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

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

Zofotokozera:

    Zingwe za 25KV ndizoyenera kugwiritsidwa ntchito m'malo onyowa ndi owuma, ma ducts, mathire, mathireyi, maliro achindunji akayikidwa ndi kondakitala wapansi pafupi ndi gawo la NEC 311.36 ndi 250.4 (A) (5), komanso komwe kuli magetsi apamwamba kwambiri katundu amafunidwa.Zingwezi zimatha kugwira ntchito mosalekeza pa kutentha kwa kondakitala osapitilira 105 ° C kuti zigwire bwino ntchito, 140 ° C pakudzaza mwadzidzidzi, ndi 250 ° C pakanthawi kochepa.Idayezedwa pa -35 ° C chifukwa chopindika chozizira.ST1 (utsi wochepa) Wovotera kukula kwake 1/0 ndi kukulirapo.Jekete la PVC limapangidwa ndiukadaulo wa SIM ndipo lili ndi coefficient of friction COF ya 0.2.Chingwe chikhoza kuikidwa mu ngalande popanda kugwiritsa ntchito mafuta.Idavoteredwa ndi 1000 lbs./FT kuthamanga kwambiri kwapambali.

Ntchito :

25kV CU 133% TRXLPE Yonse Yosalowerera Ndale LLDPE Pulayimalesed kuti igawidwe mobisa m'makina oyenera kugwiritsidwa ntchito m'malo onyowa kapena owuma, maliro achindunji, ngalande yapansi panthaka, komanso pomwe pamakhala kuwala kwadzuwa.Iyenera kugwiritsidwa ntchito pa 25,000 volts kapena kuchepera komanso kutentha kwa conductor kusadutsa 90 ° C kuti igwire bwino ntchito.

Zomanga :

Kondakitala: Kalasi A kapena B WopanikizidwaCconcentric stranded aluminium alloy, Aluminium kapenakondakitala wamkuwa.Makondakitala otsekeka amakhala otchingidwa ndi madzi ndi ma conductor filling compound.
Conductor Shield: Chishango chowonjezera cha thermosetting semiconducting chomwe chimakhala chaulere kuchokera pa kondakitala ndikumangirira ku zotsekera.
Kuthirira: Kutuluka, kusadzazaTree-Retardant Cross-linked Polyethylene (TR-XLPE)monga tafotokozera mu ANSI/ICEA S-94-649 - 133% mulingo wa kutchinjiriza.
Insulation Shield: Chishango chowonjezera cha thermosetting semiconducting chomata mowongolera ku zotsekera zomwe zimapereka malire ofunikira pakati pa kukhulupirika kwamagetsi ndi kuvula kosavuta.
Metallic Shield:Mawaya a mkuwa olimba opangidwa ndi helically ogwiritsidwa ntchito mofanana.
Madzi otchinga: Otsekereza madzi amapaka chishango chotchinga ndi kuzungulira mawaya osalowererapo kuti asalowe madzi atalitali.Kulowa kwamadzi kwakutali kudzayesedwa molingana ndi kusindikiza kwaposachedwa kwa ICEA T-34-664 kupatula kuti chofunikira ndi 15 psig kwa ola limodzi.
Jacket: Jacket ya Linear Low Density Polyethylene (LLDPE), yakuda yokhala ndi mikwingwirima yofiira

Zofotokozera:

Mafotokozedwe Okhazikika a ASTM B3 a Waya Wofewa kapena Wowonjezera
ASTM B8 Concentric-Lay-Stranded Copper Conductors
ICEA S-94-649 Muyezo wa Zingwe Zosalowerera Ndale Zovoteledwa 5 - 46kV
Kufotokozera kwa AEIC CS-8 kwa zingwe zamagetsi zotetezedwa ndi dielectric zovotera 5 mpaka 46KV
