Station Class Polymer / Porcelain Arrester
Station class metal-oxide surge arresters in polymer or porcelain housings, protecting substation and transmission equipment through 612 kV.
Our AS Series is a station class metal-oxide surge arrester family designed to protect major substation and transmission equipment through 612 kV.
Overview
Applied by transmission and generation utilities to protect substation transformers, switchgear, capacitor banks, and cable terminations from lightning-induced and switching-induced overvoltages. The AS Series spans distribution through EHV service, with polymer and porcelain housing options across kV ratings up to 612 kV Ur, suited to demanding station and transmission duty.
Construction uses gapless metal-oxide varistor blocks with silicone-rubber (polymer) or glazed-porcelain housings. Polymer housings offer hydrophobic surfaces, non-fragmenting pressure-relief performance, and lighter weight for gantry-mounted installations. Porcelain housings provide the highest mechanical strength for exposed transmission service and are available in creepage classes matched to heavy pollution environments. Standard mounting includes NEMA 4-hole and single-eyebolt configurations; the EHV 588/612 kV units include gantry-mount hardware. Designs conform to ANSI/IEEE C62.11 and IEC 60099-4 with 100% routine testing per unit.
Typical deployments include substation transformer terminals, capacitor bank protection, shunt reactor terminals, cable-transition sea-cable applications, and 500/765 kV transmission line surge protection.
