5. Sebopeho sa cable
Conductor e entsoe ka koporo ea boleng bo holimo e entsoeng ka makotikoti.Mofuta ona oa mokhanni o na le phello e ntle haholo ea anti-corrosion.Sebopeho sa conductor se arotsoe ka li-conductor tse tiileng, li-conductor tse tsielehileng le li-conductor tse bonolo.
Insulation e sebelisa extruded insulation.Mokhoa ona oa extrusion o ka fokotsa khase pakeng tsa conductor le sekontiri ho thibela ho kena ha litšila tse kang mouoane oa metsi.
Khoutu ea mebala ka kakaretso e khetholloa ka 'mala.Mebala e ka khethoa le ho sebetsoa ho latela litlhoko tsa sebaka sa ho kenya habonolo.
Sheath/liner (Jacket) e ka hare ke thepa e se nang halogen e se nang mosi o tlase e nang le lelakabe le phahameng la ho lieha.Lisebelisoa ha li na halogen.
Lera la lihlomo (Lihlomo) ke mofuta o lohiloeng.Mofuta ona oa lihlomo o na le maemo a feto-fetohang 'me o loketse ho beha cable.Lisebelisoa tsa lihlomo tse lohiloeng li kenyelletsa terata ea koporo e kentsoeng le terata ea masenke, tseo ka bobeli li nang le phello e ntle ea ho thibela ho bola.
Thepa e ka ntle ea sheath (Sheath) e boetse ke lisebelisoa tse se nang mosi o tlase oa halogen.Sena ha se hlahise khase e chefo ha se chesa 'me se hlahisa mosi o monyenyane.E sebelisoa haholo libakeng tse tletseng batho.
Boitsebiso ba cable bo ka hatisoa ho latela litlhoko tsa sebele.
