High Power Punched Grid Resistors

These type of resistors use sheets of Nichrome or Fecral or Stainless Steel as resistive material. These sheets are punched to required Ohmic values and then assembled on tie rod with ceramic support and insulation as module. Such multiple modules are assembled in an enclosure to achieve required power.
