Abstract
The utility model discloses a frequency conversion power cable. A conductor of the frequency conversion power cable employs soft copper conductors, the conductor is extruded by a polythene insulation layer to form an insulation core, a plurality of insulation cores and filling rope are stranded to form a cable core, the cable core is externally wrapped by a polyester belting layer, the belting layer is provided with a shielding layer braided by copper wire, the shielding layer is respectively provided with an isolation sleeve layer, an armor layer and an outer sheath layer from inside to outside, and the isolation sleeve and the outer sheath are respectively extruded by employing halogen free low smoke polyolefin material. The frequency conversion power cable employs two different types of shielding materials which have complementation effects on electromagnetic wave shielding, so a shielding effect can be better, moreover, the steel band interlock armor further has additive total shielding effects. The cable further has relatively strong voltage shock resistance and can stand high speed frequent frequency conversion pulse voltage, so good protection effects for a frequency conversion electric appliance are realized.
Description
Technical field
Utility model relates to a kind of power cable, and particularly a kind of frequency conversion power cable belongs to technical field of electric wires and cables.
Background technology
Recent two decades comes frequency control motor that very big development is arranged at home and abroad, and annual growth slightly surpasses 10%, and the DC Transmission annual growth is 3-4%.Variable-frequency motor has more advantage, and few as the equipment investment expense, simple in structure, volume is little, and cost is low, and is energy-conservation, and speed adjustable range is big, has the characteristic of permanent power, permanent rotating speed, and is easy to use, and capacity is big etc.Therefore currently also use widely in industrial aspect such as metallurgy, mine, railways, equally also widely apply at household electrical appliance recently, this just gets more and more to the demand of frequency-changing cable.
The utility model content
The utility model purpose provides a kind of power cable, particularly LSOH anti-flaming pliability frequency conversion power cable.Belong to technical field of electric wires and cables.
Scheme of the present utility model is as follows: a kind of frequency conversion power cable, its conductor adopts the soft copper conductor, extrude the polyethylene insulating barrier on the described conductor and constitute insulated wire cores, many eradication edge cores and gasket for packing twist together the formation cable core, the outer wrapped polyester belting layer of described cable core, the screen that adopts the copper wire braiding is set on the described belting layer, also arrange respectively from inside to outside on the described screen and isolate jacket layer, armour, external sheath layer, described separation sleeve and oversheath all adopt the low smoke, zero halogen polyolefine material to extrude.
Described armour adopts 0.5mm steel band lock armo.
The beneficial effects of the utility model:
1, the utility model cable adopts steel-tape armouring and copper wire shielding, is to have adopted two kinds of different shielding materials, plays certain complementation at electromagnetic wave shielding, and shield effectiveness will be better, and the steel band lock armo also plays the total shielding action of additivity simultaneously.
2, the utility model cable armouring adopts the thick steel band lock armo of 0.5mm, has improved the cable bending property, pliability is good, very easily lays.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, adopt copper conductor 1, crosslinked polyetylene insulated layer 2 is extruded on the conductor, and adopts vapor crosslinking; Six roots of sensation insulated wire cores twists together with less pitch then, simultaneously with gasket for packing 3 stranded formation cable cores, the outer wrapped polyester belting layer 4 of cable core, carry out copper wire woven shield 5 then, extrude low smoke, zero halogen polyolefin separation sleeve 6 successively, steel band lock armo layer 7 extrudes low smoke, zero halogen polyolefin external sheath layer 8.Two kinds of different shielding materials have been adopted in this practicality, play certain complementation at electromagnetic wave shielding, and shield effectiveness will be better, and the steel band lock armo also plays the total shielding action of additivity simultaneously.Cable has stronger proof voltage impact simultaneously, and the pulse voltage in the time of standing at a high speed frequently frequency conversion plays a good protection to frequency conversion electrical equipment.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
Claims (2)
1. frequency conversion power cable, it is characterized in that conductor adopts the soft copper conductor, extrude the polyethylene insulating barrier on the described conductor and constitute insulated wire cores, many eradication edge cores and gasket for packing twist together the formation cable core, the outer wrapped polyester belting layer of described cable core, the screen that adopts the copper wire braiding is set on the described belting layer, also arranges respectively from inside to outside on the described screen and isolate jacket layer, armour, external sheath layer, described separation sleeve and oversheath all adopt the low smoke, zero halogen polyolefine material to extrude.
2. a kind of frequency conversion power cable according to claim 1 is characterized in that described armour adopts the steel band lock armo.
