Abstract
The utility model discloses an EP rubber insulation and high-voltage-resistant flat cable. The cable comprises three conductors. An EP rubber insulation layer, a tin-coated copper wire braided shielding layer and a taped layer are successively arranged outside each conductor. The three conductors wrapped by the taped layers are spaced at equal intervals in a parallel manner on the same plane to form a cable core. A chlorinated polyethylene sheath layer is molded outside the cable core through plastic extrusion. A frame, braided by a steel wire to be channel-shaped, is disposed inside the chlorinated polyethylene sheath layer and is positioned outside the conductors wrapped by the taped layers. An anticorrosion layer is arranged outside the sheath layer. The EP rubber insulation and high-voltage-resistant flat cable has a reasonable structure, and through adoption of the frame outside the conductors of the cable, mechanical strength of the cable is effectively improved. Moreover, through a design of heat radiation holes, the heat radiation efficiency is improved, normal transmission of power and communication is guaranteed and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to flat cable, relates in particular to a kind of ethylene propylene rubber insulated high pressure resistant flat 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.
Round relatively cable, flat cable more has advantages such as the installing space of saving and cost, and under the identical situation of heart yearn radical, its bending radius is littler than round cable, but in the operational environment of reality, have such as industries such as metallurgy, electric power, petrochemical industry and to move in the specific (special) requirements occasion such as anticorrosion, the tensile strength of cable does not often reach requirement, influences the normal transmission of electric power and communication.
The utility model content:
At above-mentioned technical problem, the purpose of this utility model provides a kind of ethylene propylene rubber insulated high pressure resistant flat cable, has improved the mechanical strength of cable, can conform better.
The technical solution of the utility model is as follows:
Ethylene propylene rubber insulated high pressure resistant flat cable, comprise three conductors, it is characterized in that: described three conductors all are provided with ethylene propylene rubber insulated layer, tinned copper wire woven shield, lapping layer outward successively, three conductors of parcel lapping layer parallel interval distribution at grade constitute cable core, the outer extrusion moulding of cable core has the chlorinated polyethylene sheath layer, be provided with the conductor outside that skeleton that braided steel wire becomes the passage shape is positioned at the parcel lapping layer in the chlorinated polyethylene sheath layer, restrictive coating also is provided with corrosion-inhibiting coating outward.
Described ethylene propylene rubber insulated high pressure resistant flat cable is characterized in that: also be provided with louvre in the chlorinated polyethylene sheath layer in the described skeleton outside.
The utility model has the advantages that:
The utility model reasonable in design by be provided with skeleton outside cable conductor, improves the mechanical strength of cable effectively, and in addition, the design of louvre improves radiating efficiency, ensures the normal transmission of electric power and communication, increases the service life.
