Embodiment 1

[0022] Such as figure 1 As shown, the copper core TPE insulated sheath wind power cable (single core) is conductor 1 from the inside to the outside, and the conductor wrapping 6 wrapped on the surface of the conductor is wrapped on the conductor wrapping layer. The TPE insulation 2 and the TPE sheath 5 covering the insulation.

[0023] The production process of the copper core TPE insulated sheathed wind power cable with severe cold resistance and twist resistance (single core) includes the following steps in sequence: during production, the strands are twisted by a stranding machine, and then twisted into a conductor by a twisting machine 1. At the same time, use a wrapping machine to wrap the conductor on the surface of the conductor 2, use a plastic extruder to extrude the TPE insulation 3 on the conductor 1, and finally extrude the TPE sheath 4 with the extruder.

Embodiment 2

[0025] Such as figure 2 As shown, the copper core TPE insulated sheathed wind power cable (multi-core) with cold resistance and twist resistance is conductor 1 from the inside to the outside, TPE insulation 2 extruded on the surface of the conductor, and PP rope filled in the gap of the TPE insulator Filling 3, cabled wrapping 4 wrapped with TPE insulator and filled, and TPE sheath 5 wrapped on its surface.

[0026] The production process of copper core TPE insulated sheathed cold-resistant and twist-resistant power cable (multi-core) for wind power generation: During production, the strands are twisted with a wire-bunching machine, and then the conductor 1 is twisted with a stranding machine, and then plastic The extruder extrudes TPE insulation 2 on the conductor 1, then uses the cable forming machine to simultaneously fill PP rope 3 and cable wrapping 4, and finally extrudes the TPE sheath 5 with the extruder.

Abstract

The invention discloses a lower temperature-resistant and distortion-resistant power cable with a copper conductor TPE insulated sheath for wind power generation, which comprises at least one conductor, wherein each conductor is externally provided with a TPE insulated layer; the outermost layer of the cable is a TPE sheath; when the number of the conductors is one, a layer of conductor lapping is arranged between the outside of the conductor and the TPE insulated layer; and when the number of the conductors is at least two, the outside of the TPE insulated layer covering the conductors is provided with a PP rope filling; and the TPE sheath is internally provided with a layer of cabling lapping to cover the PP rope filling. Detected by national authorized detection departments, the cable fully meets technical requirements of wind power cables, improves the characteristics of lower temperature resistance and distortion resistance of the wind power cables, replaces the conventional rubber insulated rubber sheath, realizes localization, and breaks through a situation of dependence on import. The TPE is a recyclable 'green material', is easy to degrade and has environmental protection and obvious economic benefit.

Description

technical field [0001] The invention relates to a power cable product, in particular to a copper core TPE insulating sheath wind power generation resistant to severe cold and twist resistant power cable. Background technique [0002] my country began to develop green and clean energy - wind power in the 1990s, but so far, there are no relevant national standards and industry standards for special cables for wind turbines in my country, and all cables are imported, such as Germany, the Netherlands and other advanced countries for wind power applications , expensive, and controlled by others. [0003] Europe is the birthplace of wind power generation. Foreign traditional low-temperature flexible cables for wind power generally use ordinary rubber insulation and sheaths. All products adopt European standards or German standards. The operating temperature is -25 to 90 ° C. 3000 times of front and back 1080 ℃ low temperature anti-torsion test. [0004] The environment in our cou...
