Description
Technical field
The utility model relates to a kind of screened film, particularly relates to a kind of anticorrosion screened film being applied to coaxial cable.
Background technology
What is called shielding on the construction of cable is in fact a kind of measure improving Electric Field Distribution.Cable conductor forms by stranded conductor is stranded, and easily form air gap between it and insulating barrier, conductive surface is rough, and electric field can be caused to concentrate.Add the screen of one deck semiconductive material at conductive surface, the conductor equipotential of it and conductively-closed, and with insulating barrier good contact, thus avoid, between conductor and insulating barrier, partial discharge occurs.This one deck shields, and is also called internal shield.In insulating surface and sheath contact position, also may there is gap, during cable bend, oil paper cable insulating surface easily causes crackle, and these are all the factors causing partial discharge.Add the screen of one deck semiconductive material at surface of insulating layer, the insulating barrier of it and conductively-closed has good contact, with metallic sheath equipotential, thus avoids, between insulating barrier and sheath, partial discharge occurs.
What traditional cable shielding film adopted is the semiconductor structure that two-layer aluminium foil layer sandwiched plastic layer is formed, and the shield effectiveness of this kind of screened film is poor, and when cable serving is damaged, screened film directly can be subject to extraneous corrosion, cause namely being corroded in the short time damage, have influence on the normal use of cable, limit the useful life of cable.When especially relating to submarine cable, because the salinity of seawater is higher, the submarine cable moment is in the stronger environment of a kind of corrosivity, and its screened film is easy to be corroded, and has influence on the useful life of submarine cable.
