Kupferlitze für Volt-Transformator

The copper flexible stranded wire is made of super-quality round copper wire or tinning round copper wire,this product has passed tenacity processing,so the complete-product is soft and its outline is beautiful.The DC electrical resistivity(20°c)of copper braided wire is low than 0.0182Ω.mm2/m,the DC electrical resistivity(20°c)of tinning copper braided wire is low than 0.0193Ω.mm2/m.Notes:if having special demand GB12970.2-91,customer please contact our corporation directly TJR1 TJRX1 Type Nominal Cross Section(mm2) Calculating Cross Section(mm2)Total number of single wires No.of strands*No.of wire*layers/single wire diameter(mm) Calculated outside diameter(mm)Dcresistance at (20 °c)no higher than(Ω/km)TJR1Dcresistance at (20 °c)no higher than(Ω/km) TJRX1 Calcul Atingweight (kg/km) 2.52.41497*7/0.252.257.587.9222.74.0 3.94497*7/0.322.884.64--37.16.36.16497*7/0.403.602.97--58.01010.01497*7/0.514.591.83--94.31615.84847*12/0.496.171.16--1502525.0813319*7/0.497.350.736--239(50)48.3013319*7/0.6810.200.382--459(70)68.6418927*7/0.6812.530.269--653TJR3 TJRX3 Type Nominal Cross Section(mm2) Calculating Cross Section(mm2)No.of strands*No.of wire*layers/single wire diameter(mm) Calculated outside diameter(mmCalcul Atingweight(kg/km) 2.5 2.544*36/0.152.2242.52.393*45/0.152.122.744.034*57/0.153.238.366.046*57/0.153.7581010.0710*57/0.154.5951616.709*105/0.157.01591616.435*3*62/0.156.51562525.9814*105/0.158.52472525.766*3*62/0.15+6*57/0.158.72453535.2519*105/0.1510.03453533.0810*3*62/0.159.83153532.877*3*62/0.15+10*57/0.159.83135050.109*3*105/0.1512.0476Remark:if any other require,welcome to visit our factory for negotiating directly.
