Paramount Tube offers a unique tube adaptation process called “Bow” for square and rectangular tubes. Bow is defined as a tube having sides that are convex, meaning that the sidewalls of the tube are slightly curved away from the center of the tube. Paramount Tube offers four different degrees of
bowed sidewalls; Paraformed, Very Slight, Slight and Regular.
The indication for use of bowed tubes is when the tube is wrapped tightly with magnetic wire during the transformer manufacturers winding process. A tightly wound coil has the ability to place a certain degree of negative pressure against the outer walls of the tube. This negative pressure can cause the walls of the inner core to collapse thus making the coil defective. If the walls collapse, the steel laminations (E shaped) cannot be properly inserted into the center of the core.
