Inorganic materials such as mica, glass fibers, asbestoswith high-temperature binders, or others with usable lifetime at this temperature.

It also establishes the procedure for assigning thermal classes. Polyurethane, epoxy insulafion, polyethylene terephthalate, and other materials that have shown usable lifetime at this temperature. UL Knowledge Services accepts the following forms of payment for registration: What is an Electrical Insulation System, and how is it evaluated? Silicone elastomers, and Class inorganic materials with high-temperature binders, or other materials with usable lifetime at this temperature.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Older editions of standards listed materials to be used for the various temperature classes. As the voice of the U. UL, the industry leader in standards insultaion, is available to help you understand the requirements in this new standard. Click here for terms and conditions This standard is also available to be included in Standards Subscriptions.

Modern editions of standards are proscriptive, only indicating that the insulation system must provide acceptable life at the specified temperature rise. UL Knowledge Services reserves the right to limit workshop attendance strictly to the foregoing.

Can a specific application utilize a material that functions as both? 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.

Organic materials such as cottonsilkpapersome synthetic fibers [6]. Please first verify your email before subscribing to alerts.

Electrical machines are usually designed with an average temperature below the rated hot-spot temperature to allow for acceptable life. There are five categories of insulation used by the three different classes of equipment; functional, basic, supplementary, double and reinforced.

From Wikipedia, the free encyclopedia. It establishes the criteria for evaluating the thermal endurance of either electrical insulating materials EIM or electrical insulation systems EIS. We have no amendments or corrections for this standard. Participants should have a basic understanding of UL polymeric material requirements, especially those related to the use of insulation systems. Retrieved from ” https: Fink and Wayne H.
