Description
Technical field
The utility model relates to mining cable technical field, particularly relates to a kind of fire resistant tensile type rubber sleeve flexible cable.
Background technology
Mining cable refers to the coal mining industry ground installation of will and underground equipment electric wire cable product. comprising coal-winning machine, transporter, communicate, illumination and signalling arrangement cable, and electric drill cable, the feed cable etc. of cap lamp electric wire and underground moving transformer station.
MY-0.38/0.66kV, MYP-0.38/0.66kV and MYP-0.66/1.14kV coal mine moving rubber sleeve flexible cable is the mining flame-retardant cable that People's Republic of China's coal industry (unification) designs, and product is used for the power supply connection that underground coal mine rated voltage is the various underground moving coal excavation apparatus of 0.38/0.66kV or 0.66/1.14kV.
In actual use, tensile strength can not meet the demand of actual working environment to original mining cable completely, does not have enough dielectric strengths between power wire core and ground connection core, and be easily short-circuited the defects such as fault.Meanwhile, underground work circumstance complication, the spot fire that especially fire or subside causes is the biggest threat to cable.
Utility model content
The purpose of this utility model solves the deficiencies in the prior art, provides between a kind of heart yearn and have enough dielectric strengths, the cable of the fault that is not easily short-circuited, high temperature resistant, tension.
The technical solution adopted in the utility model is: a kind of fire resistant tensile type rubber sleeve flexible cable, comprise some conductors, described conductor is socketed with insulating barrier and screen successively, described some conductors are plum blossom-shaped arrangement, the conductor of the described arrangement in plum blossom-shaped is socketed packed layer outward, is filled with cordage between the conductor of described socket insulating barrier and screen; Described packed layer is socketed with restrictive coating and resilient sleeve outward successively, is provided with elastic threads in described resilient sleeve.
As further improvement of the utility model, described screen adopts semiconductive material to extrude or wrapped formation, and the volume resistance of screen controls 10
2~ 10
4within the scope of Ω/cm.
Further improve as of the present utility model, described some conductors adopt tinned copper wire flexible conductor.
The utility model adopt beneficial effect be: the cable of this structure its conduct electricity very well, have enough dielectric strengths between core conductor, be not easily short-circuited fault.Meanwhile, the structural design of cordage and elastic threads, rises to new height by the tensile property of cable, and this outer cable also has resistance to compression, wear-resisting and fire resistance; Screen adopts and extrudes or lapping structure, and make electric field balanced, the better effects if of shielding, the volume resistance of semi-conductive layer controls 10

4within the scope of Ω/cm, outer conducting layer is easily peeled off, and is convenient to make cable joint.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Shown in figure: 1 conductor, 2 insulating barriers, 3 screens, 4 packed layers, 5 cordage, 6 restrictive coatings, 7 elastic threads, 8 resilient sleeve.
Embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, a kind of fire resistant tensile type rubber sleeve flexible cable, comprise some conductors 1, described conductor 1 is socketed with insulating barrier 2 and screen 3 successively, the arrangement in plum blossom-shaped of described some conductors 1, the conductor 1 outer socket packed layer 4 of the described arrangement in plum blossom-shaped, is filled with cordage 5 between the conductor of described socket insulating barrier and screen; Described packed layer 4 is outer is socketed with restrictive coating 6 and resilient sleeve 8 successively, is provided with elastic threads 7 in described resilient sleeve 8.
Described screen 3 adopts semiconductive material to extrude or wrapped formation, and the volume resistance of screen 3 controls 10
2~ 10
4within the scope of Ω/cm.
Described some conductors 1 adopt tinned copper wire flexible conductor.
The cable of this structure its conduct electricity very well, have enough dielectric strengths between core conductor, be not easily short-circuited fault.Meanwhile, the structural design of cordage and elastic threads, rises to new height by the tensile property of cable, and this outer cable also has resistance to compression, wear-resisting and fire resistance; Screen adopts and extrudes or lapping structure, and make electric field balanced, the better effects if of shielding, the volume resistance of semi-conductive layer controls 10
2~ 10
4within the scope of Ω/cm, outer conducting layer is easily peeled off, and is convenient to make cable joint.
Technical parameter and points for attention for cable:
1, the packaging of cable, transport, storage and points for attention:
(1) cable should neatly around on cable delivery drum.Cable piece allows baling.
(2) cable should be avoided depositing in the open, and cable hank does not allow to keep flat.
(3) forbid to abandon from eminence the cable hank that cable is housed in transport, forbid mechanical damage cable.
(4), when lifting package, forbid a few dish to lift simultaneously.On the means of transportation such as vehicle, boats and ships, cable hank must be put surely, and fixes by appropriate method, prevents knock against each other or overturning.
(5) transport and storage: cable can adapt to the transport of water, land and air all traffic.Should note in transport and storage process:
A) prevent moisture moisture from invading cable;
B) severe bends and other mechanical damages is prevented;
C) prevent high temperature and tan by the sun in the sun.
2, Attention question is answered in cable installation process
(1) in cabling process as people should repair immediately for causing quality accident etc. (as outer jacket damage).
(2) cable is changing dish and should note in laying not making cable that too small bending discounting occurs.
Those skilled in the art should know; protection scheme of the present utility model is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to the utility model spirit, the various conversion that the utility model carries out all are dropped in protection range of the present utility model.
