    摘要: A grease composition comprising oil, colloidal particle filler, and, optionally, a bleed inhibitor is disclosed. The grease typically has a critical yield stress below 140 Pa at 20.degree. C., preferably below 70 or 35 Pa. The grease can advantageously be used as a cable filling material, especially for optical fiber cable. In the latter case it can result in cable having substantially no cabling loss. Preferred compositions comprise 77 to 95% b.w. of ASTM type 103, 104 A, or 104B paraffinic or naphthenic oil, or polybutene oil; 2 to 15% b.w. of hydrophobic or hydrophilic fused silica; and optionally, up to 15% b.w. of styrene-rubber or styrene-rubber-styrene block copolymer, or semiliquid rubber.

    摘要: An insulating oil containing N,N-bis(2-hydroxyethyl)-N-cyclohexylamine at 0.5 mg/l or more. An electrical apparatus is filled with the insulating oil in which a copper component is immersed. During operation of the apparatus for a long period of time, the tan .delta. of the insulating oil does not increase so that deterioration of the insulating oil is deferred, thereby substantially extending the life of the insulating oil.

    摘要: A coil wire has a lubricant film formed on an outer surface of an insulation film covering a conductor. The lubricant film is made of polypropylene glycol or a material obtained by substituting a hydrogen atom at at least one end of polypropylene glycol with another reactive group so as to provide a coil wire wherein generation of organic gases can be suppressed.
