Nzira Yokusarudza Pakati PemaEEMT, PVC uye Mamwe Mafambisi Emagetsi
Yakagadzirirwa Rigid Conduit kana RMC
Dhoni yakagadzirwa kubva pamagetsi akaumbwa nesimbi inowanzozivikanwa sechinhu chakaoma.
Uwandu hwegatidzi yakagadziriswa hunochengetedza wiring motokari kubva pakurohwa uye unobvumira kuti iiswe. Majini akaomeswa akabatanidzwa anoshandiswa nemagetsi magetsi mune zvekutengeserana uye zvemabhizimisi zvinowanzowanika mumamita gumi uye mamita makumi maviri kureba. Iyi ndiyo nzira yemagetsi inoshandiswa pamusoro pegorosi uye ine tsvimbo pazvikamu zvose zviri zviviri nekubatanidza pane imwe mugumo.
Kuiswa kweRigid Steel Conduit (RSC) kunofukidzwa neChitsauko 344 cheNational Electrical Code® (NEC®). Nzira yakasimba yakagadzirwa nemagetsi inogona kurapwa kuti igadzire kupisa kuburikidza nekushandisa zvakasiyana-siyana kumudonzvo. Iyo ndiyo yakanyanya-inorema uye yakareba kudurusa mudambo inowanika mukutengesa kwemaoko ½ kusvika ku6.
Ndeipi Yekushandisa Magetsi Anonzi Metal Tubing (EMT)?
Chimwe chiitiko chegomba rakaoma remagetsi ndeye EMT, inozivikanwawo seMagetsi Metallic Tubing. Mutevedzeri weEEMT wakagadzirwa nesimbi; mune zvimwe zviitiko, aluminium inoshandiswawo, inodhura kudarika gavanized rigid duct uye chiedza kupfuura gorosi GR.
EMT ichinyanya kukoshesa muzvivako zvekutengeserana uye zvemabhizimisi nekuti inogona kunge yakanamatira kune imwe nzvimbo uye mazano uye inopenya kupfuura RMC. Mumakore achangobva kupfuura, emt mitsara yakave yakakurumbira mukugadzirirwa kwekugara sezvo inopa kunze kwekudzivirira kugadzirisa pamusoro.
EMT inoratidzirwa rutsigiro rwemhizha yeyimbi yechitenderera chikamu chikamu , chisina kudzidziswa, uye chinowanzofamba mamita gumi.
Zvimwe Zvemagetsi Zvisiri Mutsara
Ikoseti yemitambo isingaenzanisisi ndeyeimwe muenzaniso wemagetsi emagetsi akagadzirwa nesimbi yakaoma-yakagadziriswa yakavharidza tubing, unhu husingachinji uye rinopisa moto. Iko isiri meshonga yemagetsi inogona kugadziriswa noruoko uye inogona kushandiswa nyore nyore nekuda kwemamiriro ayo akachinja. Zvisinei, kukodzera kushandiswa kushamwaridzana kwete-metallic tubing yakasimba uye haigoni kumira. Kana uri kutsvaga kuiswa nokukurumidza uye kudhura mari yebasa, ichi ndicho chinofanira kufunga.
Flexible Metallic Conduit kana Mushonga-Wakasimba Flexible Metal Electrical Conduit (LFMC)
Shanduro yakagadzirwa nesimbi inogadzirwa nehuni inoputika umo magetsi emagetsi anopfuura. Inokurudzirwa zvikuru munzvimbo dzakaoma. Iyo Flexible Metallic Conduit inonziwo greenfield ye flex flex, haina kuchengeta bend rinogara uye inogona kushandiswa uko EMT isingashandisi kushandisa.
Zvisinei, mvura yakasimba-yakanyatsogadziriswa yakagadzirwa nemashini yakafukidzwa nemapurasitiki epurasitiki. Inhivi mukati maro yakafanana zvikuru neyendaneti yakawanda. Inokurudzirwa kushandiswa munzvimbo dzakawanda wiring, mvura yakasviba kana nzvimbo dzine mvura. Inogonawo kushandiswa kutungamirira kuvigwa; konkiti yakabatanidzwa, uye nzvimbo yekugadzirisa mabasa.
Mvura-yakasimba Flexible Nonmetallic Conduit
Mvura-yakasimba Flexible Nonmetallic Conduit (LNFC) imwe izwi kune mamwe mavara anopisa asingatsvaki midzi. Iyi ndiyo nzira yemagetsi inokurudzirwa semujaho wekugadzwa kwevatungamiri vanobvumirwa vane mazita okuti ma Volt 600 kana zvishoma kune nzvimbo dzisina ngozi. Inyanzvi dzemugwagwa uyu wegetsi dzinogona kuvhiringidzwa kana kushandiswa.
Aluminium Electrical Conduits
An aluminium inogadzirwa isimbi inogadziriswa inowanzoshandiswa mumabasa ekutengeserana uye emabhizimisi. Izvi zvinoshandiswa kugadzirisa kurara uye ndiyo inodedzerwa dheni inoshandiswa munzvimbo dzinowanikwa mvura yakawanda uye nzvimbo dzakagadzikana. Aluminium haigoni kuiswa zvakananga mukrete sezvo simbi inopindirana nea alkalis mu cement asi inogona kudzivirirwa nehumwe hupfeko kuitira kudzivirira konrete kubva pakukanganisa dhara.
Inowanzoshandiswa mukhonkiti slabs kana masvingo.
Iyo Inonyanya Kufanana Neyese Makombiyuta Emagetsi
PVC ndiyo inonyanya kudhonza dutu uye inowanzo inonyanya kutengeswa yemhando. PVC mapipu inogona kusiyanisa muhutano zvichienderana nekushandiswa uye apo PVC ichaiswa. Iyo PVC inotungamirira inopesana nemuviri uye kupisa asi tubing haisi inoitisa mumwe mudzidzisi wevhu anotora inofanira kuendeswa mumudonzvo mumwe nomumwe. PVC inodhonza ine yepamusoro yakawanda yehutemu yekuwedzera inobvumira dhikira kuti riwedzere uye vvumirano. Ngwarira kuisa PVC pasi pevhu mune zvakawanda kana zvakasiyana-siyana zvigadziriro, kutengesa pamwe kunogona kukonzera zvinetso pakushanda kwekambo.
