Ubwino Wotani wa Ma Cable Oteteza Kutentha Kwambiri Osamva Kutentha Kwambiri?

Tanthauzo ndi Mapangidwe Ofunika Kwambiri a Zingwe Zoteteza Kutentha Kwambiri Zotsutsana ndi Kutentha

Zingwe zotetezedwa ndi kutentha kwapamwamba zolimbana ndi dzimbiri ndi zingwe zopangidwa mwapadera zomwe zimagwiritsidwa ntchito potumiza ma siginecha ndi kugawa mphamvu m'malo otentha kwambiri komanso owononga. Kutanthauzira kwawo komanso kapangidwe kawo koyambira ndi motere:

1.Tanthauzo:

Zingwe zotetezedwa ndi kutentha kwapamwamba zolimbana ndi dzimbiri ndi zingwe zomwe zimatha kugwira ntchito mokhazikika m'malo otentha kwambiri komanso owononga, okhala ndi zinthu monga kukana kutentha kwambiri, kukana kwa dzimbiri, kuchedwa kwa lawi, komanso kusokoneza. Amagwiritsidwa ntchito kwambiri m'mafakitale monga mphamvu, zitsulo, ndi petrochemicals, makamaka m'malo ovuta kwambiri ndi kutentha kwambiri, mpweya wowononga, kapena zakumwa.

2. Zoyambira:

Kondakitala: Amapangidwa ndi zinthu zosagwira dzimbiri monga mkuwa wopanda mpweya wa okosijeni kapena mkuwa wothira kuti zitsimikizire kutentha kwambiri komanso kuwononga.
Insulation Layer: Imagwiritsa ntchito zinthu zosagwirizana ndi kutentha kwambiri, zolimbana ndi ukalamba mongapolyethylene yolumikizidwa (XLPE)kuonetsetsa kuti chizindikiro kapena kufalikira kwatsopano ndi chitetezo.
Shielding Layer: Imalemba ntchito zomata zamkuwa kapena zotchingira zamkuwa zotchingira kuti zitsekeretsedwe ndi ma electromagnetic ndikuwongolera luso loletsa kusokoneza.
Sheath Layer: Nthawi zambiri amapangidwa ndi fluoroplastics (mwachitsanzo, PFA, FEP) kapena mphira wa silikoni, wopereka kukana kutentha kwambiri, kukana dzimbiri, komanso kukana mafuta.
Zida Zankhondo: Mumitundu ina, tepi yachitsulo kapena zida za waya zitha kugwiritsidwa ntchito kukulitsa mphamvu zamakina ndi magwiridwe antchito.

3.Makhalidwe:

Kukanika kwa Kutentha Kwambiri: Kutentha kwakukulu kogwira ntchito, kufika ku 260 ° C, ngakhale 285 ° C m'mitundu ina.
Kulimbana ndi dzimbiri: Kutha kukana ma acid, alkalis, mafuta, madzi, ndi mpweya woipa wosiyanasiyana.
Kubwereranso kwa Flame: Imagwirizana ndi muyezo wa GB12666-90, kuwonetsetsa kuwonongeka kochepa pakayaka moto.
Kuthekera kwa Anti-Interference: Mapangidwe otchinga amachepetsa kusokoneza kwa ma elekitiroma, kuwonetsetsa kufalikira kwazizindikiro.

Kugwira Ntchito Mwachindunji ndi Ubwino Wakukanika Kwambiri Kutentha Kwambiri M'zingwe Zoteteza Kutentha Kwambiri

1.Kukana Kutentha Kwambiri:

Zingwe zotetezedwa ndi kutentha kwapamwamba zotsutsana ndi dzimbiri zimapangidwa ndi zida zapadera zomwe zimasunga ntchito yokhazikika m'malo otentha kwambiri. Mwachitsanzo, zingwe zina zimatha kugwira ntchito pa kutentha mpaka 200 ° C kapena kupitilira apo, zomwe zimapangitsa kuti zikhale zoyenera m'mafakitale otentha kwambiri monga mafuta, mankhwala, zitsulo, ndi mphamvu. Zingwezi zimapatsidwa chithandizo chapadera chakuthupi, kupereka kukhazikika kwabwino kwa kutentha ndi kukana kukalamba kapena kupunduka.

2.Kulimbana ndi Corrosion:

Zingwe zotetezedwa ndi kutentha kwapamwamba zolimbana ndi dzimbiri zimagwiritsa ntchito zida zolimbana ndi dzimbiri monga fluoroplastics ndi rabara ya silikoni, zomwe zimalimbana bwino ndi mpweya wowononga kapena zamadzimadzi m'malo otentha kwambiri ndikutalikitsa moyo wautumiki. Mwachitsanzo, zingwe zina zimatha kugwira ntchito m'malo oyambira -40 ° C mpaka 260 ° C.

3.Magwiridwe Amagetsi Okhazikika:

Zingwe zotetezedwa ndi kutentha kwapamwamba zolimbana ndi dzimbiri zimawonetsa zinthu zabwino kwambiri zotchinjiriza magetsi, zimatha kupirira ma voltages okwera, kuchepetsa kutayika kwa ma frequency apamwamba, ndikuwonetsetsa kutumiza ma siginecha odalirika. Kuphatikiza apo, mapangidwe awo otchinga amachepetsa kusokoneza kwa ma electromagnetic (EMI) ndi kusokoneza ma radio frequency (RFI), kuwonetsetsa kuti ma siginecha akhazikika komanso otetezeka.

4.Flame Retardancy and Safety Performance:

Zingwe zotetezedwa ndi kutentha kwapamwamba zoteteza ku dzimbiri nthawi zambiri zimagwiritsa ntchito zida zoletsa moto, zomwe zimalepheretsa kuyaka ngakhale kutentha kwambiri kapena kutentha kwambiri, motero kumachepetsa kuopsa kwa moto. Mwachitsanzo, zingwe zina zimagwirizana ndi muyezo wa GB 12660-90, zomwe zimapereka kukana moto wapamwamba.

5.Mechanical Mphamvu ndi Kukana Kukalamba:

Zingwe zotetezedwa ndi kutentha kwapamwamba zolimbana ndi dzimbiri zimakhala ndi mphamvu zamakina, zomwe zimawathandiza kupirira kupsinjika, kupindika, komanso kupsinjika. Panthawi imodzimodziyo, zida zawo zakunja zamkati zimakhala ndi kukana kukalamba, zomwe zimalola kugwiritsidwa ntchito kwa nthawi yayitali m'malo ovuta.

6.Wide Kugwiritsa:

Zingwe zotetezedwa ndi kutentha kwapamwamba zolimbana ndi dzimbiri ndizoyenera m'malo osiyanasiyana otentha komanso owononga, monga nyumba zokwera, malo opangira mafuta, malo opangira magetsi, migodi, ndi mafakitale amafuta. Mapangidwe awo ndi kusankha zinthu kumakwaniritsa zofunikira zapadera zamagulu osiyanasiyana a mafakitale.
