Abstract

a. L'invention concerne des condensateurs comprenant des couches de feuilles métalliques alternant avec un écarteur diélectrique imprégné d'un fluide diélectrique. b. Le fluide diélectrique qui imprègne l'écarteur diélectrique placé entre les feuilles métalliques est constitué de 25 à 100 % en poids de di-isopropyl biphényl, de 0 à 80 % en poids de mono-isopropyl biphényl et de 0 à 20 % en poids de triisopropyl biphényl. c. Les condensateurs ainsi fabriqués résistent, dans des limites acceptables commercialement, aux surtensions et à l'effet couronne, et font preuve d'une bonne résistance à la cristallisation aux basses températures.at. The invention relates to capacitors comprising layers of metal foils alternating with a dielectric spacer impregnated with a dielectric fluid. b. The dielectric fluid which impregnates the dielectric spacer placed between the metal sheets consists of 25 to 100% by weight of di-isopropyl biphenyl, 0 to 80% by weight of mono-isopropyl biphenyl and 0 to 20% by weight of triisopropyl biphenyl. vs. The capacitors thus manufactured resist, within commercially acceptable limits, overvoltages and the corona effect, and demonstrate good resistance to crystallization at low temperatures.
