ZnO Porcelain Housed Heavy Duty ZPR1

CG Porcelain/Polymer Housed distribution surge arresters are used in distribution systems to protect transformers and other medium voltage power equipment from lightning and switching surge generated over voltages. They exhibit excellent protective characteristics, temporary over voltage capability and switching surge energy withstand.


Gapless internal construction combined with a porcelain/polymer housing results in a design which is simple, reliable and economical to meet the most demanding service conditions. The design is based on field-proven metal oxide disks known for maintaining stable characteristics. In order to assure the highest level of quality, these arresters are designed and manufactured in accordance with the latest versions of IEC: 60099-4, IS-3070 and ANSI / IEEE C62.
