Kopo

ASTM 25kV SAC Cable System e sebelisoa bakeng sa kabo ea mantlha kapa ea bobeli e nang le sebaka se lekanyelitsoeng se fumanehang.
SAC Cable ena e loketse li-voltages tse fihlang ho 25,000 volts.
Mohala ona oa sefate o sirelelitsoe ho thibela lipotoloho tse khutšoanyane tse tobileng le li-flashovers tsa nakoana haeba ho hloa lifate kapa lintho tse ling li kopana le li-conductor tse haufi joalo.

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:
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.
