METHOD TO PREVENT SLUDGE FORMATION AND PREVENT COLOR BLADE IN A CONTAINER FILLED WITH REFINED MINERAL OIL, AT LEAST PARTIALLY TRANSPARENT |
| abstract |
An oil-soluble substance (A) which absorbs UV and short-wavelength visible light =4500 A is added to refined mineral oils to prevent formation of sludge and bleaching of markings inside oil level indicators, etc. by the action of light. (A) is pref. a deriv. of benztriazole, esp. a 2-hydroxyphenyl benztriazole derivs., in amount of 0.1-5 wt. % of the oil. The process is suitable for use in electrical equipment e.g. oil filled switches and transformers situated outdoors, and the colour and electrical props of the oil are not adversely affected while heat resistance may even be improved. |
