Thumela i-imeyiliIzintambo ezihlanganisiwe ze-aerial Voltage Ephakathi zisetshenziswa kakhuluimigqa yesibili ephezuluEzigxotsheni noma njengezinto zokuphakelayo ezindaweni zokuhlala. Iphinde isetshenziswe ekudluliseni ugesi usuka ezigxotsheni zikagesi uye ezakhiweni. Inikeza ukuphepha okuphezulu nokuthembeka, imelana nezimo zezulu ezinzima, imisebe ye-ultraviolet, kanye nokucindezeleka komshini. Kulula ukuyifaka nokuyinakekela, ngezindleko zokusebenza eziphansi, ivame ukusetshenziswa ekusabalaliseni ugesi ezindaweni zasemadolobheni nezasemakhaya.
Okujwayelekile:
IEC 60502-2---- Izintambo zikagesi ezine-insulation ekhishwe kanye nezesekeli zazo zama-voltage alinganiselwe kusuka ku-1 kV (Um = 1.2 kV) kufika ku-30 kV (Um = 36 kV) - Ingxenye 2: Izintambo zama-voltage alinganiselwe kusuka ku-6 kV (Um = 7.2 kV) kufika ku-30 kV (Um = 36 kV)
