Grup de rezistente fara carcasa Sir Resistor

Construction and execution
The resistive groups are realized through the assembly of elliptic or tubular cemented resistors or of uncoated wire-wound resistors or of resistive grids/plates.
Realizations with 2, 3 up to a maximum of twelve resistors are possible, depending on the type of resistor or you can supply banks of resistive grids/plates.
The power levels that can be obtained depend on the type and number of resistors used. Furthermore, the range of ohmic values achievable is also very wide depending on the connections that can be made (series or parallel). The only limits are the applicable voltages (maximum 12 kV) and the applicable currents (80 A), which depend on the geometric dimensions of the components (current passage sections), the maximum achievable insulation distances, the type of insulation present (single or double insulation stage), etc.
Subject to limitations in the powers obtainable, anti-inductive versions can be implemented for some types.
The environmental protection level of these groups is IP00, therefore they are open groups, which require protection systems not included in the supply (or they have to be included in more complex systems).
