Ulwakhiwo olusisiseko lwentambo yamandla luqulathe amacandelo amane: i-wire core (i-conductor), i-insulation layer, i-shielding layer kunye ne-protective layer. I-insulation layer yindlela yokwahlulwa kombane phakathi kwe-wire core kunye nomhlaba kunye nezigaba ezahlukeneyo ze-wire core ukuqinisekisa ukuhanjiswa kwamandla ombane, kwaye yinxalenye ebalulekileyo yesakhiwo sentambo yamandla.
Indima yomaleko wokukhusela:
Umbindi wentambo yi-conductor. Ukuze kuthintelwe umonakalo wezixhobo obangelwa yi-short circuit yeengcingo eziveziweyo kunye nomonakalo kubantu obangelwa ziingcingo ezidlula i-voltage yokhuseleko, kufuneka kongezwe umaleko okhuselayo okhuselayo kwintambo. Ukumelana kombane kwe-conductor yesinyithi kwintambo kuncinci kakhulu, kwaye ukumelana kombane kwe-insulator kuphezulu kakhulu. Isizathu sokuba i-insulator ingagqunywa kukuba: iitshaja ezilungileyo nezingalunganga kwiimolekyuli ze-insulator zibotshelelwe ngokuqinileyo, amasuntswana atshajiweyo anokuhamba ngokukhululekileyo ambalwa kakhulu, kwaye ukumelana kukhulu kakhulu, ngoko ke ngokubanzi, i-macro current eyenziwe yintshukumo yetshaja ekhululekileyo phantsi kwesenzo sentsimi yombane yangaphandle inokungahoywa, kwaye ithathwa njengento engeyiyo i-conductive. Kwi-insulators, kukho i-voltage yokuqhekeka enika ii-electron amandla aneleyo okuzivuselela. Nje ukuba i-voltage yokuqhekeka idlule, izinto azisayigqunywa.
Iyintoni impembelelo yobukhulu bokugquma obungenamfaneleko kwintambo?
Nciphisa ubomi benkonzo yeemveliso zentambo kunye neentambo, ukuba inqaku elincinci le-cable sheath alihlangabezani neemfuno, emva kokusebenza ixesha elide, ingakumbi kwindawo efihliweyo ngqo, engaphantsi kwamanzi, evulekileyo okanye ebolileyo, ngenxa yokubola kwexesha elide kwesixhobo sangaphandle, inqanaba lokufakelwa kunye nenqanaba loomatshini lenqaku elincinci le-sheath liya kuncipha. Uvavanyo lwesiqhelo lwe-sheath okanye ukungaphumeleli komgca wokumisa, inqaku elincinci linokwaphulwa, isiphumo sokukhusela se-cable sheath siya kulahleka. Ukongeza, ukusetyenziswa kwangaphakathi akunakutyeshelwa, amandla e-wire kunye neentambo ixesha elide aya kuvelisa ubushushu obuninzi, kuya kunciphisa ubomi benkonzo yentambo kunye neentambo. Ukuba umgangatho awukho kumgangatho ofanelekileyo, kuya kubangela umlilo kunye nezinye iingozi zokhuseleko.
Ukwandisa ubunzima benkqubo yokubeka, kwinkqubo yokubeka kufuneka ucinge ngokushiya isithuba, ukuze unciphise ubushushu obuveliswa emva kwamandla entambo kunye neentambo, ubukhulu beshelufu bukhulu kakhulu buya kwandisa ubunzima bokubeka, ngoko ke ubukhulu beshelufu bufuna ukuthotyelwa ngokungqongqo kwemigangatho efanelekileyo, kungenjalo abunakudlala indima ekukhuseleni ucingo kunye neentambo. Enye yeempawu zomgangatho wemveliso ibonakala kumgangatho wembonakalo yemveliso. Nokuba yintambo yamandla okanye ucingo olulula lwelaphu, umgangatho womaleko wokufakelwa kufuneka uqwalaselwe kwimveliso, kwaye kufuneka ulawulwe ngokungqongqo kwaye uvavanywe.
Mhlawumbi abantu abaninzi baya kuba namathandabuzo, ekubeni indima yomaleko wokufaka ubushushu inkulu kakhulu, umphezulu wentambo yokukhanyisa kunye nentambo ye-voltage ephantsi zigqunywe ngumaleko weplastiki okanye werabha yokufakela ubushushu, kwaye intambo ye-voltage ephezulu ebaleni ayigqunywanga ngufakelo.
Kuba xa i-voltage iphezulu kakhulu, ezinye izinto eziqalayo ukuvala ubushushu, ezifana nerabha, iplastiki, umthi owomileyo, njl.njl., nazo ziya kuba zii-conductors, kwaye aziyi kuba nefuthe lokuvala ubushushu. Ukugquma ubushushu kwiintambo ze-voltage ephezulu kukuchitha imali kunye nezixhobo. Umphezulu wocingo lwe-voltage ephezulu awugqunywanga yi-insulation, kwaye ukuba uxhonywe kwi-high tower, unokuvuza umbane ngenxa yokudibana ne-tower. Ukuze kuthintelwe le nto, ucingo lwe-voltage ephezulu luhlala luxhonywe phantsi koluhlu olude lweebhotile ze-porcelain ezigqunywe kakuhle, ukuze ucingo lwe-voltage ephezulu lugqunywe kwi-tower. Ukongeza, xa ufaka iintambo ze-voltage ephezulu, musa ukuzirhuqa emhlabeni. Ngaphandle koko, ngenxa yokungqubana phakathi kocingo nomhlaba, umaleko we-insulation ogudileyo ekuqaleni uyonakala, kwaye kukho ii-burrs ezininzi, eziya kukhupha ukukhupha, okubangela ukuvuza.
Umaleko wokwambathisa intambo umiselwe ngokweemfuno zentambo. Kwinkqubo yemveliso, abavelisi kufuneka balawule ubukhulu bokwambathisa ngokuhambelana nemigangatho yenkqubo, bafezekise ulawulo olupheleleyo lwenkqubo, kwaye baqinisekise umgangatho wentambo kunye nentambo.
