Mafakitale Oteteza Thupi Opangidwa ndi Thovu la PE
Chiyambi cha Zamalonda
Ndi chitukuko chopitilira cha kulumikizana kwa netiweki komanso kupititsa patsogolo kwa bandwidth yotumizira mauthenga, zingwe za data zomwe zimagwiritsidwa ntchito mu netiweki yolumikizirana zikukulirakulirabe kukhala bandwidth yotumizira mauthenga. Pakadali pano, zingwe za Cat.6A ndi zingwe za data zapamwamba zakhala zinthu zazikulu zolumikizira ma netiweki. Kuti zigwire bwino ntchito yotumizira mauthenga, zingwe za data zotere ziyenera kugwiritsa ntchito kutchinjiriza kwa thovu.
Ma PE physical thovu insulation compounds ndi zinthu zotetezera kutentha zomwe zimapangidwa ndi HDPE resin ngati maziko, zomwe zimawonjezera kuchuluka koyenera kwa nucleating agent ndi zina zowonjezera, ndipo zimakonzedwa mwa kusakaniza, pulasitiki, ndi granulating.
Ndikoyenera kugwiritsa ntchito ukadaulo wopangira thovu womwe ndi njira yolowetsa mpweya wopanikizika (N2 kapena CO2) mu pulasitiki yosungunuka ya PE kuti ipange thovu lotsekedwa. Poyerekeza ndi kutchinjiriza kolimba kwa PE, pambuyo pothira thovu, mphamvu ya dielectric ya chinthucho idzachepetsedwa; kuchuluka kwa zinthuzo kumachepetsedwa, ndipo mtengo wake umachepetsedwa; kulemera kwake kumachepetsedwa; ndipo kutchinjiriza kutentha kumalimbikitsidwa.
Ma compound a OW3068/F omwe timapereka ndi zinthu zotetezera thovu zomwe zimagwiritsidwa ntchito makamaka popanga chotetezera thovu cha data cable. Mawonekedwe ake ndi achikasu opepuka okhala ndi mawonekedwe a cylindrical okhala ndi kukula kwa (φ2.5mm～φ3.0mm)×(2.5mm～3.0mm).
Pa nthawi yopangira, kuchuluka kwa thovu la zinthuzo kumatha kulamulidwa ndi njira yopangira, ndipo kuchuluka kwa thovu kumatha kufika pafupifupi 70%. Madigiri osiyanasiyana a thovu amatha kupeza ma dielectric constants osiyanasiyana, kotero kuti zinthu za data cable zitha kuchepetsa kuchepa kwa mphamvu, kuchuluka kwa mphamvu yotumizira, komanso magwiridwe antchito abwino otumizira magetsi.
Chingwe cha data chomwe chimapangidwa ndi OW3068/F PE yathu yoteteza ku fumbi imatha kukwaniritsa zofunikira za IEC61156, ISO11801, EN50173 ndi miyezo ina.
makhalidwe
Ma PE physical thovu insulating compounds a ma data cables omwe timapereka ali ndi makhalidwe awa:
1) Kukula kwa tinthu tofanana popanda zonyansa;
2) Yoyenera kutulutsa kutentha kwachangu kwambiri, liwiro lotulutsa kutentha limatha kufika pa 1000m/min;
3) Ndi mphamvu zamagetsi zabwino kwambiri. Chokhazikika cha dielectric chimakhala chokhazikika pama frequency osiyanasiyana, kutayika kwa dielectric kumakhala kochepa, ndipo kukana kwa voliyumu kumakhala kwakukulu, zomwe zingatsimikizire kukhazikika ndi kusinthasintha kwa magwiridwe antchito panthawi yotumizira ma frequency apamwamba;
4) Ndi mphamvu zabwino kwambiri zamakanika, zomwe sizili zosavuta kuzifinya ndikuzisintha panthawi yotulutsa ndi kukonza pambuyo pake.
Kugwiritsa ntchito
Ndi yoyenera kupanga waya wa Cat.6A, Cat.7, Cat.7A ndi Cat.8 data cable yokhala ndi thovu.

Njira Yosungira
1) Chogulitsacho chiyenera kusungidwa m'nyumba yosungiramo zinthu yoyera, yaukhondo, youma komanso yodutsa mpweya, ndipo sichiyenera kuyikidwamo zinthu zoyaka moto, ndipo sichiyenera kukhala pafupi ndi komwe moto umachokera;
2) Chogulitsacho chiyenera kupewa kuwala kwa dzuwa ndi mvula;
3) Chogulitsacho chiyenera kupakidwa bwino, kupewa chinyezi ndi kuipitsidwa;
4) Kutentha kwa zinthuzo kuyenera kukhala kochepera 50℃.
Kulongedza
Kulongedza kwanthawi zonse: thumba la pepala-pulasitiki lopangidwa ndi zinthu zosiyanasiyana la thumba lakunja, thumba la filimu ya PE la thumba lamkati. Kuchuluka kwa thumba lililonse ndi 25kg.
Kapena njira zina zopakira zomwe zimakambidwa ndi onse awiri.
