Abstract
The invention relates to the technical field of cable structures, in particular to an elevator communication network data cable. The elevator communication network data cable comprises an outer sheath, and the outer sheath is internally provided with a data network cable, a positive power line, a negative power line and two reinforcing lines; the data network cable comprises a conductor layer, a non-woven fabric belting layer and a tinned copper woven mesh which are sequentially arranged from inside to outside, the conductor layer comprises four pairs of insulating core wires and a plurality of tensile cotton threads, the plurality of tensile cotton threads and the four pairs of insulating core wires are stranded with each other, each pair of insulating core wires comprises a shielding layer and two copper conductor core wires which are arranged in the shielding layer and stranded with each other, and each copper conductor core wire comprises a first insulating layer and a plurality ofoxygen-free copper wires which are arranged in the first insulating layer and stranded with each other. The elevator communication network data cable is novel in structure, ingenious in design and high in anti-interference capability; and moreover, the tensile property of the insulating core wire is improved, pull-apart is avoided, the reliability is high, and the structure is firm.
Description
technical field [0001] The invention relates to the technical field of cable structures, in particular to an elevator communication network data cable. Background technique [0002] With the emergence of modern intelligent high-rise buildings, the elevators of hotels, restaurants, office buildings, and apartments need various communication network systems such as audio and video systems, multimedia systems, and monitoring systems. The elevator moves up and down, and the cable is pulled and bent countless times, so it needs to have sufficient strength. However, the existing special cable for elevator monitoring has poor shielding effect, weak anti-interference ability, poor fatigue resistance and low tensile strength. Therefore, a new elevator network cable is needed. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides an elevator communication network data cable, which has novel structure, ingenious design, strong an...
