Effects of striations on magnetization loss of transposed coated conductors

Even though a coated conductor is more superior in some performances than a BSCCO PIT wire, its AC loss is still high. One of the solutions to decrease the AC loss of the coated conductor is to make striations on it and to twist it. But we cannot use the twisted single coated conductor for a winding of an AC machine. Instead of the twist, the transposed coated conductors which have striations on themselves can be used. To estimate the effect of magnetization loss reduction, several short samples having or not having striations and transposition are prepared. Each sample is tested in perpendicular external magnetic fields. Test results of several samples with a striation and transposition give the possibility on lower magnetization loss.
