Kusarudzwa kwewaya uye tambo mukugadzirwa kwemagetsi emazuva ano uye midziyo yemagetsi yakanangana nekuchengetedzwa kwechigadzirwa, kuvimbika uye kutevedzera mutemo. UL1672 chiyero kubva kuUnderwriters Laboratories (UL) yeAppliance Wiring Material (AWM) uye chinhu chakakosha mukushandiswa kwewaya dzemukati. Ichi chinyorwa chinopa sumo yakadzama kune UL1672 waya yakavakirwa paiyo chaiyo tekinoroji paramita uye maindasitiri maitiro, anosanganisira parameters, chimiro, mabhenefiti ekuita uye mamiriro ekushandisa, uye enzanisa nemamwe mazinga eUL, kuitira kuti mainjiniya, vashandi vekutenga uye vanofarira zvemagetsi vanzwisise zviri nani iyi mhando yewaya inoshandiswa zvakanyanya.
Mhedziso yeiyo UL1672 Standard
Zvinokosha zvetekinoroji zvinosanganisira:
-
Rated voltage: 300V AC
-
Rated tembiricha: 105 degree
-
Conductor: Yakanamirwa yakasimba kana yakasungwa mhangura isina chinhu (tinned sarudzo iripo)
-
Insulation: PVC (polyvinyl chloride)
-
Bhachi/Kuvharisa: Yakawedzerwa PVC kana XLPVC (muchinjiko-yakabatana PVC)
-
Kunonoka kwemurazvo: Inopfuura UL VW-1 uye CSA FT1 yakatwasuka murazvo bvunzo
Zvichienzaniswa newaya hoka-pamusoro (zvakadai seUL1007), UL1672 ine mbiri-yekuvakwa kwelayer (insulation plus covering). Izvi zvinonyanya kuwedzera abrasion kuramba, simba remagetsi, uye kusimba kwezvakatipoteredza, zvichiita kuti ive yakakodzera kune yemukati wiring application inoda kuchengetedzwa kwakawedzerwa.
Chigadzirwa Chimiro uye Material Properties
Yakajairika UL1672 waya ine zvinotevera zvikamu:
1.Conductor: Yakagadzirwa ne-kuchena annealed copper, ichipa magetsi ekufambisa zvakanaka. Stranded conductors (semuenzaniso, 7/0.193mm ye24AWG) inopa kuchinjika kwepamusoro, ichiita kuti ive yakakodzera kune zvikumbiro zvinosanganisira kugara uchikotama. Tinned shanduro inopa yakawedzera oxidation kuramba uye solderability.
2.Insulation: Uniformly extruded PVC material inovimbisa kuenderana ukobvu, kufambisa nyore kubvisa uye kugadzirisa kugadzirisa. PVC inopa zvinhu zvakanaka zvekudzivirira magetsi uye mutengo-kushanda.
3.Outer Kuvhara: Imwe yakawedzera extruded layer yePVC kana XLPVC inopa mechanical kudzivirira. Chifukidziro ichi chinosiyanisa UL1672 kubva kune imwe-waya dzakadzivirirwa; Ukobvu hwayo hwakamira hunovimbisa kuramba kune abrasion uye kumanikidza.
Outstanding material properties:
1.Environmental resistance: Kurwisana nemvura, mafuta, acids, solvents, uye fungal kukura; yakakodzera nzvimbo dzeindasitiri.
2.Flame retardancy: Utsi hushoma uye hushoma hwehutu; inosangana nezvinodiwa zvekuchengetedza moto.
3.Flexibility uye processability: Uniform ukobvu facilitates otomatiki waya kubvisa uye soldering; inoramba kunyunguduka kana yasangana nesimbi inosunga (kunyanya XLPVC vhezheni).
4.Color coding: Inotsigira mavara akasiyana-siyana mavara (eg, tsvuku, dema, bhuruu, machena) kuti zvive nyore kudhindwa kwedunhu.
Semuyenzaniso, iyo pepa rezvirevo rakapihwa nefekitori yedu rinoratidza kuti 18 AWG stranded conductor vhezheni inoratidzira yakadzikama yekunze dhayamita, ine huremu uye kupikisa kukosha kuzadzisa zviyero, uye yakanyanya kupikisa conductor pa 20 dhigirii inochengetwa mukati mehumwe hunonzwisisika.
Kuongororwa kweKushanda Kwakanakira
1. Chengetedzo uye Kutevedza: UL certification inoratidza kuti chigadzirwa chakaitwa zvakaomesesa murabhoritari kuyedzwa, kusanganisira voltage standstand, kuchembera kwemafuta, kunonoka kwemoto, uye mechanical stress bvunzo. Mumusika wekuNorth America, iyi inoshanda se "pasipoti" yekupinda muzvikamu zvakaita semidziyo yemumba nemidziyo yekurapa. Asi-waya dzakayerwa UL dzinogona kutadza kupihwa zvitupa kana kuisa njodzi yekuchengetedza.
2. Tembiricha uye Voltage Kukodzera: Iyo 105 dhigirii tembiricha rating inodarika iyo yakawanda yakajairwa PVC waya (80 dhigirii), ichibvumira kushanda kwakagadzikana mukupisa kwepamusoro ambient. Iyo 300V voltage rating yakakodzera kune akawanda akadzikira-voltage emukati maseketi.
3. Mechanical Durability: Iyo mbiri-layer yekuvaka inopa zvakanakisa kusagadzika kwebrasion, zvichiita kuti inyatsokodzera kutenderera kumucheto kwakapinza kana mukati memichina inozunguza. Zvichienzaniswa newaya imwe-yakavharidzirwa, zvinoderedza njodzi yekukuvadzwa kwekudzivirira.
4. Hushamwari Hwezvakatipoteredza uye Kuenderana: Vagadziri vakawanda vanopa lead-yemahara, RoHS{2}}shanduro dzinoenderana dzinotsigirawo CSA AWM certification, zvichiita kuti pave nembiri mbiri pamusika wekuNorth America.
5. Mutengo-Kushanda zvakanaka: Nepo tichiuyisa mashandiro akavimbika, PVC-zvakavakirwa pamitengo ine mwero, zvichiita kuti zvive zvakanakira kugadzirwa kwevazhinji.
Mamiriro ekushandisa akakosha
UL1672 inoshandiswa zvakanyanya mu:
-
Wiring yemukati yemidziyo yemumba: Air conditioner, maoveni emicrowave, zvibikirwo zvemupunga, makabhati ekuuraya utachiona, uye zvimwe midziyo yemumba.
-
Midziyo yemagetsi: Kudzora mapaneru, zviridzwa, magetsi adapter, komputa peripherals, uye maindasitiri otomatiki michina.
-
Zvishandiso zvekurapa uye nemazvo: Kubatana kwemukati kwemidziyo yekurapa inoda kuvimbika kwakanyanya uye kunonoka kwemoto.
-
Mamwe maapplication: Marobhoti, zvidzoreso zveelevator, mota dzemagetsi ekubatsira masisitimu (asiri-tambo dzemagetsi), nezvimwe.
Mumashandisirwo anoshanda, UL1672 inowanzoshandiswa sehuku yemukati-waya yematurusi emuchina, makabati ekudzora, nemidziyo. Kuchinjika kwayo uye kupikisa kwemakemikari kunovimbisa kuita kwakanakisa munzvimbo dzekuisa fekitori. Zvinoenderana neUL nhungamiro, iyi mhando yeAWM waya inonyanya kuitirwa fekitori wiring sechinhu chemukati chekubatanidza chemidziyo.
Kuenzanisa nemamwe UL zviyero
Kunzwisisa panopinda UL1672 kunobatsira nesarudzo yakakodzera:
UL1007: Yakatemerwa 80℃uye 300V ine single-layer insulation; yakatetepa uye inowanzoshandiswa kuita hoko yemukati-up wiring. UL1672 ine mbiri-yakapetwa dhizaini inopa dziviriro yepamusoro.
UL1015: Yakarongerwa 80-105 dhigirii uye 600V; inobata magetsi epamusoro, kunyange ukobvu hwayo hunogona kusiyana, zvichiita kuti ikwane kune yakakwirira-magetsi ekushandisa.
UL1061: Inosanganisira semi-yakaomarara PVC insulation; yakakodzera kune chaiyo yekurekodha michina.
UL1571: Inoratidzira yakaonda insulation; inokodzera nzvimbo{{0}maapplication akaganhurirwa.
UL1672inopa mwero wakanakira kukora, kudzivirira, uye mutengo, zvichiita kuti inyatsokodzera-kukodzera maapplication anoda imwe kuchengetedzwa kwemuchina uko magetsi asingapfuuri 300V.
Indasitiri Maitiro uye Ramangwana
Maitiro ezvigadzirwa zvemagetsi ndeye miniaturization, kubatanidzwa kwepamusoro uye smart function, izvo zvinotungamira kune zvakanyanya uye zvakanyanya kuomesesa zvinodiwa patambo dzemagetsi. UL1672 yakaramba ichishanduka seyakajairwa kuti isangane nezvisungo zvezvakatipoteredza senge RoHS kutevedzera, halogen yemahara yakatarwa, uye yakaderera chiutsi maitiro. Muchinjika-zvishandiso zvakabatana uye matekinoroji epamusoro-soro achawedzera kuita zvakanaka muzvizvarwa zvinotevera.
China ndiyo kiyi yekugadzira hwaro hwewaya dzemagetsi mune yepasi rose yekugovera cheni. Mafekitari mazhinji muChina akatumira kunze nhamba huru yezvigadzirwa zvinosangana neUL1672 zviyero, zvinosimudzira kukura kwemidziyo yemumba uye maindasitiri emagetsi.
Mhedziso
UL1672 waya ndiyo inosarudzika sarudzo yevazhinji mainjiniya nekuda kwekuchengetedza kwayo kwakavimbika kuita, yakanakisa mekiniki zvivakwa uye kushanda kwakafara. Iyi haisi iyo yakanyanya "yepamusoro yekupedzisira" waya kunze uko, asi ndeimwe yeanonyanya kushanda uye akaenzana. Kana iwe ukagadzira maseketi emidziyo yemumba, chengetedza zvishandiso zvemaindasitiri, kana sosi yemagetsi zvikamu, kuziva UL1672 kuchakubatsira kuita sarudzo dziri nani.
Innovation ine kuchengeteka sechinhu chepasi. UL certified waya tambo yakasimba yekudzivirira kune zvigadzirwa zvako uye kune avo vanoshandisa zvigadzirwa zvako.
