Ikhebuli yamandla kagesi ephakathi kwe-MV Engafakwanga i-ASTM engu-15kV-XLPE
I-15kV CU 133% TRXLPE Full Neutral LLDPE Primary isetshenziselwa ukusabalalisa okuyisisekelo ngaphansi komhlaba kumasistimu emisele afanele ukusetshenziswa ezindaweni ezimanzi noma ezomile, ukungcwaba okuqondile, ipayipi elingaphansi komhlaba, nalapho kuchayeke elangeni.Izosetshenziswa ku-15,000 volts noma ngaphansi futhi emazingeni okushisa e-conductor angeqi ku-90°C ukuze usebenze okuvamile.

I-ASTM Standard 25kV-XLPE Ikhebula Lamandla Amandla Kagesi Ephakathi Le-MV
Izintambo ezingu-25KV zifanele ukusetshenziswa ezindaweni ezimanzi nezomile, amapayipi, imisele, imisele, amathreyi, ukungcwatshwa okuqondile lapho efakwe i-grounding conductor eduze ehambisana nesigaba se-NEC 311.36 kanye no-250.4 (A) (5), nalapho ugesi uphezulu kakhulu. izakhiwo ziyafiswa.Lezi zintambo ziyakwazi ukusebenza ngokuqhubekayo ezingeni lokushisa likakhondatha elingekho ngaphezu kuka-105°C ekusebenzeni okujwayelekile, u-140°C ekulayishweni okuphuthumayo, kanye no-250°C ezimeni zesekethe elifushane.Ikalwe ku-35°C ngokugoba okubandayo.I-ST1 (intuthu ephansi) Ilinganiselwe ngosayizi 1/0 nangaphezulu.Ijakhethi ye-PVC yenziwe ngobuchwepheshe be-SIM futhi ine-coefficient of friction COF engu-0.2.Ikhebula lingafakwa ku-conduit ngaphandle kosizo lokuthambisa.Ilinganiselwe ngo-1000 lbs./FT ukucindezela okukhulu kwe-sidewall.

I-ASTM Standard 35kV-XLPE Ikhebula Lamandla Amandla Kagesi Ephakathi Le-MV
I-35kV CU 133% TRXLPE Full Neutral LLDPE Primary isetshenziselwa ukusabalalisa okuyisisekelo ngaphansi komhlaba kumasistimu emisele afanele ukusetshenziswa ezindaweni ezimanzi noma ezomile, ukungcwaba okuqondile, ipayipi elingaphansi komhlaba, nalapho kuchayeke elangeni.Izosetshenziswa ku-35,000 volts noma ngaphansi futhi emazingeni okushisa e-conductor angeqi ku-90 ° C ekusebenzeni okujwayelekile.
