Isicelo

Ikhebula lasemoyeni (intambo yesihlahla kanye nekhebuli yesikhala) ihloselwe ukusetshenziswa ezinhlelweni zokusabalalisa ezihamba phezulu eziyinhloko nelesibili ezilinganiselwe ngo-25 kV (okungenani) ngokuvamile ukuze kuvinjelwe amaphutha ngenxa yokuxhumana noma lapho isikhala silinganiselwe.
Isistimu enezingqimba ezi-3 ezimelana nethrekhi ivimbela ama-short-circuits kanye nama-flashavers esimweni sokuxhumana nezihlahla noma izilwane zasendle.Uma ifakwe ngendlela efanele, lesi simiso sisebenza ngempumelelo ekuvimbeleni ukucisha kwesistimu, ukulimala, noma imililo ngenxa yokuwa kwezihlahla noma amagatsha.

Intambo Yesihlahla

Uma isetshenziswa kusistimu yamandla ezintambo zesihlahla, ifakwa ekucushweni okuyisicaba, ngendlela efanayo kanye nesikhala kuma-insulators njengamakhondaktha angaphezulu angenalutho noma amboziwe.Ama-conductor azisekelayo, afana ne-ACSR, ajwayelekile kulolu hlobo lokufakwa.

Ikhebula le-Spacer

Uma isetshenziswa kusistimu yamandla ekhebula yesikhala, ifakwa ngesikhala esifanayo ekucushweni kwedayimane okugcinwa yi-spacer hardware.Ukuhlanganiswa kwe-spacer nekhebula kusekelwa yisithunywa esingenalutho, njengensimbi engenalutho ye-aluminium, i-ACSR, i-OPGW, noma izintambo zensimbi.
Amakhebula e-Spacer athatha indawo encane, edinga indlela encane yendlela noma iphaseji.

Ukwakha

Ama-conductor axhunywe ngokujulile, i-AAC (1350-H19), icindezelwe noma ihlangene ngokugcwele kuye ngosayizi womqhubi, i-AAAC noma i-ACSR.Itholakala nge-polyethylene emelana nethrekhi ephezulu kakhulu (HDTRPE) noma i-Track-Resistant Crosslinked Polyethylene (XLPE) imboza.Inketho ye-Strand shield iyatholakala njengoba kukhonjisiwe emfanekisweni.
