Embodiment Construction

[0036] Below in conjunction with example the present invention will be further described:

[0037] exist figure 1 Among them, a low-smoke, flame-retardant, tensile-resistant elevator monitoring special cable, including a copper core conductor 10, the outer layer of the copper core conductor 10 is composed of a polyethylene insulating layer 20, an aluminum foil Mylar layer 30, a tinned copper wire braiding layer 40, and a fiber wire The braided mesh layer 50 and the PVC coating layer 60 are covered sequentially.

[0038] In this embodiment, two reinforced tensile steel wire ropes 70 are arranged symmetrically between the fiber wire braided mesh layer 50 and the PVC coating layer 60 .

[0039] Take 100 parts of polyvinyl chloride resin as base material, add 16 parts of graphite powder, 0.5 part of oleic acid amide, 40 parts of trioctyl trimellitate, 1 part of barium stearate, NdCl 3 0.5 parts, 0.5 parts of zinc stearate, 0.5 parts of triphenyl phosphate, 0.5 parts of dipentaer...

Abstract

The invention belongs to the technical fields of cables, in particular to a low-smoke flame-retardant pull tension cable special for elevator monitoring. The cable comprises a copper core conductor (10) and is characterized in that: an outer layer of the copper core conductor (10) is coated by a polythene insulating layer (20), an aluminum foil nylar layer (30), a tinned copper wire braided layer (40), a fiber filament weaving net layer (50) and a PVC coated layer (60) in turn. The cable has the advantages of high tensile strength, high flexibility, good flame retardant and smoke suppression performance, reasonable cost performance, and suitability for video transmission and signal control for an elevator monitoring system.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a low-smoke, flame-retardant, tension-resistant elevator monitoring special cable. Background technique [0002] With the development of society, the application of elevators is becoming more and more extensive. In 1999, GB50096-1999 "Code for Residential Design" stipulated that the residential buildings with 7 floors or above or the height of the entrance floor of the households from the outdoor design ground must be more than 16m. Elevators must be installed. . With the emergence of modern intelligent high-rise buildings, elevators in hotels, restaurants, office buildings, apartments, etc. need TV systems to monitor the elevator's work and activities, so as to keep abreast of the elevator's operation; when the elevator fails, it can also make rescue The personnel keep abreast of the situation of the people trapped in the elevator, so as to formulate a rescue plan. [0003] The...
