新手上路，想问下哪里可以学习到电缆电气性能方面的知识及公式下载？
如Max. DC Resistance @ 20°C /Conductor AC Resistance @ 50Hz, 90°C/Inductive Reactance @ 50Hz - Trefoil/Inductive Reactance at 50Hz - Flat, Touching/Zero Sequence Impedance @ 50Hz, 20°C/Conductor Inductance/Conductor Capacitance/Insulation Resistance @ 20°C/Current Carry Capacity.
先谢谢了
