Environment-friendly nano-composite high polymer control cable

Abstract

The invention discloses an environment-friendly nano-composite high polymer control cable. Multiple insulated conductor cores are intertwisted to form a cable core; a packing layer is arranged in a gap of cable cores; each insulated conductor core consists of a conductor, an inner mica wrapped refractory layer and an insulating layer from inside to outside. The insulating layer is a polyethylene montmorillonite nano-composite insulating layer; and a waterproof polyester tape, a wrapping layer, an outer mica tape refractory layer, an oxygen insulation waterproof layer, a galvanized steel strip armored layer and a restrictive coating successively are arranged outside the cable core and the packing layer. The cable has the advantages of high environmental protection performance, good ant and rat prevention performance, fire performance and radial and axial waterproof performance, and high mechanical strength; and during burning, little smoke and no harmful haloid acid substance are produced.

Description

Technical field: [0001] The invention relates to an environment-friendly nanocomposite polymer control cable. Background technique: [0002] Conventional wires and cables are quite serious sources of pollution, which will produce a lot of public hazards such as dioxins, lead, and halogens when they are manufactured, used, and disposed of. In recent years, Europe, the United States and Japan have attached great importance to the pollution related to wires and cables. Their governments have not only strictly controlled the emissions during the cable manufacturing process, but also implemented comprehensive monitoring of the disposal of scrap cables, forcing traditional cable manufacturing. Manufacturers replace traditional materials with environmentally friendly materials to manufacture environmentally friendly nanocomposite polymer cables or so-called "clean cables". [0003] At present, the cables sold on the market include low-smoke and halogen-free control cables, ant-pro...

AI Technical Summary

Problems solved by technology

[0003] At present, the cables sold on the market include low-smoke and halogen-free control cables, ant-proof or rodent-proof control cables, waterproof control cables, flame-retardant control cables, fire-resistant control cables, flame-retardant and fire-resistant control cables, etc. The main safety performance of these cables is Monotonous, unable to meet the needs of two or more safety performances; light rail subways, nuclear industry, airports, stations, offshore platforms, hospitals, office buildings and other public places with relatively concentrated personnel, as well as important areas of industrial and mining enterprises require cables to have high environmental performance and High-strength performance. At the same time, these areas are also places where termites or rats are rampant. The cables are required to have anti-ant and rodent performance. The places where people are concentrated also require that the cables can be guaranteed to run for a period of time in case of fire to ensure that people have enough time to escape. The above places There is more or less water or water vapor in the cable channel, which requires the cable to have good water resistance and high strength performance, so the cables with single safety performance used in the above places cannot guarantee safe operation
