Description

A kind of electromagnetism interference cable

Technical field

The utility model is related to technical field of electric wires and cables, specifically a kind of electromagnetism interference cable.

Background technology

Some Partial Discharge Detection equipment have special requirement to power supply, do not allow to be disturbed by extraneous, detecting system Supply line requires to be strictly separated with circuit such as the other equipment of factory, illuminations it is desirable to preferably with single cable duct, but Some places are limited to various factors, and it is very difficult for excavating cable duct.

Content of the invention

For defect or deficiency present in above-mentioned prior art, technical problem to be solved in the utility model is to provide A kind of electromagnetism interference cable, to solve the problems, such as or to improve current.In order to reach object above, the utility model is taken as follows Technical scheme：

A kind of electromagnetism interference cable, including core it is characterised in that described core the inside is conductor, described conductor Outside is coated with inner insulating layer, laminated polyester film, screen layer, external insulation layer successively, and the core described in three strands is combined, and Coat filler, inner liner, armouring tape, sheath outside successively.

Further, conductor is the stranded aluminium alloy conductor of molded line of the roll-forming of 2+7.

As one kind preferably, inner insulating layer material is XLPE, and external insulation layer material is PE.

As one kind preferably, screen layer is proof copper-wire braided.

As one kind preferably, sheath material is PVC.

The beneficial effect of the technical program is：

（1）Cable duct can not individually be excavated, quantities is much smaller；

（2）The interference of electromagnetic wave can reliably be shielded.

Brief description

In order to be illustrated more clearly that the technical scheme in the utility model embodiment, below will be to required in embodiment description Accompanying drawing to be used is briefly described.

Fig. 1 is a kind of structural representation of electromagnetism interference cable；

Fig. 2 is conductor structure schematic diagram.

In figure numeral represents：

A, core；1st, sheath；2nd, armouring tape；3rd, inner liner；4th, filler；5th, external insulation layer；6th, screen layer；7th, polyester Film layer；8th, inner insulating layer；9th, conductor.

Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe.

A kind of electromagnetism interference cable, including core A it is characterised in that described core A the inside is conductor 9, described leads It is coated with inner insulating layer 8, laminated polyester film 7, screen layer 6, external insulation layer 5 successively, the core A combination described in three strands outside body 9 Together, and outside filler 4, inner liner 3, armouring tape 2, sheath 1 are coated successively.

Conductor（9）The molded line of the roll-forming for 2+7 is stranded, and using the aluminium alloy conductor of the soft state of AA8030, design is selected 50mm2, structure, as shown in Fig. 2 smooth surface, is not in the burr that compact conductor has, when electric energy transmits, to interference letter Number do not have enlarge-effect.

Using continuously extruding, inner insulating layer 8 material is XLPE for insulation（Organosilane crosslinked polyethylene）, the sheath material of split-phase shielding Material, being also adopted by XLPE, because not having vapor crosslinking, being effectively equivalent to extrude PE（Polyethylene）.

The shielding of cable adds the structure of copper wire split-phase shielding using steel-tape armouring, because steel band is preferable magnetic screen material Material, copper is preferable electrical shielding material, and the combination of bi-material can preferably prevent electromagnetic interference, and screen layer 6 is braid shielded, More than 90%, unidirectional coverage rate is not less than 0.7 to count, and material adopts tin plating soft copper silk braiding, and line footpath is 0.165mm.

It is provided with one layer of external insulation layer 5 outside screen layer 6, using PE insulation, prevent interference signal from sealing in another phase.

For preventing braided wires during proof copper-wire braided shielding from stabbing insulating barrier, indulge between insulating barrier 8 and screen layer 6 and wrapped one layer Laminated polyester film 7, laminated polyester film 7 has good electrical property and mechanical performance, and thickness is 0.04～0.05mm.

Sheath 1 material is PVC, has fire resistance.

It should finally be noted above example is only the more representational example of the utility model.Obviously the utility model It is not limited to above-described embodiment, can also have many deformation.Every according to technical spirit of the present utility model to above example institute Any simple modification, equivalent variations and the modification made, is all considered as belonging to protection domain of the present utility model.
