Selfbonding wire types

Self bonding Wire Types

General

There is a big variety of self bonding wire types available. The different base coats and self bonding overcoats are described in different standards, such as IEC 60317, NEMA MW 1000 or JIS C3202, which sometimes still use different test methods.
Under the respective standard the typical technical values are given for the different base coats such as Polyurethane, Polyester, Polyesterimide etc. and for different bond coats such as Polyvinylbutyral, Polyamide etc.

For easier comparison of products and the evaluation of their suitability for certain applications there is a tick-box below each of the product-codes and a "Compare Selected Items" button in the precolumn of the table. When this button is klicked, only the marked items are left over and appear side by side. This view of the table is also suitable for printing; use the options of your browser for this purpose, please using the "Show all" button makes the invisible products reappear again.

Thermal Stability in Hours [h] vs. Temperature in Degrees Celsius [°C]
Average breakdown voltage at 20°C
Calculation of average value Ds
Ds=t*Vµ(volt), with
Ds : breakdown voltage
t : increase with insulation, t = da - dnom, with
da : outer diameter
dnom : bare wire diameter
Vµ : Volt per micron insulation
Example
Test with cylindrical electrode
dnom = 0.071mm (41 AWG)
da = 0.083mm
t = da - dnom = 0.083 - 0.071 = 0.012mm = 12 µm
Vµ = 220 V/µm, therefore
Ds = 12µ * 220 V/µ = 2,640 V

FIW Length/Weight Calculator

Length in km per 1 kg and weight in kg per 1 km for FIW can be retrieved along with the breakdown voltage, too, using the FIW quick selection on the dimensions page. The weight for an arbitrary length and vice versa can be retrieved using the Length/Weight Calculator underneath.

After specification of the considered FIW by picking a nominal diameter and an FIW grade from the tables offered, any weight can be typed in and the length is calculated immediately and the other way around.

Breakdown Voltage (BDV)

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

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

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.

Selfbonding Wire, Selfbonding Copper Wire

General

Selfbonding enamelled wire (SB-wire), also referred to as bondable magnet wire, is film insulated wire
( Goto Enamelled Wire Types ) which is coated with an additional bonding adhesive.


Backlight microscope picture of SB-wire


After activating the bondcoat, the individual turns of the coil are bonded together to produce self-supporting coils ("air coils" without bobbin) or special coils for later processing.

Use of selfbonding enamelled wire offers advantages over conventional enamelled wire in certain winding applications, eliminating the need for bobbins as well as taping or varnishing steps.

Cross section of wound coil
(Lighter colour = insulation, dark colour = bondcoat)


In many applications such as high-power speakers or small motors, selfbonding wire can improve the performance and reliability. An important property of a selfbonding wire is the thermal stability of the wound coil at higher temperatures. A thermoplastic bondcoat will become soft at higher temperatures and begin to lose its bond strength, but

could also be processed, for example, to form another shape of a coil and be rebonded at higher temperature. A thermoset bondcoat has higher heat resistant properties, so will lose its bond strength only at a temperature that will destroy the enamel.


Selfbonding wire wound by hot-air and formed to rectangular shape


Because of the additional application of a bondcoat, selfbonding wires are more expensive than normal wires, which is offset by the value added.

Activation of the bondcoat may be achieved with either heat, or in some cases a solvent, or a combination of the two ( Goto Bonding Processes ).

Our Product Line

Elektrisola produces selfbonding wire with diameters of 0.010 - 0.50 mm ( Goto Technical Data by Size ). In addition to copper as a conductor material, other alloys are available, such as Aluminium or Copper Clad Aluminium for light weight coils or high tensile strength conductors for better durability ( Goto Metals ).


CCAW with bondcoat

Selfbonding wire types can be differentiated by the chemical basis of their coatings, primarily by their thermal properties, by their technical properties and by the preferred bonding method.

The basic selfbonding wire types offered around the world have differences mainly explained by the history of their development. Therefore Elektrisola offers selfbonding wire types for the 3 major continents
( Goto Selfbonding Wire Types ). In Asia, special high performance bondcoats formulated for use in specific Asian applications are also offered ( Goto High Performance Selfbonding Wire Types ).

In addition to standard selfbonding enamel types, ELEKTRISOLA has its own certified selfbonding enamel development for special applications. For example, in fine wire sizes, specialized ultra-high temperature selfbonding enamel types are now available, which can be wound with automated hot-air winding machines for fast and cost effective processing providing a major advantage to Elektrisola customers.

Production Process

The production process of a selfbonding wire is similar to a normal film insulated wire

( Goto Enamelling Process ), but needs 2 enamel applicators, one for the electrical insulation coating, and one for the bondcoat.

Bonding Process

The bondcoat adhesive on the outside of a selfbonding wire can be activated by heat or with chemicals. These bonding methods are described below.


Heat/Thermal Bonding:

All Elektrisola bondcoats can be activated by heat, either by directing hot air on to the wire during winding, by oven-heating of the wound coil, or by applying electric current to the wound coil after the winding cycle is completed. In any of these examples, the principle is to heat the winding slightly above the bondcoat’s melting temperature in order to activate the bondcoat and bond the wires together.


Hot-air Bonding during winding has the advantage of eliminating the secondary bonding operation. This method is cost effective and primarily used for wire sizes thinner than 0.200 mm. This method became much more popular over the last few years following the development of ultra-high temperature selfbonding enamel types.


Hot air winding


Oven Bonding is accomplished by heating the wound coil, which still remains on a fixture or tooling, in an oven at a suitable temperature and time sufficient to obtain uniform heating throughout the winding followed by a cooling cycle. Heating time is generally 10 to 30 minutes, depending on the size of the coil. Disadvantages of oven bonding are the longer bonding time, additional process steps, as well as the potential need for many winding fixtures.

Resistance Bonding is accomplished by applying electric current to the finished coil to electrically heat it by resistance to the proper bond temperature. Bonding voltage and time are dependent upon wire size and coil design, and therefore will need to be developed experimentally for each specific application. This method has the advantages of being quick and generating a quite uniform heat distribution. It is typically used for wire sizes thicker than 0.200 mm.


Solvent Bonding:

Some bondcoats can be activated by applying specified solvents during the coil winding process. Application of the solvent, usually via a saturated felt during winding ("Wet Winding"), causes the bondcoat to become very soft. This process requires the use of a fixture to hold the coil in place while the solvent is drying and the wires stick together. Afterwards, the coil should be heated in an oven cycle to evaporate any residual solvent, which, if left within the coil, might cause long-term coil failure, as well as to complete the adhesive curing process for optimum bond strength.

Technical Data by Size

Technical Data by Size

General

Technical values of enamelled wires often depend on the diameter of the wire.

Most important are the tolerances for resistance and outer diameter. These and other values are important as engineering support.

Different standards specify these values differently. Therefore the 3 major world standards are shown:

  • IEC 60317 for Europe and Asia
  • JIS C3202 for Asia
  • NEMA MW 1000C (inch) and NEMA MW 1000C metric (mm) for America
