Isingeniso
Kunoma iyiphi iphrojekthi yokwakha, ukukhetha uhlobo olulungile lwekhebula likagesi kubalulekile ekuphepheni, ukusebenza kahle, nokuphila isikhathi eside. Phakathi kwezinketho eziningi ezitholakalayo, izintambo zikagesi ze-NYY-J/O zigqama ngokuqina kwazo nokuguquguquka ezinhlobonhlobo zezilungiselelo zokufakwa. Kodwa wazi kanjani ukuthi iyiphi ikhebula le-NYY-J/O elilungele izidingo zakho zephrojekthi ethile? Lo mhlahlandlela uzokuhambisa ezintweni ezibalulekile nokucatshangelwa kokukhetha ikhebula lokulawula likagesi elilungile le-NYY-J/O, uqinisekise ukuthi iphrojekthi yakho yokwakha iphephile futhi iyonga.
Ayini Amakhebuli Okulawula Kagesi e-NYY-J/O?
Incazelo kanye Nokwakha
Izintambo ze-NYY-J/O ziwuhlobo lwekhebula lamandla aphansi-voltage elivame ukusetshenziswa ekufakweni okungaguquki. Iphawuleka ngokuqina kwayo, i-PVC emnyama (i-polyvinyl chloride), iklanyelwe ukuhlinzeka ngokusatshalaliswa kwamandla okuthembekile kuzo zombili izindawo zasendlini nezangaphandle. Igama elithi “NYY” limele amakhebuli angavimbeli ilangabi, amelana ne-UV, futhi afanele ukufakwa ngaphansi komhlaba. Isijobelelo esithi “J/O” sibhekisela ekucushweni kwentambo okuphansi, okuthi “J” okubonisa ukuthi ikhebuli ihlanganisa i-conductor yaphansi ephuzi ngokuluhlaza, kuyilapho u-“O” esho izintambo ezingenawo phansi.
Izicelo Ezivamile Ezokwakha
Ngenxa yokwahlukanisa kwawo okuqinile nokwakhiwa okumazombezombe, izintambo ze-NYY-J/O zisetshenziswa kakhulu kumaphrojekthi wokwakha ezimbonini nezohwebo. Izinhlelo zokusebenza ezijwayelekile zifaka:
- Ukusatshalaliswa kwamandla ezakhiweni
- Ukufakwa okugxilile, njengamasistimu epayipi
- Ukufakwa ngaphansi komhlaba (lapho kudingeka ukungcwatshwa okuqondile)
- Amanethiwekhi wamandla angaphandle, ngenxa yokumelana ne-UV nokuvikela isimo sezulu
Izinto Ezibalulekile Okufanele Zicatshangwe Lapho Ukhetha Amakhebula E-NYY-J/O
1. Isilinganiso samandla kagesi
Intambo ngayinye ye-NYY-J/O yakhelwe ukuphatha amazinga kagesi athile. Ngokujwayelekile, lezi zintambo zisebenza kumabanga aphansi-voltage (0.6/1 kV), afanele izicelo eziningi zokwakha. Ukukhetha ikhebula elinesilinganiso samandla kagesi esifanele kubalulekile, njengoba ukubukela phansi izidingo zamandla kagesi kungaholela ekushiseni ngokweqile, ekulimaleni kwe-insulation, kanye nezingozi zomlilo ezingaba khona. Kuzinhlelo zokusebenza zamandla aphezulu, qinisekisa ukuthi ikhebuli ingakwazi ukuphatha umthwalo olindelekile.
2. Izici Zemvelo
Indawo yokufaka ithinta ngokuqondile ukusebenza kwekhebula. Izintambo ze-NYY-J/O zaziwa ngokukhuthazela kwazo ezindaweni eziyinselele, kodwa ukucabangela izici ezithile kusabalulekile:
- Ukumelana Nomswakama: Khetha izintambo ezinokumelana nomswakama ophezulu endaweni engaphansi noma eswakeme.
- Ukumelana ne-UV: Uma amakhebuli efakwe ngaphandle, qinisekisa ukuthi ane-sheathing ekwazi ukumelana ne-UV.
- Izinga Lokushisa: Hlola izilinganiso zezinga lokushisa ukuze uvimbele umonakalo ezimeni ezimbi kakhulu. Izintambo ezijwayelekile ze-NYY zivame ukuba nezinga lokushisa elingu--40°C kuya ku-+70°C.
3. Ukuguquguquka Kwekhebula kanye Nezidingo Zokufaka
Ukuvumelana nezimo kwezintambo ze-NYY-J/O kuthinta ukukhululeka kokufakwa. Amakhebuli anokuguquguquka okuphezulu kulula ukuhamba ezindaweni eziqinile namapayipi. Ngokufakwa okudinga umzila oyinkimbinkimbi, khetha izintambo eziklanywe ngokuguquguquka okuthuthukisiwe ukuze ugweme ukuguga ngesikhathi sokufakwa. Izintambo ezijwayelekile ze-NYY zilungele ukufakwa okungaguquki nokunyakaza okuncane kodwa zingadinga ukunakekelwa okwengeziwe uma zifakwe ezindaweni ezinokucindezeleka komshini.
4. Impahla kakhondatha kanye neNdawo Ehlukene
Izinto kanye nosayizi wekhondatha kunomthelela kumthamo wokuthwala wamanje wekhebula nokusebenza kahle. I-Copper iyinto ejwayeleke kakhulu ye-conductor yezintambo ze-NYY-J/O ngenxa yokuguquguquka kwayo okuphezulu nokuqina. Ukwengeza, ukukhetha indawo efanele ye-cross-sectional kuqinisekisa ukuthi ikhebula lingakwazi ukuphatha umthwalo kagesi ohlosiwe ngaphandle kokushisa ngokweqile.
Izinzuzo zezintambo zikagesi ze-NYY-J/O zamaphrojekthi Wokwakha
Ukuqina Okuthuthukisiwe Nokwethenjelwa
Izintambo ze-NYY-J/O zakhiwe ukuze zihlale, ngisho nasezimweni ezinzima. Ukufakwa kwabo okuqinile kwe-PVC kuvikela ekulimaleni ngokomzimba, amakhemikhali, nezimo zezulu, kuqinisekisa impilo ende yesevisi nokunciphisa isidingo sokunakekelwa njalo noma ukushintshwa.
Izinketho Zokusebenza Ezihlukahlukene
Lawa makhebuli aklanyelwe izimo ezihlukahlukene zokufakwa, okuhlanganisa izilungiselelo ezingaphansi komhlaba nangaphandle. Izakhiwo zabo ezivimbela umlilo kanye nomklamo omangelengele kubenza bafaneleke kokubili izicelo zokuhlala nezimboni, okuhlinzeka ngokuguquguquka kwezidingo ezihlukahlukene zephrojekthi.
Amazinga Nezitifiketi Okufanele Ukubheke
Ikhwalithi kanye Nezinga Lokuphepha (isb, IEC, VDE)
Lapho ukhetha izintambo ze-NYY-J/O, bheka izitifiketi ezifana nezindinganiso ze-IEC (International Electrotechnical Commission) kanye ne-VDE (German Electrical Engineering Association), eziqinisekisa ukuthi amakhebuli ahlangabezana nezimfuneko eziqinile zokuphepha nokusebenza. Ukuthobelana nalawa mazinga kuqinisekisa ukuthi amakhebuli afanele amaphrojekthi wokwakha futhi ahlangabezana nezilinganiso zekhwalithi ezibalulekile.
I-Fire Resistance kanye ne-Flame Retardant Properties
Ukuphepha emlilweni kuyinto ehamba phambili ekwakhiweni. Izintambo ze-NYY-J/O zivame ukuza nezici ezivimbela amalangabi, ezinciphisa ingozi yokubhebhetheka komlilo uma kwenzeka kuba namaphutha kagesi. Kumaphrojekthi asezindaweni ezingezwani nomlilo, bheka izintambo ezilinganiselwe ngokuvumelana nezindinganiso ezifanele zokumelana nomlilo ukuze kuthuthukiswe ukuphepha kukonke.
Amaphutha Avamile Okufanele Ugwenywe Lapho Ukhetha Izintambo Ze-NYY-J/O
Ukunciphisa Izidingo Zogesi
Ngaso sonke isikhathi khetha ikhebula elilinganiselwe phezulu kancane kunevoltheji ehlosiwe ukuze uqinisekise ukuphepha nokuvikela umonakalo. Ukufaka ikhebula elinezinga eliphansi kungaholela ekulimaleni kwe-insulation kanye nokwehluleka.
Ukunganaki Izimo Zemvelo
Ukukhohlwa ukulandisa ngezici zemvelo kungaholela ekulungiseni okubizayo kanye nezingozi zokuphepha. Kungakhathaliseki ukuthi okokufakwa ngaphansi komhlaba, ukuchayeka elangeni, noma ezindaweni eziswakeme, qinisekisa njalo ukuthi ikhebula elikhethiwe liyazifanela lezi zimo.
Ukukhetha Usayizi Wekhebula Ongalungile noma I-Conductor Material
Ukukhetha usayizi wekhebula olungile kanye nezinto zekhondakta kubalulekile. Izintambo ezinosayizi ongaphansi zingashisa kakhulu, kuyilapho izintambo ezinosayizi omkhulu zingabiza kakhulu kunalokho okudingekayo. Ukwengeza, izikhondatha zethusi zithembeke kakhulu futhi zisebenza kahle ezinhlelweni eziningi, nakuba i-aluminiyamu nayo iyinketho lapho isisindo nokongiwa kwezindleko kubekwa kuqala.
Imikhuba Engcono Kakhulu Yokufaka Izintambo zikagesi ze-NYY-J/O
Ukuhlela Indlela Yokufaka
Indlela yokufaka ehlelwe kahle iqinisekisa ukuthi izintambo zingafakwa ngaphandle kokugoba okungadingekile noma ukungezwani. Hlela umzila wakho ngokucophelela ukuze ugweme izithiyo, ezingase zidinge ukugoba noma ukwelula ngokweqile, ukwehlisa ukuphila kwekhebula.
Amasu Afanele Wokugawula kanye Nokuhlanganisa
Ukubeka phansi kubalulekile ekuphepheni, ikakhulukazi ezinhlelweni zokusebenza zamandla aphezulu. Izintambo ze-NYY-J ezinamakhondaktha aphansi (okuluhlaza-ophuzi) zinikeza ukuphepha okwengeziwe ngokuvumela ukuxhumana okulula ohlelweni lokubeka phansi.
Ukuhlola Nokuhlola Ngaphambi Kokusetshenziswa
Ngaphambi kokunika amandla noma yikuphi ukufakwa kukagesi, yenza ukuhlola nokuhlola okuphelele. Qinisekisa ukuthi konke ukuxhumana kuvikelekile nokuthi izintambo azilimalanga ngesikhathi ukufakwa. Ukuhlola ukuqhubeka, ukumelana nokufakwa kwe-insulation, kanye nokubeka phansi okulungile kusiza ukuvimbela izinkinga zokuphepha futhi kuqinisekise ukusebenza okuthembekile.
Isiphetho
Ukukhetha ikhebula elilungile le-NYY-J/O kuwukutshalwa kwezimali ekuphepheni, ekusebenzeni kahle, nasekuphileni isikhathi eside kwephrojekthi yakho yokwakha. Ngokucabangela izici ezifana nesilinganiso sikagesi, ukumelana nemvelo, ukuguquguquka, kanye nezitifiketi, ungenza ukukhetha unolwazi oluhambisana nezidingo zephrojekthi yakho. Ukuqinisekisa ukufakwa okufanele kanye nokulandela izinqubo ezihamba phambili kuthuthukisa ukuthembeka nokuqina kokusetha kwakho ugesi. Ngezintambo ezifanele ze-NYY-J/O, ungaqiniseka ukuthi iphrojekthi yakho izohamba kahle, ngokuphepha, nangempumelelo.
Kusukela ngo-2009,I-Danyang Winpower Wire neCable Mfg Co., Ltd.ibilima emkhakheni wezintambo zikagesi neze-elekthronikhi iminyaka ecishe ibe ngu-15, iqongelela ingcebo yesipiliyoni semboni kanye nokuqanjwa okusha kwezobuchwepheshe. Sigxila ekuletheni izixazululo ezisezingeni eliphezulu, ezizungezile kanye nezixazululo zezintambo emakethe, futhi umkhiqizo ngamunye uqinisekiswe ngokuqinile yizinhlangano ezigunyaziwe zaseYurophu nezaseMelika, ezifanele izidingo zokuxhuma ezimeni ezahlukahlukene.
