Surface coating of lapped insulation tape

摘要

In one embodiment the present invention improves the heat flow from an electrically insulated object 13 by providing an enhanced conduit at the interface between the layers of insulating tape 16 . The tape 16 has been surface coated with a high thermal conductivity (HTC) material, so that the interface between the layers of tape 23 provides a pathway for the heat to reach the environment 24 . The radiation of heat through the tape layers is also increased by the surface coatings.
