Ndikukula kosalekeza kwa kulumikizana kwa ma netiweki komanso kuwongolera kosalekeza kwa bandwidth yotumizira, zingwe zama data zomwe zimagwiritsidwa ntchito pamanetiweki olumikizirana nawonso zikukula mosalekeza kupita ku bandwidth yapamwamba yotumizira. Pakalipano, Cat.6A ndi zingwe zapamwamba za data zakhala zogwiritsidwa ntchito pa intaneti. Kuti akwaniritse ntchito yabwino yotumizira, zingwe za data zotere ziyenera kukhala zotsekera thovu.
Ma PE omwe ali ndi thovu lopaka thovu ndi chingwe chotchinga chopangidwa ndi utomoni wa HDPE monga maziko, ndikuwonjezera kuchuluka koyenera kwa ma nucleating agent ndi zowonjezera zina, ndikusinthidwa ndikusakaniza, pulasitiki, ndi granulating.
Ndikoyenera kutengera ukadaulo wotulutsa thovu womwe ndi njira yobaya mpweya woponderezedwa (N2 kapena CO2) mupulasitiki yosungunuka ya PE kuti ipange thovu lotsekeka. Poyerekeza ndi kusungunula kolimba kwa PE, pambuyo pochita thovu, kukhazikika kwa dielectric kwazinthu kumachepetsedwa; kuchuluka kwa zinthu kumachepetsedwa, ndipo mtengo wake umachepetsedwa; kulemera kwafupika; ndipo kutsekemera kwa kutentha kumalimbikitsidwa.
Mankhwala a OW3068/F omwe timapereka ndi zinthu zoteteza thovu zomwe zimagwiritsidwa ntchito makamaka popanga wosanjikiza wa thovu la data. Maonekedwe ake ndi opepuka achikasu a cylindrical compounds okhala ndi kukula kwa (φ2.5mm~φ3.0mm)×(2.5mm~3.0mm).
Pakupanga, kuchuluka kwa thovu lazinthu kumatha kuwongoleredwa ndi njira, ndipo digiri ya thovu imatha kufika pafupifupi 70%. Madigiri osiyanasiyana othovutsa amatha kupeza ma dielectric osiyanasiyana, kuti zinthu za chingwe cha data zitha kuchepetsedwa pang'ono, kutsika kwapang'onopang'ono, komanso kugwiritsa ntchito bwino magetsi.
Chingwe cha data chomwe chimapangidwa ndi ma OW3068/F PE athu okhala ndi thovu lotsekera amatha kukwaniritsa zofunikira za IEC61156, ISO11801, EN50173 ndi miyezo ina.
Ma PE okhala ndi thovu lotsekera pazingwe zama data omwe timapereka ali ndi izi:
1) yunifolomu tinthu kukula popanda zosafunika;
2) Oyenera mkulu-liwiro kutchinjiriza extruding, liwiro extruding akhoza kufika oposa 1000m/mphindi;
3) Ndi zinthu zabwino kwambiri zamagetsi. Dielectric nthawi zonse imakhala yokhazikika pamaulendo osiyanasiyana, kutayika kwa dielectric tangent ndi kochepa, ndipo mphamvu ya resistivity ndi yaikulu, yomwe ingatsimikizire kukhazikika ndi kusasinthasintha kwa magwiridwe antchito panthawi yotumizira mafupipafupi;
4) Ndi zinthu zabwino kwambiri zamakina, zomwe sizili zophweka kufinyidwa ndi kupunduka panthawi ya extrusion ndi kukonza kotsatira.
Ndizoyenera kupanga chingwe cha thovu cha waya wapakatikati wa Cat.6A, Cat.7, Cat.7A ndi Cat.8 data.

1) Zogulitsazo ziyenera kusungidwa m'nyumba yosungiramo zinthu zoyera, zaukhondo, zowuma komanso mpweya wabwino, ndipo zisamangidwe ndi zinthu zoyaka moto, ndipo zisakhale pafupi ndi gwero lamoto;
2) mankhwala ayenera kupewa dzuwa ndi mvula;
3) Zogulitsazo ziyenera kupakidwa bwino, pewani chinyezi komanso kuipitsidwa;

Kulongedza nthawi zonse: thumba la pulasitiki la pepala la thumba lakunja, thumba la filimu la PE la thumba lamkati. Zomwe zili m'thumba lililonse ndi 25kg.
Kapena njira zina zoyikamo zomwe zakambidwa ndi onse awiri.
