Siyazi ukuthi izintambo ezahlukene zinokusebenza okuhlukene ngakho-ke izakhiwo ezahlukene. Ngokuvamile, ikhebula lakhiwa i-conductor, ungqimba oluyisivikelo, ungqimba olufakwa ngaphakathi, ungqimba lwe-sheath, kanye nongqimba lwezikhali. Kuye ngezici, isakhiwo siyahlukahluka. Kodwa-ke, abantu abaningi abacaci kahle ngomehluko phakathi kwezintambo zokuvala, okokuvikela, kanye nezingqimba zamakhebuli. Ake sizihlukanise ukuze siqonde kangcono.
(1) I-Insulation Layer
Isendlalelo se-insulation kukhebula ngokuyinhloko sinikeza ukwahlukanisa phakathi kwekhondakta nendawo ezungezile noma amakhondaktha aseduze. Iqinisekisa ukuthi amandla kagesi, amagagasi kagesi, noma amasignali okukhanya athwelwe umqhubi adluliselwa kuphela eduze kwekhondakta ngaphandle kokuvuza ngaphandle, kuyilapho futhi ivikela izinto zangaphandle nabasebenzi. Ukusebenza kwe-insulation kunquma ngokuqondile i-voltage elinganiselwe ikhebula engakwazi ukumelana nayo kanye nempilo yayo yesevisi, okuyenza ibe enye yezingxenye eziyinhloko zekhebula.
Izinto zokufaka ikhebula ngokuvamile zingahlukaniswa zibe izinto zokufakwa kwepulasitiki kanye nezinto zokufakwa kwerabha. Izintambo zikagesi ezifakwe epulasitiki, njengoba negama lisho, zinezingqimba zokufakelwa ezenziwe ngamapulasitiki akhishwe. Amapulasitiki ajwayelekile afaka i-Polyvinyl Chloride (PVC), i-Polyethylene (PE),I-Cross-Linked Polyethylene (XLPE), kanye Nentuthu Ephansi Zero Halogen (LSZH). Phakathi kwazo, i-XLPE isetshenziswa kabanzi kumakhebula aphakathi nendawo naphezulu ngenxa yezakhiwo zayo ezinhle kakhulu zikagesi nezemishini, kanye nokumelana nokuguga okushisayo okuphezulu nokusebenza kwe-dielectric.
Ngakolunye uhlangothi, izintambo zikagesi ezifakwe enjoloba zenziwe ngenjoloba exutshwe nezithasiselo ezihlukahlukene futhi zicutshungulwe zibe inzalo. Izinto ezijwayelekile zokuvala injoloba zifaka izingxube zenjoloba-styrene zemvelo, i-EPDM (irabha ye-Ethylene Propylene Diene Monomer), kanye nerabha ye-butyl. Lezi zinto ziyaguquguquka futhi zinwebeka, zilungele ukunyakaza njalo kanye ne-radius encane yokugoba. Kuzinhlelo zokusebenza ezifana nezimayini, imikhumbi, nezikhumulo, lapho ukumelana nokuhuzuka, ukumelana nowoyela, nokuguquguquka kubaluleke kakhulu, amakhebuli afakwe irabha adlala indima engenakushintshwa.
(2) Ungqimba Lomgodla
Isendlalelo se-sheath senza izintambo zivumelane nezimo ezihlukahlukene zokusetshenziswa. Isetshenziswa phezu kwesendlalelo sokufakelwa, indima yayo eyinhloko ukuvikela izendlalelo zangaphakathi zekhebula ekulimaleni komshini kanye nokugqwala kwamakhemikhali, kuyilapho kuthuthukisa amandla emishini ekhebula, ihlinzeka ngokumelana okuqinile nokucindezelayo. I-sheath iqinisekisa ukuthi ikhebula livikelekile ekucindezelekeni kwemishini nasezicini zemvelo ezifana namanzi, ukukhanya kwelanga, ukugqwala kwezinto eziphilayo, nomlilo, ngaleyo ndlela kugcina ukusebenza kukagesi okuzinzile kwesikhathi eside. Ikhwalithi ye-sheath ithinta ngqo impilo yesevisi yekhebula.
Isendlalelo se-sheath sinikeza ukumelana nomlilo, ukubambezeleka komlilo, ukumelana nowoyela, ukumelana ne-asidi ne-alkali, nokumelana ne-UV. Ngokuya ngohlelo lokusebenza, izingqimba ze-sheath zingahlukaniswa zibe izinhlobo ezintathu eziyinhloko: amashethi ensimbi (okuhlanganisa ne-outer sheath), amashethi erabha / epulasitiki, namashethi ayinhlanganisela. Izigqoko zenjoloba/ipulasitiki neziyinhlanganisela azivimbeli nje kuphela ukulimala kwemishini kodwa futhi zinikeza ukuvimbela amanzi, ukugoba amalangabi, ukumelana nomlilo, nokumelana nokugqwala. Ezimweni ezinzima ezifana nomswakama ophezulu, imigudu engaphansi komhlaba, nezitshalo zamakhemikhali, ukusebenza kongqimba lwesheath kubaluleke kakhulu. Izinto ze-sheath ezisezingeni eliphezulu azigcini nje ngokunweba impilo yesevisi yekhebula kodwa futhi zithuthukisa kakhulu ukuphepha nokuthembeka ngesikhathi sokusebenza.
(3) Isendlalelo Esivikelayo
Isendlalelo esivikelayo kukhebula sihlukaniswe sibe isivikelo sangaphakathi nesivikelo sangaphandle. Lezi zingqimba ziqinisekisa ukuthintana okuhle phakathi kwe-conductor kanye ne-insulation, kanye naphakathi kwe-insulation kanye ne-sheath yangaphakathi, isusa ukwanda kwenkundla kagesi engaphezulu okubangelwa izindawo ezimaholo zamakhondakta noma izendlalelo zangaphakathi. Amakhebuli kagesi aphakathi nendawo naphezulu ngokuvamile ane-conductor shielding ne-insulation shielding, kuyilapho amanye amakhebuli ane-low-voltage angase angahlomeki ngezingqimba ezivikelayo.
Ukuvikela kungaba i-semi-conductive shielding noma i-metallic shielding. Amafomu okuvikela ensimbi avamile ahlanganisa ukugoqa itheyiphu yethusi, ukuluka kwentambo yethusi, kanye nokugoqa kwe-aluminium foil-polyester composite tape longitudinal. Izintambo ezivikelekile zivame ukusebenzisa izakhiwo ezifana nezihlangu ezisontekile ezimbili, isivikelo seqembu, noma isivikelo sonke. Imiklamo enjalo ihlinzeka ngokulahleka kwe-dielectric ephansi, amandla okudlulisa aqinile, nokusebenza okuhle kakhulu kokunqanda ukuphazamiseka, okuvumela ukudluliswa okuthembekile kwamasiginali we-analog abuthakathaka kanye nokumelana nokuphazamiseka okunamandla kazibuthe kagesi ezindaweni zezimboni. Asetshenziswa kakhulu ekuphehleni ugesi, i-metallurgy, i-petroleum, izimboni zamakhemikhali, ezokuthutha ngololiwe, kanye nezinhlelo zokulawula ukukhiqiza ezizenzakalelayo.
Ngokuqondene nezinto zokuvikela, ukuvikela kwangaphakathi kuvame ukusebenzisa iphepha elenziwe ngensimbi noma izinto ezi-semi-conductive, kuyilapho ukuvikela kwangaphandle kungase kuhlanganise ukugoqa itheyiphu yethusi noma ukuluka ucingo lwethusi. Izinto zokuluka ngokuvamile ziyithusi elingenalutho noma ithusi elithayiwe, futhi kwezinye izimo izintambo zethusi ezihlanganiswe ngesiliva zokumelana nokugqwala okuthuthukisiwe kanye nokuhamba kahle. Isakhiwo esivikelayo esiklanywe kahle asigcini nje ngokuthuthukisa ukusebenza kukagesi kwezintambo kodwa futhi sinciphisa ngempumelelo ukuphazamiseka kwemisebe kagesi kumishini eseduze. Ezimweni zanamuhla ezifakwe ugesi kakhulu futhi ezishayelwa ulwazi, ukubaluleka kokuvikela kuya ngokuya kugqama.
Sengiphetha, lena umehluko kanye nemisebenzi yokuvala amakhebula, ukuvikela, nezingqimba zesheath. I-ONE WORLD ikhumbuza wonke umuntu ukuthi izintambo zihlobene kakhulu nokuphila nokuphepha kwempahla. Izintambo ezisezingeni eliphansi akufanele neze zisetshenziswe; njalo kuvela kubakhiqizi bamakhebula abahlonishwayo.
I-ONE WORLD igxile ekuhlinzekeni ngezinto zokusetshenziswa zamakhebuli futhi izimisele ukuhlinzeka amakhasimende ngezixazululo zekhwalithi ephezulu. Imikhiqizo yethu imboza ukwahlukanisa okuhlukahlukene, i-sheath, nezinto zokuvikela, njenge-XLPE, i-PVC, i-LSZH, i-Aluminium Foil Mylar Tape, i-Copper Tape,I-Mica Tape, futhi nokuningi. Ngekhwalithi ezinzile kanye nesevisi ephelele, sinikeza ukwesekwa okuqinile kokukhiqizwa kwamakhebula emhlabeni wonke.
