Insait long waia na kebol indastri, UL setifikesen em i nambawan mak bilong kwaliti insait long maket bilong Not Amerika na ol bikpela aplikesen long wol. NaXLPE, 'cross-linked polyethylene', em i nambawan samting bilong mekim wok bilong pasim san. Tenkyu long gutpela wok bilong 'cross-linking proses, em i go-long solusen bilong namel na bikpela volteji, na tu long hai-temperature envairomen.XLPE i kamapim wanpela 3D netwok molekiul straksa long rot bilong kemikel o fisikel kros-linking. Taim yumi skelim wantaim ol tumbuna PE materiel, em i bikpela step antap long hat, strong bilong masin na lektrik insulesen. Em inap wok long wanpela stedi tempereja bilong 90~150 digri, na tu em i no gat planti smok, i no gat halogen, i no inap paia na i no bagarapim envairomen. Dispela i mekim em i gutpela tru long planti kain nid long eneji stoa, ol indastrial ikwipmen, ol samting bilong haus na moa. Nau, mipela bai lukluk long 4-pela UL waia model bilong ol faktori bilong mipela wantaim XLPE insulesen –UL3817, UL3271, UL3321naUL3289– na brukim daun ol bikpela teknikel samting bilong ol na ol samting we i gutpela long en.
Bikpela samting bilong XLPE insulesen: Bilong wanem em i gutpela samting bilong putim long ol 'high-end wiring?
Ol gutpela samting bilong XLPE i kam long bikpela wok bilong "kros-linking". Taim ol i brukim ol 'linear molecular chains' bilong 'polyethylene' na kamapim ol 'bridge bond', em i senis long wanpela "linear straksa" i go long wanpela "netwok straksa", na dispela i kamapim wanpela bikpela apgret long pefomens: Namba wan, hat resistans i kamap bikpela tru. Longpela taim wok tempereja bilong nomol PE em 70 digri tasol, tasol XLPE inap long sanap strong long wok i go het long 90 digri - 150 digri, wantaim sotpela taim ovalod tempereja inap long 130 digri, na em inap sanap strong long 250 digri long taim bilong sot seket; Namba tu, wok bilong pawa i gutpela tru, wantaim bikpela insulesen resistans na liklik 'dielectric loss', we i gutpela long ol 'medium' na 'high voltage' senario, na insulesen leia i wankain na isi long rausim, na dispela i helpim wok konstraksen na instolesen; Namba tri, envairomen adaptability em i strongpela, i no inap long kisim oil, asid na alkali, i no inap long bagarap long ol masin, na sapos i no gat halogen, em i no inap long paia na i no save kamapim ol 'toxic halogen-gas insait long en taim em i kukim, na dispela i inapim ol RoHS envairomen standet, na dispela i givim taim long ol wokmanmeri long lusim ples na lukautim ol ikwipmen. Dispela bung bilong ol samting i mekim na ol XLPE insulated UL waia em i nambawan samting bilong senisim ol PVC kebol na stretim ol long ol bikpela samting.
Gutpela tok klia long 4-pela bikpela model: Pefomens Diferensiesen i kamap long ol narapela narapela samting
UL3817: Wanpela strongpela hai-voltej Adapta bilong Eneji Stoa Sistem
UL3817 em i wanpela XLPE-insulated waia we ol i wokim bilong ol namel na bikpela voltej, wantaim wanpela 'temperature' bilong 125 digri na wanpela 'AC voltage' bilong 3000V - em i gutpela tru long ol strongpela hai-voltej na hai-temperature rikwaemen bilong ol strongpela sistem bilong putim eneji. i stap long tin kopa/bare kopa, na 'insulation layer' em i XLPE samting. Em i winim tupela UL horisontel na CSA FT2 vertikal flamabiliti tes, olsem na em i gat tupela samting, flame retardancy na eco-friendliness i karamapim. Long sait bilong straksa, UL3817 i gat wanpela yunifom tikpela insulesen leia, na em i stap long ol waia gej stat long AWG 30 olgeta i go inap long 40/4, wantaim diamita stat long 15 anta. 19.00mm. Yu ken makim stretpela kain bihainim spes we ol masin bilong yu long putim eneji i nidim. Long ril-wol yus,UL3817em i save yusim moa yet long ol koneksen long DC sait bilong ol sistem bilong putim lektrik eneji – namel long ol bateri modul, ol bateri klasta, na tu namel long ol bateri klasta na ol kombaina bokis na tu ol PCS. Wantaim gutpela wok bilong en long sait bilong lektrik na ol samting we i no gat planti smok long en, em i save mekim bikpela wok long ol bikpela pawa stesin na ol masin bilong putim pawa long ol haus. Em i save stopim gut ol insulesen long kamap lapun aninit long bikpela hat na bikpela voltej, na i save mekim wok bilong olgeta eneji stoa sistem i wok gut.
UL3271: Em i wanpela gutpela pilaia bilong ol jenerel indastrial senario
UL3271 em i wanpela gutpela XLPE-insulet waia wantaim wanpela 'rated voltage' bilong 600V na wanpela 'operating temperature range' namel long -40 digri i go inap 125 digri. Em i wok gut tru long ol 'fixed instolation' na ol 'low-'moving aplikesen, na dispela i mekim em i gutpela samting bilong putim ol waya insait long ol indastrial ikwipmen. Kondakta bilong en em i 'bare copper' we i inapim IEC 60228 Klas 5 standet, na 'cross-linked insulation layer' i save givim gutpela kemikel resistens - em inap long sanap strong long ol asid, alkali na sampela kain gris. Em i save winim tu ol tes bilong pasim paia, olsem na em i inapim ol sefti rikwaemen bilong ol indastrial envairomen. Taim yumi toktok long ol aplikesen,UL3271em ol i save yusim long ol 'motor leads', 'transformer', 'distribution panel' na 'internal wiring' insait long ol samting bilong haus. Maski em i ol kontrol modul long ol otometik prodaksen lain o ol lektrik koneksen long ol komyunikesen ikwipmen, gutpela wok bilong en i save daunim ol taim we i no gat plen long en we i save kamap bikos long ol asua. Antap long dispela, dispela model i ken kamap long kain kain standet kala, we i mekim isi long luksave long ol narapela narapela signal taim yu putim waya. Minimum 'bending radius' bilong en em 4-pela taims tasol long 'cable diameter' bilong ol 'fixed installations', olsem na em i gutpela tru long putim long ol liklik na kompleks spes.
UL3321: Spesel wiring Solusen bilong ol hai-temperature bilong ol haus samting
UL3321 em i wanpela we i gat bikpela 'heat resistance rating' namel long ol dispela 4-pela model - em i gat 'temperature' inap long 150 digri na 'voltage' bilong 600V, na ol i wokim stret long ol haus na indastrial ikwipmen we i wok long ol ples we i gat bikpela hat. Em i yusim ol 'stranded tinned copper conductors' wantaim wanpela 'XLPE insulation layer', we i gat gutpela 'flame retardancy' na 'melt resistance'. Em inap long ron gut insait long ol samting bilong haus we i gat bikpela hat olsem aven, hita na draia, na em i ken sanap strong long ol bikpela hat we i save kamap taim ol i yusim ol dispela masin na stopim 'insulation layer' long kamap malumalum o bruk. Long sait bilong teknikel, UL3321 i gat setifiket long UL758 na UL1581 standet, na em i inapim ol RoHS na Low Voltage Directive rikwaemen. Test voltej bilong en inap long kamap 2000V i go inap 3500V bihainim 'wire gauge', olsem na 'insulation reliability' bilong en i nambawan tru. Antap long ol samting bilong haus we i gat bikpela hat, dispela model em ol i save yusim tu long putim ol waia insait long ol indastrial ikwipmen olsem ol indastrial hita na ol aven we i gat bikpela hat. Maski aninit long tupela hatpela kondisen bilong bikpela tempereja na bikpela voltej, em inap long holim yet gutpela wok bilong pawa na strong bilong masin.
UL3289: Hai-temperature i stret long ol wok bilong masin na ol samting bilong haus
UL3289 i save givim pefomens wankain olsem UL3321, na ol bikpela strong bilong en i stap long ol gutpela 'mechanical properties' na 'flame retardancy' bilong en. XLPE insulation layer bilong en i gat spesel tritmen long en we i no inap bagarap na i no inap bagarap – em bai no inap bagarap hariap long ol taim we ol ikwipmen i save guria planti o i save muv planti taim. Em i inapim tu IEC 60332-1-2 FT2 'flame retardant' standet, wantaim strongpela 'self-extingushing' samting na liklik smok taim em i stap long paia. Taim yumi laik yusim,UL3289em i save kamap planti taim long ol 'motor leads', ol 'internal wiring' insait long ol samting bilong haus, na ol 'electrical connection' insait long ol masin bilong indastri. Em i gutpela tru long ol taim we i nidim bikpela hat na gutpela mekanikel stebiliti, olsem ol bikpela masin bilong wasim klos na ol masin bilong karim ol samting i wok long ples we i gat bikpela hat. Skelim wantaimUL3321, tupela model i gat wankain 'high-'tempereja pefomens. Yu ken makim namel long ol bihainim ol spesifik mekanik rikwaemen bilong ikwipmen bilong yu na baset bilong yu.
