Cov xov hlau thiab kab hluav taws xob yog insulated nrog yas thiab roj hmab sheaths. Cov ntaub ntawv no yog cov ntaub ntawv pov thawj engineering nrog ntau qhov chaw, uas muaj peev xwm ua tau raws li qhov yuav tsum tau ua ntawm ntau lawm, thiab tus nqi kuj tsawg.Tab sis rau qee qhov kev lag luam tshwj xeeb xws li petrochemical, steel, aerospace, nkoj tsim, kev lag luam ua tsov rog, chaw muag tshuaj, khoom noj, plastics machinery, boilers thiab lwm yam kev lag luam muaj feem xyuam nrog cov cua sov thiab kub, txhua qhov yuav tsum muaj peev xwm tiv taus qee qhov kub thiab xaim xaim , cov hlau tsis zoo nkauj thiab cable tsis tuaj yeem siv, xav kom muaj peev xwm ntawm kev siv cov xov tooj kub thiab cable kom muaj kev ruaj ntseg ntawm lub zog thiab lub teeb liab.
Nrog rau peb lub teb chaws kev lag luam txhim kho sai, qhov tshwj xeeb kev lag luam xav tau kub cable tau loj hlob theem theem, kub tsis kam thiab kub cable yog loj hlob ntawm 20% ib xyoo, kub cable raws li ib feem tseem ceeb ntawm cov xaim tshwj xeeb, muaj muaj zog heev qhov tseem ceeb, nyob rau hauv kev luv luv, Tuam Tshoj tau kwv yees kwv yees li ob txhiab yuan ib xyoos rau kev tsim kho hauv tsev.
Cov kev cai dav dav ntawm International Electrotechnical Commission (IEC) rau cov qib ntawm cov tshav kub tsis kam ntawm kev rwb thaiv tsev yog raws li nram no:
Thaum tshav kub kub ua hauj qib YAEBFHC
Kub siab tso cai ua haujlwm kub / ℃ 90105120130155180≥180
Kev rwb thaiv tsev thiab sheathing rau cov xaim hluav taws xob thiab cov xaim siv hauv peb qhov kev lag luam yog ua los ntawm kev siv cov roj hmab siv hluav taws xob thiab yas raws li cov khoom siv yooj yim, tab sis lawv yuav tsum muaj kev rwb thaiv tsev qib.Cov khoom siv roj hmab siv rau cov xaim hluav taws xob yog: butadiene roj hmab, ethylene propylene roj hmab, ntuj roj hmab thiab chlorosulfonated polyethylene, thiab lwm yam, qhov kub ua haujlwm yog (60 ~ 75) ℃;Cov ntaub ntawv siv cov yas yas siv yog POLYvinyl chloride, polyethylene (suav nrog crosslinked polyethylene) thiab polypropylene, thiab lwm yam, qhov ua haujlwm kub yog (70 ~ 90) ℃.Yog li, cov txuas hluav taws xob no tsis raug nruj tiv thaiv tshav kub lossis hluav taws xob kub.
Thaum tshav kub kub resistant cable feem ntau hais txog (90 ~ 155) ℃ thiab hauv qab lub cable, thiab qhov kub kub cable yog 180 ℃ thiab siab tshaj cov cable.Yuav kom daws tau qhov teeb meem ntawm qhov kub thiab txias tsis kam ntawm cov hluav taws xob uas siv tau zoo heev, nws yog qhov tsim nyog los txhim kho cov khoom siv, los yog siv cov khoom kub tiv thaiv rwb thaiv tsev kawm cov ntaub ntawv.
