FIW Breakdown Voltage

Fully Insulated Wire

Breakdown Voltage Calculation acc. to FIW Standard IEC 60317-0-7

Test is done by cylinder BDV test acc. to IEC 60851-4.3.2. The minimum breakdown voltage has to be calculated for every specific FIW wire size using the increase by insulation and the specific V/µm-value from below table.

Nominal conductor diameter
mm		 Minimum specific breakdown voltage
V/µm increase
over up to and including at room temperature at 180°C
- - >0.100 81 56
0.100 0.355 76 53
0.355 0.500 70 49
0.500 1.000 53 37
1.000 1.600 47 33

NOTE: The specific breakdown voltage is the result of the quotient of the measured value and enamel increase.

Example of formula for calculation of breakdown voltage (BDV):

BDV = min. increase *min. spec. BDV in V/μm

Example: 0.2 mm FIW6 with min. OD 0.303 mm

min. increase = min. OD - nom. dia. = 0.303 mm - 0.2 mm = 0.103 mm = 103 μm

=> BDV = 103 μm x 76 V/μm = 7828 V

Calculated Minimum Breakdown Voltage at 20 °C acc. to FIW Standard IEC 60317-56

Comments on different BDV standards

  • The actual version of the Transformer Standard IEC 61558-1 gives much lower values than IEC 60317-0-7.
  • The specific voltage per micron is given acc. to IEC 60317-0-7 at room temperature, while IEC 61558 calculates values of 180 °C and a safety margin (0.85). Actually needed temperature of SMPS (Switch Mode Power Supply) is somewhere in between.
  • IEC 62368 follows the BDV values of IEC 61558, but does not specify 180 °C as test temperature as IEC 61558.
