| Porcelain Housed Distribution Class Surge Arresters
CPS continues to offer a full line of porcelain housed distribution class arresters. Porcelain housings have been used for
arresters for many years with a tremendously reliable service history. Porcelain will not deteriorate, decompose, or change
characteristics over time no matter how severe the environment. Arresters can be ordered in standard or high creepage (leakage)
housings for contaminated applications. A wide range of mounting brackets and accessories are also available to customize
the arrester as needed.
