Abstract
The utility model discloses a silicone rubber insulated-sheathed power cable fine in property, which comprises a cable core set formed by a plurality of cable cores. Each cable core consists of a cable core conductor and an insulating layer sequentially from inside to outside, a nonwoven lining layer is arranged on the periphery of the cable core set, an inner silicon rubber sheath is arranged on the outer periphery of the non-woven lining layer, a metal wire woven armor is arranged on the outer periphery of the inner sheath, and an outer silicon rubber sheath is arranged on the surface of the metal wire woven armor. Since the insulating layer, the inner sheath and the outer sheath are all made of silicon rubber, insulating performance of the cable is greatly improved, mould proofing performance of the cable is greatly improved, and thereby service life of the cable is prolonged, and the power cable is quite suitable for tropical or humid tropical operation environments. In addition, by means of the structure of the metal wire woven armor, tensile resistance of the cable is improved, and a function of electromagnetic shielding can be achieved. The power cable has the advantages of flame retarding, irradiation resistance, high temperature resistance, oil proofing and the like.
Description
Technical field
The utility model relates to a kind of cable, specifically is a kind of silicon rubber insulation silicone rubber jacket power cable.
Background technology
But all do not have unified technical specification at present for the special cable that has a large capacity and a wide range at present, each enterprise does things in his own way, and the construction of cable dimensional requirement of manufacturing, the material of use and requirement, electric pressure, environment for use temperature, specification cross section, use occasion or the like be disunity all; Very lack of standardization; Bring very big trouble for user's selection and use, and owing to do not have country and industry standard, product requirement is lack of standardization; Product quality is very different; There are no laws to abide by in these cable market surpervisions, and a large amount of defective or inferior cables flood market, and are not merely the user and have brought unnecessary economic loss; Also for the equipment safety operation that uses cable has brought very big hidden danger, the normal operation of electrical control equipment, electric power system and the safety of personal property in serious threat.
At present, the fungicidal properties of many cables is poor, can not adapt to the operational environment of the torrid zone or humid tropics, thereby has had a strong impact on the useful life of cable.
The utility model content
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of anti-irradiation, silicon rubber insulation silicone rubber jacket power cable that resistance and high temperature resistance property is good.
To achieve these goals, the technical scheme below the utility model adopts:
The silicon rubber insulation silicone rubber jacket power cable that performance is good; Include the core group that a plurality of cores constitute; Each core is to be made up of core conductor, insulating barrier from inside to outside successively, and said core group outer periphery has the nonwoven fabrics inner covering, and the periphery of nonwoven fabrics inner covering is provided with the silicon rubber inner sheath; The periphery of inner sheath is provided with the metal wire knitted armouring, and the surface of said metal wire knitted armouring is provided with the silicon rubber oversheath; Wire in the said metal wire knitted armouring adopts zinc-coated wire or copper wire or tinned copper wire, aluminium wire or aluminum-alloy wire.
Said insulating barrier is to adopt silastic material to extrude to form.
Be provided with filler between said a plurality of core, filler is the non-absorbent material of adhesion core insulating barrier.
Said core is provided with five, and five cores are to be made up of three big circular cores and two small circular cores.
The beneficial effect of the utility model: because insulating barrier, inner sheath and oversheath have adopted silastic material; Insulation property have not only been improved; And improve the fungicidal properties of cable greatly, thus prolonged the useful life of cable, be fit to very much the operational environment of the torrid zone or humid tropics; Owing to adopt the version of metal wire knitted armouring, not only improved the resistance to tension of cable, but also had the function of electromagnetic shielding; The utility model also has characteristics such as fire-retardant, anti-irradiation, high temperature resistant and oil resistant.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, core conductor; 2, insulating barrier; 3, filler; 4, nonwoven fabrics inner covering; 5, small circular core; 6, inner sheath; 7, big circular core; 8, metal wire knitted armouring; 9, oversheath.
Embodiment
As shown in Figure 1; The silicon rubber insulation silicone rubber jacket power cable that performance is good includes three big circular cores 7 and two core groups that small circular core 5 constitutes, and each core is to be made up of core conductor 1, insulating barrier 2 from inside to outside successively; Said core group outer periphery has nonwoven fabrics inner covering 4; The periphery of nonwoven fabrics inner covering 4 is provided with silicon rubber inner sheath 6, and the periphery of inner sheath 6 is provided with metal wire knitted armouring 8, and the surface of said metal wire knitted armouring 8 is provided with silicon rubber oversheath 9; Wire in the said metal wire knitted armouring 9 adopts zinc-coated wire or copper wire or tinned copper wire, aluminium wire or aluminum-alloy wire.Insulating barrier 2 is to adopt silastic material to extrude to form.
Be provided with filler 3 between five cores, filler 3 is the non-absorbent material of adhesion core insulating barrier.
Rated voltage 0.6/1kV that the utility model is adapted at using under the hot environment occasion and following silicon rubber insulation silicone rubber jacket power cable.The rated voltage of so-called cable is cable design, use and carry out the reference voltage that electrical performance test is used.Rated voltage is represented with U0/U.U0 represent arbitrary main insulation conductor and " " voltage effective value between (metallic shield, metallic sheath or surrounding medium); U is the voltage effective value between any two phase conductors of multicore cable or single-core cable system.In AC system, the rated voltage of cable should equal to use the nominal voltage of the system of cable at least, and this condition all is suitable for U0 and U value; In direct current system, the normal voltage of this system should be not more than 1.5 times of rated voltage for cable.The operating voltage of system allows to surpass for a long time 10% of this nominal voltage of a system, if the rated voltage of cable equals the nominal voltage of this system at least, then cable can use under the operating voltage that is higher than rated voltage 10%.
