Tumizani ImeloChingwe chogawa magetsi kapena sub-transmission network chomwe chimagwiritsidwa ntchito ngati choyambira ku Commercial, Industrial and network networking.Yoyenera pamakina olakwika okwera mpaka 10kA/1sec.Zomangamanga zomwe zidavoteredwa ndi zolakwika zapamwamba zimapezeka mukafunsidwa.
Kutentha:
Kutentha kochepa koyika: 0°C
Kutentha kwakukulu kogwira ntchito: +90 ° C
Kutentha kochepa kogwira ntchito: -25 °C
Malo ocheperako opindika
Zingwe zoyikidwa: 12D (PVC yokha) 15D (HDPE)
Pa unsembe: 18D (PVC yekha) 25D (HDPE)
Kukaniza kukhudzidwa ndi Chemical: Mwangozi
Kukokera pamakina: Kuwala (PVC kokha) Kulemera (HDPE)
Kuwonekera kwamadzi: XLPE - Spray EPR - Kumiza / Kuphimba kwakanthawi
Kutentha kwadzuwa komanso kukhudzana ndi nyengo: Koyenera kuwonetseredwa mwachindunji.
Zomanga:
Opangidwa ndi Mtundu Woyesedwa AS/NZS 1429.1, IEC: 60502-2 ndi miyezo ina yoyenera
Mapangidwe - 1 pachimake, 3 pachimake, 3 × 1 pachimake Triplex
Kondakitala - Cu kapena AL, Zozungulira Zozungulira, Zozungulira Zozungulira, Milliken Yogawidwa
Insulation - XLPE kapena TR-XLPE kapena EPR
Chojambula chachitsulo kapena sheath - Copper Wire Screen (CWS), Copper Tape Screen (CTS), lead alloy sheath (LAS), Corrugated Aluminium sheath (CAS), Corrugated Copper sheath (CCU), Corrugated Stainless Steel (CSS), Aluminium poly laminated (APL), Copper Poly Laminated (CPL), Aldrey wire screen (AWS)
Zida - Aluminium Wire Armored (AWA), Steel Wire Armored (SWA), Stainless Steel Wire Armored (SSWA)
Polyethylene (HDPE) akunja - njira ina
Utsi wochepa zero halogen (LSOH) - njira ina
HV Cable Insulation XLPE ili ndi zotsatirazi:
1. Heat Resistance Performance:
XLPE yokhala ndi mawonekedwe atatu-dimensional ili ndi ntchito yabwino kwambiri yokana kutentha.Sichidzawola ndi carbonize pansi pa 300 ℃, kutentha kwa nthawi yayitali kumatha kufika 90 ℃, ndipo moyo wotentha ukhoza kufika zaka 40.
2. Ntchito ya Insulation:
XLPE imasunga zoyambira zabwino zotchinjiriza za PE, ndipo kukana kwa insulation kumachulukirachulukira.
Mtengo wake wa dielectric loss angle tangent ndiwochepa kwambiri, ndipo sukhudzidwa kwambiri ndi kutentha.
3.Mechanical Properties:
Chifukwa cha kukhazikitsidwa kwa zomangira zatsopano zamakina pakati pa ma macromolecules, kuuma, kuuma, kukana kwa abrasion, komanso kukana kwa XLPE kwasinthidwa, motero kumapanga zophophonya za PE zomwe zimatha kukhudzidwa ndi kupsinjika kwa chilengedwe komanso kusweka.
4.Makhalidwe Otsutsana ndi Chemical:
XLPE ili ndi asidi amphamvu ndi kukana kwa alkali ndi kukana kwa mafuta, ndipo zopangira zake zoyaka zimakhala ndi madzi ndi carbon dioxide, zomwe siziwononga chilengedwe komanso zimakwaniritsa zofunikira za chitetezo chamakono chamoto.
