Abstract
The utility model discloses an oil-resistant flame-retardant flexible power cable. The cable comprises three conductors, wherein each conductor is wrapped in an insulating layer to form an insulating conductor core, and the three conductor cores are arranged in a close-triangular shape and wrapped in a wrapping layer to form a cable core; three high temperature resistant fillings whose cross section is fan-shaped are arranged between the insulating layers and the wrapping layer of the cable core, wherein a high temperature resistant fiber rope is arranged in the center of each high temperature resistant filling, a fireproof layer formed by wrapping high temperature resistant glass fibers is arranged outside each high temperature resistant filling, and the thickness of the fireproof layer is not less than 0.8mm; and a flame-retardant butyronitrile oversheath layer is extruded from the cable core. The oil-resistant flame-retardant flexible power cable is reasonable in structure and design and possesses good tensile performance, wherein high temperature resistant fillings are arranged in the cable core and wrapped in the fireproof layers, so that the structural compactness of the cable is improved, and the cable can prevent flames from burning inwards, thereby ensuring smooth power and communication in certain time and bringing precious rescue time for rescuers.
