Kraft Paper Covered Ractangular/Round Aluminum/Copper Magnet Winding Strip Wire
Paper wrapped wires are special materials, It is mainly used for oil immersed Transformer, Reactor, Generator and other electric devices.. The application temperature index after impregnation is 105°C. NOMEX wrapping materials whose temperature index is 200°C are used to produce dry type transformers, According to the requirements of users, it can apply phone print paper, cable paper, high tension cable paper, interturn insulation paper and Dane release paper, etc.and Dane release paper, etc.
Product Instruction :
Paper wrapped winding wire is made up of bare from oxygen free copper rod or electrical aluminum rod by drawing or extruding processing and wrapped by insulation materials.paper covered single wire , with insulation wrapping in the outside layer
Product classification
