Aluminum alloy shaped wire photoelectric composite cable

Abstract

The invention discloses an aluminum alloy shaped wire photoelectric composite cable which comprises a core wire. The core wire is formed by stranding a plurality of galvanized stranded steel wires, a plurality of trapezoid aluminum alloy single wires and a trapezoid optical unit are concentrically stranded outside the core wire, and a plurality of fan-shaped aluminum alloy single wires are concentrically stranded outside the trapezoid aluminum alloy single wires and the trapezoid optical unit. The defects that common round wire aluminum conductor stranded wires are large in loss and low in tensile strength, and cannot be laid in an overhead mode in long distance in actual use are overcome. Shaped wires are tightly stranded, and the maximum electric conduction sectional area is made to exist in limited space of the equal outer diameters of wires. When wire transmission capacity is increased to 180%-200% of a conventional wire, a wire sag increment is still within the range allowed by the conventional wire, and the aims of power transmission energy saving and capacity improving are achieved.

Description

technical field [0001] The invention relates to an aluminum alloy type wire photoelectric composite cable. Background technique [0002] With the rapid development of my country's transmission lines, the transmission capacity of newly built lines is increasing, and the performance requirements for the conductors used in transmission lines are getting higher and higher. In many places where lines are laid, it is often necessary to transmit power and optical signals at the same time. Optical cables for optical signal transmission and cables for power transmission are usually laid separately, which not only brings difficulties to construction, but also increases usage and construction costs. [0003] Contents of the invention [0004] The invention provides an aluminum alloy type wire photoelectric composite cable, which has a simple structure, overcomes the deficiencies in the operation of other conventional wires, has low loss, high tensile strength, and can be laid overhe...

In many places where lines are laid, it is often necessary to transmit power and optical signals at the same time. The optical cables used for optical signal transmission and the cables used for power transmission are usually laid separately, which not only brings difficulties to the construction, but also increases the use and construction costs.
