Okusinziira ku ddaala lya vvulovumenti, zisobola okugabanyizibwamu waya z’amasannyalaze eza vvulovumenti eya wakati n’eya wansi (35 kV n’okudda wansi), waya za vvulovumenti eya waggulu (okusukka kV 110), waya za vvulovumenti ey’amaanyi ennyo (275-800 kV), ne waya za vvulovumenti eya waggulu ennyo (1000 kV n’okudda waggulu). Ekirala, zisobola okugabanyizibwamu waya za AC ne DC okusinziira ku kasasiro.
Okusinziira ku Insulation Material
. Tezirina bulabe, zeesigika, ziwangaala nnyo era tezigula ssente nnyingi. Ekizibu kyazo ekikulu kwe kukoma ku buwanvu bw’okussaako. Okukola enkola y’okuziyiza empapula ezifukiddwa nga tezitonnya-kigonjodde ekkomo lino ery’obugulumivu, okusobozesa waya eziziyiza empapula ezifukiddwa mu mafuta-okugenda mu maaso n’okuzikozesa ennyo.
2. Waya z’amasannyalaze eziziyiza obuveera-: Waya z’amasannyalaze ezirina oluwuzi oluziyiza obuveera olufulumiziddwa. Ebiveera ebisinga okukozesebwa mulimu polyvinyl chloride, polyethylene, ne cross-linked polyethylene. Waya z’obuveera zirina enzimba ennyangu, nnyangu okukola n’okukola, tezizitowa, era nnyangu okuziteeka n’okuziteeka awatali bukwakkulizo ku buwanvu bw’okuziteeka. N’olwekyo, zikozesebwa nnyo ku waya za vvulovumenti eya wakati n’eya wansi era zigenda mu maaso n’okukyusa waya z’empapula ezifukiddwamu amafuta agawunya-. Ekizibu kyayo ekisinga obunene ye dendrite breakdown phenomenon, ekikoma ku nkozesa yaayo ku voltages eza waggulu.
3. Rubber-insulated power cable: Layer insulation ekolebwa mu rubber nga egattibwa wamu n’ebirungo eby’enjawulo ebigatta, ebitabulwa bulungi, ne bifulumizibwa ku conductive core, n’oluvannyuma ebbugumu-vulcanized. Kigonvu ate nga kigonvu, ekigifuula esaanira okuteeka mu bifo ebitambula ennyo n’obuwanvu obutono obw’okubeebalama.
Ebirungo bya kapiira ebya bulijjo ebikozesebwa mu kuziyiza omuliro mulimu emipiira egy’obutonde-styrene-butadiene rubber blends, ethylene propylene rubber, ne butyl rubber.
Okugabanya okusinziira ku ddaala lya vvulovumenti:
1. Low-voltage cable: Esaanira okuteekebwa okutambula ku layini z’okutambuza n’okusaasaanya AC 50Hz nga zirina vvulovumenti egereddwa eya 3kV n’okudda wansi, okutambuza amaanyi.
.
3. Waya za vvulovumenti eya waggulu-: (okutwalira awamu 110kV n’okudda waggulu): waya za PE ne waya ezisalasala- eziyungiddwa mu polyethylene eziziyiza, n’ebirala.
