Kev faib hluav taws kub-Resistant Cables

Hauv Suav teb, cov hluav taws kub txheem txheem- cov kab hluav taws xob tiv thaiv tau muab faib ua Class A thiab Class B. Class B cables tuaj yeem tiv taus hluav taws kub ntawm 750℃-800℃thaum nyob rau hauv qhov ntsuas hluav taws xob tsawg kawg 90 feeb yam tsis muaj hluav taws xob tawg (piv txwv li, tsis tau tshuab 3A fuse). Class A hluav taws- cov kab hluav taws xob tiv thaiv tau tsim los ntawm kev txhim kho cov txheej txheem tsim khoom thiab txhim kho cov hluav taws kub- txheej tiv thaiv; Cov kab hluav taws xob no tuaj yeem tiv taus nplaim taws ntawm 950℃-1,000℃nyob rau hauv qhov ntsuas hluav taws xob tsawg kawg 90 feeb yam tsis muaj hluav taws xob tawg (piv txwv li, tsis tau tshuab 3A fuse). Class A cables muaj kev tiv thaiv hluav taws zoo dua piv rau Class B cables. Tsis tas li ntawd, mineral-insulated (MI) cables sawv cev rau qib siab -kev ua tau zoo ntawm cov hluav taws kub- tiv taus cable; lawv yog tsim los ntawm tooj liab cores, tooj liab sheaths, thiab magnesium oxide rwb thaiv tsev. Tsis zoo li cov hluav taws kub txheem-cov kab hluav taws xob tiv taus- uas siv cov hluav taws sib xyaw ua ke-cov ntaub ntawv tsis muaj zog thiab cov organic- MI cables muaj qhov hluav taws kub- cov txheej tiv thaiv uas muaj cov khoom siv tsis zoo. Yog li ntawd, MI cables muaj kev tiv thaiv hluav taws zoo tshaj plaws thiab tsis tawg kom tso cov roj corrosive thaum lub sij hawm combustion. MI cables muaj hluav taws kub zoo heev-cov khoom tiv taus thiab tuaj yeem ua haujlwm tsis tu ncua ntawm qhov kub thiab txias ntawm 250 degree. Lawv kuj muaj qhov zoo xws li tawg- muaj peev xwm ua pov thawj, muaj zog corrosion kuj, siab tam sim no - nqa lub peev xwm, hluav taws xob tsis kam, siab txhua yam muaj zog, compact loj, lub teeb yuag, lub neej ua haujlwm ntev, thiab kev ua haujlwm tsis muaj pa taws. Txawm li cas los xij, vim lawv cov nqi siab, kev tsim khoom, thiab teeb meem kev teeb tsa, lawv feem ntau ua haujlwm nyob rau hauv qhov chaw uas muaj hluav taws kub hnyiab yog qhov tseem ceeb thiab tus nqi tsim nyog-xws li cov chaw cia roj, cov tsev tseem ceeb rau pej xeem nrog cov ntoo ntoo, thiab siab - ib puag ncig kub.
