Please pay within 24hrs of winning.Dielectric grease is electricallyinsulatingand does not break down when high voltage is applied. It is often applied toelectrical connectors, particularly those containing rubber gaskets, as a means of lubricating and sealing rubber portions of the connector withoutarcing.
A common use of dielectric grease is in high-voltage connections associated with gasoline engine spark plugs. The grease is applied to the rubber boot of the plug wire. This helps the rubber boot slide onto the ceramic insulator of the plug. The grease also acts to seal the rubber boot, while at the same time preventing the rubber from becoming stuck to the ceramic. Generally, spark plugs are located in areas of high temperature and the grease is formulated to withstand the temperature range expected. It can be applied to the actual contact as well, because the contact pressure is sufficient to penetrate the grease film. Doing so on such high pressure contact surfaces between different metals has the advantage of sealing the contact area against electrolytes that might cause rapid deterioration fromgalvanic corrosion.
Another common use of dielectric grease is on the rubber mating surfaces or gaskets of multi-pin electrical connectors used in automotive and marine engines. The grease again acts as a lubricant and a sealant on the nonconductive mating surfaces of the connector. It is not recommended to be applied to the actual electrical conductive contacts of the connector because it could interfere with the electrical signals passing through the connector in cases where the contact pressure is very low. Products designed as electronic connector lubricants, on the other hand, should be applied to such connector contacts and can dramatically extend their useful life.Polyphenyl Ether, rather than silicone grease, is the active ingredient in some such connector lubricants.
Silicone grease should not be applied to (or next to) any switch contact that might experiencearcing, as silicone can convert tosilicon-caroffereunder arcing conditions, and accumulation of the silicon-caroffere can cause the contacts to prematurely fail. (British Telecom had this problem in the 1970s when silicone Symel® sleeving was used in telephone exchanges. Vapor from the sleeving migrated to relay contacts and the resultant silicon-caroffere caused intermittent connection.)
