Kopo

E sebelisoa khafetsa libakeng tse merung, thapo ena ea 15 kV air bundle conductor e ka sebelisoa bakeng sa lithapo tsa phetisetso ea mantlha kapa ea bobeli.Mohala o sirelelitsoe ke sekheo sa polyethylene se nang le sekhahla se phahameng (se thata) kapa se senyenyane (se feto-fetohang) ho tloha makaleng a oelang, lehloa kapa leqhoa.
Ho koahela meru e tebileng kapa libaka tsa bolulo tse ka thōko, ho tla sebelisoa likhoele tsa lifate.Ho boloka mela e hlakile ntle le litšitiso, ho koahela sebaka se joalo ka li-conductors tse tloaelehileng ho hloka tlhokomelo e ngata ea kamehla.Likoahelo tse sireletsang li ka fokotsa tlhokomelo ho isa tekanyong e kholo ha melapo e holimo e hlokahala libakeng tse nang le lifate.Hape ho sireletsehileng bakeng sa liphoofolo tse hlaha ke likoahelo tse entsoeng ka polyethylene.

Kaho

Ho latela boholo ba mokhanni, li-conductor tsa terata ea sefate (AAAC) li ka hatelloa kapa li kopane 'me li tla ka AAC kapa ACSR.Ho lumellana le lits'ebetso tse fapaneng, li-conductors li ka tšeloa ka polyethylene e hananang le pina e phahameng haholo (HDTRPE) kapa polyethylene e hanyetsanang le pina (XLPE).

-Mokhanni:
AAAC (6201-T81, concentric stranded).

-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:
Sekoaelo sa polyethylene ea 2-layer e tlase, e bohareng kapa e phahameng haholo (LDPE, MDPE kapa HDPE), moo lesela le ka ntle le hananang le pina (TK-MDPE kapa TK-HDPE).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.
