Iindidi kunye noKhetho lweeCable zaseLwandle

Intambo yolwandle, eyaziwa ngokuba yintambo yamandla olwandle, luhlobo lwengcingo kunye nentambo esetyenziselwa amandla, ukukhanya kunye nokulawula ngokubanzi iinqanawa ezahlukeneyo kunye namaqonga e-oyile e-offshore emilanjeni naselwandle.
Isicelo esiphambili: Isetyenziselwa amandla, ukukhanya kunye nokulawulwa ngokubanzi kweenqanawa ezahlukeneyo kwimilambo kunye nolwandle, iiplatifomu zeoli ye-offshore kunye nezinye izakhiwo zamanzi.Umgangatho wesigqeba ngumgangatho olawulayo wentambo yamandla olwandle: IEC60092-350 IEC60092-353 okanye GB9331-88.
Iiparamitha eziphambili zentambo yamandla olwandle ziquka imodeli, ukucaciswa, inombolo, iimpawu zokutsha, umbane olinganisiweyo, ubushushu, indawo yecandelo eliqhelekileyo, njl.

Iintambo zaselwandlezinokwahlulwa ngokwezi ndidi zilandelayo ngokwezicelo zazo:
1. Iintambo zokukhanyisa kunye neesekethe zamandla.
2. Iintambo zolawulo kunye neelophu zonxibelelwano.
3. Ikhebula yelophu yefowuni.
4. Iintambo zeebhodi zokuhambisa.
5. Iintambo zezixhobo eziphathwayo.
6. Iintambo zocingo lwangaphakathi lwezixhobo zokulawula.
7. Iintambo zezinye izixhobo ezikhethekileyo.

Amanyathelo kunye nemigaqo yokukhetha intambo:
Amanyathelo okukhetha kunye nemigaqo yeentambo kwindlela yamandla enqanawe yile ilandelayo:
1. Khetha imodeli yekhebula efanelekileyo ngokwenjongo, indawo yokubeka kunye neemeko zokusebenza kwekhebula.
2. Khetha icandelo lekhebula elifanelekileyo ngokwenkqubo yokusebenza kwezixhobo, uhlobo lonikezelo lwamandla, undoqo wentambo kunye nomthwalo wangoku.
3. Ngokweziphumo zokubala zesistim yesekethe emfutshane yangoku, nokuba umthamo omfutshane wesekethe yeqhekeza lentambo uyahlangabezana neemfuno.
4. Lungisa umthamo olinganisiweyo wokuthwala ikhebula ngokuhambelana nobushushu be-ambient, uze ugwebe ukuba umbane ovumelekileyo wentambo mkhulu kunomthwalo wangoku.
5. Ngokwemeko yokulungiswa kokubeka i-bundle, umthamo olinganisiweyo wangoku wokuthwala ikhebula ulungiswa, kwaye emva koko kugwetywa ukuba i-current evumelekileyo yekhebula inkulu kunomthwalo wangoku.
6. Khangela ukuhla kwamandla ombane kwaye ugwebe ukuba i-voltage drop line ingaphantsi kwexabiso elichaziweyo.
7. Gweba ukuba intambo ilungelelaniswe nesixhobo sokukhusela ngokwexabiso lokumisela isixhobo sokukhusela;Kwimeko yokungahambelani, gweba ukuba isixhobo esifanelekileyo sokukhusela okanye ixabiso lokumisela lingatshintshwa;kungenjalo, khetha indawo yomthwalo wentambo efanelekileyo kwakhona.

Kukho iintlobo ezininziiintambo zaselwandle, ngoko kufuneka sinikele ingqalelo kwiintambo ezihambelanayo xa sizikhetha, ngaphandle koko kulula ukubangela ingozi enkulu.Xa ukhetha iintambo, qaphela le migaqo ilandelayo: ngokusetyenziswa, oku ngokuqhelekileyo kusetyenziselwa ukwahlula amandla, ukukhanya kunye nonxibelelwano lwerediyo;Xa ukhetha ngokwendawo yokubeka, izinto zokusingqongileyo kufuneka ziqwalaselwe, njengokoma kunye nomswakama womoya, ubushushu obuphezulu kunye obuphantsi kunye neemfuno zokukhusela;Xa ukhetha ngokweemeko zokusebenza, kuyimfuneko ukuqwalasela iimfuno ezininzi njengendawo, inani lemibhobho ukuba ifakwe kwi-threaded kunye nokuba ingaba ingasuswa.
