NE-F1 Insulation System

NE-F1 Class F (155°C) Electrical Insulation System

Electrical Insulation Systems are invaluable to motor and transformer designers because they eliminate the need for long term component testing. New England Wire Technologies’ custom cable capabilities combined with the regulatory approvals of NE-F1 means we can provide you with high-performance winding wire solutions to meet the unique design challenges associated with today’s windings.

Technical Information

Our NE-F1 Electrical Insulation System was developed as the solution to cost, size, and time-saving requests from our customers. Extensive research and component testing allows us to provide a complete range of materials that are ideal for transformer, motor, and coil designs. Consequently, coil manufacturers are given more freedom in their device designs because they are not limited to a narrow range of materials. This design freedom leads to high efficiency, smaller, lower-cost devices that can be brought to market without long-term testing delays.

OBMW2 E132708 is approved for use in our NE-F1 system, which allows larger Litz wire sizes (6AWG and larger) into the insulation system – a major differentiator from other insulation systems. This category is intended to establish, without additional tests, the interchangeability of magnet wire with similar film coatings and equal or higher thermal ratings into recognized insulation systems that have been investigated under the thermal aging programs of UL.

The NE-F1 insulation system contains 6 tables of materials and hundreds of major and minor components to support any application.

Highlighted components include:

  • New England Wire Technologies’ NEWind® Multi-layer Winding Wire product line which is designed specifically to eliminate the need for separate ground, interwinding, and turn insulation resulting in a smaller device that performs equivalent to or better than a bulky and costly larger device.
  • A wide variety of enameled magnet wires of various temperature classes and base/top coats from multiple manufacturers
  • Ground and interwinding insulations from 3M, DuPont, Sumitomo, Celenese, and others
  • Tapes from 3M, Intertape, Neptco, Nitto Inc., P. Leo, Saint Gobain, and more
  • Sheet materials from 3M, DuPont, Von Roll, and others
  • A wide variety of bobbin materials, spacers and wedges, tubing and sleeving, potting compounds, and varnishes

This diverse selection of materials ensures that NE-F1 will be suitable for most Class F devices, thus reducing the need for multiple Electrical Insulation Systems.

Additional materials may be added in certain circumstances. We are happy to discuss additional options with you.
