Kodi zingwe zomwe zimagwiritsidwa ntchito pazombo zapamadzi ndi nsanja zakunja ndi ziti?Zotsatirazi ndizofotokozera za mitundu ya zingwe zamagetsi zomwe zimagwiritsidwa ntchito pa zombo ndi nsanja za m'mphepete mwa nyanja.
1. Cholinga:
Mtundu uwu wa chingwe ndi woyenera kufalitsa mphamvu mu machitidwe a mphamvu ndi AC oveteredwa voteji 0.6/1KV ndi pansi pa zombo zosiyanasiyana mitsinje ndi nyanja, mafuta m'mphepete mwa nyanja ndi nyumba zina madzi.
2. Mulingo wolozera:
IEC60092-353 1KV ~ 3KV ndi pansi extruded olimba kutchinjiriza zingwe mphamvu m'madzi
3. Gwiritsani ntchito mawonekedwe:
Ntchito kutentha: 90 ℃, 125 ℃, etc.
Mphamvu yamagetsi U0/U: 0.6/1KV
Malo opindika ochepa: osachepera 6 kuwirikiza kwa chingwe chakunja
Moyo wautumiki wa chingwe suchepera zaka 25.
4. Zizindikiro zamachitidwe:
Kukaniza kwa DC kwa conductor pa 20 ° C kumakumana ndi muyezo wa IEC60228 (GB3956).
Kukaniza kwa chingwe pa 20 ° C sikuchepera 5000MΩ·km (kwapamwamba kwambiri kuposa index ya magwiridwe antchito ya kukana kukana kofunikira ndi muyezo wa IEC60092-353).
Ntchito yobwezeretsanso moto imakwaniritsa zofunikira za IEC60332-3-22 Class A retardant (moto kwa mphindi 40, ndipo kutalika kwa chingwe cha carbonization sikudutsa 2.5m).
Kwa zingwe zosagwira moto, ntchito yawo yolimbana ndi moto imakumana ndi IEC60331 (mphindi 90 (moto) + mphindi 15 (pambuyo pochotsa moto), kutentha kwa lawi 750 ℃ (0 ~ +50 ℃) chingwe chamagetsi ndi chachilendo, palibe magetsi).
Chizindikiro chochepa cha halogen-free index cha chingwe chimakwaniritsa zofunikira za IEC60754.2, kutulutsidwa kwa mpweya wa halogen acid sikuposa 5mg / g, kuzindikira kwapadera kwa pH yake sikuchepera 4.3, ndipo ma conductivity si. kuposa 10μs/mm.
Utsi wochepa wa chingwe: Kuchuluka kwa utsi (kutumiza kuwala) kwa chingwe sikuchepera 60%.Kukwaniritsa zofunikira za IEC61034.
5. Kapangidwe ka chingwe
Kondakitalayo amapangidwa ndi mkuwa wapamwamba kwambiri wopangidwa ndi zitini.Mtundu uwu wa kondakitala uli ndi anti-corrosion effect yabwino kwambiri.Kapangidwe ka kondakitala kagawika m'ma conductor olimba, ma conductor otsekeka ndi ma conductor ofewa.
Insulation imagwiritsa ntchito kusungunula kwa extruded.Njira yotulutsirayi imatha kuchepetsa mpweya pakati pa kondakitala ndi kutchinjiriza kuteteza kulowa kwa zonyansa monga mpweya wamadzi.
Khodi yamtundu nthawi zambiri imasiyanitsidwa ndi mtundu.Mitundu imatha kusankhidwa ndikusinthidwa malinga ndi zosowa za malo kuti ikhale yosavuta.
M'kati mwake sheath/liner (Jaketi) ndi chinthu chopanda utsi chochepa cha halogen chokhala ndi moto woyaka kwambiri.Zinthuzo ndi zaulere za halogen.
Zida zankhondo (Armor) ndi mtundu woluka.Zida zamtunduwu zimakhala ndi kusinthasintha kwabwinoko ndipo ndizosavuta kuyala chingwe.Zida zankhondo zolukidwa zimaphatikizapo mawaya amkuwa omata ndi waya wazitsulo, zonse zili ndi mphamvu yoletsa dzimbiri.
Zakunja m'chimake (m'chimake) zakuthupi ndi otsika utsi wopanda halogen.Izi sizimatulutsa mpweya wapoizoni zikayaka ndipo zimatulutsa utsi wochepa.Amagwiritsidwa ntchito kwambiri m'malo odzaza anthu.
Chidziwitso cha chingwe chikhoza kusindikizidwa malinga ndi zosowa zenizeni.
6. Mtundu wa chingwe:
1. XLPE yotsekera chingwe chopanda utsi chochepa cha halogen wopanda utsi wakunja:
CJEW/SC, CJEW/NC, CJEW95(85)/SC, CJEW95(85)/NC,
2. EPR yotsekera chingwe chopanda utsi chochepa cha halogen wopanda utsi wakunja:
CEEW/SC, CEEW/NC, CEEW95(85)/SC, CEEW95(85)/NC,
3. Kufotokozera zachitsanzo:
C- amatanthauza chingwe chamagetsi apanyanja
Kusungunula kwa J-XLPE
E-EPR (Ethylene Propylene Rubber Insulation)
EW-low utsi wa halogen wopanda polyolefin sheath
95- Zitsulo zachitsulo zolukidwa ndi zitsulo zachitsulo ndi LSZH m'chimake chakunja (kachulukidwe kazitsulo zosachepera 84%)
85 - Zida zomata za waya wamkuwa ndi m'chimake wakunja wa LSZH (kachulukidwe kake osachepera 84%)
Kugwira ntchito koletsa moto kwa SC-chingwe kumakumana ndi IEC60332-3-22 Class A retardant, ndipo zomwe zili ndi halogen ndizochepera 5mg/g.
NC - Kukana kwa moto kwa chingwe kumakumana ndi IEC60331, ndipo zomwe zili halogen ndizochepera 5mg/g
