Silicon coated wirewound resistors

Tested for quality & performance, our Silicon coated wire wound resistors are widely used across industries. We manufacture & export silicon coated wire wound resistors that are developed according to client's requirement & application areas.

Fixed Type & Adjustable Type Wirewound Resistors

In this type resistor is wound with Copper Nickel or Nickel Chromium wire on ceramic tube and then coated with high temperature non-flamable silicon coating. These resistors are suitable as loading resistors, braking resistor, capacitor discharge & many more application.
