Design


Resistors consist of three protective resistor elements fixed in an insulating frame of glass fiber plastic. Each element is assembled from conductive disk-shape elements made of composite material ECOM.


RC circuit resistors with required voltage as well as RC circuits can be manufactured on request.


RC circuit is a resistor in an insulating frame of glass fiber plastic placed on base insulators. A capacitor bank is located on the top cover.
