Tapchanger For Transformer

On Load Gears offers a transformer Tapchanger, Type PG. The Type PG is a double compartment tapchanger, with a diverter switch, and a tap selector. The design is based on modular principle, so that diverters of various voltages and current ratings can be combined with selectors of different operating positions, sizes, and current carrying capacity. Such a modular construction principle enables OLG to offer a transformer user the most appropriate tapchanger for each application. The tapchanger type PG is available in single phase execution and in three phase execution. Since the tap selector does not make, or break current, it can be built into the main transformer tank as part of core and coil assembly. This avoids the necessity of taking high voltage tapping leads out of the transformer tank, through a terminal barrier board. The tapchanger is available with insulation against ground to suit service voltage from 33 kV to 245 kV. The basic current rating of the diverter switch is 400 A. The tapchanger is driven by an external driving mechanism, through a system of horizontal, and vertical driving shafts, interconnected by a bevel gear. The mechanism box and the bevel gear are to be mounted by the transformer manufacturer on his transformer tank. The company also offers On Load Tapchanger, Porcelain Clad Outdoor VCB, Tapchanger Type ABS, Outdoor VCB - Porcelain Clad, etc.
