Izixhobo zekhebula ze-35kV kunye ne-Under Medium Voltage

Izixhobo zentambo zohlobo lwe-cast zisebenzisa izinto ze-thermosetting resin, ezifakwe kwindawo yokubumba okanye kwibhokisi ekupheleni kwentambo okanye kwijoyinti emva konyango, kwaye izixhobo zentambo zenziwa emva kokunyibilika. Zifaneleke ngokukodwa ekudibaneni kweentambo zeplastiki ezifakwe kwi-insulation kunye neentambo ezifakwe kwi-insulation ezifakwe ephepheni.

Izihlanganisi ezahlulweyovumela iintambo nezinye izixhobo kunye neentambo ukuba zidibanise okanye zikhuphe izixhobo zentambo ezigqunywe ngokupheleleyo, ezifana neeterminals, iijoyinti, kunye neejoyinti zamasebe. Izinto eziphambili zokusetyenziswaizihlanganisi ezahlulweyoziikhabhathi zokutshintsha ezivalwe ngokupheleleyo, i-RMU, iibhokisi zesebe leentambo kunye nezinye izixhobo, ezinokuthathwa njengohlobo olutsha lwesiphelo sentambo. Kwaye ngaphezulu kusetyenziswa ulwakhiwo lwesiphelo esenziwe ngaphambili.

Akunzima ukubona kuluhlu lwemveliso yezixhobo zekhebula ezikhankanyiweyo apha ngasentla ukuba ukwenziwa kwangaphambili kunye neteknoloji yokunciphisa ngokubandayo enokwenza lula iimfuno zokufakela kwindawo sele ithathe indawo ebalulekileyo ekuphuhlisweni kwezixhobo zekhebula.

Ukusetyenziswa kwetekhnoloji entsha kwiimveliso zezixhobo zekhebula:

Iimfuno zobugcisa ezisisiseko zoqhagamshelo lwe-conductor kuqhagamshelo lwe-conductor zezi: uqhagamshelo oluhle lwe-conductor: kwi-terminal, i-cable conductive core, i-outlet rod, kunye ne-terminal kufuneka ziqhagamshelwe kakuhle; kwi-intermediate joint, i-cable conductor kunye nombhobho wokudibanisa kufuneka ziqhagamshelwe kakuhle. Oko kukuthi, ukumelana koqhagamshelwano lwendawo yokudibanisa kufuneka kube kuncinci kwaye kuzinze. Xa kuthelekiswa nokuxhathisa kweengcingo ezinobude obufanayo kunye ne-cross-section efanayo, umlinganiselo weengcingo ezisandula ukufakwa akufuneki ube ngaphezulu kwe-1.

Okwangoku, iteknoloji yokuqhobosha isetyenziswa kakhulu kwindawo, nto leyo efuna izixhobo ezithile zobungcali. Ngeteknoloji yoqhagamshelo lwebholiti, kufuneka isikrufu se-torque kuphela ngexesha lokwakhiwa kwendawo ukuze kuhlangatyezwane neemfuno zobugcisa ezisisiseko zoqhagamshelo lwe-conductor. Oku kwenza kube lula iimfuno zobungcali zezixhobo zokufakela. Kwaye kwiintambo ze-aluminium ezifuna ukususa umaleko we-oxide ongekho mqhubi, akukho mfuneko yokwenza unyango olukhethekileyo lwe-deoxidation kwangaphambili.

Izinto zokuvala ubushushu Izinto zerabha ze-EPDM kunye nerabha ye-silicone zisetyenziswa kakhulu kwizixhobo zekhebula ezenziwe ngaphambili. Kwicandelo lezixhobo zekhebula ezine-voltage ephezulu, xa kuthelekiswa, zinokwahlulwa zibe yisakhiwo saseYurophu kunye nerabha ye-silicone njengesixhobo esisisiseko kunye nesakhiwo se-EPDM sesitayile saseJapan esinerabha ye-acrylic njengesixhobo esisisiseko. Kwicandelo le-voltage ephakathi, izixhobo zekhebula zerabha ze-EPDM eziphuculweyo zinamandla angcono oomatshini kunye nokumelana nokukrazuka kuneemveliso zerabha ze-silicone ezifanayo.

Itekhnoloji yokwandisa kwindawo ikwayindlela yokufakela iimveliso zezixhobo zekhebula ezinciphayo ezibandayo, oko kukuthi, kwiiyure ezimbalwa ngaphambi kokufakwa, iindawo ezinciphayo ezibandayo zandiswa kwindawo ngezixhobo ezilula ezilahlwayo. Ithintela ukulahleka kokusebenza okuncinci kweemveliso eziqhelekileyo ezinciphayo ezibandayo ngexesha lokuthuthwa kunye nokugcinwa ixesha elide, ngaloo ndlela ibonelela ngoxinzelelo lwe-radial oluhlala luhleli, oluhlala ixesha elide noluthembekileyo. Ifanelekile ngakumbi njengeendawo ezingasetyenziswayo zenkqubo. Ngamafutshane, ukuze kube lula ukufakwa kwindawo kunye nokuqinisekisa umgangatho wokufakwa, kunciphisa iimfuno ezigqithisileyo kwinqanaba lobugcisa labafaki kwindawo. Ukwenziwa kwangaphambili kunye nokulula kuya kuba yindlela ephambili yophuhliso lwetekhnoloji yezixhobo zekhebula kwixesha elizayo. Ukwenziwa kwangaphambili kweemveliso kunokuvavanywa ngaphambi kokuba kuphume kumzi-mveliso.

Izixhobo zekhebula ezicothayo ziya kuba zezona ziphambili kwindawo, ngaloo ndlela ziqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo kwenkqubo yamandla, kwaye zifezekisa indibaniselwano engcono kakhulu yetekhnoloji kunye noqoqosho.
