Abstract
The utility model relates to the technical field of power transmission equipment, and especially relates to a novel flame-retardant cable. The cable comprises an inner sheath, grooves, inner conductors, an optical fiber, a nylon sheath, a silica gel layer, and a waterproof layer. The grooves are disposed on the inner sheath. The grooves are embedded with the inner conductors. The center of the inner sheath is provided with the optical fiber. The silica gel layer is disposed between the inner sheath and the nylon sheath. The waterproof layer is covered outside the nylon sheath. Bottoms of the grooves are in an arc shape. The inner sheath is filled with oxygen separating flame-retardant materials. The novel flame-retardant cable is simple, compact, and reasonable in structure, carrying capacity of the cable is improved, and the cable has good anti-interference performance, good insulating properties, and good anti-corona performance. Flame retardant performance of the cable is improved, heat-conducting performance is good, service life of the cable is prolonged, working reliability of the cable is greatly improved, and the cable is easy to popularize.
Description
Technical field
The utility model relates to a kind of technical field of power transmitting device, especially a kind of Novel flame-retardant cable.
