Futhi kusho ukuzibophezela ngesikhathi sokulethwa okungokoqobo nokuxhumana ngokweqiniso lapho uhlelo lushintsha, ngoba ikhebula le-riser elibambezelile lingamisa sonke isitezi ukuthi singatholi amandla. Abathengi kufanele baqinisekise ama-Incoterms, incazelo yokupakisha, izidingo zokumaka kanye namadokhumenti adingekayo endaweni yokufika ngaphambi kokuba i-oda liqedwe. Ukubuyekeza isipiliyoni sephrojekthi yangaphambilini kuyindlela ewusizo yokuhlola, futhi i-AMACALAikhasi likhombisa umsebenzi oqediwe okuhlanganisa umugqa wokudlulisa ugesi, isiteshi sokukhulisa amandla, kanye namaphrojekthi okufakwa kukagesi wasemakhaya nelanga. Kuhlangene nokuhlelwa kwemikhiqizo ekhasini le-IMIKHIQIZOikhasi kanye nokubuyekezwa okuqhubekayo ku-Izindabaisigaba, lokhu kunikeza abathengi isithombe esisebenzayo samakhono ngaphambi kokuba bacele isilinganiso sentengo.

I-YJV isebenzisa izintambo zethusi kuyilapho i-YJLV isebenzisa izintambo ze-aluminium; zombili zine-insulation ye-XLPE kanye ne-sheath ye-PVC futhi zombili zisetshenziselwa ukusabalalisa amandla kagesi aphansi. Ithusi linikeza ukumelana nokugeleza kukagesi okuphansi, ukuxhuma okulula kanye nokusebenza okungcono emizileni emifushane enokugeleza kukagesi okuphezulu, kuyilapho i-aluminium inciphisa isisindo kanye nezindleko ngemitha futhi ifanele imizila emide lapho ububanzi obukhulu bungamukeleka. Ukukhetha kufanele kulandele incazelo yephrojekthi, amakhono okuxhuma atholakalayo kanye nephrofayili yomthwalo hhayi intengo kuphela.

I-BV iwucingo oluqinile lwe-single-core PVC insulated wire yokuxhuma okungaguquki kwi-conduit, i-RV iwucingo oluguquguqukayo lwe-single-core wire yokuxhuma kwephaneli nezinto zikagesi ezidinga ukugoba, kanti i-RVS iwukwakheka okuguquguqukayo okusontekile kwama-core amabili okwamalambu alengayo nezintambo zezinto zikagesi ezincane. Khetha i-BV lapho ukuxhuma kungaguquki futhi kuhlolwa, i-RV lapho ukuguquguquka nezindawo ezincane zokuxhuma zibalulekile, kanti i-RVS lapho ukwakheka kwe-twisted pair kulula. Akukho kuzo okuthatha indawo yekhebula likagesi eline-sheath ohlelweni lokusabalalisa.

Qala ngomthamo wokuklama, sebenzisa izici zokulungisa zezinga lokushisa lendawo, ukuhlanganisa, ukujula kokungcwaba kanye nokufakwa kwesibaya, bese ukhetha idivayisi yokuvikela futhi uqinisekise ukuthi umthamo olungisiwe wekhebula udlula isidingo. Hlola ukwehla kwe-volt ngokwehlukana emizileni emide, futhi uqinisekise ukumelana nesifunda esifushane somqhubi nesikrini. Ekugcineni, qinisekisa noma yiziphi izigaba ezincane eziphakanyisiwe zokuxhumana ezibekwe yisicaciso sephrojekthi ukuze kuqineke ngomshini noma ukukhula komthwalo esikhathini esizayo.

Yebo. Izicaciso zokwezifiso zihlanganisa into yomqhubi nokugoqwa, isigaba sokuxhumana, izinhlanganisela zokuvikela kanye nezeshethi, inani lomnyombo, izikhali, ukufakwa kwemibala, ubude bedramu, ukuphrinta nokupakisha, kanye nezinhlobo ezivimbela umlilo kanye nentuthu encane engu-zero halogen. Ama-oda e-OEM anegama lomthengi kumadramu nokuphrinta kweshethi nawo ayasekelwa. Ukwabelana ngendlela yokufaka kanye nezinga elihlosiwe ngesicelo kusheshisa ukuqinisekiswa komdwebo.

Yebo, amasampula amahhala anikezwa ukuze abathengi baqinisekise ukumelana kwabahambi, ubukhulu, ukujiya kodonga lwe-insulation kanye nokumaka ngaphambi kokuzibophezela ku-oda elikhulu. Ukuhlolwa kwesampula elabhu yesayensi ezimele kuyindlela ethembeke kakhulu yokuqinisekisa ukuthi umkhiqizo olethiwe uhambisana nedatha yayo. Ukuhlolwa kwesampula kufanele kwenzeke ngaphambi kokuba ukukhiqizwa kuqale, hhayi ngemva kokuba i-container isithunyiwe.

Encazelweni, igama elithi ikhebula lamandla ngokuvamile lisho inhlanganisela ehlanganisiwe yombhoshongo oyedwa noma ngaphezulu ahlukanisiwe anezigcwalisi, isibopho kanye ne-oversheath, elinganiselwe amandla kagesi wesistimu futhi elihloselwe ukudluliswa kwamandla. Lihlukile kucingo lokwakha, okuwumbhoshongo oyedwa ohlukanisiwe wokufakwa kwepayipi, kanye nekhebula lokulawula, elithwala amasignali esikhundleni samandla. Ukuqinisekisa ukuthi yisiphi isigaba esidingwa uhlelo lokuhlela kuvimbela iphutha elivame kakhulu lokuhlela.

Lindela izivivinyo zikagesi ezijwayelekile ezihlanganisa ukumelana komqhubi, ukumelana kwe-insulation kanye nesivivinyo sokumelana namandla kagesi aphezulu, kanye nokulinganisa kokukhishwa okuyingxenye kwekhebula lamandla aphakathi nendawo. Ukuhlolwa kwemishini nobukhulu kufanele kuhlanganise amandla okudonsa, ukunwebeka, ukujiya kodonga kanye nobubanzi obuphelele, kanye nemiphumela yokusabalala komlilo lapho umkhiqizo udinga khona. Izitifiketi zokuhlolwa kufanele zilandelwe zifinyelele ezinombolweni zamagquma ezilethiwe.

I-XLPE imelana nezinga lokushisa eliphezulu lomqhubi oqhubekayo futhi inikeza ukulahlekelwa kwe-dielectric okuphansi, ngakho-ke ikhethwa kakhulu ekusabalaliseni amandla kanye nomsebenzi wamandla aphakathi nendawo. Ukuhlukanisa kwe-PVC kwanele ezintanjeni eziningi zokwakha kanye nasekusetshenzisweni okulula futhi kubiza kancane, kodwa kunomkhawulo ophansi wokushisa. Ukukhetha okulungile kuncike emthwalweni, imvelo, isu lomlilo kanye nezinga elibhekiselwa kulo iphrojekthi.

Ukufakwa ngqo emhlabathini nokufakwa ngaphandle kuyenzeka uma ukwakheka kwekhebula kuhambisana nemvelo, okusho ngokuvamile ukuthi kufanele kube ne-armour, isivikelo somswakama kanye ne-sheath emelana ne-UV, kufakwe ekujuleni okufanele ngokulala kwesihlabathi kanye ne-tape yokuxwayisa. Ukuhlanganiswa kanye nokumelana nokushisa kwenhlabathi kunciphisa amandla okuthwala ugesi, ngakho ukufakwa emhlabathini kudinga ukubalwa kwayo kokunciphisa amandla. Ikhebula langaphakathi elingenayo i-armour akufanele livele lifakwe emhlabathini ngaphandle kokubuyekezwa kwencazelo.

Isikhathi sokuhola sincike emndenini womkhiqizo, inani, ukwenziwa ngendlela oyifunayo kanye nobude bamagilamfu, futhi kufanele kuqinisekiswe ngokubhaliwe nesilinganiso sentengo esikhundleni sokucatshangelwa. Ukuthunyelwa okuhlelwe ngezigaba kungahlelwa ukuze kuhambisane nezigaba zokwakha, futhi ukulayishwa kwamakhonteyina ahlanganisiwe kuyenzeka kumaphrojekthi adinga izinhlobo eziningi zamakhebula. Ukuqinisekisa i-Incoterms, izimpawu zokupakisha kanye namadokhumenti endawo kusenesikhathi kugwema ukubambezeleka kokukhishwa.

Xhumana ne-Yunnan Zhongqi Cable Co., Ltd. ngohlu lwamakhebula noma uhlu olulula lwezidingo, futhi ithimba lobuchwepheshe lizohambisa umugqa ngamunye nokwakhiwa okufanele futhi liqinisekise ukutholakala, isikhathi sokuhola kanye nentengo eqondile yasefektri. Ulwazi olusizo okufanele lufakwe kumyalezo wokuqala i-voltage yesistimu, into yomqhubi kanye ne-cross-section, inani le-core, izinga elidingekayo, indlela yokufaka kanye nenani elilindelekile, kanye nanoma yiziphi izidingo ezithile zeprojekthi zomlilo noma ze-sheath. Abathengi abasacubungula izinketho bangacela amasampula amahhala ukuze bahlole futhi baqinisekise ukumelana komqhubi kanye nobukhulu ngokuzimela ngaphambi kokuba i-oda elikhulu likhishwe. Imininingwane yangokwezifiso kanye ne-OEM branding kungaxoxwa ngayo esigabeni esifanayo, okugwema ukuphinda kucashunwe intengo kamuva enqubeni. Noma ngabe ufike lapha ufuna i-datasheet yekhebula lamandla noma uthayiphe okuhlukile okuvamile "power cabie" ngenkathi ufuna izinketho zomhlinzeki, isinyathelo esilandelayo esisebenzayo siyafana: yabelana ngesidingo, hlola isampula, futhi uqinisekise imininingwane ngokubhala ngaphambi kokuba ukukhiqiza kuqale. Lokho kulandelana kugcina amaphrojekthi okwakha nobunjiniyela esimisweni, kugcina imibhalo yokuhlola iphelele, futhi kugcina inethiwekhi efakiwe ithembekile emashumini eminyaka okufanele isebenze.
