PROBLEM TO BE SOLVED: To provide a corrosion-resistant grease composition enhancing visibility while mainly ensuring corrosion-resistance of an overhead wire, and to provide a corrosion-resistant overhead electric wire enhancing visibility by coating a surface with the corrosion-resistant grease composition or filling it at the inside while coating the surface with it. SOLUTION: In the corrosion-resistant grease composition, a luminescent substance is contained in the corrosion-resistant grease, and in the corrosion-resistant overhead electric wire, the corrosion-resistant grease composition is coated or filled to enhance the corrosion-resistance and the visibility. In the corrosion-resistant grease composition, a reflection substance can be further contained. The luminescent substance is a fluorescent substance or a light-accumulation substance. Further, a base oil preferably contains polybutene or a silicone oil as a main component. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a lubricant composition for a refrigerating machine that has excellent thermal stability and chemical stability even when including a fluorescent agent for refrigerant leakage detection.SOLUTION: A lubricant composition for a refrigerating machine comprises combining an additive into a base oil, wherein the additive is a coumarin compound. In an open type automotive air conditioning, an electric automotive air conditioning, a gas heat pump, an air conditioning, a refrigerator, a vending machine, a showcase, a hot water supply system, and a freezer such as a refrigeration and heating system that use the lubricant composition for a refrigerating machine, leakage detection of a refrigerant can be performed stably for a long period of time. Therefore, when an unsaturated fluorocarbon refrigerant with low stability is used for these various equipment, the lubricant composition for a refrigerating machine is extremely effective.
