Multi-purpose optical fiber composite overhead phase conductor

Abstract

The invention provides a multi-purpose optical fiber composite overhead phase conductor. The multi-purpose optical fiber composite overhead phase conductor has the function of autonomous induction of changes in an external environment, and thus the work state can be adjusted and the service life can be prolonged. The multi-purpose optical fiber composite overhead phase conductor comprises a central light unit, wherein the central light unit is positioned in a central cavity formed by being wrapped by aluminum-clad steel wires; the aluminum-clad steel wires are hinged to the outer layer of the central light unit; one or more layers of aluminum wires for electrical purposes are hinged to the outer layers of the aluminum-clad steel wires; the central light unit comprises a stainless steel pipe, optical fibers and fiber grease; the optical fibers comprises one or more induction optical fibers and one or more common communication optical fibers; the induction optical fibers and the common communication optical fibers are distributed in the inner cavity of the stainless steel pipe; intervals in the inner cavity of the stainless steel pipe are filled with the fiber grease; the fiber grease is utilized for protecting the optical fibers and preventing water.

Description

technical field [0001] The invention relates to the technical field of cable structures, in particular to a multi-purpose optical fiber composite overhead phase line. Background technique [0002] The existing optical fiber composite overhead phase line products are mostly made of stainless steel optical fiber unit and aluminum-clad steel monofilament twisted and then outer layer twisted aluminum wire. The optical fiber is located in the middle of the stainless steel tube, which has a series of excellent performances such as good transmission and communication, and strong anti-interference. At the same time, the optical fiber design has a certain excess length, which ensures that the service life of the optical cable will not be affected by external force changes during use. The excess length of this part of the optical fiber usually needs to reach about 5‰. Usually, the difference in excess length of all optical fibers in an optical unit is controlled within 1‰ during prod...

Problems solved by technology

[0003] The existing optical fiber composite overhead phase wire cannot self-adjust according to the external environment changes of the phase wire, so that the optical fiber composite overhead phase wire is in a working state for a long time, which makes the service life of the optical fiber composite overhead phase wire short, and subsequent replacement and maintenance trouble
