AC-DC Variable Supplies

Introduction We design and manufacture a wide range of variable voltage supplies from 0-11 kV or any desired voltage up to 5000 kVA. These variable voltage supplies are used for special purpose applications as well as testing. Advantages Automatic overload protection. Externally adjustable maximum output current Special circuits protection for equipment Easy current limiting adjustment. Our A.C. Variable supply equipment cosists of linear (Vertical) type Stepless On Load Rolling Contact Voltage Regulator along with a Series transformer (Double wound Transformer). The main load current passes through the series transformer and the voltage is regulated with the help of type voltage regulators, wound with heavy section of copper strip and fitted with carbon rollers. Our equipments are designed for 100% continuous duty cycle and it can withstand 100% overloading for half and hour and 20 times short circuit current for short duration of time.

Special Purpose Transformer

Jindal is specialized in manufacturing a variety of special purpose oil cooled transformers. One of the major products under this category is furnace transformer used in arc furnace duty applications. In case of large furnace transformers instead of radiators oil to water heat exchangers will be provided if specified. This system will help to solve the space problem in steel mills because the designs with heat exchanger occupy less space. The other special purpose transformers manufactured by us are transformers for variable speed drive, transformers for testing application, Transformers for unit grounding and motor starting auto transformers etc. In short our company offers total solution for all kind of transformer requirement.
