Abstract
The utility model relates to the field of cable manufacture technology and in particular relates to a frequency-converter-used cable. The frequency-converter-used cable comprises a cable core; a metal-belt-wrapped shielding barrier, a metal-thread-woven shielding barrier, a high-resistance-belt wrapped barrier, and an outer sheath barrier which are successively wrapped round the cable core; and a packing barrier disposed between the cable core and the metal-belt-wrapped shielding barrier. The cable core comprises three main insulated wire cores and three null line insulated wire cores, the main insulated wire core including a first conductor successively wrapped in a first insulating barrier and a second insulating barrier, the null line wire core including a second conductor successively wrapped in a third insulating barrier and a fourth insulating barrier. The frequency-converter-used cable has the advantages of high operating temperature, high strength of corrosion resistance, high strength of voltage impact, and good shielding properties, and is applied in the fields of metallurgy, electricity, petrochemical industry, and mining while matched with frequency converting equipment requiring for high operating temperature and corrosion resistance.
Description
Technical field
The utility model relates to the cables manufacturing technical field, the cable that particularly a kind of frequency converter equipment uses.
Background technology
Various motors are after using frequency control; Realized the soft start of motor, made machine operation steady, the motor bearings wearing and tearing reduce; Motor useful life and maintenance period have been prolonged; Variable-frequency control technique can economize on electricity 30% after high-power frequency conversion bunchers such as oil, metallurgy, generating, railway, mine use, equally also used widely at household electrical appliance in recent years.Because the stack of frequency-changing cable pulse voltage amplitude can reach the operating voltage several times, if the cable insulation coefficient of safety is not high, usually breakdown.Simultaneously the external launching electromagnetic wave of cable body causes the electromagnetic wave environmental pollution easily, thus this just between variable frequency power supply and the motor connecting line---frequency-changing cable has proposed special requirement.
Summary of the invention
The utility model purpose is to provide a kind of cable of frequency converter equipment use; To adapt to frequency converter device security stable operation in the adverse circumstances of high low temperature, acid, alkali, oil, water and etchant gas; Frequency converter equipment is widely used, thereby reduces energy resource consumption.
The utility model comprises cable core, outside said cable core, sets gradually metal tape lapped shielding layer, metal wire knitted screen, high stopband lapping layer and outer jacket; Between said cable core and metal tape lapped shielding layer, packed layer is set; Said cable core comprises three main insulation cores and three zero line insulated wire cores, and said three main insulation cores comprise first conductor, outside said first conductor, set gradually first insulating barrier and second insulating barrier; Said three zero line insulated wire cores comprise second conductor, outside said second conductor, set gradually the 3rd insulating barrier and the 4th insulating barrier.
The utlity model has the working temperature height, high strength corrosion resistant, proof voltage impact are strong, advantages such as advantages of good shielding performance, and the fields such as metallurgy, electric power, petrochemical industry, mine that are applicable to are supporting with the frequency conversion equipment with high-temperature anticorrosion requirement.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model is provided with cable core, outside cable core, sets gradually metal tape lapped shielding layer 1, metal wire knitted screen 2, high stopband lapping layer 3 and outer jacket 4; Between cable core and metal tape lapped shielding layer 1, packed layer 5 is set; Cable core comprises that three main insulation cores 6 and 7, three main insulation cores 6 of three zero line insulated wire cores comprise first conductor 8, set gradually first insulating barrier 9 and second insulating barrier 10 outside first conductor 8; Three zero line insulated wire cores 7 comprise second conductor 11, outside second conductor 11, set gradually the 3rd insulating barrier 12 and the 4th insulating barrier 13.
