Romela ImeileLikhoele tsa motlakase tse mahareng tsa motlakase tse nang le insulation ea XLPE ea 6.35-11kV li loketse marangrang a kabo kapa a phetiso ea bobeli, hangata li sebetsa e le phepelo ea motlakase ea mantlha bakeng sa marangrang a khoebo, indasteri le litoropo. Li sebetsa lits'ebetsong tse nang le maqhubu a phahameng a phoso a lekantsoeng ho fihla ho 10kA/motsotsoana o le mong. Meaho ea maqhubu a phoso a lekantsoeng a phahameng e fumaneha ha ho kopuoa. E loketse lits'ebetso tse sa fetoheng mobung, ka tlung/kantle, liphaepheng tsa cable, tse qoelitsoeng ka metsing, le moo likhoele li sa beoeng ke khatello e kholo ea mechini kapa khatello ea ho hula. Ka lebaka la ntlha ea eona e tlase haholo ea tahlehelo ea dielectric, e lulang e tsitsitse nakong eohle ea ts'ebeletso ea eona, le thepa e phahameng ea ho thibela mocheso ea thepa ea XLPE, thapo ena e bontša ts'epo e phahameng ea ts'ebetso. Thebe ea conductor le insulation ea thepa ea semiconductor li hokahantsoe ka mokhoa o sireletsehileng ka bolelele (extrusion ea single-pass). E loketse liteishene tse nyane, liteishene tsa motlakase le limela tsa indasteri.
Ho kenya thapo ya HV Cable XLPE ho na le melemo e latelang:
1.Tshebetso ea Khanyetso ea Mocheso:
XLPE e nang le sebopeho se nang le mahlakore a mararo se nang le mahlakore a mararo e na le ts'ebetso e ntle haholo ea ho hanyetsa mocheso. E ke ke ea bola le ho etsa carbonize ka tlase ho 300℃, mocheso oa ts'ebetso oa nako e telele o ka fihla ho 90℃, 'me bophelo ba mocheso bo ka fihla ho lilemo tse 40.
2.Tshebetso ea ho kenya lintho ka har'a insulation:
XLPE e boloka litšobotsi tse ntle tsa pele tsa ho thibela ho ruruha tsa PE, 'me khanyetso ea ho thibela ho ruruha e eketseha le ho feta.
Boleng ba eona ba tangent ea tahlehelo ea dielectric angle bo bonyenyane haholo, 'me ha bo angoe haholo ke mocheso.
3. Thepa ea Mekaniki:
Ka lebaka la ho thehwa ha ditlamo tse ntjha tsa dikhemikhale pakeng tsa dimolekhule tse kgolo, ho thatafala, ho satalla, ho hanyetsa ho kgohlahala le ho hanyetsa tshusumetso ya XLPE di ntlafaditswe, ka hona ho lokisa mefokolo ya PE e kotsing ya kgatello ya tikoloho le ho petsoha.
4. Litšobotsi tsa Khanyetso ea Lik'hemik'hale:
XLPE e na le khanyetso e matla ea asiti le alkali le khanyetso ea oli, 'me lihlahisoa tsa eona tsa ho tuka ke metsi le carbon dioxide, tse seng kotsi hakaalo tikolohong 'me li fihlela litlhoko tsa polokeho ea mollo ea sejoale-joale.
Kaho:
Kaho:Triplex ea mantlha e le 'ngoe, ea mantlha e meraro, ea mantlha e 3×1.
Motsamaisi:Koporo kapa aluminium, e chitja e thibiloeng, e chitja e nyane e thibiloeng.
Ho kenya mocheso:XLPE kapa TR-XLPE kapa EPR.
Tšireletso ea tšepe:Sethibelo sa terata ea koporo, sethibelo sa theipi ea koporo.
Selateng:Sekoahelo sa motsoako oa loto, sekoahelo sa aluminium se kobehileng, sekoahelo sa koporo se kobehileng.
Lihlomo:Lihlomo tsa terata tsa aluminium (AWA), lihlomo tsa terata tsa tšepe (SWA), lihlomo tsa terata tsa tšepe e sa ruseng (SSWA).
Maemo a Mocheso:
Mocheso o tlase oa ho kenya: 0°C
Mocheso o phahameng ka ho fetisisa oa ts'ebetso: +90°C
Mocheso o fokolang o sebetsang: -25°C
