ASTM 35kV Aerial Tree Wire Power Line ACSR 3-layer Track-resistant XLPE
THABELLA LITŠOANTŠISO TSA MOKHATLO
Kakaretso
35kV Aerial Overhead Power Line Cable (terata ea sefate le thapo ea spacer) ACSR (compact) 3-layer-resistant PE e sebelisoa holim'a mohala oa sefate kapa oa spacer cable, e entsoeng, ea lekoa le ho tšoauoa ho latela ICEA S-121-733, the maemo a Sefate Wire le Messenger Supported Spacer Cable.
Sistimi ena ea 3-layer e na le thebe ea conductor (layer #1), e lateloe ke sekoaelo sa 2-layer (layers #2 le #3).
Kopo
Aerial Overhead Power Line Cable (terata ea sefate le thapo ea spacer) e reretsoe ho sebelisoa lits'ebetsong tsa kabo ea mantlha le ea bobeli e lekantsoeng 35 kV (ka lebitso) ka tloaelo ho thibela liphoso tse bakoang ke ho kopana kapa moo sebaka se lekanyelitsoeng.
Sistimi e hanyetsanang le pina e 3 e thibela li-circuits le li-flashovers tabeng ea ho kopana le lifate kapa liphoofolo tse hlaha.Ha e kentsoe ka nepo, sistimi ena e sebetsa hantle ho thibela ho tima ha sistimi, ho senyeha kapa ho cha ka lebaka la ho oa ha lifate kapa makala.
Mohala oa Sefate
Ha e sebelisoa tsamaisong ea matla a terata ea sefate, e kenngoa ka mokhoa o bataletseng, ka mokhoa o ts'oanang le ho arohana ho li-insulators joalo ka li-conductors tse se nang letho kapa tse koahetsoeng.Li-conductor tse ikemetseng, tse kang ACSR, li tloaelehile mofuteng ona oa ho kenya.
Spacer Cable
Ha e sebelisoa ka har'a sesebelisoa sa motlakase sa spacer, e kenngoa ka sebaka se ts'oanang sa daemane se bolokiloeng ke lisebelisoa tsa spacer.Kopano ea spacer le cable li tšehetsoa ke lenģosa le se nang letho, joalo ka tšepe e se nang letho ea aluminium, ACSR, OPGW, kapa terata ea galvanized steel.
Likopano tsa lithapo tsa spacer li nka sebaka se fokolang, tse hlokang tsela e moqotetsane kapa tsela.
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 thermoset e extruded, le sekoaelo sa 2-layer.
Lera le ka hare le koahelang ke polyethylene e kopantsoeng (XLPE), ha lesela le ka ntle ke polyethylene e hanyetsanang le pina (TK-XLPE).
Likarolo tsohle li kopantsoe hammoho.
Mokhanni:
AAC (1350-H19, compact 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:
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.
