Ikhebula le-H07RN-F: Isixazululo Samandla Esiqinile Nesiguquguqukayo Sezindawo Ezidinga Ugesi
Kuhlelo olukhulu lwezintambo zikagesi, lapho izimo ezithile zibeka khona izidingo eziqondile, ikhebula le-H07RN-F livelele njengethuluzi elisebenzayo lokuqina nokuguquguquka. Le khebula elihlanganisiwe, elichazwa yizindinganiso zaseYurophu, lenzelwe ukusebenza ngokwethembeka kwezinye zezindawo eziyinselele kakhulu, kusukela ezindaweni zokwakha kanye nezindawo zokusebenzela zezimboni kuya ekusetshenzisweni kwezolimo nasolwandle. Umklamo wayo ubeka phambili ukuqina, ukuphepha ngaphansi kokucindezeleka kwemishini, kanye nokusebenza okuqhubekayo ezimweni zezulu eziguquguqukayo, okwenza kube yitshe legumbi lokuphakelwa kukagesi oluphathekayo kanye nokufakwa okuhleliwe ezindaweni ezimanzi noma zangaphandle.
Ukunquma Igama: Ukuqonda Imininingwane
Isikhundla sezinombolo ezibhalwe ngamagama ahlukene "H07RN-F" asisho ukuthi sinobulungiswa; yikhodi emfushane eveza izici ezibalulekile zekhebula ngokwe-HD 22 ejwayelekile evumelanisiwe. S4:
H:Kusho ikhebula elivumelanisiwe, okusho ukuthi imininingwane yalo ijwayelekile kulo lonke elaseYurophu (CENELEC).
07:Kubonisa isilinganiso sama-voltage: 450/750 Volts. Lokhu kuchaza ukusetshenziswa kwawo kuma-voltage afinyelela ku-450V phakathi komqhubi nomhlaba, kanye nafinyelela ku-750V phakathi kwabaqhubi.
R:Kusho ukuthiukuvikela ukushisaizinto ezibonakalayoIrabha ye-Ethylene Propylene (EPR)noma uhlobo olufanayo lwerabha yokwenziwa.
N:Kusho ukuthiisikhwama sangaphandle (ijazi)yenziwe ngeIrabha ye-Chloroprene (Neoprene).
F:Lokhu kuyincazelo ebalulekile, okubonisa ukuthi ikhebula lineziciomqhubi bezintambo ezincane, abaguquguqukayo. Umqhubi ngamunye wakhiwe ngemicu eminingi emincane yethusi, okunikeza ikhebula ukuguquguquka okungavamile, okubalulekile ekusetshenzisweni okudinga ukunyakaza njalo, ukugoqa, kanye nokuvuleka.
Lo mkhuba wokuqamba amagama utshela onjiniyela kanye nochwepheshe bezogesi ngokushesha ngezakhiwo zikagesi eziyisisekelo zekhebula kanye nokwakhiwa okuqinile ngokomzimba.
Izici Eziyinhloko Nokwakhiwa
Ikhebula le-H07RN-F lakhiwe njengethangi, kanti ungqimba ngalunye lusebenza umsebenzi othile wokuvikela.
Umqhubi:Ingaphakathi lakhiwe ngezintambo zethusi ezithambile nezithambile. Inani elikhulu lezintambo liyimfihlo yokuguquguquka kwalo, okuvumela ukuthi likwazi ukumelana nokugoba okuqhubekayo nokusonteka ngaphandle kokuqina nokusebenza kanzima. Ama-conductor atholakala ezindaweni eziningi ezinqamula izinhlangothi, ngokuvamile kusukela ezincane njenge-0.75 mm² kuya ku-400 mm² noma ngaphezulu, ezihambisana namandla ahlukahlukene okuthwala ugesi.
Ukuvala:Umqhubi ngamunye ugqunywe ngesendlalelo se-insulationIrabha ye-Ethylene Propylene (EPR). I-EPR ikhethwa ngenxa yezakhiwo zayo zikagesi ezinhle kakhulu, ukuzinza kokushisa kwesikhathi eside, kanye nokumelana nokushisa, i-ozone, kanye nokuguquguquka kwesimo sezulu. Iqinisekisa ukuthi ama-conductors ahlala ehlukanisiwe ngisho noma ikhebula libhekene nokushintshashintsha kwezinga lokushisa.
Ukugcwalisa kanye Nokulala:Ezintanjeni ezinezinsika eziningi, izikhala eziphakathi kwezinsika ezivalekile zivame ukugcwaliswa ngezinto ezingezona ezi-hygroscopic (njengerabha noma indwangu). Lokhu kunikeza intambo isimo esiyindilinga nesincane. Isendlalelo sombhede singafakwa phezu kwezinsika ezibekwe ukuze kuhlanganiswe futhi kuvikelwe okwengeziwe.
Isigqoko (Ijazi):Ingqimba engaphandle kakhulu iyisivikelo esichazayo se-H07RN-F: aIrabha ye-Chloroprene (Neoprene)isigqoko. Le nto iqinile kakhulu, inikeza ukumelana okuvelele ku:
Ukusetshenziswa Kabi Kwemishini:Ukuguguleka, ukuchoboza, ukushayisana, kanye nokusikeka.
Ukucindezeleka Kwemvelo:I-ozone, ukukhanya kwelanga (imisebe ye-UV), kanye nobubanzi obuhlukahlukene bamazinga okushisa (ngokuvamile kusukela ku--25°C kuya ku-+60°C ezindaweni ezihlala isikhathi eside, kanye nokwehla kuya ku--40°C ukuze kusetshenziswe kalula).
Amakhemikhali Namafutha:Iyamelana nokuwohloka okuvela kumafutha, amafutha, ama-asidi, ama-alkali, kanye namanzi olwandle ngezinga elikhulu.
Ukusabalala Kwamalangabi:Isigqoko sivimbela ilangabi (sihlolwe ngokwe-EN 60332-1-2), sinciphisa ukusabalala komlilo.
Ikhebula ngokuvamile limnyama, lineziqondisi ezinemibala (isb., onsundu, oluhlaza okwesibhakabhaka, omnyama, ompunga, oluhlaza/ophuzi womhlaba) ukuze kube lula ukulibona ngesikhathi sokufakwa.
Imininingwane Yobuchwepheshe Ngokushesha
Amazinga:Ihambisana ne-HD 22.14, i-BS EN 50525-2-21, kanye ne-VDE 0282-14.
Isilinganiso se-Voltage:U₀/U 450/750 V.
Ibanga Lokushisa:
Ukufakwa okugxilile: -25°C kuya ku-+60°C
Isevisi eguquguqukayo: -40°C kuya ku-+60°C
Irediyasi Egobayo:Irediyasi encane yokugoba enconywayo ngokuvamile iphindwe kasithupha kunobubanzi bekhebula iyonke ekufakweni okuzinzile kanye nezikhathi ezi-5 zokusetshenziswa okuguquguqukayo, okugqamisa ukuguquguquka kwayo.
Ukucushwa Okuyinhloko:Itholakala ngezindlela ezahlukene zokucushwa: i-2-core (enomhlaba), i-3-core, i-4-core, kanye ne-5-core, kanye nezinguqulo ezine-concentric earth/neutral conductor.
Izimo Zokusebenza Eziyinhloko
Inhlanganisela yokuguquguquka, ukumelana nesimo sezulu, kanye nokuqina komshini inquma izimo ezifanele zokusetshenziswa kwezintambo ze-H07RN-F:
Izindawo Zokwakha Nokufakwa Kwesikhashana:Kuyinto ebaluleke kakhuluikhebula lokunikeza indawongamathuluzi okukhanyisa, imibhoshongo yokukhanyisa, kanye nezindlu zasendaweni. Ukuqina kwayo kuvikela ekulimaleni okuvela ematsheni, ekuhuduleni, nasekuchayekeni kwesimo sezulu.
Imishini Yezimboni Nezindawo Zokusebenzela:Isetshenziselwa ukuxhuma imishini ephathekayo esindayo, imishini yokushisela, kanye nemigqa yokuhlanganisa lapho kukhona khona uwoyela, amafutha, kanye nokunyakaza okuqhubekayo.
Umkhakha Wezolimo:Ilungele imishini yasepulazini, izinhlelo zokunisela, kanye nokufakwa kwezibaya, njengoba imelana nomswakama, indle yezilwane, umanyolo kanye nokukhanya kwelanga.
Izindawo Zasolwandle Nasogwini:Ivame ukusetshenziswa emachwebeni, ezindaweni zokupaka imikhumbi, kanye nasekuhlinzekeni ugesi emikhunjini (amandla ogwini), ngenxa yokumelana kwayo namanzi anosawoti, i-ozone, kanye nezimo ezimanzi.
Imboni Yemicimbi Nokuzijabulisa:Inika amandla iziteji zangaphandle, izinkundla zemikhosi, kanye nokufakwa kwesikhashana lapho izintambo zifakwa khona phansi futhi zingaphansi kwethrafikhi yabahamba ngezinyawo.
Ukumba kanye nokumba:Ekusebenzeni kobuso, ukuqina kwayo kuyenza ifanelekele ugesi wemishini yokumba, imishini yokugugula, kanye neminye imishini yezimboni ezihambayo.
Ukufakwa Kwangaphandle Okungaguquki:Ukuze kufakwe izintambo ezihlala njalo ezingadini, eziteshini zokupompa, noma ezinhlelweni zokukhanyisa zangaphandle lapho kudingeka khona ukungcwatshwa okuqondile noma ukuchayeka elangeni (yize ukungcwatshwa okuqondile ngaphandle komsele kungadinga ukuqinisekiswa okwengeziwe).
