15kV Aerial Electrical Cable bakeng sa mesebetsi ea mantlha le ea bobeli moo sebaka se lekanyelitsoeng kapa se loketseng ho ea tseleng.E kentsoe e le mokhanni ea sa tsitsang;
Leha ho le joalo, sekoahelo se sebetsa khahlanong le li-circuits tse khutšoanyane tse tobileng le li-flashovers tsa nakoana ha makala a lifate kapa lintho tse ling li ama li-conductor tse haufi joalo.Sephetho sa sephetho sa ho koala se fokotsa sebaka le lisebelisoa tse hlokahalang bakeng sa ho kenya mohala;haholo-holo dibakeng tse petetsaneng tse kang alleyways kapa diphaseje tse tshesane.

Kaho

Cable e le 'ngoe e nang le mokhanni oa ACSR, thebe e fetisitsoeng ka 3-layer le sistimi e koahelang, e nang le thebe ea conductor ea thermoplastic e extruded, le sekoaelo sa 2-layer.Lera le ka hare le koahelang ke polyethylene e tlaase-, e bohareng kapa e phahameng-density (LDPE, MDPE kapa HDPE), ha lesela le ka ntle ke polyethylene e hanyetsanang le tsela e mahareng- kapa e phahameng-tlaase (TK-MDPE kapa TK-HDPE).Likarolo tsohle li kopantsoe hammoho.

-Mokhanni:
ACSR (e tsitsitseng haholo).

-Conductor Shield:
Thebe e ekelitsoeng ea thermoplastic e hlobolisoang ho tsoa ho conductor mme e tlameletsoe ho sekhurumetso.

-Sekoahelo sa ka hare le sa ka ntle:
2-layer crosslinked polyethylene e kwahelang (XLPE), moo lera le ka ntle le hananang le pina (TK-XLPE).Likarolo tsohle li kopantsoe hammoho.Karolo e ka ntle e lokela ho ba e ntšo kapa e bohlooho, e hanyetsane le khanya ea letsatsi, 'me e hanyetse pina.
