TD231 Datasheet PDF

SUBJECT: Technical Specifications for 5 kA, Normal-Duty Distribution 4.5 kV and 5 kV VariSTAR® MOV Disks APPLICATION Technical Data TD-231 The VariSTAR MOV (Metal Oxide Varistor) disks described in this Technical Data sheet are for use as active elements in IEC 5 kA and ANSI Normal-Duty Distribution Class Surge Arresters, when applied in an appropriately designed arrester. Polymer Housed Arrester Designs: Use the glass collared AV5NG series VariSTAR disks, when applying disks to a polymer housed arrester, where the dielectric strength of the material in direct contact with the disks exceeds the dielectric strength of air. Porcelain Housed Arrester Designs: Option 1. Use the glass collared AV5NG series VariSTAR disk together with an Epoxy Film Tape, as described in technical data sheet TD-241, when applying disks in a porcelain housed arrester, where the material in direct contact with the VariSTAR disks is equal to the dielectric strength of air. Option 2. Use the epoxy collared AV5NE...
