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.
