Amathrendi embonini nengemuva lemakethe
Ngokuvumelana neIEEMAfuthiMarketsandMarkets, imakethe ye-switchgear ye-low-voltage kulindeleke ukuthi idluleI-USD 60 billion ngo-2030, ishayelwa ngu:
- Ukwamukelwa kwesakhiwo esihlakaniphile
- Igridi yesimanje kanye nokwabiwa kwamazwe
- Ukunyuka kwesidingo sokusebenza kahle kwamandla
- Ukwandiswa kwengqalasizinda yasemadolobheni
Emisha efanaI-switchgear enikwe amandla yi-IoT,imiklamo modular, futhiUkuxilongwa kwephutha okusekelwe ku-AIbaphusha izinhlelo ze-LV zendabuko endaweni yokuphathwa kwamandla edijithali.
IEEE ejwayelekileC37.20.1kanye nezinga le-IEC61439-1lawula ukwakheka, ukuphepha, kanye nokuhlolwa kwe-switchgear ene-low-voltage emhlabeni jikelele.
