Zeziphi iingozi zeengcingo ezingafanelekanga kunye neentambo?

Iingcingo kunye neentamboludidi olukhulu lweemveliso zombane ezisetyenziselwa ukuhambisa umbane, ukuhambisa ulwazi kunye nokuqonda uguqulo lwamandla ombane. Iingcingo kunye neentambo zidlala indima ebalulekileyo kuyo yonke imisebenzi yezoqoqosho kunye nobomi boluntu. Kunokuthiwa naphi na apho kukho abantu abahlala khona, naphi na apho kukho imveliso, ukuthutha kunye nayo yonke imisebenzi yezoqoqosho, iingcingo kunye neentambo ziyimfuneko. Ngoko ke, umgangatho weengcingo kunye neentambo zichaphazela ngqo ubomi bethu.

Iimveliso ezingafanelekanga ubukhulu becala zineengxaki kulwakhiwo, ubungakanani bomqhubi, ukuxhathisa komqhubi, ukugquma kunye nokuqina kwe-sheath ngaphambi kokuguga. Abathengi abasebenzisa iimveliso ezinjalo bavame ukuvuza, ukutshitshiswa kombane kunye nomlilo. Ezi mveliso zingaphantsi ziye zangcwaba iingozi ezininzi ezifihliweyo ekusebenzeni okuqhelekileyo kwenkqubo yamandla.

Emva kwenqanaba elinye lokumisa (isiphaluka esifutshane) ingozi yenzeke kwiiingcingo kunye neentambo, isixhobo sokukhusela i-relay sibangela ukuba iingcingo kunye neentambo zigqithise ngokugqithiseleyo ngenxa yokungaphumeleli kwesenzo sokugqibela ukunqumla iphoso, okubangelwa ukutshisa okuzenzekelayo kwe-insulation layer.

Iingcingo kunye neentambo ezinamandla afanelekileyo kunye nobude ngaphambi kokuguga kwe-sheath. Amandla okuqina angafanelekanga kunye nokwandiswa kwe-sheath yokukhusela ngaphambi kokuguga bufutshane ngokuthe ngqo ubomi benkonzo yeengcingo kunye neentambo. Ukongezelela, ngexesha lokwakhiwa okanye kwindawo apho amandla ahlala ixesha elide kwaye ubushushu buphezulu, i-insulator iyakwazi ukuphuka, okubangela ukuba ii-conductor eziphilayo eziveziweyo kunye nomngcipheko weesekethe ezimfutshane zombane.

Iingcingo ezinokumelana ne-conductor engafanelekanga. Ukuchasana kwe-conductor ikakhulu kusalathiso esibalulekileyo sokuvavanya ukuba ingaba i-conductor material kunye ne-cross-section yeengcingo kunye neentambo zihlangabezana neemfuno. Xa ukuchasana kwe-conductor kudlula umgangatho, ukulahlekelwa kwangoku odlulayo kumgca kunyuswa, okwenza kube nzima ukufudumeza iingcingo kunye neentambo. Esona sizathu siphambili sokumelana nomqhubi ongafanelekanga kukuba, ukuze kuncitshiswe iindleko, amashishini acutha izinto zobhedu, ezibalelwa kuma-80% exabiso lempahla ekrwada, mhlawumbi ngokunciphisa indawo enqamlezileyo yomqhubi okanye ngokusebenzisa ubhedu oluhlaziyiweyo. ukungcola okuphezulu kakhulu. Oku kubangela ukuxhathisa komqhubi weiingcingo kunye neentamboukugqithisa kakhulu umgangatho. Kwinkqubo yokusetyenziswa, akulula nje ukubangela umlilo, kodwa kwakhona ukukhawuleza ukuguga kwe-insulation layer ehlanganiswe ngeengcingo.
