CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It provides the mechanical force to move the diverter switch contacts between tap positions while the transformer is under load, ensuring a rapid and arc-free transition.
Typical reference ranges include rated operating force of 500–1500 N, spring stroke of 20–50 mm, spring rate of 10–50 N/mm, operating temperature range of -40 to 85 °C, and mechanical life of 500,000 to 1,000,000 cycles. These must be confirmed for the specific model.
Common materials include high-carbon spring steel (e.g., SAE 1070/1095) or alloy steel for springs and linkages, bronze or brass for bushings and bearings, and engineering plastics for insulators and guides.
Relevant standards include ISO 4042 for surface treatment (zinc plating), IEC 60529 for degree of protection (IP54–IP65), and ISO 2768-m for dimensional tolerances. Compliance must be verified with the manufacturer.
