transformer room
2.This paper covers such important problems as earth connection,ups,super shielded transformer,earth free of power system and computer room, and methods to deal with them are also put forward.
3.and 45# transformer oils were produced from the distillate of highly paraffinic Shenbei crude by isopropanol/urea dewaxing. Dewaxing was operated at room temperature and atmospheric pressure, freezing points lower than -25 ℃ and -45 ℃ dewaxed oils and the wax contained more than 90% normal paraffins were obtained. The flash point, viscosity, acid number and electric property of the dewaxed oils after treating met the national standards of 25# and 45# transformer oils.
