Weather-resistant flexible wind power generation cable and production process thereof

Abstract

The invention discloses a weather-resistant flexible wind power generation cable and a production process thereof. The cable comprises a conductor, an isolating layer, an insulating layer and a sheath layer which are sequentially arranged from inside to outside, the conductor is a flexible aluminum alloy molded line conductor; and the sheath layer is a weather-resistant JC284FR type sheath, and a special annealing process is adopted for the conductor during production. According to the invention, the flexibility and weather resistance of the cable are greatly improved, and the laying requirement of the open-air steel frame tower drum fixed section in a special use environment can be met.

Description

technical field

[0001] The invention relates to the technical field of cables, in particular to a weather-resistant flexible wind power generation cable and a production process thereof. Background technique

[0002] At present, with the country's vigorous promotion of clean energy construction, the wind power field is also developing rapidly. If wind power manufacturers want to maintain profitability, they are faced with the need to significantly reduce costs. A steel frame supported fan came into being. Compared with traditional fans, This kind of fan adopts steel frame support to replace the tower support, which leads to the fact that the cables fixedly laid in the original tower are now exposed to the open air without any shielding and protection, and the weather resistance of the cables is facing the test, so the fan manufacturers also Higher requirements for cable weatherability indicators. In addition, under the long-term wind blowing, the cables laid in the open air...

Examples

Embodiment 1

[0035] like figure 1 The weather-resistant flexible wind power generation cable shown includes a conductor 1, an isolation layer 2, an insulating layer 3 and a sheath layer 4 sequentially arranged from the inside to the outside; the conductor 1 is a flexible aluminum alloy profile conductor, which greatly improves the cable's durability. Flexible; the sheath layer is a weather-resistant JC284FR type sheath, which has excellent weather resistance, and an isolation layer 2 is set between the conductor 1 and the insulating layer 3 to homogenize the electric field, prevent the conductor from oxidizing, and reduce the electrical loss. The laying requirements of the fixed section of the open-air steel frame tower for its special use environment.

[0036] The conductor 1 includes a circular guide core 1-1 set in the center and a plurality of profile layers 1-2 closely surrounding the circular core 1-1 in sequence, and each profile layer 1-2 is composed of a plurality of trapezoidal s...

Embodiment 2

[0047] The structure and composition formula of this embodiment are the same as those of embodiment 1, the difference is that the annealing process is different, the annealing temperature of conductor 1 is 400°C, and the annealing time is 3h.

Embodiment 3

[0049] The structure of this embodiment is similar to that of Embodiment 1, the difference is that the formula ratio of the conductor 1 and the sheath layer 4 is different. The composition and proportion of the conductor 1 are calculated by mass percentage as follows: aluminum content 99%, silicon content 0.05%, iron content 0.55%, copper content 0.20%, magnesium content 0.03%, zinc content 0.01%, boron content 0.02%, rare earth content The content is 0.04%, and the rest are impurities.

[0050] The sheath layer 4 adopts JC284FR type sheath, and its composition and proportion are calculated in parts by mass: 45 parts of chlorinated polyethylene, 55 parts of chlorosulfonated polyethylene, 2 parts of ethylene-vinyl acetate copolymer, and 60 parts of talcum powder. 35 parts of calcium carbonate, 55 parts of magnesium hydroxide, 10 parts of carbon black, 70 parts of magnesium oxide, 4 parts of Hongdan, 20 parts of plasticizer DOS, 5 parts of paraffin oil, 2 parts of UV-resistant a...
