Abstract
An electrical wiring material having a cooling function is characterized by a long hollow conductive body within which operating fluid is internally confined. An electrical connection piece is provided at the end portions of the conductive body, or other portions thereof. When used to wire electronic apparatuses, resulting heat is radiated due to evaporation and condensation of the operating fluid within the hollow conductive body. The wiring material may be used to wind a transformer, particularly the low voltage side, to provide a self cooling transformer.
