Neutral Grounding Resistors (NGR) are used for the low- and high- ohm grounding of the neutral point in medium voltage grids. Our grounding resistors consist of the resistor banks with resistor elements made from cast iron with or without surface protection or steel grid elements. This list comprises cast iron resistors of the system GINO. Alternatively, also resistors with stainless steel elements can be offered and manufactured. One or several resistor banks are installed in an insulated module and one or several modules are arranged in one housing. The housings are made from welded sectional steel frame with steel sheet cladding. 3-coat painting systems with 2-component paints protect the surface. Standard color is RAL 7032.
