Abstract
Insulation tubing (66) having adjustable dimensions is disclosed. The insulation tubing has an outer tubular wall that defines a central opening for receiving the core (4) and windings (8) of a partially assembled toroidal transformer. The wall is formed by preformed sections (44, 62) of electrical insulating material (10-20). The preformed sections have overlapping surfaces that are slidably positioned relative to one another. In this way, the extent of the surfaces that overlap can be changed to alter the size of the opening such that conductive windings (8) of various sizes and configurations can be accommodated.
