I-IEC/BS Standard 3.8-6.6kV-XLPE Ikhebula Lamandla Lamandla Ephakathi Le-MV Elingafakiwe
I-3.8/6.6kV isilinganiso sikagesi esivame ukuhlotshaniswa nezindinganiso zaseBrithani, ikakhulukazi izici ezicacisiwe ze-BS6622 ne-BS7835, lapho izinhlelo zokusebenza zingazuza ekuvikelweni kwemishini okuhlinzekwa yizintambo zazo ze-aluminium noma izikhali zensimbi yensimbi (kuye ngokuthi umgogodla owodwa noma ukumiswa okuthathu okuyinhloko).Izintambo ezinjalo zingakufanelekela kahle ukufakwa okungaguquki futhi zinikeze amandla kuzinto eziqinile eziqinile njengoba ukwakhiwa kwazo okuqinile kukhawulela irediyasi egobile.
Ifanele amanethiwekhi wamandla njengeziteshi zikagesi.Ukufakwa emiseleni, ngaphansi nangaphandle.
Sicela uqaphele: Igobolondo langaphandle elibomvu lingaba lula ukufiphala lapho lichayeke emisebeni ye-UV.

I-IEC/BS Standard 6-10kV-XLPE Ikhebula Lamandla Lamandla Ephakathi Le-MV Engafakiwe
Ifanele amanethiwekhi wamandla njengeziteshi zikagesi.Ukufakwa emiseleni, ngaphansi nangaphandle.
I-aluminium wire armor (AWA) yezintambo eziwumgogodla owodwa kanye nensimbi yensimbi yesikhali (i-SWA) yamakhebuli amaningi ahlinzeka ngokuvikelwa komshini okuqinile okwenza lezi zintambo ezingu-11kV zifanelekele ukungcwatshwa ngokuqondile emhlabathini.Lawa makhebula kagesi e-armored MV mains avame ukunikezwa amakhondaktha ethusi kodwa ayatholakala namakhondatha e-aluminium uma ecelwa ngezinga elifanayo.Amakhondaktha ethusi aminyene (Ikilasi 2) kuyilapho amakhondatha e-aluminium ethobelana nendinganiso esebenzisa kokubili ukwakhiwa okuminyene nokuqinile (Ikilasi 1).

I-IEC/BS Standard 8.7-15kV-XLPE Ikhebula Lamandla Lamandla Ephakathi Le-MV Elingafakiwe
I-15kV ivolumu evame ukucaciswa izintambo zemishini, okuhlanganisa izintambo eziqinile zemishini yezimayini, ekhiqizwa ngokuhambisana ne-IEC 60502-2, kodwa ibuye ihlotshaniswe nezintambo ezijwayelekile zezikhali zaseBrithani.Nakuba izintambo zezimayini zingagqunywa kuRubha eqinile ukuze zikwazi ukumelana nokuhuzuka, ikakhulukazi uma zilandela ngemuva, izintambo ezijwayelekile ze-BS6622 kanye ne-BS7835 esikhundleni salokho zimbozwe ngezinto ze-PVC noma ze-LSZH, ngokuvikelwa kwemishini okuhlinzekwa ungqimba lwensimbi yensimbi yokuhlomisa.

I-IEC/BS Standard 12.7-22kV-XLPE Ikhebula Lamandla Lamandla Ephakathi Le-MV Elingafakiwe
Ifanele amanethiwekhi wamandla njengeziteshi zikagesi.Ukufakwa emiseleni, ngaphansi nangaphandle.
Amakhebuli enziwe ku-BS6622 kanye ne-BS7835 ngokuvamile ahlinzekwa ngamakhondaktha e-Copper ane-Class 2 yokuxhuma okuqinile.Izintambo eziwumgogodla owodwa zine-aluminium wire armor (AWA) ukuze kuvinjwe amandla akhona endaweni yezempi, kuyilapho amakhebuli amaningi ane-steel wire armor (SWA) ehlinzeka ngokuvikelwa komshini.Lezi izintambo eziyindilinga ezihlinzeka ngokufaka okungaphezu kuka-90%.
Sicela uqaphele: Igobolondo langaphandle elibomvu lingaba lula ukufiphala lapho lichayeke emisebeni ye-UV.

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.

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.
