ASTM Standard 25kV-XLPE Insulated MV Middle Voltage Power Cable

ASTM Standard 25kV-XLPE Insulated MV Middle Voltage Power Cable

Fa'amatalaga:

    25KV uaea e fetaui lelei mo le faʻaogaina i nofoaga susu ma matutu, alavai, alavai, alavai, fata, tanu saʻo pe a faʻapipiʻiina i se faʻamalo faʻavae latalata e ogatasi ma le NEC vaega 311.36 ma le 250.4 (A) (5), ma pe a sili atu le eletise. e mana'omia meatotino.O nei uaea e mafai ona faʻaauau pea le faʻaogaina i le vevela o le taʻavale e le sili atu i le 105 ° C mo galuega masani, 140 ° C mo faʻalavelave faʻafuaseʻi, ma le 250 ° C mo tulaga puʻupuʻu.Fa'atatau ile -35°C mo le pi'o malulu.ST1 (maualalo le asu) Fa'atatau mo lapopoa 1/0 ma lapopoa.O le peleue PVC e faia i tekinolosi SIM ma o loʻo i ai le coefficient o feteʻenaʻiga COF o le 0.2.E mafai ona fa'apipi'i le uaea i totonu o le alavai e aunoa ma se fesoasoani o le lubrication.Fa'atauaina mo le 1000 lbs./FT pito maualuga pito puipui puipui.

Talosaga:

25kV CU 133% TRXLPE Neutral LLDPE Primarysed mo le tufatufaina muamua i lalo o le eleele i alavai e talafeagai mo le faaaogaina i nofoaga susu pe matutu, tanu tuusao, alavai lalo o le eleele, ma nofoaga e susulu i le la.E fa'aoga ile 25,000 volts pe la'ititi ma ile fa'avevela ole vevela e le sili atu ile 90°C mo galuega masani.

Fausia:

Ta'ita'i: Vasega A po'o le B Fa'amauCconcentric pa'ia alumini alumini, Alumini po'okomea komea.O ta'avale ua pa'ia ua poloka vai ma fa'atumu fa'atumu.
Talita Fa'atonu: Talita semiconducting thermosetting fa'apipi'iina lea e sa'oloto e aveese mai le ta'avale ma fa'apipi'i i le fa'aluma.
Insulation: Extruded, le faatumuinaPolyethylene Feso'ota'i o La'au (TR-XLPE)e pei ona faʻamatalaina i le ANSI/ICEA S-94-649 - 133% tulaga faʻapipiʻi.
Talita Insulation: Talita semiconducting thermosetting extruded faatasi ai ma le pipii pulea i le insulation maua ai le paleni manaomia i le va o le sa'o eletise ma le faigofie o le aveeseina.
Talita Metallic:O uaea apamemea fa'ameamea ma'a'a fa'aoga fa'alelei ma tu'u tutusa le va.
Poloka Suavai: O mea e pupuni ai le vai e fa'aoga i luga o le talipupuni fa'amama ma fa'ata'amilo i uaea fa'aituau e fa'asa'o ai le so'o o le vai.E tatau ona fa'ata'ita'i le tu'ina o le vai fa'aumi e tusa ai ma le lomiga lata mai o le ICEA T-34-664 se'i vagana ai le mana'oga aupito maualalo ole 15 psig mo le 1 le itula.
Peleti: Laiseau Low Density Polyethylene (LLDPE) peleue, uliuli ma lanu mumu
