Light bend-resistant cable

Abstract

The invention discloses a light bend-resistant cable which comprises an outer sheath, a strengthening protective layer, a conductor and a rubber pipe, wherein the rubber pipe is a hollow pipe made of rubber materials; a nylon strengthening net sleeve is pre-embedded into the wall of the rubber pipe; conductors are respectively arranged at the periphery of the rubber pipe; the strengthening protective layer wraps the outer sides of the conductors, and is an overlapped wrapping non-woven fabric tape; and the outer sheath is arranged outside the strengthening protective layer. By adopting the mode, the light bend-resistant cable disclosed by the invention has the advantages of good bend-resistant property, light weight and high tensile strength by substituting the overlapped wrapping non-woven fabric tape for a metal tape on the strengthening protective layer, and can be used for protecting the conductors from being damaged when the conductors are extruded and impacted through reasonable deformation by having good elastic deformation capacity, thus achieving easiness in bending, good durability and flexibility and convenience in construction.

Description

technical field [0001] The invention relates to the field of cables, in particular to a lightweight and bending-resistant cable. Background technique [0002] The wire and cable industry in my country is the second largest industry after the automobile industry. The total output value of wire and cable has surpassed that of the United States, becoming the world's largest producer of wire and cable. [0003] The main material of the cable is a metal conductor and sheath. The conductor itself has a large weight, and a metal belt is arranged around the conductor. In order to improve the tensile strength of the cable, some cables have added a steel wire reinforcement core, and the weight of the cable is also increased. The rise brings difficulty to the laying of cables, and requires higher ground support settings, and is not easy to bend, which increases the difficulty of construction, and has no deformation buffering ability, and is prone to breakage during extrusion.
