Resistors type ‘SS’ are manufactured from Stainless Steel (AISI 304), 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.

Resistors type 'PSS' are manufactured with grids punched out from Stainless Steel Plate (AISI 304). Each Resistor Grid has provision for termination which helps in changing the step Resistance Values of a given Resistor Assembly with out dismantling the whole assembly. These grids retain the end of the Grids and still remain cool which eliminates the hot spots from developing.

An Earthing Resistor is primarily a safety device. It drastically reduces shock hazards to personnel and equipment. We have, therefore, developed Earthing Resistors for your benefit. Grids are manufactured from a special alloy of stainless steel which makes them rustless and unbreakable thus eliminating maintenance problem and suitable for installation in outdoor atmosphere.
