Ohereza ImeliInsinga z'amashanyarazi za 12.7-22kV-XLPE zishyushye zifite amashanyarazi aciriritse zikunze gukoreshwa mu miyoboro ikwirakwiza amashanyarazi n'insinga z'amashanyarazi zifasha mu bidukikije bitandukanye. Utu dukoresho tw'uburinzi twemerera gushyingura mu buryo butaziguye kugira ngo hirindwe impanuka z'amashanyarazi no kwangirika. Ubwoko bwa AS/NZS 12.7-22kV-XLPE bugizwe n'insinga z'amashanyarazi za volteji ziciriritse zakozwe hakurikijwe AS/NZS 1429.1 yo muri Ositaraliya/Nouvelle-Zélande. Zikwiriye gushyirwa mu miyoboro y'amashanyarazi haba mu nzu no hanze, kandi zishobora gushyirwa mu miyoboro y'insinga, ku dusanduku tw'insinga, cyangwa zishyinguwe mu butaka. Zikwiriye sisitemu z'amashanyarazi menshi kugeza kuri 10kA/isegonda 1. Inyubako zifite ubushobozi bwo gukwirakwiza umuriro mwinshi ziraboneka iyo ubisabye.
Ubwubatsi:
Umuyobozi:Umuringa cyangwa aluminiyumu, ifite impande zifunganye, ifite impande nto.
Ubwishingizi bw'umuriro:XLPE cyangwa TR-XLPE cyangwa EPR.
Ubwirinzi bw'icyuma:Uburinzi bw'insinga z'umuringa (CWS), uburinzi bw'insinga z'umuringa (CTS).
Ikiziriko:Agakoresho ka aluminiyumu gakozwe muri korrugation (CAS), Agakoresho k'umuringa gakozwe muri korrugation (CCU), Agakoresho k'icyuma kitagira umugese gakozwe muri korrugation (CSS).
Intwaro:Insinga za aluminiyumu (AWA), Insinga z'icyuma (SWA), Insinga zitagira umugese (SSWA).
Kurinda inkeri:Agati ka nylon ka polyamide, kaseti y'umuringa ibiri (DBT), Cypermethrin.
Insinga zo gushyiramo:12D (PVC gusa) 15D (HDPE).
Mu gihe cyo gushyiraho:18D (PVC gusa) 25D (HDPE).
Ingano y'ubushyuhe:
Ubushyuhe buke bwo gushyiraho: 0°C
Ubushyuhe ntarengwa bwo gukora: +90°C
Ubushyuhe buke bwo gukora: -25°C
Insinga za Voltage yo Hagati zakozwe ku buryo bwihariye:
Kugira ngo imikorere irusheho kuba myiza kandi irambe, buri nsinga ya MV igomba guhindurwa hakurikijwe uko ishyirwamo ariko hari igihe insinga yabugenewe iba ikenewe. Impuguke zacu za MV zishobora gukorana nawe mu gushushanya igisubizo gihuye n'ibyo ukeneye. Akenshi, guhindura imiterere y'ibikoresho bigira ingaruka ku bunini bw'agace k'icyuma, gashobora guhindurwa kugira ngo hahindurwe ubushobozi bwa "short circuit" n'ibikenewe mu gucukura.
Muri buri kibazo, amakuru ya tekiniki atangwa kugira ngo hagaragazwe ko akwiriye kandi hakosorwe ibisabwa kugira ngo bikorwe. Ibisubizo byose byihariye bigomba gupimwa neza mu kigo cyacu cyo gupima insinga za MV.
