Thumela i-imeyileIintambo zamandla ze-XLPE ezifakwe i-insulation ye-XLPE eziyi-6.35-11kV zifanelekile kwiinethiwekhi zokusasaza okanye zesibini, zihlala zisebenza njengombane ophambili kwiinethiwekhi zorhwebo, zoshishino, kunye neendawo zokuhlala zasezidolophini. Zisebenza kwiinkqubo ezinee-currents eziphezulu ezilinganiselwe ukuya kwi-10kA/1 second. Izakhiwo ze-currents eziphezulu ezilinganiselweyo ziyafumaneka xa ziceliwe. Zifanelekile ukusetyenziswa okungaguqukiyo emhlabeni, ngaphakathi/ngaphandle, kwii-cable ducts, ezingaphantsi kwamanzi, kwaye apho iintambo zingafakwanga kuxinzelelo olukhulu loomatshini okanye uxinzelelo lokuxinana. Ngenxa ye-dielectric loss factor yayo ephantsi kakhulu, ehlala ihleli kuyo yonke impilo yayo yokusebenza, kunye neempawu zokukhusela eziphezulu zezinto ze-XLPE, le ntambo ibonisa ukuthembeka okuphezulu kokusebenza. I-conductor shield kunye ne-semiconductor material insulation zihlanganiswe ngokukhuselekileyo ixesha elide (i-single-pass extrusion). Zifanelekile kwizikhululo zamandla, kwizikhululo zamandla, nakwizityalo zoshishino.
I-HV Cable Insulation XLPE inezi nzuzo zilandelayo:
1. Ukusebenza kokumelana nobushushu:
I-XLPE enesakhiwo esineemilinganiselo ezintathu esilungisiweyo inamandla amahle kakhulu okumelana nobushushu. Ayiyi kubola kwaye ingabi yi-carbonize ngaphantsi kwe-300℃, ubushushu bokusebenza bexesha elide bunokufikelela kwi-90℃, kwaye ubomi bobushushu bunokufikelela kwiminyaka engama-40.
2. Ukusebenza kwe-Insulation:
I-XLPE igcina iimpawu zokuqala zokugquma ezilungileyo ze-PE, kwaye ukumelana nokugquma kuyanda ngakumbi.
Ixabiso layo le-dielectric loss angle tangent lincinci kakhulu, kwaye alichaphazeleki kakhulu bubushushu.
3. Iipropati zoomatshini:
Ngenxa yokusekwa kweebhondi ezintsha zeekhemikhali phakathi kwee-macromolecules, ubulukhuni, ukuqina, ukumelana nokukrweleka, kunye nokumelana nempembelelo ye-XLPE kuye kwaphuculwa, ngaloo ndlela kulungiswa iintsilelo ze-PE ezichaphazeleka lula kuxinzelelo lokusingqongileyo kunye nokuqhekeka.
4. Iimpawu zokuxhathisa iikhemikhali:
I-XLPE inokumelana okunamandla kwe-asidi kunye ne-alkali kunye nokumelana neoyile, kwaye iimveliso zayo zokutsha ikakhulu ngamanzi kunye ne-carbon dioxide, ezingonakalisi kangako kwindalo esingqongileyo kwaye zihlangabezana neemfuno zokhuseleko lomlilo lwanamhlanje.
