Izivalo zikagesi ziza ngobukhulu obuhlukahlukene, ukwakheka, izinto zokwakha, kanye nemiklamo.Nakuba zonke zinezinhloso ezifanayo engqondweni - ukuvikela izinto zikagesi ezivalelwe endaweni ezungezile, ukuvikela abasebenzisi ekushayweni kukagesi, nokufaka izinto zikagesi - zingahluka kakhulu.Ngenxa yalokho, izidingo zezindawo ezivaliwe zikagesi zithonywa kakhulu izidingo zabasebenzisi.
Uma sikhuluma ngezidingo zemboni zezivalo zikagesi, sivame ukukhuluma ngamazinga kunemithetho eyisibopho (okungukuthi, izidingo).Lezi zindinganiso zenza kube lula ukuxhumana phakathi kwabakhiqizi nabathengi.Baphinde bakhuthaze ukuphepha, ukuklama okuphumelelayo, nokusebenza okuphezulu.Namuhla, sizobheka ezinye zezindinganiso ezivame kakhulu zokuvaleka, kanye nokunye okukhathazayo okuyinhloko abantu ababa nakho lapho be-oda ikhabethe likagesi noma indawo ebiyelwe.
Amazinga Ajwayelekile Ezindawo Ezivaliwe
Abakhiqizi abaningi bezindawo ezivalekile zikagesi bathobela izidingo zokuphepha ezibekwe yinhlangano yohlu ehloniphekile.E-United States, i-Underwriters Laboratories (UL), iNational Electrical Manufacturers Association (NEMA), kanye ne-Intertek yizinhlangano ezintathu ezinkulu ezifaka ohlwini.Abakhiqizi abaningi basebenzisa i-International Electrotechnical Commission esikalini somhlaba (IEC), ebeka umndeni wezindinganiso zokuvaleka kukagesi, kanye ne-Institute of Electrical and Electronics Engineers (IEEE), inhlangano yochwepheshe bezobuchwepheshe ebeka izindinganiso zokuthuthukisa ubuchwepheshe futhi kuzuze isintu. .
Izindinganiso zikagesi ezintathu ezivame kakhulu zishicilelwa yi-IEC, NEMA, kanye ne-UL, njengoba kuphawuliwe ngaphambilini.Kufanele ubheke ngokukhethekile ukushicilelwa kwe-NEMA 250, IEC 60529, kanye ne-UL 50 kanye ne-50E.
I-IEC 60529
Amaleveli okuvikela angenayo akhonjwa kusetshenziswa lawa makhodi (abuye aziwe ngokuthi Izinombolo Zokuzilibazisa) (owaziwa nangokuthi izilinganiso ze-IP).Bachaza ukuthi indawo ebiyelwe ikuvikela kahle kangakanani okukuyo emswakameni, othulini, endle, kubantu, nakwezinye izakhi.Nakuba izinga livumela ukuzihlola, abakhiqizi abaningana bancamela ukuthi imikhiqizo yabo ihlolwe ngokuzimela ukuthi iyahambisana yini.
I-NEMA 250
I-NEMA ihlinzeka ngokuvikeleka kokungena ngendlela efanayo ne-IEC eyenza ngayo.Nokho, kufaka phakathi ukwakhiwa (ubuncane bezindinganiso zokuklama), ukusebenza, ukuhlola, ukugqwala, nezinye izihloko.I-NEMA ihlukanisa izindawo ezivalekile ngokusekelwe ohlotsheni lwazo kunezilinganiso zazo ze-IP.Iphinde ivumele ukuzithobela, okususa isidingo sokuhlolwa kwefekthri.
I-UL 50 kanye ne-50E
Izindinganiso ze-UL zisekelwe ekucacisweni kwe-NEMA, kodwa futhi zidinga ukuhlolwa okuvela eceleni kanye nokuhlolwa kwendawo ukuze kuqinisekiswe ukuthotshelwa kwemithetho.Izindinganiso ze-NEMA zenkampani zingafakazelwa ngesitifiketi se-UL.
Ukuvikelwa kokungena kubhekwe kuwo womathathu amazinga.Bahlola ikhono lendawo ebiyelwe ukuqapha ekungeneni kwezinto eziqinile (njengothuli) noketshezi (njengamanzi).Baphinde bacabangele ukuvikelwa komuntu ezintweni eziyingozi zendawo ebiyelwe.
Amandla, ukuvala, okokusebenza/ukuphela, ukulengela, ukuvutha, ukungena komoya, ukukhweza, nokuvikela okushisayo konke kumbozwe yizindinganiso ze-UL kanye ne-NEMA yokuklama indawo ebiyelwe.I-Bonding kanye nesisekelo nayo iqondiswa yi-UL.
Ukubaluleka Kwamazinga
Abakhiqizi nabathengi bangaxhumana kalula mayelana nekhwalithi yomkhiqizo, izici, nezinga lokuqina ngenxa yezindinganiso.Bakhuthaza ukuphepha futhi bakhuthaze abakhiqizi ukuthi bakhe izimpahla ezisebenza kahle nezifeza amazinga athile okusebenza.Okubaluleke kakhulu, zisiza abasebenzisi ekwenzeni ukukhetha okunolwazi ukuze bakhethe izindawo ezivalekile ezifanelana nezidingo eziqondile zohlelo lwabo lokusebenza.
Kungaba nokwehluka okuningi ekuklanyweni nasekusebenzeni komkhiqizo ukube bezingekho izindinganiso eziqinile.Esikhundleni sokugxila ekutholeni inani eliphansi kakhulu, sikhuthaza bonke abathengi ukuthi bacabangele izindinganiso zomkhakha lapho bethola izindawo ezivalekile ezintsha.Ikhwalithi nokusebenza kubaluleke kakhulu kunezindleko zesikhathi eside.
Izidingo Zekhasimende
Ngenxa yokuthi abakhiqizi bendawo ebiyelwe kagesi badingeka kuphela ukufeza izidingo ezimbalwa (izindinganiso zabo), iningi lezidingo zokuvaleka zikagesi zivela kubathengi.Yiziphi izici amakhasimende azifunayo endaweni ebiyelwe kagesi?Iyini imicabango nezinkathazo zabo?Uma ufuna ikhabethe elisha elizobamba izinto zikagesi, yiziphi izici nezimfanelo okufanele uzibheke?
Cabangela lokhu okulandelayo lapho wenza uhlu lwakho lwezidingo nezintandokazi uma udinga indawo ebiyelwe ngogesi:
Izinto ezivalekile
Izivalo zenziwe ngezinto eziningi, okuhlanganisa insimbi, ipulasitiki, i-fiberglass, i-die-cast, nezinye.Cabangela isisindo, ukuzinza, izindleko, izinketho zokukhweza, ukubukeka, nokuqina kwezinketho zakho njengoba uzicwaninga.
Ukuvikelwa
Ngaphambi kokuthenga kwakho, bheka izilinganiso ze-NEMA, ezibonisa izinga lomkhiqizo lokuvikelwa kwemvelo.Ngenxa yokuthi lezi zilinganiso ngezinye izikhathi aziqondwa kahle, khuluma nomkhiqizi/umthengisi mayelana nezidingo zakho kusenesikhathi.Izilinganiso ze-NEMA zingakusiza ukuthi uthole ukuthi indawo ebiyelwe ifaneleka yini ukusetshenziswa ngaphakathi nangaphandle.kungakhathaliseki ukuthi ingakwazi ukuvikela ngokumelene nokungena kwamanzi, kungakhathaliseki ukuthi ingakwazi yini ukumelana nokwakheka kweqhwa, nokunye okuningi.
Ukukhweza kanye Orientation
Ukukhweza kanye Nokuqondisa: Ingabe indawo yakho ebiyelwe izofakwa odongeni noma ime ngokukhululekile?Ingabe indawo ebiyelwe izoqondiswa mpo noma ivundlile?Qiniseka ukuthi indawo ebiyelwe oyikhethayo ihlangabezana nalezi zidingo eziyisisekelo zokusebenza.
Usayizi
Ukukhetha usayizi ofanele wendawo ebiyelwe kungase kubonakale kuqondile, kodwa maningi amathuba.Uma unganakile, ungase "uthenge ngokweqile," uthenga indawo ebiyelwe kakhulu kunalokho oyidinga ngempela.Kodwa-ke, uma indawo yakho ebiyelwe ifakazela ukuthi incane kakhulu ngokuzayo, ungadinga ukuthuthukisa.Lokhu kuyiqiniso ikakhulukazi uma indawo yakho ebiyelwe izodinga ukwamukela intuthuko yezobuchwepheshe yesikhathi esizayo.
Ukulawula Isimo Sezulu
Ukushisa kwangaphakathi nangaphandle kokubili kungalimaza imishini kagesi, ngakho-ke ukulawula isimo sezulu kubalulekile.Kungase kudingeke ukuthi uphenye izindlela zokudlulisa ukushisa ngokusekelwe ekukhiqizeni ukushisa kwemishini yakho nendawo yayo yangaphandle.Kubalulekile ukukhetha isistimu yokupholisa efanele yendawo yakho ebiyelwe.
Isiphetho
Bheka i-Eabel Manufacturing uma ufuna inkampani engakhiqizela izivalo zensimbi ezinhle kakhulu egameni lakho.Izivalo zethu ezintsha, zekhwalithi ephezulu zisiza imboni yezokuxhumana ukuthi ithuthukise futhi ithuthukise ukunikezwa kwayo kwenethiwekhi.
Sinikeza uhlobo lwe-NEMA 1, uhlobo 2, uhlobo 3, uhlobo 3-R, uhlobo 3-X, uhlobo 4, kanye nohlobo lwezindawo ezivalekile zensimbi ezingu-4-X, ezenziwe nge-aluminium, insimbi eyakhiwe ngothayela, i-carbon steel, nensimbi engagqwali.Xhumana nathi, ukuze ufunde kabanzi, noma ucele ikhotheshini yamahhala ku-inthanethi.
