Abstract
The utility model relates to a thermal-shrinkage mesh coated transposed conductor wire with a radiating oil passage for extra-high voltage converter transformers, belonging to the technical field of transformer manufacturing. The technical scheme includes that the thermal-shrinkage mesh coated transposed conductor wire comprises transposed conductor wires, radiating oil passages and a thermal-shrinkage mesh belt (4), each single transposed conductor wire (3) consists of two rows of flat enameled copper wires, the radiating oil passage is disposed in the middle of the single transposed conductor wire (3), and the thermal-shrinkage mesh belt is uniformly lapped on the outer side of the transposed conductor wire. As the radiating oil passage is disposed in the middle of the transposed conductor wire, oil flow is utilized sufficiently and radiating capacity of windings is increased greatly. The uniform lapping of the thermal-shrinkage mesh belt replaces the conventional insulating paper lapping, and the windings can contact with transformer oil directly, thereby increasing radiating capacity while reducing size of the transposed conductor wire. The thermal-shrinkage mesh belt is woven by polyester or mixture of polyester/glass fibers, can generate high shrinkage when heated so as to force the single flat wires in the transposed conductor to be combined tightly, thereby increasing mechanical stability of the windings.
