High Power Coiled Wire Resistors

About High Power Coiled Wire Resistors

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 ofHigh 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 ChromiumThe 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 resistanceWith stands severe short time overloadsReliable terminalsResistors can also be supplied in enclosureCustom built resistors can be madeEasy to assemble as a bankCloser tolerance available.Reliable terminalsWith stands severe short time overloadsHigh temperature ceramic core resists vibration and shockLow temperature ceramic coefficient elements for durable resistanceThese can also be supplier in enclosureCloser Tolerance availableEasy to assemble as a bank Applications: These are utilized in combination with appropriate control device to accelerate, dynamic braking of motors. These resistors are also employed as neutral grounding resistors, DC and AC dynamic braking load banks, current limiting and blast for mercury vapor lamp. These products are also ideally suitable for utilize in the secondary of AC wound rotor motors for accelerating speed regulating services.
