Abstract
The inventions relates to a surface-treated cooled wire and to the field of overhead conductors, and specifically to a novel cooled wire with a surface coated with high-radiation lowly-endothermic coating. The surface-treated cooled wire comprises central reinforcing cores, conductors, and an outermost coating. The conductors are stranded on the outer side of the central reinforcing cores and are coated with the outermost coating. The outermost coating is a high-radiation lowly-endothermic coating layer and is a fluorocarbon coating containing fluorocarbon element. The surface-treated cooled wire is easy to manufacture, low in cost increase, decreased in used temperature, and resistant to weather and corrosion. The outermost coating forms a permanent layer with high-radiation lowly-endothermic coating on the surface of the surface-treated cooled wire. Compared with a wire with same specification, the novel surface-treated cooled wire is decreased in surface temperature by 5 to 20 degrees centigrade in the case of same current-carrying capacity. As a result, line energy loss in a transmission process is reduced and low-carbon economy is achieved.

The weatherability that described outermost layer coating adopts, the coating of anti-corrosion type, coating has high chemical inertness, therefore under various complicated harsh weather and environment, uvioresistant, colour-fast, not easily aging, coating surface can be made to keep uniform color for a long time, the situation such as there will not be explosion, peel off.Meanwhile, in weatherability, anti-corrosion type coating, fluorine-containing polymer is difficult to chemical reaction occurs, and therefore coating is not by the erosion of most of chemical substance, and coating is not broken up, and can effectively protect aluminum steel and steel core not to be corroded.
Surface treatment type cooling wire is compared with the wire of other kinds, its feature performance benefit had is: surface treatment type cooling wire is due to the weather-resistant type anticorrosive paint of its surface spraying height radiation, low heat absorption color, conductive line surfaces operating temperature can be reduced, reduce the energy loss in line transmission process, improve the ampacity of wire; Simultaneously because wire outermost layer is coated with one deck coating, not only reduce the mirror-reflection of wire, more effectively can carry out corrosion protection to wire, be applicable to the area that acid and alkali corrosion is serious.
Characteristic feature of an invention:
1, wire outermost layer sprays the coating of high radiation, low heat absorption color, on the indeclinable basis of mechanical performance ensureing wire, reduces conductive line surfaces temperature 5 DEG C ~ 20 DEG C.
2, the coating of outermost high heat loss through radiation, low heat absorption color, the light harm that the mirror-reflection solving wire outer surface brings.
3, the fluorine-containing polymer in coating is difficult to chemical reaction occurs, and not by the erosion of most of chemical substance, coating is not broken up, and has remarkable heavy antisepsis performance.
4, the fluorine element electronegativity in coating is large, and carbon-fluorine bond can be strong, and have unique not viscosity and low abrasiveness coating, self-cleaning function is strong.
5, in coating, carbochain is tightly surrounded by adjacent fluorine atom, forms very strong screen effect, is chemically showing as high chemical inertness.There is the weatherability of very overlength.
