I-IEC BS Standard 12-20kV-XLPE Insulated PVC sheathed MV Power Cable
Ifanele amanethiwekhi wamandla njengeziteshi zikagesi.Ukufakwa emiseleni, ngaphansi nangaphandle.
Kunokwehluka okukhulu kwezokwakha, amazinga kanye nezinto ezisetshenziswayo - ukucacisa ikhebula le-MV elilungile lephrojekthi kuyindaba yokulinganisa izidingo zokusebenza, izimfuno zokufakwa, nezinselelo zemvelo, bese siqinisekisa ukuthi ikhebula, imboni, kanye nemithetho iyahambisana.Njengoba i-International Electrotechnical Commission (IEC) ichaza amakhebuli e-Medium Voltage njenganesilinganiso samandla kagesi angaphezu kuka-1kV afika ku-100kV okuyibanga elibanzi lamandla kagesi okufanele licatshangelwe.Kujwayeleke kakhulu ukucabanga njengoba senza mayelana ne-3.3kV kuya ku-35kV, ngaphambi kokuthi ibe namandla kagesi aphezulu.Singakwazi ukusekela ukucaciswa kwekhebula kuwo wonke ama-voltages.
