Description

A mobile wind energy cable

Technical field:

The utility model relates to a mobile wind energy cable for wind power generation, in particular for connecting a wind power generator with the ground, and belongs to the field of new cable technology.

Background technique

At present, wind energy, as a clean and renewable energy, has received more and more attention from various countries, and its reserves are huge. The global wind energy is about 2.74×10 ⁹ MW, of which the available wind energy is 2.74×10 ⁷ MW. The total amount of water energy that can be developed and utilized on the earth is 10 times larger.

In recent years, the world wind energy market has grown at a rate of 40% every year. It is estimated that in the next 20-25 years, the world wind energy market will grow at a rate of 40% every year. With the advancement of technology and the development of environmental protection, wind power generation will be fully competitive with coal-fired power generation commercially.

China's wind power industry is developing rapidly, but there is still a big gap with the development level of the international wind power industry. Domestic wind power equipment is mainly imported and has a strong dependence on foreign countries. Although the cost of wind power has dropped a lot, the advantage over thermal power costs is in the short term. It will not be obvious, and there are still many obstacles to the development of the wind power industry. Among them, the high manufacturing cost of wind energy cables is also an important factor affecting the rapid development of wind power.

Contents of the invention

The purpose of this utility model is to solve the current problem of lack of wind power cables, and provide a flexible wind power cable with low temperature resistance, oxidation resistance, high temperature resistance, easy torsion and low cost.

The utility model provides a mobile wind energy cable. The structure of the cable from the inside to the outside is a conductor, an isolation layer, an insulation layer and a sheath layer. The isolation layer is coated on the surface of the conductor, and the insulation layer is coated on the surface of the isolation layer. The cable core, and the sheath layer is extruded on the surface of the cable core.

The above-mentioned insulating layer adopts irradiated ethylene-propylene flame-retardant elastomer insulating material, and the sheath layer adopts irradiated ethylene-propylene flame-retardant elastomer sheath material. The material selection and collocation scheme of this structure are novel and special.

The utility model has the advantages of reasonable and simple structure, easy manufacture, low cost and no pollution. The cable has strong flexibility, elasticity, recoverability, tensile strength and low temperature resistance, and can withstand 3600 twisting tests. The mobile wind power cable has a compact and round structure, is safe to use, and can fully meet the performance requirements of today's wind power cables. This product is dedicated to domestic and foreign wind farms and has good environmental and economic benefits.
