Overview
Traditional lubricants have played an important role in the operation of electrical power transmission and distribution equipment. However, today’s equipment is being designed for tomorrow’s extended maintenance intervals needing a much longer trouble-free operating life, and requiring more than traditional lubricants can deliver.
Traditional lubricants have played an important role in the operation of electrical power transmission and distribution equipment. However, today’s equipment is being designed for tomorrow’s extended maintenance intervals needing a much longer trouble-free operating life, and requiring more than traditional lubricants can deliver.
Nye offers the highest performance synthetic lubricants that meet today’s OEM design and specification requirements, and extends into tomorrow’s need for longer maintenance intervals involving both new equipment designs, as well as upgrading existing equipment currently in operation. Nye synthetic lubricant formulations not only minimize component friction and wear to ensure free mechanical operation, but also offer superior protection from aggressive environments, preventing component corrosion/oxidation that could otherwise develop into electrical resistivity problems over time.
