Abstract
A rubber sheathed flexible cable used in a coal mine and a frequency converter belongs to the mining cable technology field, and comprises a cable core and a sheath wrapped on the outside of the cable core. The rubber sheathed flexible cable used in the coal mine and the frequency converter is characterized in that the cable core comprises a filling material, three power wire cores and three control wire cores, each power wire core comprises a power wire core conductor, a power wire core insulating layer is arranged on the outside of the power wire core conductor, and a semiconductor electrical shielding layer is arranged on the outside of the power wire core insulating layer; each control wire core comprises a control wire core conductor, a control wire core insulating layer is arranged on the outside of the control wire core conductor, and a semiconductor electrical shielding layer is arranged on the outside of the control wire core insulating layer. The beneficial effects of the utility model are that the rubber sheathed flexible cable used in the coal mine and frequency converter is reasonable and simple in structure, easy in production manufacturing and low in cost, and also has the characteristics of good insulating performance, high breakdown voltage, and strong anti-interference capability.
Description
Technical field
The utility model relates to the mine soft cable technical field, relates in particular to a kind of colliery and uses rubber sleeve flexible cable with converter plant.
Background technology
Variable-frequency control technique has obtained using widely in industrial aspect such as oil, metallurgy, generating, railway, mines at present, especially in the colliery, is widely used.The energy-saving effect of converter plant is fairly obvious, after the use frequency control, has realized the soft start of motor, makes machine operation steady, and the motor bearings wearing and tearing reduce, and have prolonged motor useful life and maintenance period.But the corresponding with it service cable that is used to connect variable-frequency motor and variable frequency power supply is just at the early-stage at present, the common power cable of general employing in the actual installation.Can in a large amount of uses, expose cable breakdown gradually, disturb a series of problems such as big.Therefore it is imperative with rubber sleeve flexible cable with converter plant, imperative to develop a kind of new colliery.
Summary of the invention
The purpose of the utility model is to provide a kind of good insulation preformance, puncture voltage is high, antijamming capability is strong colliery to use rubber sleeve flexible cable with converter plant.
For the purpose that realizes the utility model and solve its technical problem and realize through following technical scheme.
Rubber sleeve flexible cable is used with converter plant in a kind of colliery, comprises the outer sheath that coats of cable core and cable core, it is characterized in that: said cable core comprises inserts, three strands of power cores and three strands of control cores; Said power core comprises a power line core conductor, outside said power line core conductor, is provided with a power line core insulation layer, outside said power line core insulation layer, is provided with semiconductor electric screen layer; Said control core comprises a control line core conductor, outside said control line core conductor, is provided with a control line core insulation layer, outside said control line core insulation layer, is provided with semiconductor electric screen layer.
Said power core and said control core are spaced.
Between said cable core and said sheath, also be provided with a copper wire woven shield.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, but also has characteristics such as good insulation preformance, puncture voltage is high, antijamming capability is strong.
