Ikhebula lamandla kagesi eliphakathi nendawo
-
AS/NZS standard 12.7-22kV-XLPE Insulated MV Power Cable
Ikhebuli yokusabalalisa ugesi noma amanethiwekhi amancane wokudlulisa ngokuvamile asetshenziswa njengokuphakelwa okuyinhloko Kumanethiwekhi Ezohwebo, Izimboni kanye nezindawo zokuhlala zasemadolobheni.Ifanele amasistimu amaphutha aphezulu alinganiselwe kufika ku-10kA/1sec.Ukwakhiwa okukalwe okunephutha eliphezulu kuyatholakala ngesicelo.
Izintambo eziklanywe ngokwezifiso ze-Medium Voltage
Ukuze usebenze kahle nokuphila isikhathi eside, yonke ikhebula ye-MV kufanele ifanelane nokufakwa kodwa kunezikhathi lapho kudingeka khona ikhebula le-bespoke ngempela.Ochwepheshe bethu bekhebula le-MV bangasebenza nawe ukuze baklame isixazululo esihambisana nezidingo zakho.Ngokuvamile, ukwenza ngokwezifiso kuthinta usayizi wendawo wesikrini se-metallic, esingalungiswa ukuze kushintshwe umthamo wesekethe emfushane kanye nokuhlinzekwa komhlaba.Kuzo zonke izimo, idatha yobuchwepheshe inikezwa ukukhombisa ukufaneleka kanye nencazelo ecijile ukuze yenziwe.Zonke izixazululo ezenziwe ngokwezifiso zingaphansi kokuhlolwa okuthuthukisiwe esikhungweni sethu sokuhlola ikhebula le-MV.
Xhumana nethimba ukuze ukhulume nomunye wochwepheshe bethu.

I-IEC/BS Standard 18-30kV-XLPE Ikhebula Lamandla Lamandla Ephakathi Le-MV Engafakiwe
Izintambo eziwumgogodla owodwa zenzelwe ukusatshalaliswa kwamandla kagesi ane-voltage ye-Uo/U esukela ku-3.8/6.6KV ukuya ku-19/33KV kanye nemvamisa engu-50Hz.Afanele ukufakwa kakhulu eziteshini eziphakela ugesi, endlini nasemigudwini yekhebula, ngaphandle, ngaphansi komhlaba nasemanzini kanye nasekufakweni kumathreyi ekhebula ezimbonini, ama-switchboard kanye neziteshi zikagesi.

AS/NZS standard 19-33kV-XLPE Insulated MV Power Cable
Ikhebuli yokusabalalisa ugesi noma amanethiwekhi amancane wokudlulisa ngokuvamile asetshenziswa njengokuphakelwa okuyinhloko Kumanethiwekhi Ezohwebo, Izimboni kanye nezindawo zokuhlala zasemadolobheni.Ifanele amasistimu amaphutha aphezulu alinganiselwe kufika ku-10kA/1sec.Ukwakhiwa okukalwe okunephutha eliphezulu kuyatholakala ngesicelo.
Osayizi Bekhebula le-MV:
Amakhebula ethu angu-10kV, 11kV, 20kV, 22kV, 30kV kanye no-33kV atholakala kububanzi obulandelayo bosayizi wezigaba (kuye ngokuthi amakhondaktha eCopper/Aluminium) ukusuka ku-35mm2 kuya ku-1000mm2.
Osayizi abakhulu bavame ukutholakala uma ucelwa.

I-IEC/BS Standard 19-33kV-XLPE Ikhebula Lamandla Lamandla Ephakathi Le-MV Engafakiwe
Izintambo zikagesi ezimaphakathi zenziwa kusetshenziswa inqubo ye-monosil.Sihlinzeka ngemboni ekhetheke kakhulu, izikhungo zocwaningo ezisezingeni eliphezulu kanye nezinqubo zokulawula ikhwalithi ezinobuhlakani ezidingekayo ukuze kwenziwe amakhebuli avaleleke nge-PVC ukuze asetshenziswe kufika ku-6KV kanye nezintambo ezivale izintambo ze-XLPE/EPR ukuze zisetshenziswe kuma-voltage afika ku-35 KV. .Izinto ezisetshenziswayo zonke zigcinwa ezimeni ezilawulwa ukuhlanzeka kuyo yonke inqubo yokukhiqiza ukuze kuqinisekiswe ukufana okuphelele kwezinto zokufakelwa eziqediwe.

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.
