Abstract
The utility model discloses an anti-extrusion type frequency converter cable comprising three alloy conductors, each of which has a sector-shaped cross section. Each of the three alloy conductors is sequentially wrapped by a conductor shielding layer and an insulation layer to form an insulation core. The insulation cores are disposed in an anti-extrusion layer in an extrusion-molded manner to form a cable core. A ring of a net-shaped skeleton formed by braiding steel wires is disposed in the anti-extrusion layer. An outer side of each of the cable core is sequentially wrapped by a taped covering, a shielding layer, and a sheath layer. The anti-extrusion type frequency converter cable is advantageous in that the structure is simple, and the cable core conductor is disposed in the anti-extrusion layer in an extrusion-molded manner, and the anti-external extrusion capability of the cable can be improved; the cable has the strong anti-voltage surge performance, and the cable can bear the pulse voltage during the frequency conversion; the ability of the cable of effectively eliminating the electromagnetic interference is strong, therefore the noise of the frequency conversion motor can be reduced, and the stability of the system can be guaranteed.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of anti-extrusion type converter cable.
Background technology:
The insulating material that general frequency-changing cable adopts mainly is hard ethylene-propylene rubber and crosslinked polyethylene, and the electric property of the two is very superior, has equipment energy-conservation to pursue, and reduces equipment attrition, the extension device life-span.The use of frequency conversion equipment is increasing to the demand of supporting with it private cable (calling frequency-changing cable in the following text), and specification requirement is also more and more higher.Because the place mainly laid of frequency-changing cable mostly is in the cabin so that frequency-changing cable to lay the space less, require the external diameter, weight, bending radius etc. of cable on the basis of guaranteed performance as far as possible little.
Original frequency-changing cable cable core often is squeezed, bending is so that the cable core fracture, and electric power transfer is interrupted, and needs often to change.
The utility model content:
In order to remedy the deficiencies in the prior art, the purpose of this utility model provides a kind of anti-extrusion type converter cable, is used as service cable or major loop and connects under frequency-changing control system, and anti-extraneous extrusion performance is superior, effectively protects cable core injury-free.
The technical solution of the utility model is as follows:
Anti-extrusion type converter cable, it is characterized in that: comprise that the cross section is three fan-shaped alloy conductors, described three alloy conductors all are enclosed with conductor shield outward successively, insulating barrier consists of insulated wire cores, insulated wire cores is distributed in the resistance to compression layer through extrusion moulding and consists of cable core, also be provided with the webbed skeleton of a circle braided steel wire in the resistance to compression layer, the cable core outside is enclosed with lapping layer, screen, restrictive coating successively.
Described anti-extrusion type converter cable is characterized in that: it is crosslinked polyethylene that described insulating barrier adopts material.
The utility model has the advantages that:
The utility model is simple in structure, cable core conductor extrusion moulding is placed in the resistance to compression layer, improved the anti-extraneous extrusion capability of cable, this outer cable also has stronger proof voltage impact, the pulse voltage in the time of standing frequency conversion, effectively eliminate electromagnetic interference capability strong, reduce the advantage that the variable-frequency motor noise guarantees the stability of a system.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Anti-extrusion type converter cable, comprise that the cross section is three fan-shaped alloy conductors 1, three alloy conductor 1 outer conductor shield 2, insulating barrier 3 formation insulated wire cores of all being enclosed with successively, insulated wire cores is distributed in the resistance to compression layer 4 through extrusion moulding and consists of cable core, also be provided with the webbed skeleton 5 of a circle braided steel wire in the resistance to compression layer 4, the cable core outside is enclosed with lapping layer 6, screen 7, restrictive coating 8 successively.
It is crosslinked polyethylene that insulating barrier 3 adopts material.
