Products – Porcelain Housed Surge Arresters – VL

VL, IEEE Station Class, IEC Class SM Overview – VL arresters are the most economical porcelain housed surge arrester to use on systems up to 69 kV (72.5 kV max). They are particularly attractive for medium duty applications, where their compact profile and strength are of importance. This feature can be well suited for cabinets, electrical enclosures or on mobile substations.

Construction: • Porcelain housing for maximized mechanical strength • Single column of MOV discs and aluminum spacers (as required) centrally located within housing • Disc column held under high spring compression between ductile iron end fittings affixed to housing • Directional pressure relief system built integrated into end fittings • Various hardware and end fittings to meet application requirements At-a-Glance: • Operate at altitudes up to 12,000 feet (3,600 meters) • Designed to withstand wind speeds in excess of 120 mph • Install straight from the package – no field assembly required • Dual qualified to IEEE and IEC standards
