H Series Resistors

Our high voltage resistors are designed to function and survive for 20 years in the dirty, noisy, cramped quarters of a locomotive, under a transit car, or on the rooftop of an electric bus. They meet stringent requirements of vibration, dust, humidity, caustic wash solutions, metal and fiber dust coatings from mechanical brake linings and are designed to meet specific inductance and electrical creep-age and air gap requirements.
Our off-highway resistors provide the additional benefits:
- Designed as exact replacements for most electric drive applications
- Incorporates the latest design technologies in insulating materials and air flow/heat transfer advances
- High strength, state-of-the-art insulation systems
- Develops lower back pressures on fans to improve air flow/heat transfer
- Compensates for poor air flows at edge of grid from hatch design
- Custom designs available
