RI80 is able to absorb large amounts of energy at high voltage while remaining non-inductive. Ideal for: Capacitor crowbar circuits, Impulse voltage generators, Energy research, Pulse modulators, Radar Pulse-forming networks, High voltage snubber circuits, Arc furnace damping, X-ray/imaging equipment, and EMI/lightning supression. This general line of tubular is available in a wide variety of sizes and terminations. They retain the non-inductive and heavy load characteristics. RI80 can handle up to 35 KV.
