Iintambo ze-multi-conductor ezinenjongo ngokubanzi, ngakolunye uhlangothi, zineendlela ezibanzi zokusetyenziswa, ezixhasa yonke into ukusuka kwiinkqubo zokukhusela ukuya kwi-automation kunye nokulawula ukukhanya.

2.Umahluko phakathi kweeConductor kunye nezibini

Xa kuthengwa iintambo ezininzi ze-conductor, abathengi banokuqaphela iindidi ezimbini ezahlukeneyo: inani labaqhubi kunye nenani lezibini. Ii-conductor zibhekisela kwiingcingo zomntu ngamnye kwintambo, ngelixa izibini zibhekisela kwiingcingo eziphothiweyo kunye.

3. Usetyenziso oluSithandathu oluqhelekileyo lweCable ye-Multi-Conductor

Makhe siphonononge iindidi ezintandathu eziphambili zeemveliso zentambo ze-multi-conductor: intambo yokulawula i-voltage ephantsi, intambo ye-alam, intambo yesiriyali, intambo ye-thermostat, intambo yokukhanyisa i-LED, kunye nentambo yeribhoni eflethi.

1. Intambo yokulawula i-low-voltage:Iintambo zokulawula i-low-voltage zisetyenziselwa izicelo apho iimpawu zombane eziphantsi zifunekayo ukulawula oomatshini, ukuzenzekelayo, okanye iinkqubo zokwakha. Ezi ntambo ziqhele ukusetyenziswa kwiindawo zemizi-mveliso, iirobhothi, kunye nolawulo lweHVAC. Baqinisekisa ukuhanjiswa kwesignali ethembekileyo ngaphandle kwemfuneko yeentambo zombane eziphezulu, ezibenza zibe yinxalenye ebalulekileyo ye-automation yanamhlanje.

2. Intambo yealam:Intambo ye-alam luhlobo olukhethekileyo lwentambo ye-multi-core eyenzelwe iinkqubo zokhuseleko, ii-alamu zomlilo, kunye nezicelo zokulawula ukufikelela. Ezi ntambo ziqinisekisa ukuhanjiswa okungenamthungo kwe-alarm triggering kunye nezaziso, ukukhusela izakhiwo kunye namakhaya. Ngokuxhomekeke kwindawo yokufakela, iintambo ezinqanda amadangatye zingafuneka ukuba zihambelane nemimiselo yokhuseleko lomlilo kwiintambo zokuqhuba kwiindawo zokuphatha umoya.

3. Intambo yothotho:Iintambo zothotho zisetyenziselwa ukuhambisa idatha phakathi kwezixhobo kwimizi-mveliso, urhwebo, kunye neendawo zothungelwano. Ngokuqhelekileyo zisetyenziswa kwizicelo zentambo zonxibelelwano lwedatha ezifana ne-RS-232, RS-485, kunye nezinye ii-serial interfaces. Iinketho zokukhusela, ezinje ngeentambo ezikhuselweyo, zinceda ukuthintela ukuphazamiseka kwe-electromagnetic (EMI) kunye nokuqinisekisa ukuhanjiswa kwedatha okuthembekileyo.

4. Iintambo zeThermostat:Iintambo zeThermostat zibalulekile kwizicelo zeHVAC. Ezi ntambo zidibanisa i-thermostats kwiinkqubo zokufudumeza kunye nokupholisa, okwenza kube lula ukulawula imozulu. Iintambo zeHVAC zikwadla ngokuba ziintambo ezininzi zokuxhasa imiqondiso eyahlukeneyo yolawulo efunekayo kulungiselelo lokufudumeza okuntsokothileyo kunye nokupholisa.

5. Iintambo zokukhanyisa ze-LED:Iintambo zokulawula izibane zenzelwe ukusetyenziswa kwe-wiring ye-low-voltage kwiinkqubo zokukhanyisa i-LED. Baqinisekisa unikezelo lwamandla olusebenzayo kunye nolawulo lwemigca yokukhanya ye-LED, ukukhanya kwezakhiwo, kunye nezibane zokukhanyisa ekhaya. Ezi ntambo ze-multi-conductor ziyafumaneka ngeendlela zokukhusela. Kwiindawo ezinezixhobo zombane ezininzi, ukhuselo lunokufuneka ukunciphisa ukuphazamiseka kombane.

6. Iintambo zeribhoni ezisicaba:Ngokungafaniyo neentambo ezingqukuva, iintambo zeribhoni ezisicaba zinee-conductor ezininzi ezibekwe ngokungqameneyo, zizenza zilungele ukusetyenziswa kwe-elektroniki. Ngokuqhelekileyo zisetyenziselwa iingcingo zangaphakathi kwiinkqubo zekhompyutha, izixhobo ezizenzekelayo, kunye nezixhobo ezifana nabashicileli kunye neebhodi zesekethe. Ukuguquguquka kwabo kunye noyilo olugcina indawo lubenza babe yintsika kwiinkqubo ezahlukeneyo zekhebula.
