Description

A kind of flexible Special power cable used for wind power generation

Technical field

This utility model relates to the design field of a kind of used for wind power generation flexible Special power cable being mainly used in the electric energy transmission of coastal wind energy power plant.

Background technology

The energy is that the mankind depend on for existence and the material base of social development, 20th century, the population of the earth added four times, energy resource consumption but adds 16 times, and according to the publication of the United Nations, the petroleum resources verified can only be with 44 years, natural gas 62 years, coal 230 years, the new forms of energy of Sustainable Development, have been the task of top priority, also have a lot of other valuable energy to need the mankind on the earth and go development and utilization, such as wind energy, solar energy etc..Development along with science and technology, wind power generation has been paid attention to and has been developed, THE WIND ENERGY RESOURCES IN CHINA is enriched, development potentiality is huge, for coordinating the enforcement of domestic Wind Power Project, by existing national standards produce cable can not meet coastal wind energy power plant with mainly have following some: 1. conductor tensile strength is not, and conductor is non-watertight.2. insulant is the most aging, produces a large amount of toxic gas, resistance to ambient temperature low after non-refractory, not oil resistant, the most alkaline-resisting, burning.3. packing material is the most fire-retardant, non-watertight, do not block water.4. overcoat during mounting and installation easily rupturable enter sea water, enter and become rusty on armor after sea water, etching insulative causes and punctures, and easily hardening fracture in long-time sea water immersion surface, antibiont destructive power is the strongest.5. cable entirety tensile strength and structural stability are inadequate, and cable is after laying, and with the tide is flowing and ebbing cable flexing relatively havoc cable internal structure of sea water, easily cause cable short circuit.According to above-mentioned situation it is necessary to have meet the special cable of this characteristic of coastal wind energy power plant, the requirement of engineering can be met.

Utility model content

This utility model purpose is for problem above, it is provided that a kind of tensile strength height, good waterproof performance, the used for wind power generation flexible Special power cable of raising life of product.

This utility model includes cable core, is orderly arranged outside each QXT-3 high fire-retardance twining package tape, the first water blocking tape layer, the second water blocking tape layer, poly-full tetrafluoroethene inner liner, high-carbon seizing wire braiding armor, the first nonwoven layer, the second nonwoven layer, thermoplastic elastomer sheath layer and burr type anti-skid cloth overcoat at described cable core；QXT-3 high fire-retardance gasket for packing is set between described cable core and QXT-3 high fire-retardance twining package tape；Described cable core includes split conductor core, and per share described insulated wire cores includes bundle strand conductor, is orderly arranged outside each poly-full tetrafluoroethene insulating barrier and elastic polyurethane sheath at described bundle strand conductor；Arranging multiply water blocking yarn between described bundle strand conductor and poly-full tetrafluoroethene insulating barrier, described multiply water blocking yarn is distributed across each portion of bundle strand conductor.

This utility model is simple and reasonable, has the features such as low temperature resistant, corrosion-resistant, fire-retardant, cleaning, environmental protection, and after burning, solid does not falls off, and effectively protection cable core uses in above-mentioned situation normal power-up, meets the special occasions requirement of riverine wind energy power plant.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As shown in Figure 1, this utility model includes cable core, is orderly arranged outside each QXT-3 high fire-retardance twining package tape the 1, first water blocking tape layer the 2, second water blocking tape layer 3, poly-full tetrafluoroethene inner liner 4, high-carbon seizing wire braiding armor the 5, first nonwoven layer the 6, second nonwoven layer 7, thermoplastic elastomer sheath layer 8 and burr type anti-skid cloth overcoat 9 at cable core；QXT-3 high fire-retardance gasket for packing 10 is set between cable core and QXT-3 high fire-retardance twining package tape 1；Cable core include split conductor core 11, per share insulated wire cores 11 include bundle strand conductor 12, bundle strand conductor 12 be orderly arranged outside each poly-full tetrafluoroethene insulating barrier 13 and elastic polyurethane sheath 14；Arranging multiply water blocking yarn 15 between bundle strand conductor 12 and poly-full tetrafluoroethene insulating barrier 13, multiply water blocking yarn 15 is distributed across each portion of bundle strand conductor 12.
