Special anti-aging cable for low wind speed wind-driven generator set

Abstract

The invention discloses a special anti-aging cable for a low wind speed wind-driven generator set. The cable comprises at least two conductors, wherein a wrapping mica tape refractory layer and an organosilane crosslinked polyethylene insulating layer are sequentially arranged at the periphery of each conductor; the at least two stranded conductors with the organosilane crosslinked polyethylene insulating layers form a core wire; a polyester tape wrapping layer and a copper tape internal shielding layer are sequentially arranged at the periphery of each core wire to form a unit core; at leasttwo unit cores and a filling layer are stranded into a cable core; a wrapping alkali-free glass fiber tape belting layer, a copper tape total shielding layer, an extruded ceramic silicone rubber lining layer, a zinc-plated steel tape armor layer and a flame-retardant jacket layer which are tightly adhered to one another are sequentially arranged outside the cable core. The cable is simple in structure, novel in design, stable in structure, and good in fireproof performance, has excellent heat resistance, ageing resistance, flame resistance, insulating property and electric performance, and hasexcellent social benefit and economic benefit and a wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant cables, in particular to a special cable for aging-resistant low-wind-speed wind energy generating sets. Background technique [0002] Wind power generation is currently the fastest-growing, most mature, and most promising way of generating electricity for large-scale development and commercialization among renewable energy sources. At the same time, wind power is inexhaustible, and it is a clean and renewable green Energy has been highly valued and vigorously promoted by the international community. At present, my country's large-scale energy utilization is mainly concentrated in high wind speed areas with excellent wind energy resources, while there is almost no development in low wind speed areas where wind energy resources are abundant and available. These areas account for about 68% of the country, and the main areas of resource consumption in my country are all in low wind speed are...

AI Technical Summary

Problems solved by technology

[0003] Due to the low wind speed wind power generation in my country has the characteristics of low energy density, unstable wind force, fluctuating from time to time, and unstable wind direction, as well as turbulence characteristics that cause system instability.

For the wind energy cables known as the "blood vessels" and "nerves" of wind turbines, they must not only have excellent torsion resistance, flame retardancy, oil corrosion resistance, aging resistance, high and low temperature resistance, but also have the ability to adapt to low temperature, sandstorms, and salt spray. , thunderstorm, high voltage and other special environments, but the current cables cannot meet this requirement very well, and there are many deficiencies
