In this embodiment, if not specifically described, the members may be connected or fixed by bolts, pins, or the like, which are commonly used in the prior art, and therefore, the details thereof will not be described in this embodiment.
An anti-aging cable is shown in fig. 1, and comprises a plurality of stranded wire cores 1, a filling layer 2 wrapping the periphery of the wire cores 1, an insulating layer 3 wrapping the periphery of the filling layer 2, an anti-aging coating layer 4 wrapping the periphery of the insulating layer 3, and a nylon woven fabric protective layer 5 wrapping the periphery of the anti-aging coating layer 4, wherein the thickness of the nylon woven fabric protective layer 5 is twice that of the insulating layer 3. The nylon braid protective layer 5 effectively protects the anti-aging coating layer 4, and avoids the condition that the insulating layer 3 is directly exposed outside to cause damage, thereby improving the protective capability of the cable.
The wire core 1 comprises a copper conductor 11, an insulating sleeve 12 wrapping the periphery of the copper conductor 11, and the copper conductor 11 adopts two types of stranded conductors. The two kinds of conductors are compressed stranded conductors, the sections of the two kinds of conductors are round, fan-shaped, tile-shaped and the like, the compression coefficient (or filling coefficient) of the two kinds of conductors can reach more than 0.9, namely, the section of a gap is smaller than 10%, the twisted wire core is compressed, the structural stability of the conductors is improved, the outer diameter of the conductors is reduced, and insulation and sheath materials can be reduced, so that the weight and the production cost of a cable are reduced, and the longitudinal water blocking of the conductors is realized.

The low smoke zero halogen flame retardant ceramic thermoplastic elastomer material with the temperature of 125 ℃ can meet the performance under the flame or flameless condition with the temperature of 650 ℃ and above. Along with the temperature rise, the ceramic-shaped hard complete shell is quickly sintered, the longer the burning time is, the higher the temperature is, the harder the shell is, the better the protection effect is played on the circuit by the hard shell after burning, and the smoothness of the circuit under the condition of fire is ensured.
The anti-aging coating layer 4 is a chlorosulfonated polyethylene coating. The coating can effectively isolate ozone and ultraviolet rays, thereby effectively slowing down the aging speed of the insulating layer 3.
