Kapton insulated wire is designed for use in high & ultra-high vacuum applications. Kapton has high mechanical strength, excellent electrical insulation properties, and low outgassing rates making it ideal for use as an in-vacuum insulator.
Notes:
Notes:
Max. Voltage in Air is significantly lower, does not recommend these wires for air use.
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.
Calculated value with conductance of 56 S m /mm² at 20°C.
