Itreyi yeCablevs. UkuQokelelwa kweeCable: Umahluko obalulekileyo kwiingcali zokuthenga
Isikhokelo soKhetho lokuHlanganisa umbane kwiMizi-mveliso nakwiZakhiwo
Ekuthengeni iziseko zombane, ukudibanisa iiCable Trays neCable Trunking kunokubangela ukuba iindleko zeprojekthi zigqithise kwaye zingaphumeleli. Njengabenzi bezigqibo, ukuqonda umahluko wabo osisiseko kubaluleke kakhulu ekulawuleni umngcipheko.
I. Ukwahluka kweSakhiwo kulawula ukusetyenziswa
Itreyi yeCable: Izakhiwo ezivulekileyo ezikumgangatho wemizi-mveliso (uhlobo lweleli/uhlobo lwe-mesh) okanye iinkqubo zetreyi ezivaliweyo kancinci, umthamo wokuthwala ungaphezulu kwe-500kg/m. Ixabiso eliphambili lixhomekeke ekuthwaleni umthwalo ophezulu, ukusasaza ubushushu okuphezulu, kunye nokugcinwa okulula.–ilungele iintambo zombane ezikwiziko ledatha, kwizikhululo zombane, nakwizakhiwo zepetrochemical.
Ukugquma ngentambo: Iitshaneli ze-PVC ezivalekileyo okanye zentsimbi encinci ezikumgangatho wesakhiwo, umthamo wazo udla ngokuba yi-<50kg/m2. Yenzelwe ukuthutha izinto ngendlela efihlakeleyo kunye nokhuseleko olusisiseko, ifanele kuphela ukukhanyisa/iisekethe ze-voltage ephantsi kwiiofisi okanye kwiivenkile ezinkulu.
II. Iingxaki Zokuthenga Ezibizayo
Amanqanaba oKhuselo aGqwethiweyo
Iitreyi ezivulekileyo (IP30) ezisetyenziswa kwizityalo zeekhemikhali zikhawulezisa ukubola kweentambo (>30% ukunciphisa ubomi bexesha);
I-Trunking (IP54) ayinakuthatha indawo yokumelana neempembelelo zeetreyi kwiindawo zoomatshini abanzima (ifuna isiqinisekiso se-IEC 61537 Category C).
Ukungalingani koMthwalo
Iprojekthi yezibuko ifumene iindleko zokulungiswa ngokutsha ze-¥800k emva kokuba i-trunk iwile phantsi kweentambo ze-voltage ephezulu. Ukuthengwa kufuneka kuqinisekise:
Iitreyi: Iingxelo zovavanyo lomthwalo womntu wesithathu (ASTM D638/GB/T 2951.11)
Ukugquma: Uvavanyo lomthwalo olutshintshayo (≥ukhuseleko oluphindwe ka-1.5x kwiindawo ezingcangcazelayo)
III. Inkqubo yokuThenga eqhutywa yiDatha
Ipharamitha Umda weTreyi yeCable Umda Wokugquma
Ububanzi beCable ≥20mm ≤10mm
I-Amperage yeSekethe ≥250A ≤63A
Ubushushu obugciniwe -40℃~120℃(ifakwe i-galvanized) -5℃~60℃(I-PVC)
Imfuneko yeNyikima Kunyanzelekile kwiZone 9 Akuvumelekanga kwizakhiwo zenyikima
Isicwangciso sokuSebenza sokuThenga:
Izibhengezo zesimo sesicelo semfuno ezivela kubaboneleli (itreyi ecacileyo/ububanzi bokugquma)
Kufuneka ukulinganisa umthwalo weBIM kwiitreyi (ukuguqulwa < L/200 phantsi koyilo lwentambo yokwenyani)
Iiodolo zokulungisa imithwalo kufuneka zibandakanye isiqinisekiso somlilo (i-GB 8624 B1 iyimfuneko kwizakhiwo zikawonke-wonke)
Isiphelo: Iitreyi zekhebula “ziindlela zentsimbi” zokuhambisa umbane kwimizi-mveliso, ngelixa i-trunking isebenza “njengeendlela zeplastiki” zokufaka iingcingo zokwakha. Ukuthengwa kufuneka kuseke inkqubo yovavanyo lobuchwephesha egxile kumthwalo, okusingqongileyo, kunye nobomi bomsebenzi ukuthintela umngcipheko wekhonkco lokubonelela ngeenkonzo obangelwa kukudideka kwengqondo.
