Overhead service drop cables ndiwo tambo dzinopa kunze tambo dzemagetsi dziri pamusoro. Iyo inzira nyowani yekufambisa magetsi pakati pemakondakita epamusoro uye tambo dzepasi pevhu, iyo yakatanga kutsvagisa nekusimudzira mukutanga kwema1960.
Pamusoro pebasa rekudonhedza tambo dzakagadzirwa neiyo insulation layer uye yekudzivirira layer, yakafanana neyekugadzirwa kwetambo dzakachinjika. Kunyangwe iwo achinyanya kukanganiswa nekukanganiswa kwekunze uye asingafadze, anoshandiswa zvakanyanya munzvimbo dzinonetsa kuisa tambo dzepasi pevhu nekuda kwekuvimbika kwesimba rekupa, kugadzikana, uye kugadzirisa kuri nyore.
Isu tinosarudza sei pamusoro pebasa rekudonha tambo?
Idzo mhando nhatu dzealuminium sevhisi inodonhedza tambo ndeye duplex sevhisi yekudonhedza tambo, triplex service yekudonhedza tambo, uye quadruplex service drop cable. Izvo zvinosiyana zvichienderana nehuwandu hwemakondakita uye zvakajairika application. Ngationei muchidimbu basa rechimwe nechimwe cheizvi.
Duplex sevhisi inodonhedza tambo ine maconductor maviri anoshandiswa mune imwe-chikamu tambo dzemagetsi kune 120-volt application. Inowanzoshandiswa mumagadzirirwo emagetsi kunze, kusanganisira chiedza chemumugwagwa. Uyezve, ivo vanowanzo shandiswa mubhizinesi rekuvaka kuitira basa renguva pfupi. Kunakidza chokwadi- American duplex overhead cable sizes dzinotumidzwa zita remhando dzembwa, kusanganisira setter, shepherd, uye chow.
Triplex sevhisi inodonhedza tambo ine matatu maconductor anoshandiswa kutakura simba kubva kumitsara yekushandisa kuenda kune vatengi, kunyanya, kumusoro wemamiriro ekunze. Zvekare, maAmerican triplex service drop cables ane nyaya inonakidza kuzita ravo. Dzinopihwa mazita emhando dzemhuka dzemugungwa dzakadai sehozhwa, makakanje, uye makakanje. Mazita etambo anosanganisira Paludina, Valuta, uye Minex.
Quadruplex sevhisi inodonhedza tambo dzine maconductor mana akagadzirirwa kupa matatu-chikamu tambo dzemagetsi. Vanobatanidza pole-mounted emagetsi emagetsi, anonyanya kuwanikwa kumaruwa, ane misoro yebasa rekupedzisira-mushandisi. Quadruplex tambo dzinopfuura zvinodiwa neNEC dzinotumidzwa zita remhando dzemabhiza, seGelding neAppaloosa.
Kuvakwa kweAluminium Service Drop Cables
Pasinei nechinangwa chakasiyana uye nhamba yemakondakita, waya dzese dzepamusoro dzemagetsi dzakavakwa zvakafanana. Makondukita etambo idzi akagadzirwa nealuminium alloy 1350-H19,6201-T81 kana ACSR.
Ivo vane muchinjiko-yakabatana polyethylene XLPE insulation inopa dziviriro huru kubva kune njodzi dzekunze. kunyanya, ine yakanyanya kupikisa kunyorova, mamiriro ekunze, uye kukanganisa kwemakemikari akasiyana. Tembiricha yekushanda yealuminium pamusoro petambo neXLPE insulation ndeye 90 degrees Celsius. Kashoma, polyethylene insulation inogona kuiswa panzvimbo yeXLPE insulation. Muchiitiko ichi, tembiricha yekushanda inoderedzwa kusvika 75degrees, chinova chimwe chinhu chinofanira kufunga kana uchifunga nezve purojekiti yako yemagetsi. Chiyero chemagetsi chewaya dzese dzepamusoro dzebasa remagetsi i600 volts.
Ese aluminium service drop cables ane neutral conductor kana messenger wire. Chinangwa chemutumwa conductor kugadzira nzira isina kwayakarerekera yekuti magetsi atize uye kudzivirira tsaona, izvo zvakakosha munzvimbo yekunze kwecabling. Waya dze Messenger dzinogona kugadzirwa nezvinhu zvakasiyana, seAAC, ACSR, kana imwe mhando yealuminium alloy.
Kana uchida kugamuchira kubvunzana nezve service drop conductors, ndapota taura nesu.
