Abstract
A toroidal transformer insulation tube includes first and second identical, molded plastic U-channel halves. The halves each have an arcuate bottom and generally semi-cylindrical sides which extend upwardly from the bottom and terminate in inner and outer edges. The edges have symmetrically arranged alternating lapped sections, radially offset from adjacent lapped sections, so that when one U-channel half is mounted to another U-channel half with their edges aligned, the lapped sections overlap to restrict relative radial and rotary motion between the U-channel halves. Thickened flanges are formed at the ends of the halves for strength and for keeping the electrical windings on the insulation tube. The flanges have lead slots, facing in opposite axial directions, formed therein for receipt of transformer leads so that the leads in opposed slots of opposed tubes are spaced apart.
