Abstract
The invention relates to a 220KV extra high voltage power transmission cable. The cable comprises a conductor. An inner insulating layer is arranged outside the conductor, and the conductor is provided with a wrapping tape through extrusion to form a wire core. Filler is arranged in the wire core. A metal braid shielding layer, an outer insulating layer and an outer sheath are arranged outside the wire core successively. According to the invention, advantages of simple structure, stable power transmission, low smoke, flame-retardant performance and long service life can be realized.
Description
Technical field
The present invention relates to a kind of power cable, relate in particular to a kind of 220KV ultrahigh voltage power transmission cable.
Background technology
Along with the develop rapidly of China's economy, the skyscraper of China, subway, nuclear power station, shipbuilding industry, photoelectron communication etc. develop at a speed unheard of before especially, and the consumption of electric wire also increases rapidly thereupon.
Summary of the invention
The present invention provides in order to overcome the above problems that a kind of simple in structure, electric power transfer is stable, the 220KV ultrahigh voltage power transmission cable of low-smoke and flame retardant, long service life.
Technical scheme of the present invention is: described cable comprises conductor, and described conductor arranges inner insulating layer outward and extrudes twining package tape and forms core, in described core, is provided with filling, and described core sets gradually metal knitted screen, external insulation layer and oversheath outward.
Described conductor is copper conductor, and this copper conductor is wound around bunchy counterclockwise by some copper wires.
Described inner insulating layer and external insulation layer are crosslinked polyetylene insulated layer.
Described oversheath is polyvinyl chloride oversheath.
Described be filled to fire-retardant filling.
The present invention is simple in structure, electric power transfer is stable, low-smoke and flame retardant, long service life.
