Abstract
The utility model relates to an ethylene propylene rubber insulation monitoring type mine cold-resistant flexible cable, which comprises a plurality of cable conductors and insulation layers and insulation shielding layers. The insulation layers and the insulation shielding layers are arranged on outer layers of the cable conductors, and a cable forming belting is sleeved on the outsides of the insulation shielding layers. The flexible cable is characterized in that tin plated copper wire braiding shielding layers are sleeve on outsides of the insulation shielding layers, a filling layer is arranged between the tin plated copper wire braiding shielding layers and the corresponding cable forming belting, a semiconductor belt wrapping layer is sleeved on the outside of the cable forming belting, and a protective jacket is sleeved outside the semiconductor belt wrapping layer. The ethylene propylene rubber insulation monitoring type mine cold-resistant flexible cable has the advantages of capability of effectively guaranteeing cleanness of the insulation layers and electric field evenness, long service life, fine effect in low-temperature resistance, excellent tearing resistance and the like.
Description
Technical field
The utility model relates to a kind of, especially relates to the mining cold-resistant flexible cable of a kind of ethylene propylene rubber insulated monitoring type.
Background technology
As everyone knows, cold-resistant flexible cable is applicable to that rated voltage 25kV and following opencut and underground driving jumbo are with ethylene-propylene rubber insulation haloflex rubber sheath high pressure rubber sleeve flexible cable.
Scarcely low temperature resistant and tear resistance of the cable of Sheng Chaning and UV resistant performance are poor in the market, influence the useful life of cable.And state energy producer only produces 10kV's mostly, and so the cable of voltage levels can only adopt three-layer co-extruded equipment.
At present domestic producer with three-layer co-extruded equipment seldom.Wrapped form is adopted in inner shield of most of producers or external shield, and this kind structure is difficult to guarantee the cleaning of insulating barrier and the uniformity of electric field, influences the useful life of cable.
Summary of the invention
The utility model mainly is at the above-mentioned technical problem of existing in prior technology, and a kind of uniformity, long service life, mining cold-resistant flexible cable of low temperature resistant ethylene propylene rubber insulated monitoring type effective, that tear resistance is good that can effectively guarantee insulating barrier cleaning and electric field is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the mining cold-resistant flexible cable of a kind of ethylene propylene rubber insulated monitoring type, comprise many cable conductors and be arranged on outer field insulating barrier of cable conductor and insulation screen, insulation screen is arranged with the stranding band outward, it is characterized in that the described insulation screen outside is arranged with the tinned copper wire woven shield, be packed layer between described tinned copper wire woven shield and the stranding band, the described stranding band outside is arranged with the semi-conductive tape covering, and described semi-conductive tape covering is arranged with protective coat outward.The utility model is example with the three-core cable, cable conductor adopts the circular annealing of multiply tinned wird to be twisted into circle, extrude conductor screen+ethylene propylene rubber insulated layer+external shield, insulation screen weaves the tinned copper wire woven shield outward, adopt DOS as low temperature resistant plasticizer, carbon black as the prescription design that ultra-violet absorber, white carbon strengthen, make the rubber outer protection cover have the performance of low temperature resistant, high anti-tear, fire-retardant, antiultraviolet.
As preferably, be provided with sheath between described stranding band and the semi-conductive tape covering.Existing low temperature resistant preferably, high anti-tear, fire-retardant, the preventing ultraviolet effect of the cable of this kind structure has the peelable performance of external shield again, and it is superior also to be easy to construction and combination property.
As preferably, described protective coat adopts low temperature resistant nitrile rubber manufacturing.Nitrile rubber is adopted in external shield, reaches strippable requirement.
As preferably, described cable conductor outer surface is laid with conductor shield.Conductor shield, insulating barrier, insulation screen are once extruded, and guarantee that three-layered node closes closely, the smooth electric field in interface is even.
Therefore, the utlity model has the uniformity that can effectively guarantee insulating barrier cleaning and electric field, long service life, low temperature resistant effective, characteristics such as tear resistance is good.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in Figure of description 1, the mining cold-resistant flexible cable of a kind of ethylene propylene rubber insulated monitoring type, comprise many cable conductors 1 and be arranged on outer field insulating barrier 3 of cable conductor and insulation screen 4, insulation screen is arranged with stranding band 7 outward, the insulation screen outside is arranged with tinned copper wire woven shield 5, be packed layer 6 between tinned copper wire woven shield and the stranding band, the stranding band outside is arranged with semi-conductive tape covering 9, and the semi-conductive tape covering is arranged with protective coat 10 outward.Be provided with sheath 8 between stranding band 7 and the semi-conductive tape covering 9.Protective coat adopts low temperature resistant nitrile rubber manufacturing.The cable conductor outer surface is laid with conductor shield 2.
The utility model is example with the three-core cable, cable conductor adopts the circular annealing of multiply tinned wird to be twisted into circle, extrude conductor screen+ethylene propylene rubber insulated layer+external shield, insulation screen weaves the tinned copper wire woven shield outward, adopt DOS as low temperature resistant plasticizer, carbon black as the prescription design that ultra-violet absorber, white carbon strengthen, make the rubber outer protection cover have the performance of low temperature resistant, high anti-tear, fire-retardant, antiultraviolet.Existing low temperature resistant preferably, high anti-tear, fire-retardant, the preventing ultraviolet effect of the cable of this kind structure has the peelable performance of external shield again, and it is superior also to be easy to construction and combination property.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
