Filed: 1991-06-12
Abstract: PURPOSE:To spread a substance, the electrical characteristic of which is deteriorated, contained in insulating oil injected into a connecting section in an absorbent so as to prevent the deterioration of the insulating oil and maintain excellent electrical characteristics by bringing the absorbent into contact with the insulating oil. CONSTITUTION:The connecting section of an OF cable is formed by a normal method by using, for example, a connecting box 8. Alkyl benzene is used as insulating oil. The alkyl benzen is thermally deteriorated by heating the benzen while the benzen is brought into contact with a copper catalyst. The thermally deteriorated benzen is injected into the connecting box 8 by about 10l through the connector of the box 8 and, at the same time, about 5kg of viscous activated alumina is put in the box 8. When the inductive tangent of the insulating oil in the box is measured after the connecting section is maintained at 40 deg.C for 60 days, the value of the inductive tangent of the thermally deteriorated oil is reduced and maintained at about 0.05%. In other words, the substance which is contained in the insulating oil in the connecting section and deteriorates the electrical characteristic of the insulating oil can be removed by adsorption and, as a result, the oil can maintain its excellent electrical characteristic.
