Abstract

The utility model relates to an overhead wire cable, and specifically relate to a self-damping overhead wire. The self-damping overhead wire includes an inner core wire formed by stranding a galvanized steel wire, an aluminum-plated steel wire and an aluminium-covered steel wire and three conductive metal wire layers located outside the inner core wire, wherein the three conductive metal wire layers are successively a No. 1 conductive metal wire layer, a No. 2 conductive metal wire layer and a No. 3 conductive metal wire layer from inside to outside; and gaps are between the inner core wire and the No. 1 conductive metal wire layer and among the three conductive metal wire layers. The inner diameters of the three conductive metal wire layers are greater than the outer diameter of the inner core wire. The inner core wire can withstand high tension, so that the wire has sufficient strength, and can effectively prevent vibration to reduce strand breaking and other accidents of the overhead wires.

Description

The self-damping aerial condutor

Technical field

The utility model relates to a kind of aerial condutor cable, specifically, relates to a kind of self-damping aerial condutor.

Background technology

The carrier that aerial condutor is carried as electric power occupies very consequence in transmission line.In actual applications, gentle breeze causes that the vibration of aerial condutor is the ten minutes general phenomenon, if wind speed lower (1-30 kilometer/hour), peak value and the amplitude of aerial condutor vibration are also lower, amplitude is similar with the diameter of lead approximately, and its frequency range is wideer, and it is conspicuous to be about 2-200.When wire tension increased, lead also increased because of the trouble that vibration causes thereupon.At present, prevent that the device of aerial condutor vibration from mainly being stockbridge damper and damping wire, still, these two kinds of devices fail to eliminate to greatest extent or reduce the vibration of aerial condutor.

The utility model content

The purpose of this utility model is, provides a kind of self-damping aerial condutor, to solve the problems of the technologies described above.

For addressing the above problem, the technical scheme that the utility model adopts is:

A kind of self-damping aerial condutor, it is characterized in that: comprise the internal core wire that is formed by galvanized steel wire, aluminium plating steel line or aluminium-clad steel wire strand system and three conductive metal wire layers that are located at the internal core wire outside, described three conductive metal wire floor are a conductive metal wire floor, No. two conductive metal wire floor and No. three conductive metal wire floor from inside to outside successively; Between described internal core wire and the conductive metal wire floor, and all there is the gap between three conductive metal wire layers.

Beneficial effect: compared with prior art, the internal diameter of three conductive metal wire layers in the internal core wire described in the utility model outside is bigger than the external diameter of internal core wire, internal core wire can bear very high tension force, make lead have enough intensity, can prevent the generation vibrated more effectively, to reduce the accidents such as disconnected thigh of aerial condutor.

Description of drawings

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

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

With reference to Fig. 1, self-damping aerial condutor described in the utility model comprises the internal core wire 1 that is formed by galvanized steel wire, aluminium plating steel line or aluminium-clad steel wire strand system and three conductive metal wire layers that are located at internal core wire 1 outside.Described three conductive metal wire floor are a conductive metal wire floor 2, No. two conductive metal wire floor 3 and No. three conductive metal wire floor 4 from inside to outside successively.Between described internal core wire 1 and the conductive metal wire floor 2, and all there is the gap between three conductive metal wire layers.
