Abstract
The utility model discloses a special silicon rubber insulated variable frequency system power cable, which comprises conductors, wire cores, a covering tape, a shield layer and a sheath. The wire cores are arranged among the conductors wrapped by the covering tape, the covering tape is wrapped by the shield layer, and the shield layer is wrapped by the sheath. The wire cores are power wire cores. The special silicon rubber insulated variable frequency system power cable has fine flexibility, increases working temperature to 180 DEG C, increases product voltage resistance, also is high in heat resistance, superior in cold resistance, excellent in electric insulation, fine in aging resistance and fine in oil resistance, and is nontoxic and odorless.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of silicon rubber insulation frequency conversion system special electric power cable.
Background technology:
Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Electric wire mainly comprises bare wire, electromagnetic wire and electrical equipment and electrical insulated electric conductor, power cable, telecommunication cable and optical cable.
The utility model content:
The purpose of this utility model provides a kind of silicon rubber insulation frequency conversion system special electric power cable, has solved the frequency conversion power cable and can not adapt to operate as normal in hot environment.
The technical solution of the utility model is as follows:
Silicon rubber insulation frequency conversion system special electric power cable comprises conductor, core, band, screen, sheath, it is characterized in that being provided with core in the described conductor conductor outer wrapping band, band outer wrapping screen, screen outer wrapping sheath.
Described core is the power core.
The material that the utility model adopted is as follows:
(1) conductor.Conductor material is selected high-quality annealing oxygen-free copper, phenomenons such as conductive surface light, non-oxidation, burr for use.
(2) insulation.Insulating material is selected exotic material for use, and requires to have excellent insulation electrical performance, for satisfying these performances and requirement, selects the silicon rubber insulation material.The working temperature of silicon rubber is 180 ℃, and silicon rubber insulation has very high thermal endurance, excellent cold resistance, excellent electric insulation performance, good aging properties, excellent oil resistance, and nontoxic odorless, is good environment-friendly materials.
(3) shielding material
Shielding material according to different requirements can select copper wire braiding for use, copper strips is wrapped, copper wire braiding copper strips is wrapped and copper wire is dredged wrapped around copper strips.
(4) cable element.Take 3 little cores are placed on respectively the embedding crack of 3 big cores, wherein, the adjustment of laying tension is very crucial, by improving actinobacillus device, guarantees core laying tension unanimity, and the cable core of emitting like this is tight, rounding.Packing material should be consistent with the working temperature of cable, and should be compatible with contactant.Outer wrapped one or more layers band of cable core is tightened, and prevents that cable core is loose in the laid processes.Have the cable of fire-retardant requirement should adopt fire proofing to fill, and fire-retardant band is wrapped tightens.
(5) sheath.According to environment for use and cable normal operating temperature, select the silicone rubber jacket material, because oversheath requires to have certain mechanical property, common silastic material mechanical property is relatively poor, especially tear resistance is poor, can not satisfy the normal mounting operation of cable,, select for use tension to tear the silicone rubber jacket material and can satisfy serviceability through test, checking.
Advantage of the present utility model:
The utlity model has good pliability, make the working temperature of cable bring up to 180 ℃ Celsius, improve the voltage-resistent characteristic of product simultaneously, also have very high thermal endurance, excellent cold resistance, excellent electric insulation performance, good aging properties, excellent oil resistance, and nontoxic odorless.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Silicon rubber insulation frequency conversion system special electric power cable comprises conductor 1, core 2, band 3, screen 4, sheath 5, is provided with core 2 in the described conductor 1, conductor 1 outer wrapping band 2, band 3 outer wrapping screens 4, screen 4 outer wrapping sheaths 5.
Described core 2 is the power core.
