Said inner covering is a double-decker, comprises the mica tape and the outer field glass fabric of nexine.
Said core belting layer adopts glass fiber tape.
Said line set of shield layer adopts tinned copper wire.
Said armour adopts zinc-coated wire.
Said insulating barrier adopts mica tape.
Said outer jacket is a glass fiber.
The said master core that is made up of conductor, insulating barrier, glass fiber braid of the utility model is single core or many cores, and the arrangement mode of its many cores is the single or multiple lift concentric stranding.
The thickness of the described insulating barrier of the utility model is 0.3-0.4mm, and the thickness of glass fiber braid is 0.2-0.3mm.
The advantage of the utility model is in particular in the following aspects:
One, at insulating barrier outerwrap glass fiber braid; Guaranteed that the high-temperature field share the insulating properties of compensating cable, anti-flammability, heat-resisting quantity and fire resistance; Compare with common compensating cable and to have good heat-resistance property, 800 ℃ ± 20 ℃ of experimental conditions, operation conditions is good.
Two, screen adopts tinned copper wire, and when the frequency of interfere with electromagnetic field was higher, the eddy current that can utilize its screen to produce formed and externally comes electromagnetic negative function, thereby reaches the effect of shielding; Line set of shield layer can effectively shield the phase mutual interference when compensating the signal transmission between each line group, has guaranteed each accuracy to line group transmission signals.
Three, at glass fiber braid outerwrap core belting layer, the injury of screen be can prevent, conductor and insulating barrier protected effectively insulated wire cores.
Four, armour adopts the materials such as zinc-coated wire possess high permeability, and except possessing the tension effect, when disturbing electromagnetic frequency low, plating core wire braid also can make the magnetic line of force be limited in shield inside, prevents that the space that is diffused into shielding from going.
Five, inner covering is a double-decker, comprises the mica tape and the outer field glass fabric of nexine, has greatly improved the anti-flammability and the heat-resisting quantity of cable, thereby has promoted fail safe and useful life that cable uses.
