Product Name: GPO-3 fiberglass reinforced polymer laminate
Product Description
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 Glass Polyester Laminate
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
