The utility model discloses a three-core tensile power cable for wind power generation, which comprises three alloy conductors, and the three alloy conductors are wrapped with silicon rubber insulating layers to form insulated wire cores, and the insulated wire cores and elastic wire cores are twisted into bundles with each other. Three elastic tensile core groups are formed. The elastic wire core is formed by extruding steel wire in the elastic layer. The three tensile core groups are respectively covered with wrapping layers and twisted into bundles to form the cable core. The outside is covered with a polyester tape wrapping layer and an outer sheath layer in sequence. The utility model has a novel structural design. The elastic core group is composed of an insulating core and an elastic core, which greatly improves the tensile performance of the cable. At the same time, the insulating layer uses tensile and tearing silicone rubber as the insulating material, and the outer sheath The layer is made of polyether thermoplastic polyurethane compound material, which makes the cable have excellent cold resistance, excellent electrical insulation performance, excellent oil resistance performance, and excellent ultraviolet resistance and weather aging resistance.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of used for wind power generation three core tension power cables.
Background technology:
The energy is that the mankind depend on for existence and the material base of social development, has a lot of other valuable energy to remain the mankind on the earth and goes development and utilization, such as wind energy, solar energy, geothermal energy, tidal energy etc.
Along with the development of science and technology, wind power generation is paid attention to and is developed, and according to the data demonstration of world energy sources committee issue, wind energy resources in the world has 9,600,000,000 kW, and the energy that it can provide is 15 times of global annual total energy consumption.Wind Energy In China aboundresources, wind energy gross reserves approximately have 43.5 hundred million kW, but wherein the land wind energy content of development and utilization has 300,000,000 kW, adds the territory, coastal waters, and China's wind energy content has more than 1,000,000,000 kW, and development potentiality is huge.
Often there is disconnected core phenomenon in original power cable that is applicable to used for wind power generation in the laying installation process, so that the electric power signal transmission is interrupted, bring huge economic loss, therefore needs wind electric power generation cable reasonable in design.
The utility model content:
In order to solve the problems of the technologies described above, the purpose of this utility model provides a kind of used for wind power generation three core tension power cables, and structural design is novel, and the tension that can improve significantly cable rises performance, guarantee not to be prone to disconnected core in the mounting and installation process and in using, increase the service life.
