Polymer Housed Surge Arresters Aikọja Ẹjọ́ Pọpọ̀laimẹ́rì

Overview
A cikin kungiyar da ake amfani da su a kan lalacewar jirgin saman kamar 22.86 kV zuwa 500 kV (24 kV max zuwa 550 kV max), an samu SVN, PH3 da PH4 na yankin masana. Su ke bayyana zama zai gaba a nan mafi karfi a kan wani abubuwan da ake amfani da su a matsayin porcelain housed arresters (MVN family), baki daya ba a yi nasara a kan muhimmanci ko kudin alamun muhimmanci, idan ba a bukata karfi mai girma ta porcelain ba kuma idan kyau ya fi kyau a taka wani abu mai kyau. Kuma SVN, PH3 da PH4 families (zuwa 230kV MCOV) suna ci gaban IEE-Business Standard 693-2018 don High Seismic Performance.

Construction
    "Tube"design, using fiberglass reinforced epoxy tube overmolded with silicone rubber weathershed housing
    Single column of MOV discs and aluminum spacers (as required) centrally located within housing
    Disc column held under high spring compression between ductile iron end fittings affixed to housing
    Directional pressure relief system built integrated into end fittings

At-a-Glance
    High leakage distance designs (standard designs at least 28% more leakage distance than IEEE C62.11 minimum); higher leakage distance designs available for high pollution areas
    Up to 47% lighter than comparable porcelain arresters
    Resilient polymer housing resistant to mechanical damage
    Tested to 63kA rated short circuit current; can handle reclosures with no concern for housing fragmentation
