Intelligent temperature-measuring type optical fiber composite fireproof medium-voltage hoisting cable and preparation method thereof

Abstract

The invention discloses an intelligent temperature-measuring type optical fiber composite fireproof medium-voltage hoisting cable and preparation method thereof. The cable comprises a cable core formed by stranding three insulated wires; filler strip with the section in arc sector is filled in the clearance of the cable core; a high-strength halogen-free low-smoke polyolefin ribbon is bound out ofthe cable core and tightened; a dual0layer improved glass fiber tape cooling layer with thickness of 0.6mm is lapped out of the high-strength halogen-free low-smoke polyolefin ribbon, and a halogen-free low-smoke polyolefin oxygen barrier is extruded on the same; a ceramic polyolefin outer coating is extruded on the halogen-free low-smoke polyolefin oxygen barrier, and the nanometer radiation heat-dissipating cooling paint layer are coated on the same. By adopting the photoelectric integration structure, the cable integrates the power transmission, the optical fiber communication transmission, the optical fiber intelligent temperature-measuring and fault early-warning and like functions into one, so that a power supply network has high self-checking function, and the intelligent control the high-rise buildings power transmission and transformation equipment, the facility state and data transmission is realized.

Description

technical field [0001] The invention relates to a medium-voltage power cable with a rated voltage of 6-35kV, in particular to a high-rise building that integrates functions such as electric power, optical fiber communication transmission, optical fiber intelligent temperature measurement, and fault warning to realize power transmission and transformation for high-rise buildings. An intelligent temperature-measuring optical fiber composite medium-voltage hoisting cable for intelligent control of equipment and facility status and data transmission and a preparation method thereof. Background technique [0002] With the rapid development of my country's social economy, more and more high-rise, super high-rise residential buildings, office buildings, commercial buildings, entertainment venues, etc. stand in the city. The emergence of a large number of high-rise buildings has brought vigor and vitality to the city's economic construction, commercial prosperity, prosperous environ...

AI Technical Summary

Problems solved by technology

[0005] At present, there is no professional manufacturer of this product in China; the traditional production technology is backward, the structural design is unreasonable, and the yield is low; in addition, the requirements for high flame retardancy, fire resistance and environmental protection of cables are getting higher and higher in recent years, causing many manufacturers Due to the existing technology, it is impossible to design and produce an intelligent temperature-measuring optical fiber composite fireproof medium-voltage hoisting cable that meets the technical requirements

And the production process has the following problems: 1, the processing capacity is large, and the production cost is high

2. It is not conducive to laying and management, and the risk factor is large

3. Difficult assembly of finished products and long production cycle

4. The structure is unreasonable and the laying area is large
