From Wikipedia, the free encyclopedia. UL, the industry leader in standards development, is available to help you understand the requirements in this new standard.

In large machines, different systems may be used according to the predicted temperature rise of the machine; for example, in large hydroelectric generators, stator windings may be Class B but the eletrical difficult to cool rotor winding may be Class F. Participants should kec possess a general understanding of insulation systems as they are used in motors, coils, and valves. Please first verify your email before subscribing to alerts. As for Class B, and including teflon. By using this site, you agree to the Terms of Use and Privacy Policy.

Participants should have a basic understanding of UL polymeric material requirements, especially those related to the use of insulation systems. This standard is not included in any packages. This International Standard now distinguishes between thermal classes for electrical insulation systems and electrical insulating materials.

There are five categories of insulation used by the three different classes of equipment; functional, basic, supplementary, double and reinforced. Need more than one copy?

Modern editions of standards are proscriptive, only indicating that the insulation system must provide acceptable life at the specified temperature rise. What is an Electrical Insulating Material, and how is it evaluated? UL Knowledge Services workshops are designed for and intended to serve individuals using and relying upon UL services. Older editions of standards listed materials to be used for the various temperature classes. Electrical machines are usually designed with an average temperature below the rated hot-spot temperature to allow for acceptable life.
