Peb qhov zoo tshaj plaws tooj liab cathodes yog tsim los ntawm kev siv thev naus laus zis tshiab. ETP (Electrolytic Tough Pitch) tooj liab yog cam khwb cia los ntawm lub siab tshaj plaws purity tooj liab cathode muaj qib "A" LME sau npe hom. Cov khoom siv zoo, ua ke nrog cov txheej txheem tsim khoom tsim nyog ua rau peb ETP tooj liab bar zoo meej rau txhua qhov kev lag luam thiab kev daws teeb meem rau txhua daim ntawv thov hluav taws xob cuam tshuam nrog tooj liab bar, busbar, busduct thiab profile.
