Coiled Wire Resistors
Leveraging on our manufacturing
excellence & team of industry experts, we produce Coiled Wire resistors
to the domestic, as well as to the international marketplace. Our efficient
manufacturing techniques enables us to execute bulk orders of customized
resistors.
COILED RESISTORS
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.
FEATURES
- Very economical.
- Low temperature coefficient elements for more stable resistance.
- High temperature ceramic core resists shock and vibration.
- With stands severe short time overlaods.
- Reliable terminals.
- Resistors can also be supplied in enclosure.
- Custom built resistors can be made.
- Easy to assemble as a bank.
- Closer Tolerance available.

Application
These Resistors are used in conjuction with appropriate
control equipment to accelerate, dynamic braking of motors.
These resistors are also ideally suited for use in the secondary of AC
wound rotor motors for accelerating speed regulating services.
These resistors are also used as neutral grounding resistors. AC and DC
dynamic braking load banks, current limiting and blast for mercury vapor
