Tambo-yakakosha tambo inobatsira kubatanidza zvishandiso nemichina kune mains.
Saizi ye3-core tambo dzaunosarudza kushandisa uye magadzirirwo aunoita dunhu rako anogona zvakare kukanganisa chirongwa chako.
Nekuda kwekusiyana kwemashandisirwo uye kusiyanisa mukutsanangurwa kweprojekiti.
Kuwedzera, high-voltage applications kazhinji inoda tambo dzemhando yepamusoro, inozivikanwa sesimbi wire armor (Swa), uye maitiro avo anoshanda uye zvakatemwa.
Saka, iwe unofanirwa kujairana ne-3-core armored cable mavara, uye kuti makondukita eruvara rumwe norumwe ndeei.
Mutsamba iyi, tichakurukura nyaya dzose idzi zvakadzama.
Chii chinonzi Three-core Cable?
Zvakakosha kuziva rudzi rwewaya kana tambo yauchashandisa.
Hazvina mhosva kuti ndeipi application yemagetsi yaunoronga kushanda mairi.
Sarudzo yakakurumbira yezvinangwa zvakasiyana ndeye 3-core tambo.
Tambo idzi dzine matatu akapatsanurwa macores matatu akasiyana ekufambisa magetsi.
Semuyenzaniso, kana ukasarudza kushandisa 1.5mm 3-core flex cable, pachava netambo nhatu dzakaparadzana mukati mebhachi guru retambo.
Imwe yewaya ndeyekuisa magetsi, imwe yacho ndeyewaya dzisina kwazvakarerekera, uye waya yechitatu mune 3-core tambo ndeyepasi (kana pasi) Zvishandiso.
Zvinogona kubatsira kuongorora ruzivo rwuri pamusoro kubva pakuona kwemamwe marudzi ewaya.
Kusiyana ne3-core cables, 2-core cables ane one less conductor. Gungano rayo rinongori macores maviri chete.
Saka, nepo 10mm 3-core armored tambo ine mhenyu, kwaakarerekera, uye pasi (kana pasi) waya, iyo inoenderana 2-core vhezheni yetambo imwechete haina pasi conductor. Inongova nemaconductors ehupenyu uye asina kwaakarerekera.
Chii chinonzi Three-core Ground Wire Inoshandiswa?
Iwo anowanzo shandiswa mukushandisa senge 2-nzira yekuvhenekesa yekushandiswa kwekugara, uyewo mune mamwe maapplication. Zvakadai sepakati kudziyisa masisitimu uye wiring yemidziyo.
Zvichienderana nekuti mugadziri wemagetsi anogadzira sei dunhu reiyo 2-nzira yekuvhenekesa.
Iwo 3-core uye pasi tambo dzinogona kunge dzisina kwazvakarerekera kana mhenyu maapplication.
Kazhinji, tambo ine-matatu-core (three-core cable) inoreva waya ine mhangura nhatu dzakaparadzana, imwe neimwe mukati mejasi rayo rekudzivirira.
Zvisinei, kune 3-core pasi waya, kondakita wechina anoiswa panguva yekugadzira.
Semuyenzaniso, yakajairika 3-core flex tambo ichave neyakajairika 3-cores, kusanganisira live, kwaakarerekera, uye pasi, asi achavawo nomumwe muitisi—wechina.
Iyi yakawedzera musimboti kazhinji inoshama mhangura yezvinangwa zvekugadzika pasi.
Mumuenzaniso uri pamusoro apa , dai taishandisa 3-core flex cable ine an extra bare copper conductor, kondakita wechina aifanira kuiswa mugirini/yellow coded sleeve (pasi) Munguva yekuisirwa.
Matatu-epakati Armored Cable yeMagetsi Zvishandiso
Core armored tambo inowanzo zivikanwa sematatu-musimboti simbi waya armored (Swa) Cable.
Semuyenzaniso, iwe unogona kuona chirevo chinoti armored cable 16mm 3 cores, BS546/BS6724.
Izvi zvinoreva kuti tambo inosangana nezvinodiwa zveiyo chaiyo UK tambo yekugadzira uye yekuyedza zviyero.
Tambo nhatu dzepakati dzakashongedzwa dzinozivikanwa se simba uye tambo dzekubatsira kudzora.
Iyo inozivikanwawo se 3-core power cables, tambo idzi tambo dzisingapfeki uye dzinoshandiswa mukushandisa uko tambo inogona kukuvadzwa kana paine njodzi yekubuda pachena kweUV..
Iyo yakajairika 3-core simbi waya armored tambo (Swa) yakanakira kushandiswa kwemagetsi ekunze.
Sezvo kushandiswa kwakadaro kunowanzofanira kutsungirira masimba echisikigo, SWA Kunze 3-core tambo dzine yekuwedzera yekunze sheath (kazhinji waya mesh)
Inopa kuchengetedzwa kwakakura kwemichina kune yemukati musimboti weakadaro 3-core cables.
Chii Is ivo Three-core Ckugona Used for?
Sezvambotaurwa, matatu-conductor tambo itambo ine matatu conductor panguva yekugadzira tambo.
Mhando imwe neimwe yetambo inoshandisa chinangwa chakasiyana, uye isu hatikurudzire kune chakananga-chinangwa maapplication.
Semuyenzaniso, kana yako yakanakira iri 1mm 3-core tambo, inogona kunge isiri iyo yakanakisa tsika yekuchinja uye kushandisa gobvu kana nhete tambo.
Kazhinji, 3-core cable inowanzo tambo yesarudzo yeKirasi I yekubatanidza kune zvishandiso.
Izvi zvinodaro nekuti michina yakadaro (kana maapplication anoenderana) inoda kupa chinongedzo kuNyika.
Two-core Cables vs Three-core Cables
Kushandisa 2-core waya panzvimbo ye3-core tambo mune izvi maapplication kunogona kukanganisa kuisirwa. Kutadza kuvhurika kungafumura mushandisi kuvhunduka kwemagetsi.
Vagadziri vemagetsi vanogona kushandisa iyo 2-musimboti vhezheni yetambo pachinzvimbo cheiyo 3-core tambo mune zviitiko apo pasi kusiri kudiwa..
Semuyenzaniso, muchikumbiro chinosanganisira chinhu cheClass II, injiniya kana nyanzvi yemagetsi inogona kushandisa 2-conductor yakarukwa tambo panzvimbo ye3-core yakarukwa tambo..
Chikonzero chekushandiswa uku ndechekuti Kirasi II michina kazhinji haidi yekubatanidza pasi.
To sum up, tambo dzinowanzoenderana nekuti mudziyo kana mudziyo unoda kudzikwa.
Maererano nekodhi yemagetsi, kuvharirwa kwe a Class I mudziyo inofanira kumiswa.
Nokuda kweizvi, shandisa tambo yemagetsi 3-core. Pane rimwe divi, kushandisa 2-conductor tambo yakachengeteka kune Kirasi II maapplication.
Mukushandisa uko kune njodzi huru yekuvhunduka kwemagetsi kana waya mhenyu yabata muviri wemidziyo kana mudziyo., 3-core grounded cable inokurudzirwa.
Semuyenzaniso, kana muviri wakagadzirwa nechinhu chisina-conductive, zvakadai serabha, plastiki, girazi, kana ceramic, zvingasave zvakakosha kushandisa 3-core cable.
Zvisinei, zvingave zvakachengeteka kusarudza yekunze 3-core tambo pamusoro pekunze conductive 2-conductor waya sesimbi., simbi, iron, kana mhangura.
Unogona kushandisa 2-conductor tambo yezvisiri-conductive application, asi iwe unofanirwa kushandisa 3-musimboti tambo ye bulb sockets, zvigadziko zvemwenje, uye chero mamwe maitiro ekushandisa uko kune njodzi yakakura yekuvhunduka kwemagetsi.
Kazhinji, 3-core simbi waya armored cables (Swa) anoshandiswa kufambisa simba pasi pevhu, kubva kumagetsi ekugadzira magetsi kuenda kunzvimbo yekugara kana yekutengesa.
Iwe unogona zvakare kuona zvimwe zvigadzirwa zvehondo, senge 3-musimboti 4mm tambo dzezvombo, inoshandiswa nekatenari waya mune pamusoro pepamusoro magetsi ekufambisa maapplication.
Kazhinji, kushandiswa kwemagetsi zvakajairika, sematambo emagetsi ekuvheneka ma switch kana midziyo yemagetsi, inogona kushandisa waya dzinochinjika senge 3-core flex cables.
Izvi zvinodaro nekuti kushandiswa kwadzo kunoita kuti tambo dzikwanise kukotama nekumonyoroka pasina njodzi yekutyoka kana kupatsanuka.
Iwo Mavara e3-core Cables
Ose ari maviri-conductor uye 3-core tambo ane chaiwo mavara anodiwa.
Muna March 2004, British Standard BS 7671 kubata nekuisa magetsi akaita shanduko kune 2- uye 3-core mavara muUK.
Shanduko dzezviyero izvi dzakatanga kushanda muna Kubvumbi 1, 2004.
Semuyenzaniso, pamberi paApril 1st, waiona vagadziri vetambo vachitengesa 25mm 3-core armored cables mune akasiyana mavara, asi mushure mekunge chiyero chitsva chatanga kushanda, hazvisi pamutemo (kubva muna Kubvumbi 1, 2006) kutengesa kana Kushandisa tambo dzine zvirongwa zvekare zvemavara.
Kusvikira March 2004, chiyero chemavara che3-core ground wire yaive yebhuruu, yero, tsvuku, newaya yepasi.
Zvisinei, mushure meMarch 2004, iwo matsva 3-core cable mavara ane grey, dema nebrown pamwe chete nemavara epasi.
Aya mavara emavara haashande nehusiku humwe – pane 2-year kupindirana (nguva yenyasha) isati yashanduka.
Munguva iyi, vatengesi vakatengeswa 2- uye 3-core armored cables, pamwe nemamwe marudzi matatu-conductor zvigadzirwa, zvose zvekare uye zvitsva zvigadziriso zvemavara.
Sei Uyu Muitiro Wemavara Wachinja?
Inoshandurwa kunyanya kuchengetedza mavara etambo anoenderana nedzimwe nyika dzeEU.
Mauniform mavara macode ave kushanda munyika dzese dzeEurope pamwe neUK.
Pasi pehurongwa hutsva, kana application yako ichida chigadzirwa chakadai se3-core flat cable, ichatengesa chete mavara emavara ekondinendi yese muhurongwa hutsva.
