From Wikipedia, the free encyclopedia. Polyurethane, epoxy resins, polyethylene terephthalate, and other materials that have shown usable lifetime at this temperature.

Already Subscribed to this document. UL Knowledge Services workshops are designed for and intended to serve individuals using and relying upon UL services. Electrical machines are usually designed with an average temperature below the rated hot-spot temperature to allow for acceptable life. The major technical changes with regard to the previous edition concern the fact that this edition is an amalgamation of the third edition of this standard together with IEC Get your critical conformity assessment questions answered by standards experts from UL, the leaders in standards development.

You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

Silicone elastomers, and Class inorganic materials with high-temperature binders, or other materials insukation usable lifetime at this temperature. Click here for terms and conditions Workshops – Latin America.

Participants should have 06085 basic understanding of UL polymeric material requirements, especially those related to the use of insulation systems. We have no amendments or corrections for this standard. In addition, UL Knowledge Services reserves the right to change, reschedule or cancel any workshop at any time.

Insulation system

What is an Electrical Insulating Material, and how is it evaluated? There are five categories of insulaton used by the three different classes of equipment; functional, basic, supplementary, double and reinforced. The topics covered in this workshop are: It establishes the criteria for evaluating the thermal endurance of either electrical insulating materials EIM or electrical insulation systems EIS.

UL Knowledge Services reserves the right to limit workshop attendance strictly to the foregoing. NEMA standards Electrical safety.

You may delete a document from your Alert Profile at any time. This International Standard now distinguishes between thermal classes for electrical insulation systems and electrical insulating materials.

This standard is not included in any packages. Subscription pricing is determined by: As for Class B, and including teflon. By using this site, you agree to the Terms of Use and Privacy Policy. Standards Subsctiption may be the perfect solution. Can a specific application insu,ation a material that functions as both?

Retrieved from ” https: Older editions of standards listed materials to be used for the various temperature classes. Modern editions of standards are proscriptive, only indicating that the insulation system must provide acceptable life at the specified temperature rise. Please first verify your email before subscribing to alerts. The electrical insulation system is sometimes referred to as insulation class or thermal classification.

Standards Subscriptions from ANSI provides a money-saving, multi-user ic for accessing standards. This standard is applicable where the thermal factor is the dominant ageing factor. Your Alert Profile lists the documents that will be monitored. Inorganic materials such as mica, glass fibers, asbestoswith high-temperature indulation, or others with usable lifetime at this temperature. Add to Alert PDF. If the document is revised or amended, you will be notified by email.

It also establishes the procedure for assigning thermal classes. Need more than one electtrical As eelctrical voice of the U.

Class materials with binders stable at the higher temperature, or other materials with usable lifetime at this temperature. The electrical insulation system for wires used in generatorselectric motorstransformersand other wire-wound electrical components is divided into different classes by temperature and temperature rise.

UL, the industry leader in standards development, is available ineulation help you understand the requirements in this new standard. UL Knowledge Services accepts the following forms of payment for registration: This standard is also available to be included in Standards Subscriptions.

Views Read Edit View history. 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 more difficult to cool rotor winding may be Class F.
