Novel corrosion-resistance flexible fireproof photoelectric composite cable

Abstract

The invention relates to a novel corrosion-resistant flexible fireproof photoelectric composite cable, comprising 2 to 5 insulated wire cores and an optical fiber core twisted into a composite cable core; the insulated wire core includes a conductor and an insulating layer wrapped outside the conductor; the The optical fiber core includes the optical fiber from the inside to the outside, and the optical fiber metal protective tube is continuously welded outside the optical fiber. The metal protective tube is filled with lubricating petroleum jelly, and the metal protective tube is extruded with a high-density polyethylene optical fiber protective layer. The galvanized steel wire forms the optical fiber armor layer, and the optical fiber armor layer is extruded with a high-density polyethylene optical fiber outer sheath. The invention can be used for the transmission and distribution of electric energy, can effectively solve the problem of power consumption of equipment in network construction, and avoid repeated deployment of power supply lines. In addition, it has small outer diameter, light weight, small footprint, and is easy to purchase and construct. Low cost, convenient construction and other advantages.

Description

technical field [0001] The invention relates to electric wires and cables, in particular to a novel corrosion-resistant flexible fireproof photoelectric composite cable. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, the power supply of fire-fighting equipment closely related to people's production, the connection of equipment in densely populated buildings, the power supply and information transmission of important military industry, national defense, aviation, satellite base equipment, There are more and more connecting wires between devices in flammable and explosive places. In areas with limited wiring space, the traditional separate routing of cables and optical cables has been eliminated by most users, and replaced by a new type of photoelectric composite cable that requires fire protection and flexibility. The new type of photoelectric composite cable has a small outer diameter,...
