Isicelo

Amandla avame ukulethwa enhlokweni yesevisi yomsebenzisi, lapho kuxhunywa endaweni yokungena yesevisi, kusetshenziswa intambo yasemoyeni engu-25kV.
Izosetshenziswa namazinga okushisa ekhondatha angabi ngaphezu kuka-75°C kumakhondaktha afakwe i-polyethyl kanye no-90°C kumakhondaktha axhumene ku-600V noma esigabeni esingaphansi kuya esigabeni.

Ezokwakha

Ikhebula elilodwa elinomqhubi we-AAAC, isihlangu esinwetshiwe esinezendlalelo ezi-3 kanye nesistimu yokumboza, ehlanganisa isivikelo somqhubi we-thermoplastic esikhishiwe, kanye nesembozo sezendlalelo ezi-2.
Isendlalelo esingaphakathi siyi-polyethylene ephansi, emaphakathi noma ephezulu (LDPE, MDPE noma i-HDPE), kuyilapho ungqimba lwangaphandle lumelana namathrekhi i-polyethylene ephakathi nendawo noma ephezulu (TK-MDPE noma i-TK-HDPE).
Zonke izendlalelo zihlanganiswe ndawonye.

Umqhubi:
I-AAAC

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

Isembozo 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.
