Low Voltage Switch Grease

Many power distribution companies around the world have been using lubricants to protect electrically conductive switch components in a wide range of switch designs. Lubricants will extend the operating life and improve performance of electrical switches. They will protect electrical contacts from environmental and galvanic corrosion. Even in mild environments, metal oxides can gradually build up in pores on contact surfaces over time and they impede current flow. The lubricant’s primary job on sliding contacts is to separate the surfaces during operation, preventing wear and keeping debris out of the contact area, otherwise, microscopic wear particles oxidize quickly, resulting in the formation of insulators at the connection interface.

Rheotemp™ 763G is the next generation low voltage switch grease. It was developed for use on moving electrical contacts and interfaces that involve high cycle requirements, and may generate micro-arcing contributing to elevated temperatures.
