Abstract
The utility model discloses a metallic shielded power cable, comprising a plurality of conductors with the cross section being fan-shaped and one conductor with the cross section being circular, which are all wrapped with an insulation layer, wherein inside the insulation layer there is provided a circle of netty framework knitted by semiconductors, and the outside of the plurality of conductors with the cross section being fan-shaped and the conductor with the cross section being circular wrapped by the insulation layer are wrapped in order with a bandage layer, an inner sheath layer, a shielding layer and an outer sheath layer. The metallic shielded power cable is simple in structure, and is configured to arrange a circle of netty framework knitted by semiconductors, thereby enabling the electromagnetic interference resistance of the cable to be effectively increased and the strength of the insulation layer of the cable to be enhanced; and the cable is provided with equalized potential, thereby enabling the characteristic of power supply quality to be improved.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of metallic shield power cable.
Background technology:
Power cable (power cable) is used to transmit and distribute the cable of electric energy.Be usually used in the underground electrical network in city, power station lead line, industrial and mining enterprises in-line power and cross river, the submarine transmission line in sea excessively.In power circuit, the shared proportion of cable increases just gradually.Power cable is in order to transmit and to distribute the cable product of high-power electric energy, comprising 0-500KV and above various electric pressure, the power cable of various insulation in the main line of electric power system.
Previous power cable, the power cable of in rated voltage 0.6/1kv and following AC and DC power circuit, using, common anti-electromagnetic interference performance as transmission of electric energy a little less than, the isolation layer intensity of cable is not enough, cable conductor is often impaired easily.
The utility model also has anti-thunderbolt and balanced current potential, improves the characteristic of power supply quality except that the electricity characteristic that possesses the common power of moulding cable, more be applicable to computer center, aviation boat Surveillance center, intelligent building etc.
The utility model content:
At the prior art problem, the purpose of this utility model provides a kind of metallic shield power cable, is applicable in rated voltage 0.6/1kv and the following AC and DC power circuit to make transmission of electric energy usefulness, is specially adapted to have the place of precision electronic device.
The technical solution of the utility model is as follows:
The metallic shield power cable, comprise that several cross sections are that fan-shaped conductor, a cross section are circular conductor, it is characterized in that: described several cross sections are that fan-shaped conductor, a cross section are circular conductor outer wrapping insulating barrier, be provided with a circle semiconductor in the described insulating barrier and weave webbed skeleton, the several cross sections behind the wrap insulate layer are that fan-shaped conductor, a cross section are enclosed with belting layer, inner restrictive coating, screen, external sheath layer outward successively for circular conductor.
Described metallic shield power cable is characterized in that: described insulating barrier, inside and outside restrictive coating material adopt polyvinyl chloride.
Described metallic shield power cable is characterized in that: described screen adopts the wrapped formation of copper strips.
The utility model has the advantages that:
Of the present utility model simple in structure, in the insulating barrier of cable, be provided with a circle semiconductor and weave webbed skeleton, the anti-electromagnetism that has effectively strengthened cable is disturbed performance, makes the isolation layer intensity of cable improve, and the while cable has balanced current potential, improves the characteristic of power supply quality.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
