sliding rheostats, adjustable resistors

The sliding rheostats are basically silicon coated and open type. In these types, one or more Silicon coated Resistor is used, as these heavy duty industrial type sliding Rheostats are used were the current has to be adjusted (increased or decreased) frequently and it is done through Hand operated pushing knobs or Rotating type wheel with handle connected to threaded rods. After the manufacturing process, using the perfect ohmic value two or more Resistors are combined together to reach the required value and then they are assembled in the suitable mounting brackets made of Aluminium or Mild Steel and sliding arrangements are provided as per customer specification. The Resistors are manufactured under strict supervision on each step of process i.e. right from selection of tube to the perfect size, selection of wires to attain the perfect value, the winding process, and finally the insulation and coating process by experienced engineers. The sizes of Rheostats varies from a min size of 152 mm L * 32 mm Dia to a max size of 457mm L * 51mm Dia and are available in single, double tube models, and in some special case four tube models are also available.Slider movement also can be operated by threaded rod by coupled with beveled gear suitable for panel mounting and controlled with wheel from front of the panel.

These resistor controlled directly by hand-operated knobs,operated by threaded rod & controlled with wheel from one end.
