Ikhebula Lamandla Elijwayelekile Le-IEC/BS Eliyi-19-33kV-XLPE Elifakwe I-MV Ephakathi Eliyi-insulated
Izintambo zikagesi ze-MV ezifakwe i-XLPE ezijwayelekile ze-IEC/BS zihambisana nemininingwane ye-International Electrotechnical Commission (IEC) kanye ne-British Standards (BS).
I-IEC 60502-2: Icacisa ukwakhiwa, ubukhulu kanye nokuhlolwa kwezintambo zikagesi ezifakwe ugesi ezifika ku-30 kV.
I-BS 6622: Isebenza kumakhebula avikelwe nge-thermoset afakwe i-insulated kuma-voltage angu-19/33 kV. -
Ikhebula Lamandla le-MV Elihlanganisiwe le-IEC BS elijwayelekile elingu-12-20kV-XLPE elifakwe i-PVC
Ifanele amanethiwekhi kagesi njengeziteshi zikagesi. Ingafakwa emipayipini, ngaphansi komhlaba nangaphandle.
Kunezinhlobo eziningi zokushintshashintsha ekwakheni, ezindinganisweni kanye nezinto ezisetshenziswayo – ukucacisa ikhebula le-MV elifanele lephrojekthi kuyindaba yokulinganisela izidingo zokusebenza, izidingo zokufakwa, kanye nezinselele zemvelo, bese kuqinisekiswa ukuhambisana kwekhebula, imboni, kanye nomthetho. Njengoba i-International Electrotechnical Commission (IEC) ichaza izintambo ze-Medium Voltage njengezinesilinganiso se-voltage esingaphezu kwe-1kV kufika ku-100kV, lokho kuyibanga elibanzi le-voltage okufanele licatshangelwe. Kuvamile ukucabanga njengoba senza maqondana ne-3.3kV kuya ku-35kV, ngaphambi kokuba ibe yi-voltage ephezulu. Singasekela imininingwane yekhebula kuzo zonke i-voltage.

Ikhebula Lamandla Elijwayelekile Le-IEC/BS Eliyi-3.8-6.6kV-XLPE Elifakwe I-MV Ephakathi Eliyi-Insulated
Izintambo zikagesi ze-IEC/BS 3.8/6.6kV ze-XLPE-insulated medium-voltage (MV) ziyizintambo ezijwayelekile ezenzelwe ngqo amanethiwekhi okusabalalisa.
Lezi zintambo zakhiwe ngokuhambisana ne-International Electrotechnical Commission (IEC) kanye ne-British Standards (BS).
I-3.8/6.6kV iyisilinganiso se-voltage esivame ukuhlotshaniswa nezindinganiso zaseBrithani, ikakhulukazi zombili izincazelo ze-BS6622 kanye ne-BS7835, lapho izinhlelo zokusebenza zingazuza ekuvikelweni kwemishini okunikezwa yi-aluminium wire noma i-steel wire armour (kuye ngokuthi i-single core noma i-three core configurations). Izintambo ezinjalo zingafaneleka kahle ekufakweni okuhleliwe futhi zinikeze amandla emishinini eqinile eqinile njengoba ukwakhiwa kwazo okuqinile kukhawulela i-radius egobile. -
Ikhebula Lamandla Elijwayelekile Le-IEC/BS Eliyi-6.35-11kV-XLPE Elifakwe I-MV Ephakathi Eliyi-Insulated
Izintambo zikagesi ze-XLPE ezijwayelekile ze-IEC/BS 6.35-11kV ezifakwe i-XLPE zifanele ukusetshenziswa kumanethiwekhi okusabalalisa amandla e-voltage aphakathi nendawo.
Ikhebula likagesi elinama-conductor ethusi, isikrini somqhubi oqhuba kancane, ukufakelwa kwe-XLPE, isikrini sokufakelwa kancane, isikrini sensimbi se-copper tape senhliziyo ngayinye, imibhede ye-PVC, i-galvanized steel wire armor (SWA) kanye ne-PVC outer sheath. Kumanethiwekhi wamandla lapho kulindeleke khona ukucindezeleka kwemishini. Kufaneleka ukufakwa ngaphansi komhlaba noma emapayipini. -
Ikhebula Lamandla Elijwayelekile Le-IEC/BS Eliyi-6-10kV-XLPE Elifakwe I-MV Ephakathi Eliyi-insulated
Izintambo zikagesi ze-IEC/BS 6-10kV ze-XLPE-insulated medium-voltage (MV) zihambisana nezindinganiso ezifana ne-IEC 60502-2 zezintambo ze-XLPE-insulated kanye ne-BS 6622 zezintambo ezivikelwe.
Ama-conductor asebenzisa i-XLPE ukuze afinyelele ekushiseni kukagesi okuhle kakhulu kanye nokushisa. -
Ikhebula Lamandla Elijwayelekile Le-IEC/BS 8.7-15kV-XLPE Elifakwe Ukushisa Le-MV Ephakathi
Izintambo zikagesi ze-XLPE ezifakwe i-XLPE-insulated medium-voltage (MV) zenzelwe ngqo amanethiwekhi okudlulisa amandla nokusabalalisa.
Le ntambo ye-medium-voltage ihambisana nezindinganiso ze-International Electrotechnical Commission (IEC) kanye ne-British Standards (BS).
8.7/15kV, okubonisa ukufaneleka kwezinhlelo ezine-voltage ephezulu yokusebenza engu-15kV. I-15kV iyi-voltage evame ukucaciswa kumakhebula emishini, kufaka phakathi amakhebula emishini yezimayini aqinile, akhiqizwa ngokuhambisana ne-IEC 60502-2, kodwa futhi ahlotshaniswa namakhebula avikelwe ajwayelekile aseBrithani. Ngenkathi amakhebula okumba angafakwa egoqweni lerabha eliqinile ukuze anikeze ukumelana nokuguguleka, ikakhulukazi ekusetshenzisweni kokulandela, amakhebula ajwayelekile e-BS6622 kanye ne-BS7835 afakwe egoqweni ngezinto ze-PVC noma ze-LSZH, ngokuvikelwa komshini okuhlinzekwa ungqimba lwensimbi yokuvikela. -
Ikhebula Lamandla Elijwayelekile Le-IEC/BS Eliyi-12.7-22kV-XLPE Elifakwe I-MV Ephakathi Eliyi-Insulated
Ifanele amanethiwekhi kagesi njengeziteshi zikagesi. Ingafakwa emipayipini, ngaphansi komhlaba nangaphandle.
Izintambo ezenziwe nge-BS6622 kanye ne-BS7835 ngokuvamile zihlinzekwa ngama-conductor e-Copper ane-stranding eqinile ye-Class 2. Izintambo eziyinhloko eyodwa zine-aluminium wire armour (AWA) ukuvimbela ugesi obangelwa yi-induction esivikeloni, kanti izintambo eziyinhloko eziningi zine-steel wire armour (SWA) enikeza ukuvikelwa komshini. Lezi yizintambo eziyindilinga ezihlinzeka ngokumbozwa okungaphezu kuka-90%.
Sicela uqaphele: Isikhumba sangaphandle esibomvu singase sithambekele ekubuneni uma sichayeka emisebeni ye-UV.
