Abstract
The invention relates to a three-core control cable which comprises three equant wire cores, wherein the insulating wire cores consist of conductors and insulating layers and shield layers which are sequentially arranged outside the conductors; the three insulating wire cores jointly extrude a warping tape to form a cable core; an inner protection layer is arranged outside the cable core; an armor layer is arranged outside the inner protection layer; and an outer sheath is arranged outside the armor layer. The control cable is simple in structure, low in production cost and long in service life.
Description
Technical field
The present invention relates to a kind of cable, relate in particular to a kind of three core control cables.
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 for overcome the above problems provide a kind of simple in structure, production cost is low, three core control cables of long service life.
Technical scheme of the present invention is: described control cables comprises that three grades divide the core of setting, insulating barrier and screen that described core is set gradually outward by conductor and conductor form insulated wire cores, three described insulated wire cores jointly extrude twining package tape and form cable core, described cable core is provided with sheath outward, this sheath is provided with armour outward, and described armour is provided with oversheath outward.
Described insulating barrier is crosslinked polyetylene insulated layer.
Described screen is braided steel wire screen.
Described twining package tape is the vertical band that holds of plastic-aluminum.
Described armour is copper strips armour.
The present invention is simple in structure, production cost is low, long service life.
