Thumela I-imeyiliI-SThe aluminium wire armor (AWA) yezintambo eziwumgogodla owodwa kanye nesikhali sensimbi yensimbi (i-SWA) yamakhebula 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).
Amazinga:
BS6622
I-IEC 60502
Izici :
Ikhondaktha: amakhondaktha ethusi ahlanganisiwe ayindilinga ayindilinga nomaumqhubi we-aluminium
I-Insulation: i-cross link polyethylene (XLPE)
Isikrini se-Metallic: isikrini somuntu ngamunye noma sisonke se-copper tape
Isihlukanisi: itheyiphu yethusi enokugqagqana okungu-10%.
Igumbi lokulala: i-polyvinyl chloride (PVC)
Izikhali: I-Steel Wire Armor (SWA), I-Steel Tape Armor (STA), I-Aluminium Wire Armor (AWA), I-Aluminium Tape Armor (ATA)
I-Sheath: I-PVC yangaphandle ye-sheath
Umbala we-Sheath: Obomvu noma Omnyama
Ukwakha :
1.Umqhubi
Ikhondatha yethusi eyindilinga eyindilinga ehambisana ne-BS6360 Class 2.
Isikrini Somqhubi
Inhlanganisela ye-semi-conducting enwetshiwe eboshelwe ku-insulation futhi isetshenziswe ekusebenzeni okufanayo nokufakwa.
2.I-Insulation
I-ployethylene exhunywe i-cross-linked extruded (XLPE) efaneleka ukusebenza ezingeni lokushisa likakhondatha elingu-90°C.
3.Isikrini Sokugquma
Inhlanganisela ye-semi-conducting enwetshiwe isetshenziswa ekusebenzeni okufanayo nokufakwa.Izikrini ezikhumukayo ezibandayo zinikezwa njengezikrini ezijwayelekile kodwa eziboshwe ngokugcwele zinganikezwa uma zicacisiwe.
4.Metallic Screen
Amateyipu ethusi asetshenziswe agqagqene ukuze anikeze indlela yamanje yephutha lomhlaba.
5.Ukubeka
Ama-cores amathathu abekwe nge-polypropylene string fillers ukuze akhe ikhebula eliyindilinga elihlangene, futhi liboshwe ngetheyiphu.
6.Tape Binder
7.Umgodla
I-polyvinyl chloride emnyama enwetshiwe (PVC) noma inhlanganisela ye-Low Smoke Zero Halogen (LSOH) inikezwa njengokujwayelekile.Ezinye izinto zinganikezwa uma zibaluliwe.
8.Izikhali
Isendlalelo esisodwa sezintambo zensimbi eziyindilinga.
9.Oversheath
I-polyvinyl chloride emnyama enwetshiwe (PVC) noma inhlanganisela ye-Low Smoke Zero Halogen (LSOH) inikezwa njengokujwayelekile.Ezinye izinto zinganikezwa uma kucacisiwe isb. i-medium density polyethylene (MDPE).
Idatha kagesi:
Izinga lokushisa eliphezulu lokusebenzisa ikhondatha: 90°C
Izinga lokushisa eliphezulu lokusebenza kwesikrini: 80°C
Izinga lokushisa eliphezulu le-conductor ngesikhathi se-SC: 250°C
Imibandela Yamanje Yezilinganiso:
Izinga lokushisa eliphansi ngu-15°C
Izinga lokushisa le-ambient (umoya) 25°C
Ukujula kokungcwaba 0.8m
Ukumelana nokushisa kwenhlabathi 1.2°C m/W
