In the cable process for the engine room in the prior art, the number of conductors is small, the diameter of a single wire is large, the conductors are stranded once by adopting bundle twisting, the stranding is not untwisted, and an insulating material adopts cross-linked polyolefin. The engine compartment cable produced by the process has poor flexibility and is not easy to bend due to the thick diameter and small quantity of copper wires forming the conductor, and the minimum bending radius allowed statically is more than 5D (the outer diameter of the cable) generally, so that the cable is not easy to lay in a narrow space. Meanwhile, the cable conductor is twisted by adopting a one-time twisting mode, single copper wires forming the conductor are irregularly arranged, the roundness is poor, and after the cable is bent, the conductor is easy to deform due to the unstable structure of the conductor, so that the service life of the cable in a bent state is influenced.
Therefore, a technical solution to the above problems is urgently needed in the prior art.
