Pasin bilong makim ol kebol i save senisim sefti, reliabiliti na sevis laip bilong ol intanel waya bilong ol ilektronik ikwipmen, low-voltage DC transmisen bilong ol indastriel kar na ol otometik ikwipmen. UL Style 2726, o UL2726 tasol, em i wanpela multi-core Appliance Wiring Material (AWM) kebol we planti manmeri i save yusim long sampela aplikesen bikos em i liklik voltej, multi-core straksa na em i inap long tanim tanim.
UL 2726 Besik Spesifikesen na Straksa
UL Style 2726 (pablik infomesen olsem Specialty Cable Corp.) i tok, em i wanpela 'multi-conductor cable' wantaim wanpela 'extruded non-integral sheath':
-
Kondakta: Solid o stranded kopa kondakta (planti taim ol i save putim tin-plated o bare kopa stranded bilong mekim em i ken tantanim gut).
-
Insulation: Insulesen materiel we i bihainim AWM program bilong kampani o olsem ol i makim (planti taim PVC o ol wankain thermoplastic materiel).
-
Asembli: Tupela o moa kondukta, we ol i ken tanim i go long tupela o grup na bihain tanim wantaim; ol i ken stretim tu long paralel long kamapim wanpela 'flat', 'oval', o raunpela 'cable'. Ol i no makim stret 'strand pitch'. Ol i gat opsenel 'barrier layer' na 'filler'.
-
Shielding: Opsenel
-
'Overlay' (opsenel): Yu ken putim wanpela 6 mil o moa tik PVC 'overlay' i go antap long 'conductor assembly'.
-
Sheath: PVC, tiknes i senis wantaim ausait diamita bilong kebol (olsem, minimam averes 15 mils bilong ol ausait diamita Liklik o wankain olsem 0.250 ins, minimam 12 mils long wanem hap; ol bikpela ausait diamita i nidim bikpela tiknes).
Insait long ol prodak bilong mipela, mipela i putim ol narapela samting olsem VW-1 'vertical flame testing' na 'RoHS compliance', we i tok strong long bikpela 'flexibility', 'resistance' long 'mechanical stress', 'oil resistance', na 'chemical resistance', na dispela i mekim ol i gutpela long ol ples we i gat bikpela 'vibration' na 'shock'. Voltej we ol i makim em 30V, na tempereja em 60 digri, na dispela i mekim em i gutpela long ol 'low-voltage DC' aplikesen.
UL2726 em i bilong AWM kategori na em i bilong yusim insait long ol ikwipmen o long ol ples we i gat lukaut, na i no bilong yusim long ol waia bilong wokim haus o ol aplikesen we i gat bikpela voltej.
Skelim UL2726 wantaim ol narapela UL kebol
Long helpim wok bilong makim, tebol aninit i skelim ol bikpela samting bilong UL2726 wantaim sampela AWM o ol narapela kebol.

Olsem tebol i soim, UL2726 i gat liklik voltej na tempereja reiting, tasol fleksibel straksa bilong en i mekim em i gutpela long ol multi-core low-voltej senario;UL1007em i gutpela moa long ol 'single-core higher voltage internal wiring; UL 2464 i karamapim planti kain kain kontrol signal aplikesen; naUL20276em i planti taim ol i save yusim long ol robotik o ol hai-spid mobail aplikesen.

Ol aplikesen senario
Ol bikpela gutpela samting bilong UL2726 i stap long liklik voltej bilong en, planti-core, fleksibiliti, na opsenel shielding, na dispela i mekim em i gutpela long ol dispela samting:
Intenel waia bilong ol ilektronik ikwipmen: bilong intanel signal o low voltage pawa koneksen insait long ol instramen, daignostik ikwipmen, kontrol panel, na ol narapela samting bihainim ofisel nem bilong en.
② DC low-voltage transmission insait long ol indastrial kar (ol bateri pek insait long ol lektrik foklift, staka, palet trak na ol narapela samting i go long ol mota kontrola na draiv sistem) Planti taim ol i save kisim pawa long 24V/48V bateri sistem na i gat bikpela karent dro. Ol kebol we ol i yusim i mas sanap strong long benk, guria na bagarap.
Ol 'auxiliary system' insait long ol 'internal combustion engine engineal vehicles' • Ol i save yusim long ol 'starter battery', 'generator-' bateri koneksen, na ol 'auxiliary power lines' • Ol i nidim oil resistans na flame retardancy.
Ol Otometik Gaided Vehikel (AGV) na Otometik Mobail Robot (AMR) Konektim ol bateri kompatimen i go long ol draiv yunit, ol sensa na ol kontrol sistem insait long ol smat warehaus na ol semikondakta klinrum.
Ol narapela 'low-voltage scenarios: Ol i save yusim hap bilong data/signal transmisen o sot-distens koneksen namel long ol divais (ol i mas konfem olsem 'shielding' na 'impedance' i wankain).
Ol dispela aplikesen i tok strong long strong bilong masin, paia i no inap long paia, na strong bilong putim ol waya insait long ol spes we i no gat planti samting.
Ol keis bilong aplikesen
Kes Stadi 1: Elektrik Foklift Bateri-Motor Koneksen

Ol kebol i gat ol 'multi-strand stranded copper conductors na PVC insulation bilong strongim konduktiviti long taim bilong stat na stop planti taim, tanim na ol liklik rot namel long ol 'rack'. Ol i inapim tu ol sefti standet, bikos ol i bin winim wanpela tes bilong 'horizontal flame'. Ol i daunim mak bilong bagarap bilong ol ikwipmen na ol i mekim wok mentenens i go longpela taim bihain long ol i putim dispela samting, na dispela i soim olsem ol ikwipmen i gat gutpela samting long envairomen we i gat bikpela senis na bikpela 'current pulse'.
Kes Stadi 2: AGV/AMR Smat Fektri Diploimen
Insait long ol e-komes warehaus na ol woksop bilong wokim ol semikondakta, ol i save yusim ol UL2726 kebol long putim ol waia long ol bateri i go long ol draiv na kontrol modul insait long ol AGV na AMR. Ol kebol i gat bikpela 'flexibility' na 'mechanical stress' i save senis long ol kain kain samting olsem rot i bruk na 'emergency braking', tasol ol 'low-smoke, 'flame-'retardant samting bilong ol i save daunim hevi bilong paia insait long ol klinpela rum. Wanpela kampani i tok olsem bihain long ol i adoptim ol kebol we ol i wokim long laik bilong ol yet we i bihainim UL2726, wok bilong ol ikwipmen i kamap gutpela moa, na i inapim ol sefti na envairomen rikwaemen bilong fektori.
Kes Stadi 3: Ol Intenel Ikwipmen na Ol Instramen bilong Painimaut
Insait long ol medikel o indastriel daignostik ikwipmen, UL2726 i save yusim long intanel multi-signal low-voltej kebol. Ol opsenel 'shielded' vesen i helpim long daunim ol hevi, na ol 'extruded sheaths' i helpim wok bilong putim wantaim. Taim yumi skelim wantaim ol 'single-core' kebol, 'multi-core' integreted straksa i save daunim hevi bilong putim ol kebol na spes we i nidim.
Gutpela pasin bilong bungim ol pasin bilongUL2726long liklik volteji na bikpela fleksibiliti i soim bikpela inkris long sistem reliabiliti na sefti long ol kain keis olsem. Em i gutpela long mekim ol tes bilong 'current carrying capacity', 'bending life' na 'compatibility test' taim yu makim wanpela prodak, na sekim ol UL setifikesen pepa bilong dispela prodak.
Ol samting bilong makim na yusim
1. Mekim gut voltej (30V klas) na tempereja (60 digri) na noken winim ol spesifikesen.
2. Lukluk long 'conductor stranding' na 'sheath thickness' bilong 'mechanical life'.
3. Lukluk long ol prodak we i gat olgeta UL fail namba na ol narapela setifikesen olsem RoHS/VW-1.
4. Taim yu putim, lukluk gut long 'bending radius' bai i no gat 'over stretching' o 'compression'.
5. Long ol bikpela volteji o ol wok ausait, yusim ol narapela kain UL (olsem, ol kebol bilong wokim haus o ol kebol bilong trei).
Maski UL2726 em i no wanpela jenerel-pepos hai-pawa kebol, em i save mekim bikpela wok long ol ilektronik ikwipmen na ol indastriel low-voltej DC aplikesen. Taim ol i kliagut long ol spesifikesen bilong en, ol samting we i narapela long ol wankain prodak, na ol aplikesen bilong wol, ol yusa i ken yusim ol seif na gutpela rot bilong putim ol 'cabling'.
