I-ASTM Standard 25kV-XLPE Ikhebula Lamandla Amandla Kagesi Ephakathi Le-MV

I-ASTM Standard 25kV-XLPE Ikhebula Lamandla Amandla Kagesi Ephakathi Le-MV

Imininingwane:

    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.

Isicelo :

25kV CU 133% TRXLPE Okugcwele Okumaphakathi kwe-LLDPE Primarysed ukuze kusatshalaliswe ngaphansi komhlaba kumasistimu emisele afanele ukusetshenziswa ezindaweni ezimanzi noma ezomile, ukungcwaba okuqondile, ipayipi elingaphansi komhlaba, nalapho kuchayeke elangeni.Izosetshenziswa ku-25,000 volts noma ngaphansi futhi emazingeni okushisa e-conductor angeqi ku-90 ° C ekusebenzeni okujwayelekile.

Ukwakha :

I-Conductor: Ikilasi A noma B LicindezelweIngxubevange ye-aluminium ene-concentric stranded, Aluminium nomaumqhubi wethusi.Ama-conductor ahlanganisiwe avinjwe amanzi ngenhlanganisela yokugcwalisa i-conductor.
I-Conductor Shield: Isivikelo esinwetshiwe se-thermosetting semiconducting esikhumula mahhala ku-conductor futhi esiboshelwe ku-insulation.
I-Insulation: Inwetshiwe, ayigcwalisiweI-Tree-Retardant Cross-linked Polyethylene (TR-XLPE)njengoba kuchazwe ku-ANSI/ICEA S-94-649 - 133% izinga lokwahlukanisa.
I-Insulation Shield: Isihlangu esinwetshiwe se-thermosetting semiconducting esinamathela okulawulwayo ku-insulation esinikeza ibhalansi edingekayo phakathi kobuqotho bukagesi kanye nokukhumula kalula.
Metallic Shield:Izintambo eziqinile zethusi ezifakwe i-helically futhi zihlukaniswe ngokulinganayo.
I-Water Block: Ama-agent avimbela amanzi asetshenziswa phezu kwesivikelo se-insulation futhi eduze kwezintambo ezingathathi hlangothi ukuze amelane nokungena kwamanzi ngobude.Ukungena kwamanzi okude kuzohlolwa ngokuhambisana nohlelo lwakamuva lwe-ICEA T-34-664 ngaphandle kokuthi imfuneko encane ingu-15 psig ihora elingu-1.
Ijakhethi: I-Linear Low Density Polyethylene (LLDPE) Jacket, elimnyama elinemigqa ebomvu ekhishwe

Imininingwane:

Ukucaciswa Okujwayelekile kwe-ASTM B3 Kocingo Lwethusi Oluthambile noma Olune-Annealed
I-ASTM B8 Concentric-Lay-Stranded Copper Conductors
I-ICEA S-94-649 Izinga lamakhebuli Amaphakathi Amaphakathi Alinganiselwe 5 - 46kV
Ukucaciswa kwe-AEIC CS-8 kwezintambo zamandla ezivikelwe ze-dielectric ezikhishwe zilinganiselwe ngo-5 kuya ku-46KV
