Abstract
The invention discloses a cable for an oil drilling platform. The cable comprises a cable core. The cable core comprises a V-shaped rubber framework. A fan-shaped main conductor is arranged above the V-shaped rubber framework. A fluoroplastic insulating layer is arranged on the main conductor in an extruding mode. Two power cable core bodies are arranged on the lower portion of the V-shaped rubber framework. Each power cable core body comprises two power conductors, wherein a polyolefin insulating layer is wrapped on each power conductor. Every two power conductors are twisted and then wrapped in a mica layer. The cable core and three hollow fluoroplastic hoses are twisted and then are sequentially wrapped in a wrapping layer, a glass fiber flame-retardant layer and an outer sheath. By the adoption of the V-shaped rubber framework, the firmness of the cable is guaranteed, and the main conductor can be distinguished from the other conductors; the hollow fluoroplastic hoses are used as filling materials, so that the weight of the cable is reduced, the outer diameter of the cable is not increased, and the cable is convenient to use and practical.
