ELECTRICAL INDUCTIVE APPARATUS

摘要

An arrangement for supporting a winding tube of a power transformer. The winding tube is supported and held in position by a supporting structure constructed of rigid plastic foam. Spaces or openings in the supporting structure, which are created by suitably shaped members, permit the liquid dielectric of the transformer to flow through the supporting structure to cool adjacent structures. The suitably shaped members are inserted between the winding tube and its supporting member before the plastic foam is placed therein, thereby defining the shape of the spaces or openings in the supporting structure.
