Impulse Resistors


These Impulse resistors are used with impulse generators of any design for wave shaping purpose. The non-inductive, Nichrome wire wound resistors are best suitable for Lightning, switching & current impulse waves shaping application. These resistors can be fixed in impulse generator to get required front and tail time of the waves. These resistors are suitable for indoor impulse generators and can be used as front (series), Tail (Parallel), output damping resistor with taps and Trigger resistors used in multiple chopping gaps. The flat and circular shape impulse resistors are available. We are designing and manufacturing various ratings of customized impulse resistors.

We also design and manufacturing DC Charging,Current limiting and Grounding resistors.
