GPO-3 Sheet ,Red GPO3 Sheet ,Fiberglass laminate GPO-3
is A fiberglass reinforced polymer laminate. This material
is the industry standard for flame & arc/track resistant electrical
components. GP03 also offers an excellent combination of high strength,
flame resistance, and low smoke, flame, & toxicity generation.
GP03 is a NEMA approved material per NEMA procedure NEMA LI-1..
Combines high arc and track resistance, highly flame resistant. For use on 2500+ voltage equipment. 94V-O flame retardance rating. 22,100 PSI flexural strength. Red in colour

GPO-3 laminate performs well in electrical applications that require
high arc and carbon track resistance as well as flame resistance,
physical strength, and moderate heat resistance. Grade GPO-3 laminate
is used extensively in the making of phase and end barriers, insulating
supports, bus bar supports and mounting panels in switchgear and
other types of electrical apparatus. Grade GPO-3 is a UL recognized
product with a temperature index of 120 degrees celsius electrical
and 140 degrees celsius mechanical. Grade GPO-3 is produced in three
standard colors: red, black, and white and is molded in thicknesses
of 1/32?to 2 used for general purpose electrical and/or
mechanical applications where low cost is desired. GPO-3 can withstand
higher temperatures than GPO-1 or GPO-2, and has better electrical
