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 dynamometers. 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 type and the other is Oil cooled type.

Powermech offers high-quality, high-precision, wire wound resistors, which are extremely stable over time and function over wide operating temperatures.
Quality resistors are essential in protecting electronic components from sudden current or voltage changes. Such unpredictable changes can be potentially hazardous to electronic products. For example, surges that reach microprocessor or memory components can destroy expensive parts, and erase critical data or programming. To prevent such losses to key components, many electronic products now include surge protection circuits. Resistors, when placed within these electronic surge protection circuits, can prevent sudden current or voltage changes from damaging valuable electronic components.
