Rugged Construction and Superior Insulation

Kato Engineering traction alternators are the premier choice for mine-haul trucks. These traction alternators provide the power for today’s electric drive systems.  Kato traction alternators’ compact design helps increase vehicle payload along with profitability.  Rugged construction and superior insulation ensure they can handle bumpy, grimy conditions as well as thermal cycling caused by the constant acceleration and deceleration of mine-haul truck duty.
