EVENTS NEWS COMPANY APPLICATIONS CONTACTS TRANSFORMERS IN OIL The cores are built with cold-rolled grain-oriented laminations with low specific losses. They are calculated to obtain a minimum residual flux, a reduced inrush current and a low sound level. The insulation between the laminations is obtained with carlyte, an inorganic oxide absolutely insensitive to high temperatures. The material is carefully handled in order to minimize air gaps. The windings are made of high conductivity electrolytic copper conductors and insulated in pure cellulose paper. The types normally constructed are layered, helical, disc, foil. For medium tensions, the layered or disc types are adopted and are designed and built in such a way as to ensure a uniform distribution of atmospheric or plant stresses. For low voltages, helical or foil types are used and their construction is such as to ensure excellent resistance to short circuit stress. Oil The insulating oils normally used are: Mineral oil obtained from the fractional distillation of crude oil. Characteristics of this type of liquid is that it does not contain inorganic acids, alkalis, dissolved sulfur, asphaltic products, vegetable or animal oils or other impurities. Silicone oil. This type of oil in addition to having an excellent insulating power, has the particular characteristic of extinguishing and not spreading the flame. The insulators, made of brown porcelain, according to Unel standards, are easily replaceable in case of breakage.
