Resistance boxes are available for developing starting torque for motors for EOT Cranes, winches, rubber mills, conveyors, etc. Air cooled as well as oil cooled resistance boxes manufactured out of corrosion resistant nickel chromium alloy steels are available. The punched grid resistors are completely immune to shock and vibration. They function reliably under the worst operating conditions and are particularly suitable for steel mill duty. Wire grid resistance boxes can also be supplied. Apart from the application, motor rotor volts and rotor s are necessary for designing the resistance boxes appropriately.

Our range of resistance boxes starting resistors are used for both AC and DC applications. It is widely used for controlling and developing higher torque and are extensively applicable in:

We are engaged in manufacturing grid resistance boxes of motor and crane control resistors, load banks, resistance banks, neutral grounding cubicles / resistors and a variety of custom built power electrical resistors and associated control panels. Stainless steel grid resistances are highly recommended for use on crane and other machines due to its high mechanical, loss temperature co-efficient of resistance, high resistively, easy adjustability, requirement of less space, long life etc. Resistance Boxes Our range of resistance boxes starting resistors are used for both AC and DC applications. It is widely used for controlling and developing higher torque and have extensively applicable in:

The decade resistance box offered by us is provided with low contact resistance decade switches. Our decade resistance box is offered with total resistance that ranges from minimum 1 #8486; to maximum 1000 M #8486;. Specifications:

Ex - 241 Resistance Box Plug Type (Manganin Coils):

All the specifications of this resistance box plug type (manganin coils) are almost same as cat no.Ex-296 but the coils are wounded with double silk covered manganin wire with accuracy level of 0.5%. These equipment are also available is standard range also.

The resistance box we offer are of very good quality with accuracy level plusmn; 0.5% in two ranges plug type resistance box and dial type resistance box. Our resistance box are available in standard range also.
