Abstract
The utility model discloses a lightweight anti-extrusion flat power cable. The lightweight anti-extrusion flat power cable comprises three conductor sets, and each conductor set is formed by arranging three conductors into a cylindrical shape, wherein the three conductors are wrapped with the irradiation crosslinking polyolefin insulating layers respectively, and the cross-section of each conductor is fan-shaped. A tightening layer, an anti-extrusion layer, an inner shielding layer and an outer shielding layer are wrapped on the outside of each conductor set orderly, an expanded plastic layer is arranged between the inner shielding layer and the outer shielding layer, and a protection layer is wrapped on the outside of the outer shielding layer. The three conductor sets wrapped with the protection layer respectively are distributed in a same plane at intervals to form a cable core, and a flat irradiation crosslinking polyethylene sheath layer is in extrusion molding on the outside of the cable core. The lightweight anti-extrusion flat power cable of the utility model is novel in structure design, the insulating wire cores of which the cross-sections are fan-shaped are arranged into the cylindrical shape to form the cable core, and the structures, such as the tightening layer, the anti-extrusion layer, etc., are arranged on the outside of the cable core, so that the cable is good in structure compactness and small in outer diameter, the expanded plastic layers enable the overall weight of the cable to be reduced, and the cable is convenient to install and lay. In addition, the cable also has the excellent performance, such as the wear resistance, the insulating property, the mechanical property, etc.
Description
technical field:
The utility model relates to flat cable, relates in particular to the anti-extrusion type flat of a kind of lightweight power cable.
background technology:
Existing flat cable extrudes sheath and forms after being arranged in parallel by three or four insulated wire cores, and the structural compactness of cable, sheath wearing and tearing and the poor phenomenon of insulation property, cause cable short useful life, and user loses large problem.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide the anti-extrusion type flat of a kind of lightweight power cable, has improved construction of cable compactedness, sheath wearing and tearing and insulation property, and mounting and installation is convenient.
The technical solution of the utility model is as follows:
The anti-extrusion type flat of lightweight power cable, comprise three conductor groups, it is characterized in that: three described conductor groups are by three coated irradiation crosslinked polyolefin insulating layers, cross section is that fan-shaped conductor surrounds cylindrical formation, each conductor group is all coated with successively and tightens layer outward, anti-extrusion layer, internal shield, outer shielding layer, internal shield, between outer shielding layer, be provided with foamed plastic layer, outer shielding layer is coated with protective layer, three conductor groups of coated protective layer are formation cable core spaced apart at grade, the outer extrusion moulding of cable core has the IXPE restrictive coating of flat.
The anti-extrusion type flat of described lightweight power cable, is characterized in that: in described anti-extrusion layer, along annular space, be distributed with some cordage, the diameter of cordage is not more than 1.5mm.
The anti-extrusion type flat of described lightweight power cable, is characterized in that: the described layer of tightening adopts high temperature resistant polyurethane tape to adhere to the overlapping wrapped formation in rear flank in synthetic mica tape, and the wrapped rate of putting up is not less than 12%.
The utility model has the advantages that:
The utility model structural design is novel, by cross section, play fan-shaped insulated wire cores and surround cylindrical formation cable core, cable core is provided with structures such as tightening layer, anti-extrusion layer outward and makes construction of cable compactedness good, external diameter is little, foamed plastic layer has reduced the overall weight of cable, be convenient to mounting and installation, in addition, cable also has good anti-wear performance, insulation property, mechanical performance etc.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to Fig. 1:
The anti-extrusion type flat of lightweight power cable, comprise three conductor groups, three conductor groups are by three coated irradiation crosslinked polyolefin insulating layers 2, cross section is that fan-shaped conductor 1 surrounds cylindrical formation, each conductor group is all coated with outward successively tightens layer 3, anti-extrusion layer 4, internal shield 5, outer shielding layer 6, internal shield 5, between outer shielding layer 6, be provided with foamed plastic layer 7, outer shielding layer 6 is coated with protective layer 8, three conductor groups of coated protective layer 8 are formation cable core spaced apart at grade, the outer extrusion moulding of cable core has the IXPE restrictive coating 9 of flat.
In anti-extrusion layer 4, along annular space, be distributed with some cordage 10, the diameter of cordage 10 is not more than 1.5mm.
