The combined use of stranded and solid wires enhances the performance of electric machine20. Solid wire40is an efficient conductor of DC current but when positioned near rotor22in slot36, it experiences relatively greater AC losses than a stranded wire due to the skin effect discussed above. At...
of the tape. Where phase versus temperature requirements are critical, Harbour’s LL cables allow for an approximately 75% lower phase shift and change in propagation time delay due to temperature. Temperature cycling tests have been performed on a number of Harbour’s cables with positive results...
As shown in Figure 5, transmission line conductors are not solid, but stranded, which makes the physics of the problem more complex. Figure 5. Cross-section of a stranded bare conductor. According to [20,22], in multilayer stranded conductors, most of the i2rAC heat flow is conducted ra...
