Isicelo

Isetshenziswa kakhulu ezindaweni ezinamahlathi, le khebula yekhondatha yenqwaba ye-aerial engu-15 kV ingase isetshenziselwe izintambo zokudlulisela ezihamba phezulu noma zesibili.Intambo ivikelwe igobolondo le-polyethylene elinokuminyana okuphezulu (okuqinile) noma elinokuminyana okuphansi (eliguquguqukayo) elisuka emagatsheni awayo, iqhwa, noma iqhwa.
Ukuvala ububanzi behlathi elijulile noma izindawo zokuhlala ezicashile, kuzosetshenziswa izintambo zezihlahla.Ukugcina imigqa icacile ekuvinjweni, ukumboza indawo enjalo ngama-conductor ajwayelekile kudinga ukunakekelwa okuningi okuqhubekayo.Izembozo ezivikelayo zinganciphisa ukunakekelwa ngokwezinga elikhulu lapho imigqa ephezulu idingeka ezindaweni ezinezinkuni.Okunye okuphephe kakhulu ezilwaneni zasendle izembozo ezenziwe nge-polyethylene.

Ezokwakha

Ngokosayizi wekhondatha, amakhondatha wentambo yesihlahla ama-concentrically stranded (AAAC) acindezelwe noma ahlangene futhi angena nge-AAC noma i-ACSR.Ukuze ivumelane nezinhlelo zokusebenza ezihlukene, amakhondakta angafakwa inhlabathi nge-polyethylene engamelana nethrekhi ephezulu-ukuminyana (i-HDTRPE) noma i-polyethylene engavimbeli ithrekhi (XLPE).

-Umqhubi:
I-AAAC (6201-T81, i-concentric stranded).

-Conductor Shield:
Isihlangu esinwetshiwe se-semiconducting thermoplastic esikhumula mahhala ku-conductor futhi sihlanganiswe nesembozo.

-Isimbozo sangaphakathi nangaphandle:
Isembozo se-polyethylene enesendlalelo esi-2 esiphansi, esimaphakathi noma esiphezulu (LDPE, MDPE noma i-HDPE), lapho ungqimba lwangaphandle lumelana namathrekhi (TK-MDPE noma i-TK-HDPE).Zonke izendlalelo zihlanganiswe ndawonye.Ungqimba lwangaphandle luzoba mnyama noma lube mpunga, lumelane nokukhanya kwelanga futhi lukwazi ukumelana namathrekhi.
