GZDW fa'asologa maualuga-telefoni suiga DC power supply panel o se seti atoatoa o DC power supply masini fuafuaina ma gaosia e la tatou kamupani e tusa ai ma GB / T 19826-2005 ma DL / T459-2002 tulaga fa'atasi ma tausaga o poto masani fa'aputuga ma faiga faiga. pulega. O se faiga fa'aletino mana'omia DC mo faiga fa'asoa eletise o iai nei.
Ua faʻaaogaina lautele i substations ma switchstations o tulaga eseese voltage mai le 500KV i le 10KV, afi eletise o 15MW i 60MW generator seti, galuega autu a le atunuu, e pei o subways, fanua suauu, alamanuia kemisi, metallurgy, ma isi, e pei o le pulea, faailoilo. , faʻalavelave faʻafuaseʻi ma isi avega i lalo o tulaga masani ma faʻalavelave faʻafuaseʻi o le eletise DC, lea e mafai ona le faʻaogaina. O le mea sili lea e suitulaga i meafaigaluega fa'aola DC masani.
