Zusammenfassung: | The invention relates to a cable, and especially relates to an elevator cable. The elevator cable comprises multiple conductors and an insulator coating the conductors. The insulator is a carbon fiber insulator. Multiple accommodating cavities used for accommodating the conductors are formed in the insulator, the accommodating cavities are independent cavities which are separated from one another and are not intercommunicated, the cross section shape of the cavity body of each accommodating cavity is the same with the cross section shape of the corresponding conductor, and the inner surface of each accommodating cavity closely fits the outer surface of the corresponding conductor. Compared with the prior art, as the carbon fiber material has higher strength and better flexibility than the traditional PVC material, the insulator is effectively prevented from wearing, cracking and aging when the cable is bent, the service life of the whole cable is prolonged safely and effectively, and insulating layers coating |
