Abstract
The utility model discloses a power cable with silicone insulating layers and silicone flat sheath layers. The power cable comprises a plurality of alloy conductors, wherein the alloy conductors are parallelly placed on the same plane, and each of the alloy conductors is formed by twisting 24 to 49 alloy wires with the diameter of 0.20 to 0.25mm into a bundle; tin plated layers are formed on the outer sides of the alloy conductors; each alloy conductors is respectively wrapped by a conductor shielding layer and an insulating layer sequentially; the thickness of each insulating layer is 0.5 to 1.0mm; the insulating layers are connected into a whole through connection belts; steel belts are arranged in the connection belts; and flat sheath layers are formed outside the alloy conductors wrapped by the insulating layers through extrusion molding. According to the power cable, the insulating layers and the sheath layers are made of tear-resistant silicone, so that the power cable has high cold resistance, oil resistance, wear resistance and tear resistance; and the steel belts are arranged in the connection belts among the insulating layers, so that the tensile performance of the power cable is improved, and the service life of the power cable in the severe environment is prolonged.
Description
Technical field:
The utility model relates to control cables, relates in particular to a kind of silicon rubber insulation and sheath Flat power cable.
Background technology:
Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, 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.
Relatively round cable, flat cable more has the advantages such as the installing space of saving and cost, and in the situation that the heart yearn radical is identical, its bending radius is less than round cable.Flat cable has in the mobile specific (special) requirements occasion such as anticorrosion in industries such as ac rated voltage 6kv ~ 10kv metallurgy, electric power, petrochemical industry, the mechanical strength that work moved or fixedly laid electrical appliance Instrument connection or signal-transmitting cable does not reach requirement, thereby cause transmission of information to interrupt, cause huge economic loss.
The utility model content:
In order to remedy the deficiencies in the prior art, the utility model purpose provides a kind of silicon rubber insulation and sheath Flat power cable, is applicable to do, and has solved the relatively poor defective of cable tensile strength in having adverse circumstances.
Technical solutions of the utility model are as follows:
Silicon rubber insulation and sheath Flat power cable, comprise several alloy conductors, it is characterized in that: described several alloy conductors are parallel to each other on same plane and place side by side, it is that the stranded bunchy of 0.20 ~ 0.25mm B alloy wire consists of that several alloy conductors all adopt 24 ~ 49 diameters, several alloy conductors outside is respectively equipped with tin coating, several alloy conductors wrap up respectively conductor shield outward successively, insulating barrier, the thickness of insulating barrier is 0.5 ~ 1.0mm, link into an integrated entity by related between the insulating barrier, be provided with steel band in related, the outer extrusion molding of several alloy conductors of wrap insulate layer has pancake restrictive coating.
Described silicon rubber insulation and sheath Flat power cable is characterized in that: described insulating barrier, restrictive coating adopt tear-proof silicon rubber.
The utility model has the advantages that:
The utility model adopts tear-proof silicon rubber at insulating barrier and restrictive coating, so that cable has good cold-resistant, grease proofing, anti-wear performance, tear resistance, be provided with steel band in related between the insulating barrier of this outer cable, the tension that has improved cable rises performance, has strengthened the useful life of cable in adverse circumstances.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
Referring to Fig. 1:
Silicon rubber insulation and sheath Flat power cable, comprise several alloy conductors 1, several alloy conductors 1 are parallel to each other on same plane and place side by side, it is that the stranded bunchy of 0.20 ~ 0.25mm B alloy wire consists of that several alloy conductors 1 all adopt 24 ~ 49 diameters, several alloy conductors 1 outside is respectively equipped with tin coating 2, several alloy conductor 1 outer difference are wrapped up conductor shield 3 successively, insulating barrier 4, the thickness of insulating barrier 4 is 0.5 ~ 1.0mm, link into an integrated entity by related 5 between the insulating barrier 4, be provided with steel band 6 in related 5, several alloy conductors 1 outer extrusion molding of wrap insulate layer 4 has pancake restrictive coating 7.
Claims (2)
