Isicelo

Ukuze ugweme amaphutha okuxhumana noma ezimeni lapho isikhala siphezulu kakhulu, Ikhebula Le-Aerial ye-ASTM 25kV (intambo yesihlahla nekhebula yesikhala) iklanyelwe ukusetshenziswa ezinhlelweni zokusabalalisa ezihamba phezulu eziyinhloko nelesibili ezilinganiselwe ku-25 kV (igama elivamile).
Uma kwenzeka ukuthintana nezihlahla noma ezinye izilwane zasendle, ukwakheka kwethrekhi okunezingqimba ezi-3 kuqeda imijikelezo emifushane nama-flashavers.Lolu hlelo lungamisa ngempumelelo ukwehluleka kwesistimu, ukulimala, noma imililo ebangelwa ukuwa kwezihlahla noma amagatsha lapho lubekwe kahle.

Ukwakha

Ikhebula le-Aerial Spacer eline-conductor eyenziwe nge-aluminium ngokuphelele, isihlangu esinezendlalelo ezi-3 esikhishiwe kanye nesistimu yokumboza eyenziwe ngesembozo sezendlalelo ezi-2 kanye nesihlangu sekhondatha se-semiconducting semiconducting esikhishiwe se-thermoset.
I-Crosslinked polyethylene yenza ungqimba lwangaphakathi lwesembozo, futhi i-polyethylene enqamulayo emelana nethrekhi yenza ungqimba lwangaphandle.
Isendlalelo ngasinye sihlanganiswe nesibopho.

Umqhubi:
I-AAC (1350-H19, iminyene).

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

Isembozo sangaphakathi nangaphandle:
Isembozo se-polyethylene engu-2-layer crosslinked (XLPE), lapho ungqimba lwangaphandle lumelana namathrekhi (TK-XLPE).Zonke izendlalelo zihlanganiswe ndawonye.Ungqimba lwangaphandle luzoba mnyama noma lube mpunga, lumelane nokukhanya kwelanga futhi lukwazi ukumelana namathrekhi.

Amazinga

Ngokuhambisana nemininingwane ebekwe yi-American Society for Testing and Materials:
Izingxenye zekhondatha ye-aluminium 1350-H19 zalo mkhiqizo zihlangabezana noma zeqa izindinganiso ze-B230 zezinto ezishiwo.
Izingxenye zekhondakta ziphinde zihlangabezane nezinga le-B231 lezintambo ze-aluminium ezigxilile-lay-stranded 1350-H19.
I-steel reinforced aluminium concentric-lay-stranded (ACSR) ihlangabezana namazinga e-B232.
Umgogodla wensimbi enama-zinc-coated ukuze uqiniswe uhlangabezana nezindinganiso ze-ASTM B498.
