Chingwe cholumikizidwa ndi crosslinked ndi chidule cha chingwe cholumikizidwa ndi polyethylene (XL-PE) chotetezedwa. Zingwe zolumikizidwa ndi crosslinked ndizoyenera kugwiritsa ntchito mizere yotumizira ndi kugawa ndi magetsi amphamvu mpaka 500KV. Pakadali pano, zingwe zambiri zamagetsi amphamvu zimatetezedwa ndi polyethylene yolumikizidwa.
Zingwe zolumikizidwa nthawi zambiri zimatanthauza zingwe zomwe zimateteza ku kuzizira zimapangidwa ndi zinthu zolumikizidwa. Chinthu chomwe chimagwiritsidwa ntchito kwambiri ndi polyethylene yolumikizidwa (XLPE). Njira yolumikizirana ndi kupanga kapangidwe ka molekyulu ya polyethylene (PE) kudzera munjira inayake yopangira kuti apange mawonekedwe a kapangidwe ka mzere wolumikizirana wa polyethylene. Zotsatira zake, kutentha kovomerezeka kwa nthawi yayitali kumakwezedwa kuchokera pa 70℃ mpaka 90℃ (kapena kupitirira apo), ndipo kutentha kovomerezeka kwafupikitsa kumakwezedwa kuchokera pa 140℃ mpaka 250℃ (kapena kupitirira apo), zomwe zimapangitsa kuti magwiridwe antchito enieni azikhala bwino kwambiri chifukwa chosunga magwiridwe antchito ake abwino kwambiri.
Pali zabwino zingapo za XLPE. Wenchang amapereka mitundu yambiri ya XLPE yomwe mungasankhe.
Monga UL3265, UL3266, UL3167, UL3173, UL3182, UL3194, UL3195, UL3196, UL3199, UL3236 ndi zina zotero.
(1) Makhalidwe abwino kwambiri a makina ndi zakuthupi, kukana kupsinjika kwa chilengedwe, kukana kutopa kwambiri, kuposa PVC ndi PE zomwe zimatha kupirira kupsinjika kwakukulu kwa makina.
(2) Yolimba ku mankhwala osiyanasiyana osungunulira, yokhazikika m'malo osiyanasiyana owononga.
(3) M'mimba mwake wakunja wa waya wotetezedwa ndi polyolefin wolumikizidwa ndi radiation ndi wocheperako kuposa waya wotetezedwa ndi polyvinyl chloride wokhala ndi gawo lomwelo, zomwe zimatha kuchepetsa m'mimba mwake wa chitoliro womwe umagwiritsidwa ntchito popanga ulusi wa chitoliro, kapena kuvala mawaya ambiri pansi pa mulingo womwewo wa chitoliro, motero kuchepetsa mtengo wokhazikitsa.
(4) Chopangidwa ndi waya wotetezedwa ndi polyolefin wolumikizidwa ndi radiation ndi chopepuka kwambiri kuposa chopangidwa ndi waya wotetezedwa ndi PVC, chomwe chili chosavuta kuyika ndi mayendedwe, kuchepetsa mphamvu ya ogwira ntchito komanso ndalama zoyendera.
(5) Kutentha kwakukulu kwa waya wotetezedwa wolumikizidwa ndi radiation kumatha kufika 125℃ panthawi yogwira ntchito kwa nthawi yayitali, ndipo mphamvu yonyamulira ndi yayikulu kuposa waya wotetezedwa ndi PVC.
(6) Sichitulutsa mpweya wowononga kapena mpweya woopsa panthawi yoyaka, ndipo sichidzayambitsa kuwonongeka kwina. Ndi mtundu watsopano wa mankhwala oteteza chilengedwe mogwirizana ndi zofunikira zamakono zotetezera moto.
(7) Mphamvu yamagetsi yabwino, kukana kwa kutenthetsa kumakhala kwakukulu kwambiri kuposa chingwe cha PVC, ndipo kutayika kwapakati kwa Angle tangent ndi kochepa kwambiri, kwenikweni sikusintha ndi kusintha kwa kutentha.
