Product Instruction :
Paper covered wire by Electrical Aluminum Pole extrusion die by a certain size or drawn wire after annealing, and then in the aluminum conductor wrapped more than two or two insulating paper (including paper, telephone, cable paper, high voltage cable paper, turn insulation paper) of the winding wire, suitable for oil-immersed transformers and other electrical winding with a similar wire. Produced by the extrusion process electrical bare aluminum wire is wrapped production of the cable wire is the best material.
Paper Covered Aluminum/ Copper Wire uses two layers or several layers as the insulation layer. The wrapping direction of paper is same. And every layer paper twines conductors continually and compactly without wrinkles. Used for oil-immersed transformer.
Telephone Cable Paper covered aluminum wire is used in oil-immersed transformer and other similar electrical coil windings.
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.  
 
Telephone cable paper / 3M paper / MIKITOKU covered wire oil immersed transformer winding wire
Telephone cable paper covered aluminum wire, also known as plain paper covered insulated aluminum, according to customer requirements, in the aluminum conductor winding three or more layers of cable paper or telephone paper. Plain paper covered wire is oil immersed transformer coil and similar electrical coil of special material, after the immersion using temperature index of 105ºC. According to customer requirements, and can be divided into phone paper, cable paper, high voltage cable paper, paper and other winding insulation.
NOMEX Covered Rectangular/Flat Aluminum Wire:
NOMEX coated Aluminum wire produced by the flat and round, as aluminum are dissolved can be produced.
NOMEX covering corresponds to class H insulation is mainly used in the construction of condensers and capacitors. Main application of it is in shielding of cables in high temp. environment (200°C) such as dry type transformers, military and aerospace cables. NOMEX covered conductors are more effective in condition where temperature resistance and dielectric strength requirements are high.
    By extrusion of bare aluminum wire wrapped and NOMEX Paper covered wire, the mechanical performance and electrical performance better, instead of making difficult composite enameled flat wire, suitable for transformer, winding of lifting electromagnet, electric welding machine and other products.
