Abstract
The utility model discloses a twist-resistant cable used for wind power generation. The cable includes three alloy conductors; the exteriors of the three alloy conductors are wrapped with silicon rubber insulation layers, such that insulation wire cores can be formed; the insulation wire cores are stranded with one another with an elastic wire core adopted as a center so as to form a cable core; aramid wires are stranded with one another and are bunched, and molded in an elastic layer through extrusion molding so as to from the elastic wire core; and the exterior of the cable core is wrapped with a wrapping layer and an outer sheath layer sequentially. According to the cable of the utility model which is novel in structure design, the insulation wire cores are distributed at the outer side of the elastic wire core, such that the cable core can be formed, and at the same time, tensile anti-tear silicone rubber is adopted as an insulation material, and therefore, the tensile performance and structural compactness of the cable can be improved, and the wire cores are not prone to fracture when the cable is installed and arranged under harsh climates, and the stability of signal transmission can be ensured, and the service life of the cable can be prolonged.
Description
Technical field:
The utility model relates to cable for wind power generation, relates in particular to a kind of twist-resistant type cable for wind power generation.
Background technology:
The energy is that the mankind depend on for existence and the material base of social development, and according to the report that the United Nations in 2001 announces, the petroleum resources of having verified in the world can only use 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 remain the mankind on the earth and go 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 has obtained paying attention to and exploitation, and the Wind Energy In China reserves have more than 1,000,000,000 kW, and development potentiality is huge.
For the cable of used for wind power generation, traditional structure is continued to use in the general structure design, therefore often occurs the signal transmission fault in actual working environment, such as, in the mounting and installation process or under harsh climate environment after the installation, the cable core fracture often appears.
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 twist-resistant type cable for wind power generation, and structural compactness is good, and the stretch-proof performance of cable is superior, is applicable to use in the environment of awful weather the stability of inhibit signal transmission.
Technical scheme of the present utility model is as follows:
The twist-resistant type cable for wind power generation, comprise three alloy conductors, it is characterized in that: described three alloy conductors all wrap up silicone rubber insulation layer outward and consist of insulated wire cores, insulated wire cores mutual stranded bunchy centered by elastic core consists of cable core, elastic core adopts the aramid fiber tow to consist of in elastic layer through extrusion moulding, elastic layer thickness is not less than 2.2mm, and cable core is coated with belting layer, external sheath layer outward successively.
Described twist-resistant type cable for wind power generation is characterized in that: described three alloy conductor cross sections are generally 1.6～280mm
2
Described twist-resistant type cable for wind power generation is characterized in that: described elastic layer adopts the organosilane crosslinked polyethylene extrusion moulding to consist of, and external sheath layer adopts polyether-type thermoplastic polyurethane compound material extrusion moulding to consist of.
The utility model has the advantages that:
The utility model structural design is novel, consist of cable core by insulated wire cores being distributed in the elastic core outside, adopting simultaneously tension to tear silicon rubber is insulating material, stretch-proof performance and the structural compactness of cable have been improved, guarantee that cable is under the harsh climate environment and in the mounting and installation process, core is easy fracture not, ensures that signal transmits stability, has prolonged useful life.
