Problems solved by technology

[0002] At present, the optical fiber composite overhead phase line of the existing transmission lines generally uses a single steel wire or steel strand as the central reinforcement, and the twisted layer is made by twisting the optical fiber unit of the stainless steel tube as the sleeve and the round aluminum metal wire. As a result, this kind of optical fiber composite overhead phase line has large sag, large cross-sectional area, large DC resistance, low carrying capacity, large wind pressure load, easy to freeze on the surface, high probability of galloping, general self-damping performance and low corrosion resistance. , resulting in easy damage to the phase wire

Embodiment Construction

[0012] The present invention will be further described in detail according to the examples below.

[0013] refer to figure 1 , the present invention a kind of manufacturing method of low sag, soft aluminum type line optical fiber composite overhead phase line, comprising:

[0014] 1) First set the optical fiber 3 in the stainless steel casing 2;

[0015] 2) The outer surface of the stainless steel sleeve 2 is extruded with a fan-shaped aluminum cladding layer 5 to make an optical fiber unit 4;

[0016] 3) Then simultaneously twist the fan-shaped annealed aluminum wire 6 and the optical fiber unit 4 outside the carbon fiber composite core 1;

[0017] 4) Finally twist at least one layer of fan-shaped annealed aluminum wire 6 on the outermost layer.

[0018] Such as figure 1 As shown, a low sag, soft aluminum type fiber composite overhead phase line is composed of a carbon fiber composite core 1, a conductor and an optical fiber unit 4, and a conductor and an ...

Abstract

The invention discloses a manufacturing method for a low-sag soft-aluminum-wire optical fiber composite overhead phase line. The method comprises the following steps that 1) optical fibers are arranged in a stainless steel casing pipe; 2) a fan-shaped aluminum cladding layer is extruded on the outer surface of the stainless steel casing pipe to form an optical fiber unit; 3) fan-shaped soft aluminum wires and the optical fiber unit are simultaneously intertwisted outside a carbon fiber composite core; 4) and at least one layer of fan-shaped soft aluminum wires are intertwisted on an outermost layer.

Description

technical field [0001] The invention relates to a method for manufacturing overhead wires of power transmission lines, in particular to a method for manufacturing overhead phase wires with low sag and soft aluminum type wires and fiber optic composites. Background technique [0002] At present, the optical fiber composite overhead phase line of the existing transmission lines generally uses a single steel wire or steel strand as the central reinforcement, and the twisted layer is made by twisting the optical fiber unit of the stainless steel tube as the sleeve and the round aluminum metal wire. As a result, this kind of optical fiber composite overhead phase line has large sag, large cross-sectional area, large DC resistance, low carrying capacity, large wind pressure load, easy to freeze on the surface, high probability of galloping, general self-damping performance and low corrosion resistance. , resulting in easy damage to the phase line.
