PVC insulated PVC sheathed flat shielded reinforced core elevator cable

Abstract

The invention relates to a flat shielding elevator cable with a polyvinyl chloride insulation jacket and a reinforced core. The cable comprises the flat polyvinyl chloride insulation jacket. A plurality of groups of first elevator traveling cable assemblies and second elevator traveling cable assemblies are arranged in the flat polyvinyl chloride insulation jacket. The first elevator traveling cable assemblies are arranged near two ends of the insulation jacket. The second elevator traveling cable assemblies are arranged near the middle of the insulation jacket. Two groups of stranded reinforced steel wire bundles are arranged near the two ends of the second elevator traveling assemblies. The flat elevator cable is applied to the inside of an elevator to be used as a traveling hanging cable, and applicable rated voltage is under 500V. During normal use, the highest temperature of a conductor is 70 DEG C, and the conductor is suitable for the environment between -15 DEG C and 40 DEG C. The free hanging length of the cable should not exceed 80 meters, and moving speed of the cable should not exceed 4 meter / second.

Description

technical field [0001] The invention belongs to the technical field of cable design and manufacture, and more particularly relates to a PVC insulated PVC sheathed flat shielded reinforced core elevator cable. Background technique [0002] With the continuous and rapid growth of my country's economy, it has provided a huge market prospect for the development of the cable industry. The strong temptation of the Chinese market has made the world focus on the Chinese market. In the short decades of reform and opening up, China has The huge production capacity formed by the cable manufacturing industry has impressed the world. With the continuous expansion of the scale of electric power, communication, rail transit, automobile and shipbuilding industries, the demand for wires and cables is also growing rapidly. It is foreseeable that the wire and cable industry will have huge development potential in the future. At present, the wire and cable industry is the second largest industr...

Problems solved by technology

The elevator is an indispensable means of transportation in high-rise buildings. It needs to move up and down frequently, and the cable that provides the working power for the elevator must also move up and down with it. With the development of technology and the needs of people's work and life, the elevator Some activities such as communication and monitoring are also required in the interior. For this reason, the relevant signal lines must be suspended next to the elevator, and the elevator is repeatedly lifted and lowered. service life, and because the various lines are too complicated, and these lines are relatively poor in tensile properties, after a long period of regular lifting movement, there may be breakage, damage, resulting in power failure or other related problems.
