Kraft paper-wrapped aluminum wire is a kind of winding wire, the conductor is made by extruding the electric round aluminum pole, winding two or more layers of kraft paper on the conductor, the thickness of insulation is 0.30-0.50 mm, most of the kraft paper-wrapped aluminum wire is used for oil-immersed transformer winding.
1. Conductor Material
φ9.5mm/12.0mm Electrician aluminum rod. Kraft paper covered aluminum wire Used 9.5mm electrical round aluminum rod, alloy grade 1350/1370, aluminum content ≥99.7%, resistance ≤0.0280 Ωmm²/m(20ºC). In order to ensure the resistance of the enameled aluminum round wire, we use high-quality electrical aluminum rods raw materials, aluminum content > 99.7%, sufficient length to reduce welding times.
