Kopo

15kV Aerial Power Cable (terata ea sefate le thapo ea spacer) AAC (compact) 3-layer track-resistant PE e reretsoe ho sebelisoa litsing tsa kabo ea mantlha le ea bobeli e fuoeng 15 kV (nominal) hangata ho thibela liphoso tse bakoang ke ho kopana kapa moo sebaka se leng teng. lekanyetsoa.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 AAC, thebe e pharalletseng ea 3-layer le sistimi e koahelang, e nang le thebe e kentsoeng ea thermoplastic conductor, 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:
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:
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.
