Abstract
It the utility model is related to a kind of novel ethylene propylene rubber insulated cable, including proof copper-wire braided screen layer, the oversheath being extruded on the outside of proof copper-wire braided screen layer, the inner sheath on the inside of proof copper-wire braided screen layer, the inside of the inner sheath is provided with three strands of cores being mutually twisted together, and low smoke and zero halogen oxygen barrier material is filled with the space between the inner sheath and core.The core includes conductor, the ethylene propylene rubber insulated layer being extruded on the outside of conductor.The utility model is reasonable in design, and traditional twisted processing mode is substituted by the way of occlusion, reduces the cost of the manufacturing, while simplifies production technology, shortens the manufacturing cycle, and can improve the structural strength of cable in itself.
Description
Technical field
Field of cable technology is the utility model is related to, specifically a kind of novel ethylene propylene rubber insulated cable.
Background technology
With industry sizes such as China electric power industry, data communication industry, urban track traffic industry, car industry and shipbuildings
Constantly expand, the demand of electric wire will also be increased rapidly, following electric wire industry also has huge development potentiality.2008
November, China are reply world financial crisis, and government decided puts into 4 trillion yuans and pulls domestic demand, wherein having about more than 40% to use
In urban and rural power grids construction and upgrading.National wires and cables industry has the good market opportunity again, and various regions electric wire enterprise grabs
Firmly opportunity, meet new round urban and rural power grids construction and upgrading.
Existing cable is all to form cable core by the way of twisted mostly, needs input a large amount of in process of manufacture
Twisted equipment just can be achieved, cost input is higher, and also the cost of cable necessarily uprises, complex process, the production cycle compared with
It is long, it can not meet the supply requirement in market.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of novel ethylene propylene rubber insulated cable.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of novel ethylene propylene rubber insulated cable, including proof copper-wire braided screen layer, be extruded on the outside of proof copper-wire braided screen layer
Oversheath, the inner sheath on the inside of proof copper-wire braided screen layer, the inside of the inner sheath is provided with three strands and is mutually twisted
Core together, low smoke and zero halogen oxygen barrier material is filled with the space between the inner sheath and core.
The core includes conductor, the ethylene propylene rubber insulated layer being extruded on the outside of conductor.
The outside of the ethylene propylene rubber insulated layer is provided with the arc bite to stretch out.
Outer arcuate profile uniform installation by adhering of the inside of the arc bite along arc bite has and led
The parallel steel wire of body axis.
The exterior arc surface of the arc bite is provided with the arc columnar projections being distributed along conductor axis direction
And the arc cylindrical recesses being coincide with arc column raised profile, arc columnar projections on a core and another
The arc cylindrical recesses of adjacent core are mutually engaged.
The beneficial effects of the utility model are：The utility model is reasonable in design, and tradition is substituted by the way of occlusion
Twisted processing mode, reduce the cost of the manufacturing, while simplify production technology, shorten the manufacturing cycle, and can carry
The structural strength of high cable in itself.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is internal structure schematic diagram of the present utility model；
Fig. 2 is structural representation when two adjacent strand cores of the present utility model separate；
Fig. 3 is Fig. 2 I partial enlarged drawings.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
It is expanded on further in face of the utility model.
As shown in Figure 1 to Figure 3, a kind of novel ethylene propylene rubber insulated cable, including proof copper-wire braided screen layer 2, it is extruded in copper
Oversheath 1, the inner sheath 3 installed in the inner side of proof copper-wire braided screen layer 2 in silk woven shield 2 outside, the inner sheath 3 it is interior
Portion is provided with three strands of cores being mutually twisted together, and low smoke and zero halogen is filled with the space between the inner sheath 3 and core
Oxygen barrier material 10, the overall degree of packing can be improved using low smoke and zero halogen oxygen barrier material 10.Core of the present utility model is using occlusion
Mode is fixed together, and firmness is high, compared with traditional occlusion mode, simplifies production technology, reduces the manufacturing
Cost, while also can guarantee that the tautness and intensity of cable.
The core includes conductor 4, is extruded in the ethylene propylene rubber insulated layer 6 in the outside of conductor 4.
The outside of the ethylene propylene rubber insulated layer 6 is provided with the arc bite 7 to stretch out.So of the present utility model three
Have an arc bite 7 on individual core respectively, in cable making process in, only three arc bites 7 need to mutually be stung
It is combined, you can realize the connection of internal structure, conveniently realize assembling.
Outer arcuate profile uniform installation by adhering of the inside of the arc bite 7 along arc bite 7 have with
The steel wire 5 of the diameter parallel of conductor 4, the structural strength of entirety can be improved using steel wire 5, while also can prevent cable from using
Occur flexural deformation in journey, also can play guaranteeing role with adjacent being engaged for arc bite 7 to arc bite 7.
It is convex that the exterior arc surface of the arc bite 7 is provided with an arc column along the distribution of the axis direction of conductor 4
Play 8 and the arc cylindrical recesses 9 being coincide with the profile of arc columnar projections 8, arc columnar projections 8 on a core and
The phase of arc cylindrical recesses 9 occlusion of another adjacent core, structure design connection, sound construction after occlusion.
Designed using occlusion of the present utility model, not only simplify technique during the cable manufacturing, but also can
When reclaiming in the cable later stage, facilitate the recovery of disassembling of cable, reduce cost recovery and improve organic efficiency.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has
Various changes and modifications, these changes and improvements are both fallen within claimed the scope of the utility model.The requires of the utility model
Protection domain is by appended claims and its equivalent thereof.
