Coiled Wire 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 lamp.
