Powerful ventilators, pumps, mills, grinders are actuated by a wound-rotor induction motor.
Starting current of a wound-rotor induction motor without a starting resistor may exceed itsrated current by factor of 7, which may impair the mains supply.
To provide smooth increase of starting current and the motor shaft torque, starting resistors are used. "PPTG", Ltd. develops and manufactures liquid and oil starting resistorsessential in severe applications, which are noted for low cost of service and high operational reliability.
The Penza Plant Telema Gino offers a wide range of resistors, optimal prices, unique terms of cooperation including an option of designing and making customized electrical equipment taking account of specific requirements.
