Static dissipative electrical cable |
摘要 |
A static dissipative electrical cable which eliminates the build-up of triboelectric charging by having a carbon loaded outer jacket which is a semiconductor for draining off triboelectric charges. In one embodiment, the jacket material is a 1 megohm/ft semiconductive extrudable Teflon polyfluorinated alkoxy (PFA) resin static-dissipative polymer of low carbon-black loading (3-4% by weight) having very stable electrical/mechanical properties against temperature excursions, thermal/environmental shock and aging. The cable is designed with a double-clad aluminum/mylar foil shield that allows electrical commoning between inner and outer clads of the foil and control of the interface between semi-conductive static-dissipative jacket and the foil shield to yield a jacket-to-ground wire resistance value between 100 kilo-ohms and 50 megohms. The latter insures adequate draining of triboelectric charges to ground, while maintaining a high resistance path to any ground loop current from neighboring cables or frame ground.
