Embodiment
With reference to shown in Fig. 1, a kind of improved cable, it includes several the first conductors, is wrapped on the outside of several first conductors
Cover inner restrictive coating 1 and form cable core, petroleum jelly 2 is filled between the first conductor and inner restrictive coating 1；Inner restrictive coating 1 is orderly arranged outside each
There are alkali-free glass fibre belt 3, metal sheath layer and external sheath layer 4.
The metal sheath layer includes inner metal layer 5, outer metal level 6 and the company of connection inner metal layer 5 and outer metal level 6
Tape splicing 7, the inner metal layer 5, outer metal level 6 and connect band 7 enclose to form threading passage 8, are set in the threading passage 8
There is the second conductor, asbestos cord 9 is filled between second conductor and threading passage 8.
The first wire, the wrapped ceramic fireproof on the outside of the first wire that first conductor includes middle part are compound
Belt 10 and the wrapped mica belt 11 in the outside of ceramic fireproof composite band 10；The section of first wire is circle
Shape, it is enclosed for fan-shaped copper cash 14 by some sections and formed.Preferably, the quantity of the copper cash 14 is eight.
Petroleum jelly can play a part of moistureproof and insulation, prevent the cable core moisture absorption from causing decreasing insulating.Steel wire fills armour
Layer has excellent heat dispersion and mechanical performance.Alkali-free glass fibre band has temperature resistant grade height, good insulation preformance, anticorrosive
The advantages that ability is strong.
The section of first wire is circle, and it is enclosed for fan-shaped copper cash 14 by some sections and formed.Preferably,
The quantity of the copper cash 14 is 8, and the section of each copper cash 14 is 1/8th circles.By the selection to copper section, avoid
The problem of resistivity that strands are brought is high.
Second conductor includes second wire 12 at middle part, is arranged on the polyvinyl chloride insulation layer in the outside of the second wire 12
13.Second wire 12 is that copper wire and iron wire are twisted.
The inner restrictive coating 1 forms for PVC insulating tapes are wrapped.The external sheath layer 4 for low smoke, zero halogen polyethylene extrudes and
