CG Porcelain housed (ZYPD) distribution surge arresters are used on 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 housing results in a design which is simple, reliable and economical to meet the most demanding service conditions. CG arrester 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.
