Tumira ImeyiliTambo dzemagetsi dzeXLPE dzine insulation yepakati nepakati dzakakodzera ma network ekugovera kana echipiri, dzinowanzo shanda sesimba guru remagetsi kuma network ezvekutengeserana, maindasitiri, uye emaguta. Dzinoshanda kuma system ane ma fault currents akakwira anosvika 10kA/1 second. Ma structures e fault currents akakwira anowanikwa kana akumbirwa. Akakodzera kushandiswa kwe static muvhu, mukati/kunze, muma ducts e cable, pasi pemvura, uye uko tambo dzisingapinzwe mu mechanical stress kana tensile strain. Nekuda kwe dielectric loss factor yayo yakaderera, iyo inogara yakadaro muhupenyu hwayo hwese, uye hunhu hwepamusoro hwe insulation hwe XLPE material, tambo iyi inoratidza kuvimbika kwakanyanya kushanda. Conductor shield uye semiconductor material insulation zvakabatana zvakachengeteka kwenguva refu (single-pass extrusion). Zvakakodzera substations, power stations, uye maindasitiri plants.
HV Cable Insulation XLPE ine zvakanakira zvinotevera:
1. Kushanda Kwekupisa:
XLPE ine chimiro chemativi matatu chakacheneswa ine simba rakanaka kwazvo rekudzivirira kupisa. Haiore kana kuita kabhoni pasi pe300℃, tembiricha yekushanda kwenguva refu inogona kusvika 90℃, uye hupenyu hwekupisa hunogona kusvika makore makumi mana.
2. Kushanda kweInsulation:
XLPE inochengetedza hunhu hwakanaka hwepakutanga hwekudzivirira kupisa kwePE, uye kuramba kwekudzivirira kupisa kunowedzera.
Kukosha kwayo kwe dielectric loss angle tangent kudiki kwazvo, uye hakukanganisike zvakanyanya nekupisa.
3. Zvimiro zveMichina:
Nekuda kwekuumbwa kwezvisungo zvitsva zvemakemikari pakati pemacromolecules, kuomarara, kuomarara, kuramba kukweshana, uye kuramba kukanganiswa kweXLPE zvakagadziridzwa, nokudaro zvichitsiva zvikanganiso zvePE izvo zvinogona kukanganiswa nezvakatipoteredza uye kutsemuka.
4. Hunhu hweKuramba kweChemical:
XLPE ine simba guru rekudzivirira asidhi nealkali uye mafuta, uye zvigadzirwa zvayo zvekutsva zvinonyanya kuva mvura necarbon dioxide, izvo zvisingakuvadzi nharaunda uye zvinosangana nezvinodiwa zvekuchengetedza moto kwemazuva ano.
Kuvaka:
Kuvaka:Triplex ine core imwe chete, core nhatu, 3×1-core.
Mutyairi:Mhangura kana aruminiyamu, yakatenderera yakavharirwa, yakatenderera yakamanikana.
Kudzivirira:XLPE kana TR-XLPE kana EPR.
Kudzivirira simbi:Chidziviriro chewaya yemhangura, chidziviriro chetepi yemhangura.
Muhara:Mupendero wesimbi we lead alloy, mupendero wealuminium wakakombama, mupendero wemhangura wakakombama.
Zvombo:Kudzivirira waya dzearuminiyamu (AWA), kudzivirira waya dzesimbi (SWA), kudzivirira waya dzesimbi dzisina ngura (SSWA).
Kureba kweTembiricha:
Tembiricha shoma yekuisa: 0°C
Kupisa kwakanyanya kushanda: +90°C
Tembiricha shoma yekushanda: -25°C
