Imitha yelanga kunye nokuba sesichengeni semozulu: Ilungele ukuvezwa ngokuthe ngqo.
Ulwakhiwo:
Yenziwe kunye noHlobo oluvavanyiweyo lwe-AS / NZS 1429.1, IEC: 60502-2 kunye neminye imigangatho esebenzayo
Ukuqulunqwa - i-1 core, i-3 core, i-3 × i-1 i-core Triplex
I-Conductor-Cu okanye i-AL, iSetyhula ene-Stranded, i-Stranded Compact Circular, i-Milliken iSegmented
I-Insulation - i-XLPE okanye i-TR-XLPE okanye i-EPR
Isikrini seMetallic okanye i-sheath - iCopper Wire Screen (CWS), iCopper Tape Screen (CTS), i-Lead alloy sheath (LAS), i-Corrugated Aluminium sheath (CAS), i-Corrugated Copper sheath (CCU), i-Corrugated Stainless Steel (CSS), i-Aluminium poly laminated (APL), Copper Poly Laminated (CPL), Aldrey wire screen (AWS)
Isikrweqe – iAluminiyam yocingo oluxhobileyo (AWA), ucingo lwentsimbi oluxhotyisiweyo (i-SWA), iSikhali esineSikhali esixhotyisiweyo socingo (SSWA)
I-Polyethylene (HDPE) yangaphandle - enye indlela
Umsi ophantsi we-zero halogen (LSOH) - enye indlela
I-HV Cable Insulation XLPE inezi zibonelelo zilandelayo:
1.Ukusebenza kokumelana nobushushu:
I-XLPE ene-reticulated ezintathu-dimensional structure inomsebenzi ogqwesileyo wokumelana nobushushu.Ayiyi kubola kwaye i-carbonize ngaphantsi kwe-300 ℃, ukushisa kwexesha elide lokusebenza kunokufikelela kwi-90 ℃, kwaye ubomi be-thermal bunokufikelela kwiminyaka engama-40.
2.Ukusebenza kweInsulation:
I-XLPE igcina iimpawu zoqobo zokugquma kwe-PE, kwaye ukuchasana kokugquma kuyanda.
Ixabiso layo le-dielectric loss angle tangent lincinci kakhulu, kwaye alichatshazelwa kakhulu ngubushushu.
3.iiPropati zoomatshini:
Ngenxa yokusekwa kwamabhondi amatsha emichiza phakathi kwama-macromolecules, ukuqina, ukuqina, ukunyanzeliswa kwe-abrasion, kunye nokuchasana kwempembelelo ye-XLPE kuye kwaphuculwa, ngaloo ndlela yenzela ukusilela kwe-PE enokuthi ichaphazele uxinzelelo lwendalo kunye nokuqhekeka.
4.IiMpawu zokuNxhathisa iChemical:
I-XLPE ine-asidi eyomeleleyo kunye nokumelana ne-alkali kunye nokuxhathisa i-oyile, kwaye iimveliso zayo zokutsha zingamanzi kunye ne-carbon dioxide, ezingenabungozi kangako kwindalo kwaye zihlangabezana neemfuno zokhuseleko lomlilo lwanamhlanje.
