Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated:
cable as shown in Figure 1 comprises cable core, is coated on the outer sheath of cable core.Wherein, cable core mainly is made up of three power lines that are used to transmit 1 and a control line 2 that is used for transmission signals.Following elder generation describes the structure of power line and control line:
every power line 1 by conductor 11, wrappedly form at mica tape fireprotection layer 12 on the conductor 11 and the low smoke halogen-free flame-retardant polyolefin insulating barrier 13 of extrusion molding on mica tape fireprotection layer 12.Wherein, conductor 11 is closed by many soft copper skein silks and forms, and mica tape fireprotection layer 12 adopts two-sided plasticising synthetic mica tape, has fire protecting performance preferably.
every control line 2 by at least one pair of twisted wire 21, wrappedly form at internal shield on the twisted pair wire 21 22 and wrapped outer shielding layer 23 on internal shield 22; Wherein, Twisted pair wire 21 is by two mutually stranded forming of single line, and every single line is made up of many mutually stranded conductor 211 and the low smoke halogen-free flame-retardant polyolefin insulating barriers 212 of extrusion molding on conductor 211 of soft copper silk.Described internal shield 22 adopts high strength aluminium foil wheat to draw wrapped forming, and described outer shielding layer 23 is formed by the copper wire braiding.
Conductor in conductor 11 in
said power 1 and the control line 2 in every single line is 5 types of conductor structures; In the present embodiment; Conductor 11 external diameters in the power line 1 are greater than in the control line 2 external diameter of conductor 211 in the every single line, and promptly the mutually stranded soft copper silk of the conductor in the power line 1 11 is more.
described sheath comprises wrapped at the low-smoke bittern-free highly fire-proof band 31 on the cable core, the extrusion molding low-smoke bittern-free highly fire-proof polyolefin outer jacket 32 on low-smoke bittern-free highly fire-proof band 31.
In
present embodiment, between cable core and sheath, also be filled with filler and form packed layer 33, described filler is the low-smoke bittern-free highly fire-proof polyolefin.
