Low voltage distibution cubicles (400 V)
Construction and assembly of Eaton Holec Tabula circuit breaker cubicles. Production of numerous main distribution boards (MDB) and motor control centres (MCC) during the past decades.
Framleiddar hafa verið fjölmargar aðaltöflur (MDB) og mótordreifitöflur (MCC) undanfarin 25 ár. Orkuvirki hefur einnig verið með framleiðslu á eigin rofaskápum fyrir “listarofa”, sem einkum hafa gagnast rafveitum.
Low voltage distribution boards
Orkuvirki has imported low voltage distribution cubicles from the Danish manufacturer Eaton-Holec, of the type Tabula, during the past 20 years. Numerous panels using the cubicles have been assambled. Main distribution boards (MDBs), motor control centres (MCCs) and subdistributions are in use in power plants, industrial installations, etc. all over Iceland.
The main characteristics of the Tabula circuit breaker cubicles are: – Type tested 690 V (400/230 V) circuit breaker cubicles, 260 to 7.800 A – Tested in accordance with IEC/EN 60439-1 og -3.
– 600/1.000 V, (2/3,5 kV)
– 276 kA (peak), 120 kA (1 sek)
