The cable conductor of mineral cables amapangidwa kwambirimkuwa conductive, pamene kutchinjiriza wosanjikiza ntchito inorganic mchere kugonjetsedwa ndi kutentha ndi zosayaka. Kudzipatula wosanjikiza amagwiritsa inorganic mchere zinthu, ndi m'chimake akunja amapangidwautsi wochepa, zinthu zapulasitiki zopanda poizoni, kuwonetsa kukana kwa dzimbiri kwabwino kwambiri. Popeza mwamvetsetsa bwino zingwe zamamineral, kodi mungafune kudziwa zofunikira zake? Tiyeni tifufuze mu zimenezo.
01. Kukana Moto:
Zingwe zamamineral, zopangidwa kwathunthu ndi zinthu zakuthupi, sizimayaka kapena kuthandizira kuyaka. Sapanga mpweya wapoizoni ngakhale atakumana ndi malawi akunja, kuwonetsetsa kuti akupitiliza kugwira ntchito pambuyo pamoto popanda kufunikira kosintha. Zingwezi ndizopanda moto, zomwe zimapereka chitsimikizo chotsimikizika cha mabwalo otetezera moto, kupititsa mayeso a IEC331 a International Electrotechnical Commission.
02. Kutha Kwapamwamba Kwambiri Pakalipano:
Zingwe zotetezedwa ndi mchere zimatha kupirira kutentha mpaka 250 ℃ panthawi yogwira ntchito bwino. Malinga ndi IEC60702, kutentha kosalekeza kwa zingwe zotsekera mchere ndi 105 ℃, poganizira zida zosindikizira komanso zofunikira zachitetezo. Ngakhale izi, mphamvu zawo zonyamulira zamakono zimaposa kwambiri zingwe zina chifukwa cha magnesium oxide powder's super conductivity poyerekeza ndi mapulasitiki. Choncho, pa kutentha komweko kogwira ntchito, mphamvu yonyamula panopa ndi yaikulu. Kwa mizere yomwe ili pamwamba pa 16mm, gawo limodzi la mtanda likhoza kuchepetsedwa, ndipo m'madera osaloledwa kukhudzana ndi anthu, magawo awiri odutsa amatha kuchepetsedwa.
03. Kukana Madzi, Kuphulika-Umboni, ndi Kukaniza kwa Corrosion:
Kugwiritsa ntchito utsi wochepa, wopanda halogen, zinthu zosagwira moto kwambiri pakuyikako kumatsimikizira kukana kwa dzimbiri (kuyika pulasitiki kumangofunika pakakhala dzimbiri lamankhwala). Kondakitala, zosungunulira, ndi zoziziritsa kukhosi zimapanga chinthu cholimba komanso chophatikizika, chomwe chimalepheretsa madzi, chinyezi, mafuta, ndi kulowerera kwa mankhwala ena. Zingwezi ndizoyenera kugwiritsidwa ntchito m'malo ophulika, zida zosiyanasiyana zoteteza kuphulika, ndi mawaya a zida.
04. Chitetezo Chowonjezera:
Mu zingwe zapulasitiki, overcurrent kapena overvoltage imatha kuyambitsa kutentha kwa insulation kapena kuwonongeka panthawi yodzaza. Komabe, mu zingwe za mineral insulated, malinga ngati kutentha sikufika posungunuka mkuwa, chingwecho chimakhalabe chosawonongeka. Ngakhale pakuwonongeka kwakanthawi, kutentha kwa magnesium oxide pamalo osokonekera sikupanga ma carbides. Pambuyo pochotsa katundu wambiri, ntchito ya chingwe imakhalabe yosasinthika ndipo ikhoza kupitiriza kugwira ntchito bwino.
05. Kutentha Kwambiri:
Malo osungunuka a magnesium oxide insulation ndi apamwamba kwambiri kuposa amkuwa, zomwe zimalola kutentha kwanthawi zonse kwa chingwe kufika pa 250 ℃. Itha kugwira ntchito pa kutentha pafupi ndi malo osungunuka amkuwa (1083 ℃) kwakanthawi kochepa.
06. Kuchita Kwamphamvu Kwachitetezo:
Chophimba chamkuwawa chingwe umakhala ngati chitetezo chotchinga bwino kwambiri, kuteteza chingwecho chokha kuti chisasokoneze zingwe zina ndi maginito akunja kuti asakhudze chingwe.
Kuphatikiza pazikuluzikulu zomwe tazitchulazi, zingwe zama mineral zilinso ndi zinthu monga kutalika kwa moyo, m'mimba mwake yaying'ono, yopepuka, kukana kutentha kwa ma radiation, chitetezo, kusamala zachilengedwe, kukana kuwonongeka kwamakina, kuchita bwino kupindika, komanso kukhazikika bwino.
