Problems solved by technology

[0003] In recent years, cable companies have generally realized the shortcomings of overhead insulated cables, and are constantly exploring and improving them. For example, Chinese patent 200820178715.6 discloses a single or multi-strand steel wire as the central reinforcing core, and then twists aluminum or aluminum wires outside it. Alloy conductors still do not have the required tensile strength; and the structure of copper-clad steel and aluminum-clad steel strands used in Chinese patent 200920208822.3, the structure bears the tensile force or steel wire, compared with the aforementioned, there is no substantial difference. Improvement; in terms of photoelectric composi...

Embodiment 1

[0019] Example 1: Such as figure 1 As shown, a reinforced optical fiber composite high temperature resistant overhead insulated cable, from the inside to the outside, includes a solid carbon fiber composite reinforced core 2, five electrical soft aluminum monofilaments 1 and a stainless steel tube optical unit 3 in turn from the inside to the outside. The adjacent outer layer and the outer side of the formed single-tube layer-stranded type are the high temperature resistant insulating material layer 4.

[0020] The high-temperature resistant insulating material is silicon rubber or fluoroplastics; other materials can be used instead of electrical soft aluminum monofilaments as conductors.

[0021] Such as image 3 As shown, the stainless steel tube light unit is composed of a number of optical fibers 8 placed in a stainless steel tube 5. The stainless steel tube 5 adopts a loose tube structure, the space of the stainless steel tube 5 is filled with a special filling paste 7 for lig...

Embodiment 2

[0022] Example 2: Such as figure 2 As shown, a reinforced optical fiber composite high temperature resistant overhead insulated cable, from the inside to the outside, includes a composite reinforced core made of seven fine carbon fibers stranded in the center 2 and a number of 63% IACS electrical soft aluminum monofilaments 1 The adjacent outer layer of the multi-tube stranded type formed by twisting with two stainless steel tube light units 3 has a silicone rubber layer or a fluoroplastic layer 4 on the outside.

[0023] Manufacturing method: twist the fine carbon fiber composite core to make a composite reinforced core and place it in the center of the concentric stranded conductor, and then continue to twist the electrical soft aluminum monofilament on it in the same way, and the adjacent layer of electrical soft aluminum monofilament The twisting direction should be opposite, and then twist the prefabricated stainless steel tube light unit with the outermost electrical soft a...

Embodiment 3

[0025] Embodiment 3: A reinforced fiber optic composite high temperature resistant overhead insulated cable with a rated voltage of 10kV, and the shielding layer of semiconducting conductor should be extruded.

[0026] Other structures are the same as in embodiment 1 or embodiment 2.

Abstract

The invention relates to a reinforced high-temperature resistant optical fiber composite overhead insulating cable, which comprises an electric flexible aluminum twisted wire serving as a conductor; a stainless steel tube optical unit and a carbon fiber composite reinforced core are arranged in the electric flexible aluminum twisted wire; and the outer side of the electric flexible aluminum twisted wire is coated with a high-temperature resistant insulating material. By the cable, a running temperature can be raised to above 180 DEG C and the tensile capability can be improved to 2,400MPa for a long time; and the cable has functions of communication, warning, information feedback and the like.

Description

Technical field [0001] The present invention belongs to overhead insulated cables, and particularly relates to the transformation and construction of overhead lines of urban and rural power grids. It can be a new type of overhead insulation that can withstand high-strength tension of 2400Mpa and allow long-term operating temperatures of over 180°C, and has communication and monitoring functions. cable. Background technique [0002] As we all know, conventional overhead insulated cables usually use copper stranded wire, aluminum stranded wire, aluminum alloy stranded wire, steel core aluminum stranded wire, etc. as the conductor, and the conductor is extruded to form an insulating layer. The tensile strength of the steel core aluminum stranded wire conductor The strength performance index is the best, which can achieve 1240Mpa-1410Mpa, but the air corridors that can be used in rural, mountainous and forest areas are gradually reduced, the distance between the poles and towers incr...
