Specific embodiment
Embodiment
As shown in Figure 1 and Figure 2, the anti-oxidant special cable of high-low temperature resistant provided in this embodiment includes multiple being distributed in a ring
Core 1 and be successively coated on the first protective layer 3, the second protective layer 4, fireprotection layer 5 and the sheath 6 in 1 outside of multiple cores, it is described
Core 1 includes copper conductor 11 and the flame retardant coating 12 and insulating layer 13 for being successively coated on each 11 outside of copper conductor, the copper conductor
11 are constituted by more tin plating copper wire of more root surfaces are twisted, and the copper conductor 11 made of more root surfaces tin plating copper wire is led with height
The load capacity of cable can be improved in the advantages of electric rate, and the flame retardant coating 12 is made of two-sided mica tape, the two-sided synthetic mica tape
