Abstract
The utility model discloses an armored metallic shielding variable-frequency power cable equipped with an inner steel tape. The armored metallic shielding variable-frequency power cable comprises main conductors and neutral conductors. The surfaces of main conductors and the surfaces of the neutral conductors are successively wrapped in XLPE insulating layers, asbestos filling layers, and metallic shielding layers. The three main conductors are arranged centrally symmetrically. The neutral conductors are placed between every two main conductors. The main conductors and the neutral conductors are twisted in a compound manner to form a cable core. The outer side of the cable core is successively wrapped in a cabling wrapping tape, an inner sheath, a copper wire shielding layer, a copper tape shielding layer, an isolating sleeve, a steel tape armoring layer, and a flame-retardant polyvinyl chloride outer sheath. The armored metallic shielding variable-frequency power cable uses a crosslinked polyethylene insulating layer and applies the asbestos filling layers, the isolating sleeve, and the steel tape armoring layer so as to achieve characteristics of a good insulating and shielding effect, low production cost, and a good isolating effect.
Description
Technical field
The utility model relates to the cable technology field, relates in particular to a kind of with interior steel-tape armouring metallic shield frequency-conversion power cable.
Background technology
Power electronic technology has entered the converter technique epoch at present, and converter technique is the alternating-current electric drive technology that integrates high frequency, high pressure and large electric current, and frequency conversion system is comprised of frequency converter, variable-frequency motor, control circuit.Efficient, energy-conservation and intelligentized characteristics that frequency converter has.The insulation shield effect of using in frequency conversion system in prior art is bad, and useful life is short, and the effect that is isolated from the outside is bad, needs to improve.
The utility model content
The utility model purpose is exactly in order to make up the defect of prior art, provides a kind of with interior steel-tape armouring metallic shield frequency-conversion power cable.
The utility model is achieved through the following technical solutions:
A kind of with interior steel-tape armouring metallic shield frequency-conversion power cable, include leading body and neutral conductor, the outside at described leading body and neutral conductor is surrounded by respectively XLPE insulating barrier, asbestos packed layer and metal screen layer successively, three leading body Central Symmetries are placed, be placed with neutral conductor between every two leading bodies, and adopt compound bundle strand to form cable core leading body and neutral conductor, be coated with successively stranding band, inner sheath, shielding layer of copper wires, copper strip shielding layer, separation sleeve, steel-tape armouring layer and flame-proof polyvinyl chloride oversheath in the cable core outside.
Described leading body and neutral conductor all adopt oxygen-free copper bar.
The utility model has the advantages that: the utility model is used crosslinked polyetylene insulated layer, and has increased asbestos packed layer, separation sleeve and steel-tape armouring layer, makes its insulation shielding better effects if, low cost of manufacture, and isolation effect is good.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of with interior steel-tape armouring metallic shield frequency-conversion power cable, include leading body 1 and neutral conductor 2, the outside at described leading body 1 and neutral conductor 2 is surrounded by respectively XLPE insulating barrier 3 successively, asbestos packed layer 4 and metal screen layer 5, three leading bodies, 1 Central Symmetry is placed, be placed with neutral conductor 2 between every two leading bodies 1, and adopt compound bundle strand to form cable core leading body 1 and neutral conductor 2, be coated with successively stranding band 6 in the cable core outside, inner sheath 7, shielding layer of copper wires 8, copper strip shielding layer 9, separation sleeve 10, steel-tape armouring layer 11 and flame-proof polyvinyl chloride oversheath 12.
Described leading body 1 and neutral conductor 2 all adopt oxygen-free copper bar.
Claims (2)
1. one kind with interior steel-tape armouring metallic shield frequency-conversion power cable, it is characterized in that: include leading body and neutral conductor, the outside at described leading body and neutral conductor is surrounded by respectively the XLPE insulating barrier successively, asbestos packed layer and metal screen layer, three leading body Central Symmetries are placed, be placed with neutral conductor between every two leading bodies, and adopt compound bundle strand to form cable core leading body and neutral conductor, be coated with successively the stranding band in the cable core outside, inner sheath, shielding layer of copper wires, the copper strip shielding layer, separation sleeve, steel-tape armouring layer and flame-proof polyvinyl chloride oversheath.
2. according to claim 1 with interior steel-tape armouring metallic shield frequency-conversion power cable, it is characterized in that: described leading body and neutral conductor all adopt oxygen-free copper bar.
