“ROHMS”  Resistors type ‘SS’ are Manufactured  from Stainless Steel (AISI 304) having temperature co-efficient of 0.094% per degC, wire formed grids, making them rustless, unbreakable and light in weight. there is provision at each grid to have a tapping, so that resistance value between steps could be altered. The required no of grids are put in series to get the required ohmic values. The assembly is supported of mica insulated steel rods with mica washers thus forming a stack. This stack of grid resistor can be mounted on a panel  or steel rod is bolted to the two sides.
