Thumela I-imeyiliIzintambo zasemoyeni ezihlanganisiwe ze-Medium Voltage zisetshenziselwa kakhuluimigqa yesibili ephezuluezigxotsheni noma njengeziphakeli ezakhiweni zokuhlala.
Okujwayelekile:
I-IEC 60502-2---- Amakhebuli kagesi ane-insulated extruded kanye nezinsiza zawo zama-voltage akaliwe ukusuka ku-1 kV (Um = 1.2 kV) aze afike ku-30 kV (Um = 36 kV) - Ingxenye 2: Amakhebuli ama-voltages akalwe asuka ku-6 kV ( Um = 7.2 kV) kufika ku-30 kV (Um = 36 kV)
Amandla kagesi:
6.35/11kV, 19/33kV
Ukwakha :
I-Conductor Yesigaba: I-aluminium eyindilinga ehlanganisiwe yekilasi 2
Isikrini se-Conductor: Isendlalelo esinwetshiwe se-semi-conductive
I-Insulation: I-XLPE (i-polyethylene exhunywe ngokuphambana)
Isikrini Sokushisisa: Isendlalelo esinwetshiwe se-semi-conductive
Isikrini se-Metallic: Isikrini socingo lwethusi noma isikrini sekhasethi yethusi
Isihlukanisi: Itheyiphu evuvukalayo e-semi-conductive
Umgodla Wangaphandle: I-HDPE (i-Polyethylene Ephakeme Kakhulu)
I-Conductor Yokusekela:Izintambo zensimbi
UMBALA:
I-insulated core: Itheyiphu yokumaka eyinhloko ebomvu, ephuzi & eluhlaza okwesibhakabhaka
Umgodla ongaphandle: Mnyama
Izici:
Izinga Lokushisa Lokusebenza: 90°C XLPE
Izinga Lokushisa: -20°C PE sheath
Ithempelesha Yesifunda Esifushane( amasekhondi angu-5 ubude besikhathi esiphezulu): 250°C XLPE
I-Gonga Radius: 15 x ububanzi bubonke
