Product Description



Resistance boxes are used to add resistance in to an electric motor circuit for modifying the performance characteristic of slipring induction motors of EOT cranes, rubber mills, steel rolling mills, cement mills, power plants, conveyors, coke oven, blowers etc.

 

For speed control and developing staring torque with low starting currents, they are also used as Dynamic breaking resistor for V.V.V.F.A.C. Drives electric loading of ac alternators, de generators and dynamo meters. Resistors are designed to meet requirements of both A.C. and D.C. applications.

  • The basic types of resistors are: Punched Steel Resistors. (Stainless steel / Fecral ).
  • The system of cooling the resistors is of two types. One is Air cooled typeand the other is Oil cooled type.
