Introduction ROLEX  make resistance boxes are designed to meet requirements of A.C & D.C. application for E.O.T. Cranes, Winches, Rubber Mills, Flour Mills, Coal Mines, Cement Mills, Power Plants, Conveyors, Coke Oven, Blowers etc. for Speed control and developing Starting Torque. Assembly and Function Rolex punched Steel resistance boxes Consist of Grids Punched from Nickel Chromium Steel Alloy Sheet. These grids are shock and vibration proof. These resistors are specially suited for Steel mill duty. Coal mines etc. These resistors are available in a wide range of Current ratings from 7 Amps to 800 Amps continuous. The series connection between adjacent grids is by means of copper jumpers. The resistors, after overloads of moderate duration become red hot but no damage is caused and retains their shape after overload disappears. Features: Economical Less Weight Spares Easily Available Easy For Maintenance Special Anti-vibration method adopted

ROLEX make Resistance Boxes are designed to meet requirements of AC & DC application for EOT Cranes, Winches, Rubber Mills, Flour Mills, Coal Mines, Cement Mills, Power Plants, Conveyors, Coke Oven, Blowers etc. for Speed control and developing Starting Torque.

“STERLING” Grid type Resistance Boxes are usually used with slip-ring [Wound Rotor] Motors [AC and DC] to provide control of starting torque, starting current and speed. They are designed to meet different classes of service, in various applications where slip-ring motors are used such as Conveyors, Screws Feeders, Steel Rolling Mills, Rubber Mills, Cranes, Hallagues, and Compressors etc. Desired control operation of Slip-ring Motors is obtained through external connections of appropriate values of Resistance into the Rotor slip-ring circuits. Slip-ring [Wound Rotor] Motors can operate with an infinite number of different speed, torque or current characteristics. Different performance criteria are obtained by the selection of external resistance which is connected into the slip-Ring circuit. “STERLING” Grid type Resistors are custom designed and manufactured to suit customers specific requirements, whether for starting duty or for continuous-speed-duty operations, in accordance with relevant BSS, NEMA or IS specifications. Rating / Duty Cycle  The Resistances are designed and manufactured to suit rating and duty cycles as required by the customer in his application and temperature rise does not exceed the limit specified in BSS 587-1957. Operation “STERLING” Resistances may be operated through Drum Controllers or by Master Controllers with associated contractor gear or with Timers and contractors in Slip-ring Motor starter panels. Construction “STERLING” Resistance Boxes Manufacturer are assembled with stainless steel wire grid type or punched stainless steel type elements, which are restless, unbreakable, and capable of withstanding mechanical shocks and vibration. The grids are mounted on high tensile steel rods insulated with heat resistant Mica tubes. These assemblies are mounted in well ventilated sheet steel housings, ensuring low temperature rise. All Resistance steps are terminated on a common terminal strip which facilitates installation and wiring.
