Problems solved by technology

[0002] In recent years, with the continuous increase of my country's infrastructure construction, the real estate industry has experienced an unprecedented blowout market, high-rise buildings continue to emerge, and the demand for elevators has increased rapidly. With the increase in elevator function requirements, signal lines, video lines, and network cables have been widely used in elevator accompanying cables. At present, most of the network cables in accompanying elevator cables use Category 5 network cables. Polyethylene sheath, the cable is relatively hard and not easy to bend, and the service life is short

Abstract

The invention relates to a traveling elevator cable. The traveling elevator cable comprises a flat cable sheath, wherein cable cores are respectively arranged at two ends in the cable sheath; a butterfly cable is arranged in the middle in the cable sheath. The traveling elevator cable is long in service life, and is unlikely to break after being used for a long time, thereby guaranteeing the transmission stability of network signals.

Description

technical field [0001] The invention relates to an accompanying elevator cable, which belongs to the technical field of cable structures. Background technique [0002] In recent years, with the continuous increase of my country's infrastructure construction, the real estate industry has experienced an unprecedented blowout market, high-rise buildings have continued to emerge, and the demand for elevators has increased rapidly. With the increase in elevator function requirements, the elevator accompanying cables, signal lines , video screen lines, and network lines have been widely used. At present, most of the network lines in the accompanying elevator cables use Category 5 network lines. The cable uses a single-strand annealed copper wire structure. After frequent bending, the conductor is prone to breakage and the signal transmission is unstable; at the same time, the ordinary circular optical cable is made of polyethylene sheath, the cable is relatively hard and difficult t...
