Abstract
The utility model discloses a mobile phone transmission tower light-duty electric cable comprising a center conductor, three surrounding conductors, wherein each of the center conductor and the surrounding conductors is orderly coated with an electrically semi-conductive layer, a cotton yarn woven layer, and a ceramic silicone rubber insulating layer; thus a center insulating wire core and three surrounding insulating wire cores are formed; the center conductor is formed by twisting alloy wires into a bundle with a phosphatized steel wire at the center; the three surrounding insulating wire cores are twisted into a bundle with the center insulating wire core at the center and therefore a cable core is formed; a spiral winding plastic tube and a protection layer which is molded by extruding foamed plastic are arranged outside the cable core, and the protection layer which is molded through plastic extrusion is integrated with the plastic tube. The mobile phone transmission tower light-duty electric cable is characterized in that reasonable structural design and good compactness are realized, the electric cable is improved in tensile strength and warp resistant performance due to the arrangement of the phosphatized steel wire in the center conductor, the plastic tube and the protection layer which is made of a foamed material are arranged outside the cable core, and therefore the electric cable can be effectively reduced in total weight, the electric cable can be mounted and laid conveniently, and the cost is saved.
Description
Technical field:
The utility model relates to communication cable, relates in particular to a kind of mobile phone launching tower lightweight cable.
Background technology:
In communication system, communication cable is mainly used in the AC/DC configuration circuit, cable duct, and the wire clamp in the communication central office and irrigation canals and ditches, power distribution station, in mobile phone launching tower and other mobile devices.
The cable of mobile phone launching tower occasion use at present, in the situation that internal structure is basically identical, outside is mostly adopted and is extruded with inner restrictive coating, external sheath layer structure, make the outside diameter of cable larger, mounting and installation is inconvenience quite, and in addition, the warp resistance performance of cable is relative with flexibility poor at present.
The utility model content:
In order to make up the prior art problem, the purpose of this utility model is to provide a kind of mobile phone launching tower lightweight cable, simple in structure, has improved warp resistance performance and the flexibility of cable, has also reduced the external diameter after the cable cabling simultaneously, is conducive to mounting and installation.
The technical solution of the utility model is as follows:
Mobile phone launching tower lightweight cable, comprise center conductor, three peripheral conductors, it is characterized in that: described center conductor, three peripheral conductors are coated with respectively semi-conductive layer outward successively, cotton braid, the ceramic silicone rubber insulation layer forms the central insulation core, insulated wire cores around three, described center conductor adopts B alloy wire stranded bunchy centered by the phosphatization steel wire to form, around described three, insulated wire cores stranded bunchy centered by the central insulation core forms cable core, cable core is provided with the plastic tube of spiral winding outward, the protective layer of foamed plastic extrusion moulding, protective layer is in aggregates through extrusion moulding and plastic tube.
Described mobile phone launching tower lightweight cable is characterized in that: the cotton braid that described cotton braid employing diameter is 0.65mm reticulates formation, and count is not less than 86%.
Described mobile phone launching tower lightweight cable is characterized in that: the plastic tube of described spiral winding is wound around spacing and is not more than 1.5mm.
The utility model has the advantages that:
The utility model reasonable in design, compactedness is good, by center conductor, being provided with the phosphatization steel wire; promote the tension warp resistance performance of cable; the protective layer that cable core is provided with plastic tube, expanded material outward can effectively reduce the cable total weight, is convenient to mounting and installation, cost-saving.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Mobile phone launching tower lightweight cable, comprise center conductor 1, three peripheral conductors 2, center conductor 1, three outer semi-conductive layers 3 that are coated with successively respectively of peripheral conductor 2, cotton braid 4, ceramic silicone rubber insulation layer 5 forms the central insulation core, insulated wire cores around three, center conductor 1 adopts B alloy wire 1-1 stranded bunchy centered by phosphatization steel wire 1-2 to form, around three, insulated wire cores stranded bunchy centered by the central insulation core forms cable core, cable core is provided with the plastic tube 5 of spiral winding outward, the protective layer 6 of foamed plastic extrusion moulding, protective layer 6 is in aggregates through extrusion moulding and plastic tube 5.
Cotton braid 2 employing diameters are that the cotton braid of 0.65mm reticulates formation, and count is not less than 86%.
The plastic tube 5 of spiral winding is wound around spacing and is not more than 1.5mm.
