Organization: NEMA
Publication Date: 1 January 2020
Status: active
Page Count: 18
scope:

This Standard covers composite suspension (tension) insulators with a minimum section length of 46 inches (1168.4 millimeters) made of a fiberglass-reinforced resin matrix core, polymer material weathersheds, and metal end fittings intended for use on overhead transmission lines for electric power systems. Mechanical and electrical performance levels specified herein are requirements for new insulators.
