Ekwakhiweni okuhlelekile kwe-Newamelana nomliloIzintambo,i-polyethylene exhumene nesiphambano (i-XLPE) ifakiweamakhebuli asetshenziswa kabanzi. Babonisa ukusebenza okuhle kukagesi, izakhiwo zemishini, kanye nokuqina kwemvelo. Kuboniswa amazinga okushisa aphezulu aphezulu, amakhono amakhulu okudlulisa, ukubeka okungavinjelwe, kanye nokufakwa okulula nokulungiswa, amelela ukuqondiswa kwentuthuko kwezintambo ezintsha.
1. Idizayini ye-Cable Cocructor
UHLELO LESIKHATHI NEZINHLOKO: Isakhiwo somqalisi sisebenzisa uhlobo lwesibili olwenziwe ngomqhubi weCompact, esebenzisa (1 + 6 + 12 + 18 + 24) Isakhiwo esijwayelekile. Ehlathini elijwayelekile, ungqimba oluphakathi luqukethe ucingo olulodwa, ungqimba lwesibili lunezintambo eziyisithupha, futhi izingqimba ezalandela ezalandela ziyehluka ngezintambo eziyisithupha. Ungqimba olungaphandle lwesobunxele luhlanekezelwe, kanti ezinye izingqimba eziseduze zidonswa ngakolunye uhlangothi. Izintambo ziyindilinga futhi yobubanzi obulinganayo, ukuqinisekisa ukuqina kulesi sakhiwo esidabukisayo. Isakhiwo esihlangene: Ngokusebenzisana, indawo yomqalisi iba bushelelezi, ukugwema ukugxila kwamasimu kagesi. Ngasikhathi sinye, kuvimbela izinto eziqhutshwa yisikhathi ekungeneni okuyisisekelo se-wire ngesikhathi sokufakelwa kwe-desitlesion, ukuvikela ngempumelelo ukungeniswa komswakama nokuqinisekisa ngezinga elithile lokuguquguquka. Abaqhubi abahlanzekile banokuguquguquka okuhle, ukuthembeka namandla aphezulu.
2. Ungqimba lwentambo yekhebulaUkusongoza icebo
Indima yesendlalelo sokufakwayo ukuqinisekisa ukusebenza kukagesi kwentambo futhi uvikele ukugeleza kwamanje eceleni komqhubi kusuka ngaphandle okuphuma ngaphandle. Isakhiwo se-Extresion siqashiwe, ngeIndwangu ye-XLPEkukhethwe ukufakwa. I-XLPE inikezela ukusebenza okuphezulu ngokuqhathaniswa ne-polyethylene, inazo ama-plical kagesi wokufakelwa kukagesi, okubonakaliswa yi-dielectric constants encane (ε) kanye nokulahleka okuphansi kwe-dielectric. Kuyinto ekahle yokufakelwa kwezingubo eziphakeme kakhulu. Amandla awo wokumelana wevolumu kanye namandla okuphuka ahlala engashintshiwe ngisho nangemva kwezinsuku eziyisikhombisa zokuntywiliselwa emanzini. Ngakho-ke, kusetshenziswa kabanzi ekufakweni kwentambo. Kodwa-ke, inendawo ephansi yokuncibilika. Lapho isetshenziswa kumakhebuli, amaphutha we-scord-relituit angemuva angadala ukunyuka kwamazinga okushisa, okuholele ekuthambekekeni nasekuguqukeni kwe-polyethylene, okuholele ekulimazeni kokufakelwa. Ukugcina izinzuzo ze-polyethylene, kuvimbela ukunqamula, kuthuthukisa ukumelana kwayo nokumelana nokuvimbela ukuqhekeka kwengcindezi yemvelo, ukwenza izinto ze-polyethylene ezixhumene ne-polyethylene ezintweni ezifanele zokufakelwa.
3. I-Cable ehlakazayo nokugoqa
Inhloso yokuhlanza ikhebula nokusonga ukuvikela ukufakwa, kuqinisekiswe umnyombo oqinile wekhebula, futhi kuvikele ukufakwa kwamakhebula kanye nama-fillers, kuqinisekisa ukuzuliswa komgogodla. Le khasiIbhande eligoqayo le-Flame-retardantinikeza izakhiwo ezithile ze-flame-retardant.
Izinto zokwakha amakhebula nokugoqa: impahla esongelayo i-flame ephezulu-retardantIndwangu engalukiweIbhande, elinamandla ashubile kanye ne-Flame Retardancy Index ye-NO AN DOURN DER 50% Oxygen Index. I-Filler Material isebenzisa izintambo ze-Flame-Retardant I-Inorganic Phepha Ropes (izintambo zamaminerali), ezithambile, ngenkomba ye-oxygen ye-NO-30%. Izidingo zokuhlanzeka kwekhebula nokugoqa kufaka ukukhetha ububanzi beqembu elisongelayo elisuselwa kububanzi obuyinhloko kanye ne-angle yebhendi, kanye nokugqagqana noma ukuhlukaniswa kokugoqa. Isiqondisi sokusonga sesokunxele. Amabhande aphezulu we-flame-retardant ayadingeka kumabhande we-flame-retardant. Ukuvikelwa kokushisa kwe-filler impahla kufanele kuhambisane nokushisa kwentambo yentambo, futhi ukwakheka kwalo akufanele kuhlanganyele kabi neizinto ezibonakalayo ze-sheath.Kufanele kususwe ngaphandle kokulimaza umnyombo wokufaka.
