Ukukhethwa kwekhebula kubalulekile kwizixhobo ze-elektroniki kwi-wiring yangaphakathi, ulawulo oluzenzekelayo lwemizi-mveliso kunye nokuhanjiswa komqondiso wedatha. I-UL20276 yinto eqhelekileyo UL-eqinisekisiweyo kaninzi-intambo yesiginali engundoqo esetyenziswa kwizixhobo zombane ezininzi kunye neenkqubo zolawulo, ngenxa yokukhanya kwayo, ukuguquguquka kunye nokuthobela umgangatho wokhuseleko.
Yintoni intambo ye-UL20276?
UL20276 luninzi-isimbo sentambo engundoqo ngaphakathi kwe-UL 758 Appliance Wiring Material (AWM) series. Multi-intambo yeconductor ene extruded, non{5}}integral sheath. Ilinganiswe ngokubanzi nge-30V, kunye neqondo lobushushu le-60 okanye i-80 degrees C. Idibene ne-UL VW- 1 uvavanyo lokutshisa oluthe nkqo, ebonisa iimpawu ezilungileyo zokubuyiswa komlilo. IIKHONIKI ZIQHELEKILEYO zezobhedu olutotiweyo. I-insulation kunye ne-sheath ngokubanzi ziyi-PVC. Ezinye zinealuminiyam yokuzikhethela{16}}ikhuselo lefoyile, isikhuselo esiphothiweyo okanye isikhuselo esijijekileyo.
I-UL20276 inokwakhiwa ngeekondaktari ezigqunyiweyo ezimbini okanye ngaphezulu ezijijelwe ngababini okanye zidityaniswe ngokwamaqela ngokunxuseneyo. I-sheath yi-PVC, ikhutshwe, kunye nokukhusela okukhethiweyo. I-RoHS kunye nezinye izinto ezihambelana nokusingqongileyo kwaye zifanelekile kwi-wiring yangaphakathi okanye ukudibanisa kwangaphandle kwezixhobo ze-elektroniki kwiisekethe ze-Class 2. Ulwakhiwo oluqhelekileyo Iziqhubi zekopolo ezinkonkxiweyo I-PVC yokugquma iAluminiyam{5}}itheyiphu ehlanganisiweyo yeplastiki + inkonkqo yobhedu olulukiweyo isikhuselo (ukhetho) I-PVC yangaphandle yesingxobo Iradiyasi yokugoba idla ngokuba ngamaxesha angama-6-10 (omisiweyo) okanye amaxesha ayi-8-20 (ehambayo) ububanzi bentambo.
Iimeko zesicelo eziphambili ze-UL20276
UL20276Amandla ombane aphantsi kunye -noguquko olungundoqo luyenza ilungele umqondiso kunye nolawulo lwezicelo, kunokuba{1}}ugqithiso lwamandla aphezulu.
Izicelo eziphambili ziquka:
-
Iingcingo zangaphakathi zezixhobo zombane: Iikhompyutha, iiperipherals, iilaptops, iLCD/LED iintambo zokubonisa, iintambo zescanner, njl
-
Ugqithiso lwedatha kunye nomqondiso: Iintambo zedatha kumatshini kunye nezixhobo zokutshitsha, ngakumbi apho kuphezulu kufutshane-ukunciphisa i-crosstalk kufuneka. I-twisted{{2}isibini + iinguqulelo ezikhuselwe ngefoyile nganye zifanelekile kumazinga aphezulu othumelo lwedatha.
-
I-Automation ye-Industrial automation kunye ne-robotics: Iindawo ezihambayo kwi-automation ye-factory (FA), iintambo zerobhothi, iinkqubo zokuthwala iintambo. Ezinye iinguqulelo eziguquguqukayo kakhulu zinokumelana ne-50 yezigidi ukuya kwi-100 yezigidi zovavanyo lokugoba.
-
Iinkqubo zokulawula kunye nokubeka iliso: Iisekethe zokulawula ezihlakaniphile, izixhobo zokulawula ubushushu, iinkqubo zokulawula i-HVAC, iinkqubo zokubeka iliso zokhuseleko, i-automation ye-ofisi, kunye ne-wiring yangaphakathi yezixhobo zasekhaya.
-
Ihlawulela ulungelelwaniso olugwenxa kunye nokuphambuka
-
Abanye: Izixhobo zokulinganisa kunye nokuvavanya, uqhagamshelo lwangaphakathi lweenkqubo ezipheleleyo zezixhobo.
Kwezi zicelo, iintambo zihlala zisetyenziswa kwindawo ezomileyo okanye ezifumileyo zangaphakathi zangaphakathi, nokuba zilungisiwe okanye zihamba kancinci. I-30V yayo yombane inciphisa ngokucacileyo ukusetyenziswa kwayo -kusetyenziso lwamandla aphezulu.
Ukuthelekisa UL20276 kunye -nocingo olungundoqo olulodwa
Olunye- ucingo olungundoqo (omnye-omnye{1}}ongundoqo ogqunyiweyo) ubhekisa kwikhondaktha enye eqinileyo okanye exineneyo egqunywe ngomaleko wokugquma, ngaphandle kwesingxobo esidityanisiweyo okanye{2}}isiseko esidityanisiweyo. Imizekelo eqhelekileyo iquka i-AWM eyodwa{4}}iingcingo ezingundoqo ezifanaUL1007kwayeUL1015, ngee-voltages ezilinganisiweyo ubukhulu becala kwi-300V okanye i-600V, ilungele umbane okanye iingcingo ezisisigxina. UL20276, kwelinye icala, yintambo eqhelekileyo-engundoqo enesheathed. Ezi zimbini zahluke kakhulu kulwakhiwo, ukusebenza kunye nokusetyenziswa.
Le theyibhile ilandelayo ithelekisa imilinganiselo engundoqo:

Intambo enye yeempawu ezininzi igcina indawo kunye nexesha locingo |
Iisekethe ezininzi zifuna iingcingo ezininzi, okwenza i-wiring complex, kodwa ukutshatyalaliswa kobushushu kungcono |
| Usetyenziso oluqhelekileyo | Iimpawu zangaphakathi ze-elektroniki, idatha, ulawulo, ukutsala amatyathanga | Iingcingo zombane ezilungisiweyo,{0}}uqhagamshelwano oluphezulu lwangoku ngaphakathi kwendawo yolawulo |
| Iindleko | Iphezulu kakhulu (ezininzi-ezingundoqo + inkqubo yesheath) | Iphantsi ngokwentelekiso |
Njengoko sibona kuthelekiso,{0}}iingcingo ezingundoqo ezine-advanteji zesakhono sokuthwala esomeleleyo sangoku kunye nofakelo olusisigxina, ukulahla ubushushu okulungileyo kunye neendleko eziphantsi, ezilungele{1}}umbane omgama okanye ukusetyenziswa kwangoku okuphezulu. Kodwa, ukuba ufuna ukuthumela iisignali ezininzi ngexesha elinye, okanye isithuba sikwiprimiyamu, okanye ufuna ukugoba intambo, okanye kufuneka uyikhusele ekuphazamisekeni, emva koko iintambo ezininzi{3}ezingundoqo, ezifana nezo zigqunywe yi-UL20276, ziphuma ngokucacileyo phezulu. Iingcingo enye-ezingundoqo ezisetyenziselwa imiqondiso emininzi zifuna ukudityaniswa okuthe kratya kunye nokukhuselwa, nto leyo eyongeza ukuntsokotha kunye neendawo ezininzi ezinokungaphumeleli. Iintambo ezininzi{8}ezingundoqo zibonelela ngesisombululo esifanayo, kunye neenzuzo ezisebenzayo, ngakumbi kwizixhobo ezizenzekelayo kunye nombane wabathengi.
Iingcebiso zokukhetha kunye nezilumkiso
Xa ukhetha i-UL20276, kuyafuneka ukuqinisekisa ukucaciswa kwe-AWG ethile, ukubala okungundoqo, nokuba ukhuselo luyafuneka, umlinganiselo wobushushu, kunye nokuba -inguqulelo yentambo yentambo ebhetyebhetye iyafuneka. Qaphela umda wayo we-30V; mayingaze isetyenziswe kwiisekethe zamandla eziphambili. Ngexesha lofakelo, bambelela kwi-radius yokugoba kwaye ugweme ukunweba ngokugqithiseleyo. Xa uyisebenzisa -ngocingo olungundoqo olunye, qinisekisa ukuhambelana kombane wenkqubo iyonke kunye nokumisa/ukukhusela.
Kwiiprojekthi zokwenyani, ukuba ikhebhuli yenzelwe ulawulo lomqondiso kunye nendawo elinganiselweyo,UL20276ikhethwayo; ukuba ugqithiso lwamandla okanye olulungisiweyo oluphezulu{0}}usetyenziso lwangoku lujoliso oluphambili, olunye{1}} ucingo olungundoqo lufanelekile ngakumbi. Umzi-mveliso wethu ubonelela ngeendlela zokubala ezingundoqo kunye neendlela zokukhusela ukuhlangabezana neemfuno ezithile ze-EMC.
Isishwankathelo
I-UL20276 yi-30V evuthiweyo emininzi -intambo yesiginali engundoqo enesatifikethi se-UL kunye ne-VW{5}}1 i-flame retardancy, i-flexible structure kunye nokukhusela okukhethiweyo, idlala indima ebalulekileyo kwi-wiring yezixhobo ze-elektroniki, ukuhanjiswa kwedatha kunye nokulawulwa kwe-industrial automation. Ingcono kune-iintambo ezingundoqo zodityaniso{7}}zemiqondiso emininzi kunye nosetyenziso oluphathwayo kodwa kungcono kwizicelo zamandla ezilungisiweyo{10}}ezinye ezingundoqo. Ukukhethwa okufanelekileyo kwandisa ukuthembeka kwenkqubo, kwandisa i-wiring kwaye ihlangabezane neemfuno zokhuseleko kunye nokuthotyelwa kokusingqongileyo. Kwisicelo esisebenzayo, kucetyiswa ukuba ubhekiselele kwidatha yedatha yomenzi kwaye ujonge ikhebula ngokuhambelana nombane, ubushushu, ukugoba kunye nokuphazamiseka kwendawo yeprojekthi, ukuze kufezekiswe ukusebenza okuzinzileyo kwexesha elide.
