Background technology
In order to transmission of electricity when do not produced to external leakage from conductor electric field, magnetic field, be equipped with shielded layer in power transmission cable.
Such as in the motor of linear running or the reciprocal runtime of elevator etc, the power transmission cable being connected with dynamical element needs instead
Multiple bending, it is conductive since the buckle resistance of the electric conductor in power transmission cable can be much smaller than the buckle resistance energy of insulating coating
Body produces metal fatigue after alternating bending, it most fractures at last, and service life is limited.And replaced in reciprocal runtime complete
Portion's power transmission cable, then cause equipment to be stopped work.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of modified power transmission cable.This
Utility model conductor extends in a spiral form, any bending of power transmission cable, can only make conductor that slight bending, the transmission of electricity occur
Cable bears the excellent in te pins of durability of distortion, is also able to maintain that the performance of shielding.
To achieve the above object, the utility model uses following technical proposals：
A kind of modified power transmission cable, including conductor and insulation system, are equipped with successively between the conductor and insulation system
Waterproof layer and silica gel resistance to compression layer, insulation system periphery are equipped with shielded layer, and shielded layer periphery is equipped with sheath；The insulation system includes
First semi-conductive layer, the second semi-conductive layer and insulating layer between the two, wherein, the first semi-conductive layer is arranged on silica gel resistance to compression
The periphery of layer；Each layer cylindrical structure of the conductor and its periphery in addition to sheath is in the form of circular helix in sheath
Extend along the extending direction of sheath, primary antibody drawstring is equipped with sheath, the tension rope is by whole radial sections in sheath
The center of circle；Along the circumferential direction it is evenly spaced apart to be provided with three grooves in the sheath, the groove extends parallel with sheath, recessed
Groove is both provided with sealing strip in the opening of sheath lateral wall.
Preferably, microcellular structure is included in the sealing strip.
Preferably, the cylindrical structure diameter of the circular helix is respectively less than the diameter of sheath.
Preferably, the conductor is at least one.
Preferably, the radial section of the conductor is rounded.
Preferably, the tension rope is steel wire or cordage.
Preferably, is equipped with expelling mouse agent in the groove, can solve power transmission cable in the prior art easily stung by mouse it is bad
And cause the technical problem of power supply trouble.
The beneficial effects of the utility model are：
In power transmission cable, the conductor in sheath extends the utility model in a spiral form, power transmission cable it is any curved
Folding, can only make conductor that slight bending occur, substantially prolongs the service life of conductor.The centrally disposed tension rope of sheath can be held
The pulling force that power transmission cable is subject in the longitudinal direction is carried, prevents that the pitch of conductor from surprisingly being elongated.
Brief description of the drawings
Fig. 1 is the utility model power transmission cable with length direction sectional view；
Fig. 2 is the structure diagram of the utility model；
Wherein 1. conductors, 2. waterproof layers, 3. silica gel resistance to compression layers, 4. first semi-conductive layers, 5. insulating layers, 6. second semiconductives
Layer, 7. shielded layers, 8. sheaths, 9. sealing strips, 10. grooves, 11. tension ropes.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figs. 1-2, a kind of modified power transmission cable, including conductor 1 and insulation system, the conductor 1 and insulation are
Waterproof layer 2 and silica gel resistance to compression layer 3 are equipped between system successively, insulation system periphery is equipped with shielded layer 7, and 7 periphery of shielded layer is equipped with shield
Set 8；The insulation system includes the first semi-conductive layer 4, the second semi-conductive layer 6 and insulating layer 5 between the two, wherein, the
One semi-conductive layer 4 is arranged on the periphery of silica gel resistance to compression layer 3；Each layer cylinder knot of the conductor 1 and its periphery in addition to sheath 8
Extending direction of the structure along sheath 8 in sheath 8 in the form of circular helix extends, and primary antibody drawstring 11, institute are equipped with sheath 8
State the center of circle of the tension rope 11 by whole radial sections in sheath 8；Along the circumferential direction it is evenly spaced apart to be provided with the sheath 8
Three grooves 10, the groove 10 extend parallel with sheath 8, and groove 10 is both provided with close in the opening of 8 lateral wall of sheath
Strip of paper used for sealing 9.
Based on the above technical solutions, microcellular structure is included in the sealing strip 9.
Based on the above technical solutions, the cylindrical structure diameter of the circular helix is respectively less than the diameter of sheath 8.
Based on the above technical solutions, the conductor 1 is at least one.
Based on the above technical solutions, the radial section of the conductor 1 is rounded.
Based on the above technical solutions, the tension rope 11 is steel wire or cordage.
Based on the above technical solutions, expelling mouse agent is equipped with the groove 10, can solves to transmit electricity in the prior art
