Application
PROXAR-IVN DC surge arresters in silicone housing are designed to protect lines, substations, and electrical equipment in the 1 kV to 4.7 kV range. The highly non-linear characteristics of the varistors used in their construction make them an effective replacement for traditional horn-type surge arresters, increasing supply reliability. They offer very high energy absorption capability and provide effective protection for traction equipment against repeated lightning strikes, induced surges, and transient overvoltages.

PROXAR-IVN DC arresters are suitable for both indoor and outdoor use in moderate and tropical climates at altitudes up to 1000 m above sea level. Their compact design allows installation in switchgear with a minimum pole spacing of 150 mm. They can also be equipped with a three-arm mounting base for seamless replacement of older-type lightning arresters (e.g. GZM, GXS, or POLIM H ND).
Equipment of any size and purpose can be supplied on request.
