Product Description
We are recognized as one of the leading manufacturers, exporters and suppliers of qualitative series of Coiled Wire Resistors. These resistors are designed and manufactured in accordance with industry norms using coiling wire that is finished with ceramic insulators on a steel strip. The offered resistors are utilized in combination with appropriate control device to accelerate, dynamic braking of motors. We offer these Coiled Wire Resistors in varied technical specifications as per the requirements of clients.
Coiled Resistors of High Power 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 and terminal is welded or screwed firmly to the resistive element, which provides good electrical connections to the resistive elements.
Specifications:
The resistive element is of Nickel Chromium or fecral, stainless steel.
The standard end terminal is screwed or welded firmly to the resistive element, which renders excellent electrical connection to the resistive elements.
Features:
Very Economical
Low temperature coefficient elements for more stable resistance
With stands severe short time overloads
Reliable terminals
Resistors can also be supplied in enclosure
Custom built resistors can be made
Easy to assemble as a bank
Closer tolerance available.
