I-GZDW isitimela se-DC series panel cadmitic-nickel battery, isithintelo sokuchaja, eqeqeshwa ngezibonakaliso ezinhlelweni zokudlulisela nokulungiswa, ngezinye izikhathi ezinamandla, akukho ukungathintwa, ukunakekelwa kahle, ukuvumelanisa kwezindlela eziningi, ukuphathwa kahle, kungcono kakhulu, kuyinto isisekelo esikhulu sephakamisa se-DC. Kuyakwazi ukusebenzisa kakhulu ezindaweni ezifundazweni zokuphathwa kwezindlela zase-500KV futhi ezansi, futhi kuyakwazi ukusebenzisa kumetallurgy, umhlaba, umthombo, umklomelo kanye ne-TV, indawo yamakhompyutha, indawo yezitimela ezansi, izindlu eziningi kanye nezinye izizinda, njengoba isisekelo se-DC, isakhiwo somphakathi, ukulungiswa kwezindlela zokuphuma kwesikhathi kanye nokuphuma kwesikhathi kwesakhiwo sokuphuma kwesikhathi.
