Litaelo tsa Sehlahisoa sa Tšebeliso

A) nakong ea ts'ebetso e tloaelehileng ea thapo, mocheso o phahameng oa conductor e tla ba 70 ℃ bakeng sa insulation ea PVC le 90 ℃ bakeng sa insulation ea XLPE.
B) Mocheso o phahameng oa conductor nakong ea potoloho e khuts'oane (nako e telele e sa feteng metsotsoana e 5):
PVC insulation -- 160 ℃ bakeng sa conductor cross section ≤300mm2, 140 ℃ bakeng sa conductor cross section> 300mm2;Insulation ea PVC e pharalletseng ho 250 ℃.
C) Ha o beha likhoele, mocheso o tikolohong ha oa lokela ho ba ka tlase ho 0 ℃, mme sebaka se tlase se lumelletsoeng sa ho kobeha ke ka tsela e latelang:

Likarolo tsa sebopeho sa sehlahisoa

1. E na le khanyetso e ntle ea mocheso o phahameng: XLPE e sebelisa mekhoa ea lik'hemik'hale kapa ea 'mele ho fetola sebopeho sa limolek'hule tsa polyethylene hore e be sebopeho sa marang-rang a mararo.Sebopeho sa marang-rang se nang le likarolo tse tharo se na le mocheso o motle oa ho hanyetsa 'me se ka sebelisoa mosebetsing oa Nako e telele mocheso o phahameng oa likhato tse 90 tsa Celsius, nako ea bophelo e ka ba lilemo tse 40.
2. E na le ts'ebetso e ntle ea ts'ebetso: ts'ebetso ea polyethylene ha e boloke feela ts'ebetso ea ts'ebetso ea polyethylene e kopantsoeng le sefapano, empa e boetse e na le ntlafatso e 'ngoe ea ho hanyetsa mocheso.
3. Lintho tse phahameng tsa mechine: ho thatafala, ho satalla, ho hanyetsa ho apara le ho hanyetsa tšusumetso ho ntlafalitsoe
4. Ho hanyetsa lik'hemik'hale: XLPE ka boeona e na le acid e matla le khanyetso ea alkali le ho hanyetsa oli
5. Tšireletso ea tikoloho: Kaha lihlahisoa tsa mollo oa polyethylene tse amanang le sefapano ke metsi le carbon dioxide, tšilafalo ea tikoloho e tlaase, 'me e finyella litlhoko tsa tšireletso ea mollo.
6. Mocheso o phahameng oa mocheso oa mochine oa motlakase ke 90 ° C, 'me mocheso o phahameng oa mochine oa motlakase nakong ea potoloho e khutšoanyane (nako e telele ka ho fetisisa ha e fete 5S) ha e fete 250 ° C.
