Abstract

The invention discloses a reinforced anti-bending flat low-voltage insulated elevator cable. The reinforced anti-bending flat low-voltage insulated elevator cable includes a flat outer sheath; three square holes and two circular holes are formed in the outer sheath; insulated wire cores of the same number are arranged in each square hole; a tensile component is arranged in each circular hole; a reinforcing component is arranged at the center of the plurality of control wire cores in each square hole; a plurality of semicircular grooves are formed on the periphery of the outer sheath; and the semicircular grooves are arranged between every two sets of adjacent cable cores. The reinforced anti-bending flat low-voltage insulated elevator cable of the invention has the advantages of simple structure, high mechanical strength and excellent anti-bending resistance. With the reinforced anti-bending flat low-voltage insulated elevator cable of the invention adopted, the problem of high possibility of core fracture of the elevator cable under a frequent bending environment can be effectively solved, and the service life of the elevator cable can be prolonged.

Description

technical field [0001] The invention relates to the field of elevator cables, in particular to a reinforced bending-resistant flat low-voltage insulated elevator cable. Background technique [0002] The elevator cable is an important supporting part of the elevator. It needs to move up and down with the elevator. During this process, the elevator cable must not only bear its own weight, but also bear the stress caused by frequent U-shaped bending. With more and more high-rise buildings, elevators are running faster and faster. Traditional elevator cables can no longer meet the operating requirements of elevators. Problems such as core breakage and outer sheath cracking are prone to occur. Outage failure requires the entire root to be replaced, which is quite troublesome to repair. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reinforced bending-resistant flat low-voltage insulated elevator cable with simple ...
