So in that sense they're all dielectric grease. But the silicone grease called that (and it's quite a lot like Dow Corning stopcock grease or high vacuum grease) is so called because it's *intended* to be used for waterproofing high voltage connections rather than as a lubricant. Unless a grease is advertised as conductive (maybe loaded with metal powder) the only way to get electrical contact is for the two parts to directly contact each other. This happens at nanoscopic peaks in the surface called asperities, and bolting pressure will normally accomplish this. Yrs, d |
