Description
The Fermi National Accelerator Laboratory (Fermilab) is seeking proposals for the supply of electrical steel coils. The coils must meet specific magnetic and electrical properties, including a coercive force (Hc) not exceeding 0.5 Oe and a core loss within 5% of the listed properties. The successful bidder will be required to provide coils that meet these specifications.
Some key points to consider include:
• The acceptance of Epstein testing per ASTM A348 for magnetic properties
• The correction of the statement regarding coercive force (Hc) and induction
• The acceptance of lower core losses and higher permeability
• The removal of the electrical resistivity test per ASTM A342
• The correction to the surface resistivity requirement in Table 5
