Embodiment Construction

[0015] The present invention will be further described in detail according to the examples below.

[0016] Such as figure 1 As shown, a compact special-shaped optical fiber composite overhead phase line includes a core, an optical fiber unit 4 composed of an optical fiber 3 and a stainless steel sleeve 2 surrounding the outer surface of the optical fiber, a round aluminum-clad steel wire 1 and a fan-shaped hard The aluminum wire 5 is surrounded by a first cladding layer composed of an optical fiber unit 4 and a plurality of round aluminum-clad steel wires 1, and a multi-strand fan-shaped duralumin is surrounded on the outside of the first cladding layer. The second cladding layer composed of wire 5. Each strand of the phase line is in surface contact with each other, and the wire core, the first covering layer and the second covering layer are arranged concentrically.

[0017] Compared with the ordinary optical fiber composite overhead phase wire, under the condition ...

Abstract

The invention discloses a compression specially-shaped optical fiber compound aerial phase line. The compression specially-shaped optical fiber compound aerial phase line comprises a line core, and further comprises optical fiber units, round aluminum-clad steel wires and fan-shaped hard-drawn aluminum wires, wherein each optical fiber unit is composed of optical fibers and a stainless steel sleeve arranged on the outer surfaces of the optical fibers in a surrounding mode, a first cladding layer and a second cladding layer are arranged on the outer side of the line core in a surrounding mode, the first cladding layer is composed of the optical fiber units and the round aluminum-clad steel wires, and the second cladding layer is arranged on the outer side of the first cladding layer in a surrounding mode and is composed of the fan-shaped hard-drawn aluminum wires.

Description

technical field [0001] The invention relates to an overhead wire of a power transmission line, in particular to a composite overhead phase wire of compressed special-shaped optical fiber. [0002] Background technique [0003] At present, the optical fiber composite overhead phase wire of existing transmission lines is generally made by twisting round aluminum wires on the outer layer of the core. This kind of optical fiber composite overhead phase wire has a large cross-sectional area, large DC resistance, low carrying capacity, and large wind pressure load. , the surface is easy to freeze, the probability of galloping is high, and the self-damping performance is average, which leads to easy damage to the phase line. Contents of the invention [0004] The invention provides a compressed special-shaped optical fiber composite overhead phase line with small direct current resistance, high carrying capacity, small wind pressure load, no icing on the surface, low probability...
