GPO-1 is an economical general purpose NEMA GPO-1 laminate that performs well in applications where good electrical GPOproperties, good physical strength, and moderate heat resistance are required, but where higher flame is not. GPO-1 is suitable for producing a variety of electrical insulating and support components including: barriers, mounting panels, brush holders, collars, wedges, and blocking used in rotating apparatus, dry-type transformers, and large switches. GPO-1 laminate works well in IEEE Class B operating temperatures. The standard color for GPO-1 is brown and its molded thickness is 1/32″ through 2.”,/p>
