Uchungechunge lwe-S11, S13, S20, S22-M oluvalwe ngokugcwele isiguquli samandla esicwiliswe uwoyela esakhiwe futhi esikhiqizwa inkampani yethu sinezinzuzo zokulahlekelwa okuphansi, umsindo ophansi nokusebenza kahle okuphezulu, okungafinyelela umphumela omuhle wokonga amandla nokunciphisa ukungcola. I-transformer evalwe ngokugcwele kanye ne-transformer evamile ecwiliswe uwoyela, uma iqhathaniswa nokuqedwa kwekhabhinethi yokugcina uwoyela, ukuguqulwa kwevolumu kawoyela ngethangi likawoyela likathayela ishidi lokunwebeka kokulungiswa okuzenzakalelayo ukunxephezela i-transformer ehlukanisiwe nomoya ukuvimbela nokunciphisa ukuwohloka kukawoyela kanye nokuguga kokuguga, kuthuthukise ukuthembeka kokusebenza okuvamile, ukusebenza kwamahhala.
