Cable Insulation Materials: PVC, PE, ndi XLPE - Kufananitsa Mwatsatanetsatane

Mawu Oyamba

Zikafika popanga zingwe zamagetsi, kusankha zotchingira zoyenera ndikofunikira. Kuyika kwazitsulo sikumangoteteza chingwe ku kuwonongeka kwakunja komanso kumatsimikizira kuti magetsi akuyenda bwino komanso otetezeka. Pazinthu zambiri zomwe zilipo, PVC, PE, ndi XLPE ndizo zomwe zimagwiritsidwa ntchito kwambiri. Koma nchiyani chimawapangitsa kukhala osiyana, ndipo mumasankha bwanji kuti ndi yabwino kwa zosowa zanu? Tiyeni tilowe mwatsatanetsatane m'njira yosavuta, yosavuta kumvetsetsa.

Chidule cha Insulation Material Iliyonse

PVC (Polyvinyl Chloride)

PVC ndi mtundu wa pulasitiki wopangidwa kuchokera ku polymerized vinyl chloride. Ndiwosinthika kwambiri ndipo amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Pazingwe, PVC ndi yodziwika bwino chifukwa ndi yokhazikika, yolimba, komanso yosamva ma asidi, alkali, ndi ukalamba.

• PVC yofewa: Zosinthika komanso zomwe zimagwiritsidwa ntchito popanga zida zonyamula, mafilimu, ndi zigawo zotchingira mu zingwe zotsika mphamvu. Zitsanzo ndi zingwe zamagetsi zomwe zimagwiritsidwa ntchito nthawi zonse.
• Zithunzi za PVC: Cholimba komanso chogwiritsidwa ntchito popanga mapaipi ndi mapanelo.

Chimodzi mwazinthu zabwino kwambiri za PVC ndikukana kwamoto, zomwe zimapangitsa kuti zikhale zodziwika bwino pazingwe zosagwira moto. Komabe, ili ndi zoyipa zake: ikawotchedwa, imatulutsa utsi wapoizoni ndi mpweya wowononga.

PE (Polyethylene)

PE ndi chinthu chopanda poizoni, chopepuka chopangidwa ndi polymerizing ethylene. Ndiwotchuka chifukwa cha mphamvu zake zotchinjiriza zamagetsi komanso kukana mankhwala ndi chinyezi. PE ndi yabwino kwambiri pakugwira kutentha kwapansi ndipo imakhala ndi dielectric yotsika, yomwe imachepetsa kutaya mphamvu.

Chifukwa cha makhalidwe amenewa, PE nthawi zambiri amagwiritsidwa ntchito potsekera zingwe zamagetsi zothamanga kwambiri, zingwe za data, ndi mawaya olumikizirana. Ndiwoyenera kugwiritsa ntchito pomwe magetsi ndi ofunika kwambiri, koma sizogwira moto ngati PVC.

XLPE (Polyethylene Yophatikizika)

XLPE kwenikweni ndi mtundu wokwezedwa wa PE. Amapangidwa ndi mamolekyu a polyethylene omwe amalumikizana ndi mankhwala kapena mwakuthupi, omwe amawongolera kwambiri zinthu zake.

Poyerekeza ndi PE wamba, XLPE imapereka kukana kutentha kwabwino, mphamvu zamakina apamwamba, komanso kulimba kwambiri. Imathanso kugonjetsedwa ndi madzi ndi ma radiation, zomwe zimapangitsa kuti ikhale yabwino kugwiritsa ntchito ngati zingwe zapansi panthaka, malo opangira magetsi a nyukiliya, ndi malo am'madzi.

Kusiyana Kwakukulu Pakati pa PVC, PE, ndi XLPE

1. Thermal Magwiridwe

• Zithunzi za PVC: Oyenera kumadera otsika kutentha koma ali ndi kulekerera kutentha kochepa. Si yabwino kwa mapulogalamu omwe amafunikira kutentha kwambiri.
• PE: Imagwira bwino kutentha kwapakati koma imayamba kutsika pansi pa kutentha kwakukulu.
• Zithunzi za XLPE: Excels m'malo otentha kwambiri. Imatha kugwira ntchito mosalekeza pa 125 ° C ndikupirira kutentha kwakanthawi kochepa mpaka 250 ° C, ndikupangitsa kuti ikhale yabwino pamapulogalamu opsinjika kwambiri.

2. Zida Zamagetsi

• Zithunzi za PVC: Good magetsi katundu ntchito wamba.
• PE: Kusungunula kwamagetsi kwabwino kwambiri komwe kumataya mphamvu zochepa, koyenera kugwiritsa ntchito ma frequency apamwamba kapena ma voliyumu apamwamba.
• Zithunzi za XLPE: Imasunga mphamvu zamagetsi za PE zabwino kwambiri pomwe ikupereka magwiridwe antchito bwino pansi pa kutentha kwambiri.

3. Kukhalitsa ndi Kukalamba

• Zithunzi za PVC: Amakonda kukalamba pakapita nthawi, makamaka m'malo otentha kwambiri.
• PE: Kukana bwino kukalamba koma osalimba ngati XLPE.
• Zithunzi za XLPE: Kukana kwambiri kukalamba, kupsinjika kwa chilengedwe, komanso kuvala kwamakina, zomwe zimapangitsa kukhala chisankho chokhalitsa.

4. Chitetezo cha Moto

• Zithunzi za PVC: Imawotcha koma imatulutsa utsi wapoizoni komanso mpweya woipa ukapsa.
• PE: Zopanda poizoni koma zoyaka, kotero sizomwe zili bwino kwambiri kumadera omwe amatha kupsa ndi moto.
• Zithunzi za XLPE: Imapezeka mumitundu yotsika utsi, yopanda halogen, zomwe zimapangitsa kuti zikhale zotetezeka pakayaka moto.

5. Mtengo

• Zithunzi za PVC: Njira yotsika mtengo kwambiri, yomwe imagwiritsidwa ntchito kwambiri pazingwe zopangira wamba.
• PE: Zokwera mtengo pang'ono chifukwa champhamvu zake zamagetsi.
• Zithunzi za XLPE: Zokwera mtengo kwambiri koma zotsika mtengo kwambiri pazochita zapamwamba kapena zovuta.

Kugwiritsa ntchito PVC, PE, ndi XLPE mu Zingwe

Mapulogalamu a PVC

• Zingwe zamagetsi zotsika mphamvu
• Mawaya acholinga chonse
• Zingwe zosagwira moto zomwe zimagwiritsidwa ntchito pomanga nyumba ndi mafakitale

Mapulogalamu a PE

• Zingwe zamagetsi zamphamvu kwambiri
• Zingwe za data zamakompyuta ndi maukonde olumikizirana
• Zizindikiro ndi mawaya owongolera

Mapulogalamu a XLPE

• Zingwe zotumizira mphamvu, kuphatikiza zingwe zapansi panthaka ndi zapansi pamadzi
• Malo otentha kwambiri ngati malo opangira magetsi a nyukiliya
• Zokonda zama mafakitale komwe kukhazikika ndi chitetezo ndizofunikira

Kuyerekeza kwa XLPO ndi XLPE

XLPO (Polyolefin Yophatikizika)

• Amapangidwa kuchokera ku ma olefin osiyanasiyana, kuphatikiza ma EVA ndi ma halogen opanda mankhwala.
• Amadziwika chifukwa cha utsi wochepa komanso wopanda halogen, zomwe zimapangitsa kuti azikhala okonda zachilengedwe.

XLPE (Polyethylene Yophatikizika)

• Imayang'ana pa polyethylene cross-linking kuti ipititse patsogolo kulimba komanso kukana kutentha.
• Ndibwino kuti mugwiritse ntchito kupsinjika kwambiri, kutentha kwambiri.

Ngakhale zida zonse ziwirizi ndizolumikizana, XLPO ndiyoyenera kugwiritsa ntchito zachilengedwe komanso utsi wochepa, pomwe XLPE imawala m'mafakitale komanso magwiridwe antchito apamwamba.

Mapeto

Kusankha zinthu zotchinjiriza chingwe kumadalira zosowa zanu zenizeni. PVC ndi chisankho chotsika mtengo chogwiritsidwa ntchito wamba, PE imapereka magwiridwe antchito apamwamba kwambiri amagetsi, ndipo XLPE imapereka kulimba kosayerekezeka ndi kukana kutentha pazofuna zambiri. Pomvetsetsa kusiyana pakati pa zipangizozi, mukhoza kupanga zisankho zodziwika bwino kuti mutsimikizire chitetezo, ntchito, ndi moyo wautali mu makina anu a chingwe.

Danyang Winpower Wire and Cable Mfg Co., Ltd.Wopanga zida zamagetsi ndi zinthu, zinthu zazikuluzikulu zimaphatikizapo zingwe zamagetsi, zolumikizira ma waya ndi zolumikizira zamagetsi. Amagwiritsidwa ntchito pamakina anzeru apanyumba, makina a photovoltaic, makina osungira mphamvu, ndi makina amagalimoto amagetsi
