Umgangatho we-ASTM we-25kV-XLPE ofakwe i-MV Middle Voltage Power Cable

Umgangatho we-ASTM we-25kV-XLPE ofakwe i-MV Middle Voltage Power Cable

Iinkcukacha:

    Iintambo ze-25KV zilungele ukusetyenziswa kwiindawo ezimanzi kunye nezomileyo, i-conduits, i-ducts, i-troughs, i-trays, ukungcwatywa ngokuthe ngqo xa ifakwe kunye ne-conductor yokumisa ngokusondeleyo ehambelana necandelo le-NEC 311.36 kunye ne-250.4 (A) (5), kwaye apho umbane ophezulu wombane iipropati ziyafunwa.Ezi ntambo ziyakwazi ukusebenza ngokuqhubekayo kwiqondo lokushisa elingekho ngaphezu kwe-105 ° C ekusebenzeni okuqhelekileyo, i-140 ° C yokugqithisa ngokukhawuleza, kunye ne-250 ° C kwiimeko zesekethe ezimfutshane.Ilinganiswe kwi -35 ° C ngenxa yokugoba okubandayo.I-ST1 (umsi ophantsi) Ilinganiswe ngobungakanani be-1/0 nangaphezulu.Ijacket ye-PVC yenziwe ngeteknoloji ye-SIM kwaye ine-coefficient ye-friction COF ye-0.2.Ikhebula inokufakwa kwi-conduit ngaphandle koncedo lokuthambisa.Ilinganiswe kwi-1000 lbs./FT ubuninzi boxinzelelo lwe-sidewall.

Isicelo :

25kV CU 133% TRXLPE NgokungaPhangaleleyo ngokuNgaphakathi kweLLDPE Primaryisetyenziselwe usasazo olusisiseko oluphantsi komhlaba kwiinkqubo zemibhobho elungele ukusetyenziswa kwiindawo ezimanzi okanye ezomileyo, ukungcwatywa ngokuthe ngqo, umjelo ongaphantsi komhlaba, nalapho udibane nelanga.Iza kusetyenziswa kwi-25,000 volts okanye ngaphantsi kwaye kwi-conductor iqondo lokushisa lingadluli kwi-90 ° C ekusebenzeni okuqhelekileyo.

Ulwakhiwo :

IKondi: Udidi A okanye B lucinezelweIngxubevange ye-aluminiyam ene-Cconcentric, Aluminiyam okanyeumqhubi wobhedu.Ii-conductors ezidibeneyo zivaliwe ngamanzi kunye nekhompawundi yokuzalisa i-conductor.
IKhaka le-Conductor: Ikhaka elongezelelweyo le-thermosetting semiconducting ekhululekile ukuhluthwa kwi-conductor kwaye ibotshelelwe kwisigqubuthelo.
I-Insulation: Ikhutshiwe, ayizaliswangaI-Polyethylene eNqamkileyo eDityaniswe ngumthi (TR-XLPE)njengoko kuchazwe kwi-ANSI / ICEA S-94-649 - i-133% yezinga lokugquma.
I-Insulation Shield: Ikhaka elongezelelweyo le-thermosetting semiconducting kunye nokubambelela okulawulwayo kwi-insulation enikezela ibhalansi efunekayo phakathi kwemfezeko yombane kunye nokukhululeka kokuqhawula.
Metallic Shield:Iingcingo zobhedu eziqinileyo ezifakwe kwi-helically kwaye zahlulwe ngokulinganayo.
Ibhloko yaManzi: Iiarhente ezithintela amanzi zifakwa phezu kwesikhuselo sokugquma kunye nokujikeleze iingcingo ezingathathi hlangothi ukuxhathisa ukungenwa kwamanzi okude.Ukungena kwamanzi okude kuya kuvavanywa ngokuhambelana noshicilelo lwamva nje lwe-ICEA T-34-664 ngaphandle kokuba ubuncinci bemfuno yi-15 psig ngeyure eli-1.
Ibhatyi: Ibhatyi yeLinear Low Density (LLDPE), emnyama enemigca ebomvu ekhutshiweyo
