Iintambo zamandla ombane aphezulu kunye neentambo zombane ophantsi zinomohluko ocacileyo wolwakhiwo, okuchaphazela ukusebenza kwazo kunye nokusetyenziswa kwazo. Ukwakhiwa kwangaphakathi kwezi ntambo kubonisa ukungafani okuphambili:
Ulwakhiwo lweCable yoMbane oPhezulu:
1. Umqhubi
2. I-Inner Semiconducting umaleko
3. I-Insulation Layer
4. I-Outer Semiconducting Layer
5. Isikrweqe sentsimbi
6. Sheath Layer
Ulwakhiwo lweCable Voltage ephantsi:
1. Umqhubi
2. I-Insulation Layer
3. Iteyiphu yentsimbi (Ayikho kwiintambo ezininzi zamandla ombane aphantsi)
4. Umaleko wesingxobo
Ukungafani okuphambili phakathi kombane ophezulu kunye neentambo zombane ophantsi zilele kubukho bomaleko we-semiconducting kunye nomaleko okhuselayo kwiintambo zombane ophezulu. Ngenxa yoko, iintambo zamandla ombane aphezulu zikholisa ukuba nongqimba olungqingqwa olungqingqwa, olukhokelela kulwakhiwo oluntsonkothileyo kunye neenkqubo zokuvelisa ezifunayo.
Isemiconducting umaleko:
I-semiconducting layer yangaphakathi isebenza ukuphucula umphumo wombane. Kwiintambo zombane ophezulu, ukusondela phakathi kwe-conductor kunye ne-insulation layer kunokudala izithuba, ezikhokelela ekukhutshweni okungaphelelanga okonakalisa ukugquma. Ukunciphisa oku, umaleko we-semiconducting usebenza njengenguqu phakathi kwe-conductor yesinyithi kunye ne-insulation layer. Ngokufanayo, umaleko we-semiconducting wangaphandle uthintela ukukhutshwa kwendawo phakathi komgangatho we-insulation kunye ne-sheath yensimbi.
Uluhlu olukhuselayo:
Umaleko okhuselayo wesinyithi kwiintambo zombane ophezulu usebenzela iinjongo ezintathu eziphambili:
1. I-Electric Field Shielding: Ikhusela ukuphazanyiswa kwangaphandle ngokukhusela indawo yombane eyenziwe ngaphakathi kwentambo yombane ophezulu.
2. Ukuqhutywa kweCapacitive Current ngexesha lokuSebenza: Isebenza njengendlela yokuhamba kwe-capacitive yangoku ngexesha lokusebenza kwentambo.
3. Umzila oMfutshane weSekethe yangoku: Kwimeko yokungaphumeleli kwe-insulation, i-shielding layer ibonelela ngendlela yokuvuza kwangoku ukugeleza emhlabeni, ukuphucula ukhuseleko.
Ukwahlula phakathi kweeCable Voltage eziPhezulu kunye neVolthage ephantsi:
1. Uvavanyo Lwesakhiwo: Iintambo zamandla ombane aphezulu zineeleya ezingaphezulu, ezibonakala xa uxobula umva umaleko ongaphandle ukuveza isikrweqe sentsimbi, isikhuselo, isigqubuthelo, kunye ne-conductor. Ngokwahlukileyo koko, iintambo zombane ophantsi zidla ngokubhentsisa ukugquma okanye iiconductors xa kususwa umaleko wangaphandle.
2. Ukutyeba kokugqunywa kwamandla ombane: Ukugqunywa kwentambo yombane ophakamileyo kungqindilili ngokuphawulekayo, ngokuqhelekileyo kudlula i-5 millimeters, ngelixa ukugqunywa kwentambo yombane ophantsi kuqhelekile ukuba phakathi kweemilimitha ezi-3.
3. Iimpawu zeCable: Umaleko ongaphandle wentambo uhlala uneempawu ezichaza uhlobo lwekhebula, indawo enqamlezileyo, i-voltage elinganisiweyo, ubude, kunye nezinye iiparamitha ezifanelekileyo.
Ukuqonda oku kungafani kolwakhiwo kunye nokusebenza kubalulekile ekukhetheni intambo efanelekileyo kwizicelo ezithile, ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko.
