Coiled Wire Resistors

Coiled Wire Resistors
ceramic insulators

Description

These resistors are constructed by coiling wire and supported by ceramic insulators on a steel strip.The resistive element is of stainless steel, fecral or Nickel Chromium. The standard end terminal is welded or screwed firmly to the resistive element,which provides good electrical connections to the resistive elements.
