 40 DEG C
Puna under remain to keep good elasticity, wearability and bending property.
In the present embodiment, described sheath 1 outer surface is provided with anti-slip veins 11.
Above an embodiment of the present utility model is described in detail, but described content is only of the present utility model
Preferred embodiment, it is impossible to be considered for limiting practical range of the present utility model.All made according to the utility model application range
Impartial change and improvement etc., all should still belong within patent covering scope of the present utility model.
