Overview
A cikin ɗaya, Standard SVN, PH3 da PH4 station class arresters suna da amfani a harsuna daga 22.86 kV zuwa 500 kV (24 kV max zuwa 550 kV max). Sun bayarwa masu tashin zafi don take da ƙarin abubuwa ba da wani al'adu na porcelan housed arresters (MVN family), baki daya da yawa a tashin inganci ko a tashin kayayyakin ƙwarewa, a lokutan da ya kamata ƙarin ƙarfi na porcelan ba da shi ba, kuma a lokutan da zai iya haɗa da ƙarin karfi. A gaba, SVN, PH3 da PH4 families (zuwa 230kV MCOV) suna da amfani don High Seismic Performance ta hanyar IEEE Standard 693-2018.

SVNH arresters suna da amfani a harsuna daga 161 zuwa 500 kV. Waɗannan arresters sun bayarwa masu tashin zafi don take da ƙarin ƙarfi na SVN arresters, baki daya da yawa a tashin inganci ko a tashin kayayyakin ƙwarewa.

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
