Ithreyi Yekhebulavs. Ukuqoqwa Kwekhebula: Umehluko Obalulekile Kwabachwepheshe Bokuthenga
Umhlahlandlela Wokukhetha Ukuhlanganiswa Kogesi Kwezimboni Nezakhiwo
Ekuthengweni kwengqalasizinda kagesi, ukuhlanganisa ama-Cable Tray ne-Cable Trunking kungabangela ukweqiwa kwezindleko zephrojekthi kanye nokwehluleka kokufakwa. Njengabenzi bezinqumo, ukuqonda umehluko wabo oyisisekelo kubaluleke kakhulu ekulawuleni ubungozi.
I. Ukwehlukana Kwesakhiwo Kubeka Icala Ukusetshenziswa
Ithreyi Yekhebula: Izakhiwo ezivulekile zezinga lezimboni (uhlobo lwezitebhisi/i-mesh) noma izinhlelo zethreyi ezivalekile kancane, umthamo wokuthwala >500kg/m. Inani eliyinhloko lisekuthwaleni umthwalo ophezulu, ukushabalalisa ukushisa okuphezulu, kanye nokugcinwa okulula–ilungele izintambo zikagesi ezikhungweni zedatha, ezitshalweni zikagesi, kanye nasezikhungweni ze-petrochemical.
Ukubopha Ikhebula: Iziteshi ze-PVC noma zensimbi encane ezivalekile ezisezingeni lesakhiwo, umthamo wazo ngokuvamile ungaphansi kuka-50kg/m. Zenzelwe umzila ofihliwe kanye nokuvikelwa okuyisisekelo, zifanelekela kuphela ukukhanyisa/amasekethe anamandla aphansi emahhovisi noma ezitolo ezinkulu.
II. Izingibe Zokuthenga Ezibizayo
Amazinga Okuvikela Angacatshangwa Kahle
Amathreyi avulekile (IP30) asetshenziswa ezitshalweni zamakhemikhali asheshisa ukugqwala kwekhebula (ukunciphisa isikhathi sokuphila okungaphezu kuka-30%);
I-Trunking (IP54) ayikwazi ukuthatha indawo yokumelana nokushayisana kwamathileyi ezindaweni zemishini esindayo (kudinga isitifiketi se-IEC 61537 Category C).
Ukungalingani Kwekhono Lokulayisha
Iphrojekthi yechweba ithole izindleko zokuvuselela ezingama-¥800k ngemuva kokuwa kwe-trunk ngaphansi kwezintambo ezinamandla aphezulu. Ukuthengwa kumele kuqinisekise:
Amathreyi: Imibiko yokuhlolwa komthwalo wenkampani yangaphandle (ASTM D638/GB/T 2951.11)
Ukugoba: Isilinganiso somthwalo oguqukayo (≥Isici sokuphepha esingu-1.5x ezindaweni ezidlidlizayo)
III. Uhlaka Lokuthengwa Oluqhutshwa Yidatha
Ipharamitha Umkhawulo Wethreyi Yekhebula Umkhawulo Wokugoba
Ububanzi bekhebula ≥20mm ≤10mm
I-Amperage Yesekethe ≥250A ≤63A
Izinga Lokushisa Elizungezile -40℃~120℃(ifakwe nge-galvanized) -5℃~60℃(I-PVC)
Isidingo Sokuzamazama Komhlaba Kuphoqelekile ku-Zone 9 Akuvunyelwe ezakhiweni zokuzamazama komhlaba
Uhlelo Lokusebenza Lokuthenga:
Izimemezelo zesimo sesicelo sesidingo ezivela kubaphakeli (ithreyi ecacile/ububanzi bokugoba)
Kudinga ukulingiswa komthwalo we-BIM kumathreyi (ukuguqulwa < L/200 ngaphansi kokuhlelwa kwekhebula langempela)
Ama-oda okulungisa imigwaqo kumele afake isitifiketi somlilo (i-GB 8624 B1 iyimpoqo ezakhiweni zomphakathi)
Isiphetho: Amathreyi ekhebula “ayimigwaqo emikhulu yensimbi” yokudlulisa amandla ezimboni, kuyilapho i-trunking isebenza “njengezindlela zokuhamba ngezinyawo zepulasitiki” zokwakha izintambo. Ukuthengwa kwempahla kumele kusungule uhlelo lokuhlola lobuchwepheshe olugxile emthwalweni, emvelweni, kanye nesikhathi sokuphila ukuze kuvinjelwe izingozi zochungechunge lokuhlinzekwa kwempahla ezibangelwa ukudideka komqondo.
