[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By arranging an oil-resistant layer on the outside of the outer sheath, the oil resistance of the control cable can be improved, and by arranging an anti-aging layer between the outer sheath and the inner sheath, the anti-aging performance of the control cable can be improved;
