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 silicone coating. These resistors are suitable as loading
resistors, braking resistor, capacitor discharge & many more
application.
Features
- Strong Terminals
- Resistance Value unchanged after long term use.
- Multi-terminal Types or adjustable types available.
- Non-inductive type available.
- Mounting hardware for all resistors available.
- Custom built resistors is our speciality.
