Tumizani ImeloZingwe zamagetsi za 6.35-11kV XLPE-insulated medium-voltage ndi zoyenera kugwiritsidwa ntchito pa maukonde ogawa kapena ma transmission, nthawi zambiri zimakhala ngati magetsi akuluakulu a maukonde amalonda, mafakitale, ndi mizinda. Zimagwiritsidwa ntchito pamakina omwe ali ndi ma current amphamvu kwambiri omwe amafika pa 10kA/1 sekondi. Mapangidwe a ma current amphamvu kwambiri amapezeka akapemphedwa. Oyenera kugwiritsidwa ntchito mosasunthika pansi, m'nyumba/kunja, m'machubu a chingwe, m'madzi, komanso komwe maukonde sakhudzidwa ndi kupsinjika kwakukulu kwa makina kapena kupsinjika kwa tensile. Chifukwa cha kuchepa kwake kwa dielectric loss factor, komwe kumakhalabe kosasintha nthawi yonse ya moyo wake, komanso mphamvu zabwino kwambiri zotetezera za XLPE, chingwechi chimagwira ntchito modalirika kwambiri. Chishango cha conductor ndi semiconductor material insulation zimalumikizidwa bwino kwambiri (single-pass extrusion). Zoyenera kugwiritsidwa ntchito pa substations, ma power station, ndi mafakitale.
HV Cable Insulation XLPE ili ndi ubwino wotsatira:
1. Kukana Kutentha:
XLPE yokhala ndi mawonekedwe atatu ozungulira imakhala ndi mphamvu yabwino kwambiri yolimbana ndi kutentha. Siidzawola ndi kuwononga mpweya pansi pa 300℃, kutentha kwa nthawi yayitali kumatha kufika 90℃, ndipo nthawi yogwira ntchito yotentha imatha kufika zaka 40.
2. Kuteteza Kutenthetsa:
XLPE imasunga mawonekedwe abwino oyambira a PE, ndipo kukana kwa kutchinjiriza kumawonjezeka kwambiri.
Mtengo wake wa dielectric loss angle tangent ndi wochepa kwambiri, ndipo sukhudzidwa kwambiri ndi kutentha.
3. Katundu wa Makina:
Chifukwa cha kukhazikitsidwa kwa ma bond atsopano a mankhwala pakati pa ma macromolecules, kuuma, kuuma, kukana kukwawa, ndi kukana kukhudzidwa kwa XLPE kwakhala bwino, motero kubwezera zofooka za PE zomwe zimakhala zosavuta kupsinjika ndi kusweka kwa chilengedwe.
4. Makhalidwe Otsutsana ndi Mankhwala:
XLPE ili ndi mphamvu yolimba ya asidi ndi alkali komanso kukana mafuta, ndipo zinthu zomwe zimayaka makamaka ndi madzi ndi carbon dioxide, zomwe siziwononga chilengedwe ndipo zimakwaniritsa zofunikira za chitetezo chamakono pamoto.
Kapangidwe kake:
Kapangidwe kake:Triplex ya core imodzi, core zitatu, 3×1-core.
Woyendetsa:Mkuwa kapena aluminiyamu, wozungulira wozungulira, wozungulira wozungulira wozungulira.
Kutchinjiriza:XLPE kapena TR-XLPE kapena EPR.
Zoteteza zitsulo:Chitetezo cha waya wa mkuwa, chitetezo cha tepi ya mkuwa.
Chigoba:Chidebe cha aloyi cha lead, chidebe cha aluminiyamu chopangidwa ndi corrugated, chidebe cha mkuwa chopangidwa ndi corrugated.
Zida:Zida zotetezera waya za aluminiyamu (AWA), zida zotetezera waya zachitsulo (SWA), zida zotetezera waya zachitsulo chosapanga dzimbiri (SSWA).
Kuchuluka kwa Kutentha:
Kutentha kochepa kokhazikitsa: 0°C
Kutentha kwakukulu kogwira ntchito: +90°C
Kutentha kochepa kwambiri kogwira ntchito: -25°C
