AS/NZS heerka 6.35-11kV-XLPE dahaaran MV Korontada

Tilmaamaha:

    Qaybinta korantada ama fiilooyinka gudbinta hoose ee sida caadiga ah loo isticmaalo sahayda aasaasiga ah ee shabakadaha degaanka ee ganacsiga, warshadaha iyo magaalooyinka.Ku habboon nidaamyada heerka khaladka sare ee lagu qiimeeyay ilaa 10kA/1sec.Dhismayaasha hadda lagu qiimeeyay cilad sare ayaa diyaar ah haddii la codsado.u shaqeeyay codsiga taagan ee dhulka, gudaha iyo dibaddaba, bannaanka, kanaalka fiilada, biyaha, xaaladaha aan fiilooyinka aan la kulmin culeys farsamo oo culus iyo cadaadis adag.Sababta oo ah qodobka aadka u hooseeya ee luminta dielectric, kaas oo si joogto ah u sii jira cimrigiisa oo dhan, oo ay ugu wacan tahay hantida dahaarka ee aadka u wanaagsan ee walxaha XLPE, oo si qotodheer ugu qotoma shaashadda kirishbooyada iyo shaashadda dahaarka ee walxo semi-conductive ah (oo lagu soo saaray hal hab). fiilada ayaa leh isku halaynta hawleed sare.Loo isticmaalo xarumaha beddelka, warshadaha korontada iyo warshadaha warshadaha.

    Alaab-qeybiyaha fiilo dhexdhexaadka ah ee dhexdhexaadka ah ee caalamiga ah wuxuu bixiyaa noocyo kala duwan oo buuxa oo ah fiilooyinka korantada ee dhulka hoostiisa ee kaydkayaga iyo sidoo kale fiilooyinka korantada.

HV Cable Insulation XLPE waxay leedahay faa'iidooyinka soo socda:

1.Waxqabadka iska caabinta kulaylka:
XLPE oo leh qaab-dhismeed saddex-geesood ah oo dib loo furay ayaa leh waxqabadka iska caabinta kulaylka oo aad u wanaagsan.Ma dumin doonto oo kaarboonaysiisay ka hooseeya 300 ℃, heerkulka shaqada muddada-dheer wuxuu gaari karaa 90 ℃, nolosha kulaylkuna waxay gaari kartaa 40 sano.
2.Waxqabadka Insulation:
XLPE waxay xajisaa astaamihii asalka ahaa ee dahaarka wanaagsan ee PE, caabbinta dahaadhka ayaa sii kordhaysa.
Qiimaha tangent xagal luminteeda dielectric waa mid aad u yar, si weynna uma saameeyo heerkulka.
3.Guryaha Makaanikada:
Sababo la xiriira samaynta curaarta cusub ee kiimikaad ee u dhexeeya makromolecules, qallafsanaanta, qallafsanaanta, iska caabbinta abrasion, iyo iska caabbinta saamaynta XLPE ayaa la wanaajiyey, sidaas darteed samaynta cilladaha PE ee u nugul walaaca deegaanka iyo dillaaca.
4. Astaamaha iska caabinta Kiimikada:
XLPE waxay leedahay caabbinta aashitada iyo alkali xoog leh iyo caabbinta saliidda, iyo alaabteeda gubashadeedu waxay u badan yihiin biyaha iyo carbon dioxide, kuwaas oo aan waxyeello u lahayn deegaanka oo buuxiya shuruudaha badbaadada dabka ee casriga ah.
