I-Cable Insulation Materials: i-PVC, i-PE, kunye ne-XLPE - Uthelekiso oluneenkcukacha

Intshayelelo

Xa kuziwa ekwenzeni iintambo zombane, ukukhetha imathiriyeli efanelekileyo yokugquma kubalulekile. Uluhlu lwe-insulation alukhuseli kuphela ikhebula kumonakalo wangaphandle kodwa luqinisekisa nokusebenza kombane okukhuselekileyo nokusebenzayo. Phakathi kwezinto ezininzi ezikhoyo, i-PVC, i-PE, kunye ne-XLPE zezona zisetyenziswa ngokuqhelekileyo. Kodwa yintoni ebenza bahluke, kwaye unquma njani ukuba yeyiphi eyona ilungele iimfuno zakho? Masingene kwiinkcukacha ngendlela elula, ekulula ukuyiqonda.

Isishwankathelo seMathiriyeli yeInsulation nganye

I-PVC (iPolyvinyl Chloride)

I-PVC luhlobo lweplastiki eyenziwe nge-polymerized vinyl chloride. Isebenza ngeendlela ezininzi kwaye isetyenziswa ngokubanzi kumashishini ahlukeneyo. Kwiintambo, iPVC ibalasele kuba izinzile, yomelele, kwaye iyamelana neeasidi, iialkali, kunye nokuguga.

• I-PVC ethambileyo: I-Flexible kwaye isetyenziswa ngokuqhelekileyo ukwenza izinto zokupakisha, iifilimu, kunye neengqimba ze-insulation kwiintambo ze-low-voltage. Imizekelo ibandakanya iintambo zamandla ezinjongo ngokubanzi.
• I-PVC eqinile: Iqinile kwaye isetyenziselwa ukwenza imibhobho kunye neepaneli.

Enye yezona zinto zibalaseleyo zePVC kukuxhathisa kwayo kwidangatye, nto leyo eyenza ukuba idume kwiintambo ezikwaziyo ukumelana nomlilo. Nangona kunjalo, inecala elisezantsi: xa itshisiwe, ikhupha umsi onetyhefu kunye neegesi ezidliwayo.

I-PE (iPolyethylene)

I-PE yinto engeyiyo ityhefu, i-lightweight material eyenziwe nge-polymerizing ethylene. Idume ngeempawu zayo zokugquma umbane ezibalaseleyo kunye nokumelana neekhemikhali kunye nokufuma. I-PE ilungile ngokukhethekileyo ekuphatheni amaqondo obushushu aphantsi kwaye ine-dielectric engaguqukiyo, enciphisa ukulahleka kwamandla.

Ngenxa yezi mpawu, i-PE ihlala isetyenziselwa ukugquma iintambo zombane ezinombane ophezulu, iintambo zedatha, kunye neengcingo zonxibelelwano. Ifanelekile kwizicelo apho ukusebenza kombane kubaluleke kakhulu, kodwa ayisiyiyo ukumelana nedangatye njengePVC.

I-XLPE (iPolyethylene edityaniswe ngokunqamlezileyo)

I-XLPE luhlobo oluphuculweyo lwe-PE. Yenziwe ngeekhemikhali okanye ngokwasemzimbeni iimolekyuli ze-polyethylene ezidibanisayo, eziphucula kakhulu iimpawu zayo.

Xa kuthelekiswa ne-PE eqhelekileyo, i-XLPE inikezela ngokuxhathisa ubushushu obungcono, amandla aphezulu oomatshini, kunye nokuqina okuphezulu. Ikwayakwazi ukumelana namanzi kunye nemitha, iyenze ilungele izicelo ezibango ezinje ngeentambo eziphantsi komhlaba, amaziko ombane enyukliya, kunye nemekobume yaselwandle.

Umahluko oPhambili phakathi kwePVC, PE, kunye neXLPE

1. Ukusebenza kweThermal

• I-PVC: Ifanelekile kwiindawo eziphantsi kobushushu kodwa inokunyamezela ubushushu obulinganiselweyo. Ayilunganga kwizicelo ezifuna ukumelana nobushushu obuphezulu.
• PE: Ibamba amaqondo obushushu aphakathi kakuhle kodwa iqala ukuthotywa phantsi kobushushu obugqithisileyo.
• XLPE: Ii-Excels kwiindawo ezinobushushu obuphezulu. Iyakwazi ukusebenza ngokuqhubekayo kwi-125 ° C kwaye imelane nokushisa kwexesha elifutshane ukuya kwi-250 ° C, iyenza iphelele kwizicelo zoxinzelelo oluphezulu.

2. IiPropati zoMbane

• I-PVC: Iipropati zombane ezilungileyo zokusetyenziswa ngokubanzi.
• PE: Ukufakelwa kombane okugqwesileyo kunye nokulahlekelwa kwamandla aphantsi, okufanelekileyo kwi-high-frequency okanye izicelo eziphezulu ze-voltage.
• XLPE: Igcina iipropathi zombane ezigqwesileyo ze-PE ngelixa unikezela ukusebenza okungcono phantsi kobushushu obuphezulu.

3. Ukuqina kunye nokuguga

• I-PVC: Utyekelo lokuguga ngokuhamba kwexesha, ngakumbi kwiindawo ezinobushushu obuphezulu.
• PE: Ukuchasa ngcono ukuguga kodwa kungabi namandla njenge-XLPE.
• XLPE: Ukuchasana okugqwesileyo kokuguga, uxinzelelo lokusingqongileyo, kunye nokunxitywa koomatshini, okwenza kube lukhetho oluhlala ixesha elide.

4. Ukhuseleko loMlilo

• I-PVC: Ayinamlilo kodwa ikhupha umsi onetyhefu neegesi xa utshisiwe.
• PE: Ayinatyhefu kodwa inokutsha, ngoko ayilona khetho lungcono kwiindawo ezinomlilo.
• XLPE: Ifumaneka kwi-low-smoke, i-halogen-free variants, eyenza ikhuseleke kwiimeko zomlilo.

5. Iindleko

• I-PVC: Olona khetho lufikelelekayo, olusetyenziswa ngokubanzi kwiintambo zenjongo jikelele.
• PE: Iyabiza kancinci ngenxa yeempawu zayo eziphezulu zombane.
• XLPE: Elona xabiso liphezulu kodwa lixabisa ixabiso eliphezulu lokusebenza okanye izicelo ezibalulekileyo.
