AIR INSULATION TYPE ELECTRIC POWER BUSWAY DUCT IMPROVED THERMAL RADIATION EFFICIENCY

摘要

PURPOSE: An air insulation type electric power bus duct is provided to maximize thermal radiation efficiency by forming a coating layer in the outer surface of a busbar and the inner and outer surface of a case. CONSTITUTION: A plurality of bus bars(300) are made of copper or aluminum. A plurality of bus bars passes through the inside of a case(200). A space part is formed between busbars and between the bus bar and the case. A coating layer(301,201,202) is formed in the outer surface of the busbar and the inner and outer surface of the case. The coating layer is made of non-conductive material. The coating layer has a thickness of 0.1mm to 1.5mm.
