  • special case note
    Max. Voltage in Air is significantly lower. KJLC does not recommend these wires for air use.
  • special case note
    Max. Current depends strongly on use, especially for vacuum applications. If a coil is formed, a temperature test should be done. As an approximation, 1/3 of the given current can be assumed. As the heat dissipation is very low in vacuum, the cables will get hot with continuous use at the given values.
  • special case note
    Calculated value with conductance of 56 S m /mm² at 20°C.
  • special case note
    The electrical and thermal ratings specified are of safe operating limits determined by various factors including material properties, mechanical design, and the intended operating environment. All electrical ratings are based on operation with one side in dry atmosphere and the other side in vacuum of less than 1 x 10-4 Torr. All VacuCAD files as well as any dimensions shown or listed in our ordering tables do not include manufacturing tolerances and are provided for reference only.
