Isicelo

I-15kV Aerial Electrical Cable yemisebenzi eyinhloko neyesibili lapho isikhala silinganiselwe noma sidingeka ilungelo lendlela.Kufakwe umqhubi ongafakwanga mshini;
Kodwa-ke, isembozo sisebenza ngempumelelo ngokumelene namasekhethi amafushane aqondile kanye nokugqama kwesikhashana uma amagatsha esihlahla noma ezinye izinto zithinta amakhondatha aseduze kangako.Umphumela wokucushwa kokuvalwa kunciphisa isikhala nehadiwe edingekayo ekufakweni kolayini;iwusizo ikakhulukazi ezindaweni eziminyene njengemihubhe noma amaphasishi amancane.

Ezokwakha

Ikhebula elilodwa elinomqhubi we-ACSR, isihlangu esinwetshiwe sezendlalelo 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-ACSR (i-concentric stranded).

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

-Isimbozo 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.
