Insulation systems for transformers and e-motor manufacturers

Insulation systems have significant savings potential for producers of components when customers or countries that require UL certification are being supplied. By using only UL-listed components (coil carriers, impregnating resin, enamelled wire, adhesive insulation tape) for a transformer, for example, the certification test can be simplified and, in particular, it can be shortened significantly.

Insulation systems bring together insulation materials that have been inspected and tested, by means of the sealed tube test for example.

Several adhesive insulation tapes from CMC Klebetechnik are approved for use in the following insulation systems (class B/F) made by DuPont

  • Class 130 Crastin® PBT, Mylar®, Nomex®, Herberts® Electro C190HE

  • Class 155 Crastin® PBT, Mylar®, Nomex®, Herberts® Electro C290HE

  • Class 130 Rynite® PET, Mylar®, Nomex®, Herberts® Electro R150HE

  • Class 155 Rynite® PET, Mylar®, Nomex®, Herberts® Electro R201HE

  • Class 155 Rynite® PET, Mylar®, Nomex®, Herberts® Electro R203HE

  • Class 155 Zytel®, Crastin® PBT, Mylar®, Nomex®, Herberts® Electro CZ255HE

  • Class 130 Zytel®, Mylar®, Nomex®, Herberts® Electro Z130HE

  • Class 130 Zytel®, Mylar®, Nomex®, Herberts® Electro Z150HE

  • Class 155 Zytel®, Mylar®, Nomex®, Herberts® Electro Z200HE

This site comprises a comprehensive database from Underwriter Laboratories containing the UL-listed insulation materials.

The EIS-listed tapes include the types:

CMC 10966, 10820, 65120, 65100, 70100, 70110, 80725, 16100, 84170, 84160, 84150, 65768, 16701, 18102, 16700, 17713, 65767 (materials used: polyester, Nomex, polyester fleece, Kapton, crepe paper, glass fabric).

There is a large number of other insulation systems that use adhesive tapes from CMC Klebetechnik but which have been submitted to UL by individual customers and are not available for general use.

UL 510 and IEC 60454

The two standards UL 510 and IEC 60454 apply to adhesive types (also previously DIN 40633, VDE 0340).

UL 510 and IEC 60454

Principle of the test for flammability:

Three layers of adhesive tape are wound so that they overlap on a steel rod. A defined flame is then applied to the test sample five times for 15s with 15s pauses in between. Passed if (short version): No continued burning after 60s and no dripping of burning or smouldering material in any of the five flame treatments.

Test results if passed: flame retardant

The UL-Standard UL-94-VTM

Suitable for plastics in the form of sheets or film

Odoo CMS- Sample image floating

A test sample (12.7 mm) suspended in a vertical position is brought into the test area and a flame is applied with a Bunsen burner. In the case of thin materials (= TM, films), the test sample is clamped in a frame that is designed to prevent the sample from rolling up when the flame is applied. Normally this test is intended for materials over 2 mm in thickness and not for adhesive tape.

A group of films with low flammability and very good self-extinguishing properties is product group CMC 27xxx (polypropylene films with UL 94 - V0 classification). Nomex and Kapton adhesive tapes also have similarly effective properties.

Results:

  • V-0 Flame extinguishes within 10 seconds

  • V-1 Flame extinguishes within 30 seconds and no burning material drips down

  • V-2 Flame extinguishes within 30 seconds but it may drip

  • DIN 40633: Flammability classes

  • Bu1 - Bu3 Bu1 and Bu2 as above

  • Bu3: burns for longer than 30 seconds, but extinguishes within 60 seconds

Corresponds to UL 94 V test, but the test sample is placed horizontally into the test flame. This test is less demanding in terms of the self-extinguishing properties of the material.

Typical requirements for electrical products in external applications according to UL 746C (e.g. solar inverters):

UL 94 VTM0, 5kV disruptive discharge voltage, CTI=2, HAI=3, HWI=4

UL 94 VTM2, 5kV disruptive discharge voltage, CTI=2, HAI=2, HWI=2

Further information, including about the film properties, can be found via the "Link to UL" (enter the file number in the search window on the UL site) or directly from the manufacturer via our list of links (under “General Information”). The adhesives used are usually designed for a continuous temperature of at least 130 °C. Many of our UL-recognised adhesive tapes are tested to UL 510 and are often flame-retardant. With many films (e.g. Kapton(r)) there are variants that are designed for special requirements, such as corona resistance, heat dissipation or tracking resistance. Almost all of the adhesives are characterised by very good resistance to impregnating agents. In view of the wide variety of impregnating agents, however, it is not possible to make a general statement. Further information on working with adhesive tapes and the adhesives used.

Note on “flammability”: UL94 is the standard/norm for insulation materials. The additional H means “horizontal”, and V means “vertical” positioning of the test object during the flame test. “VTM” indicates that a thin insulation material (classically a film) was tested in vertical position. The standard/norm for adhesive tapes is UL 510. The test set-up differs in that the adhesive tape is stuck to “something” (a steel bar) as it would be in subsequent application and a flame is then applied (similar to IEC 60454-2).
