NEMA Grade GPO-3 laminates are the industry standard for flame and arc/track resistant electrical insulation and 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. In addition, the excellent combination of high strength, flame resistance, and low smoke generation has given it application in many other areas such as transit and marine where safe, yet economical materials are required.
Flame resistance meeting UL 94V-O
Mechanical Strength
NEMA Grade GPO-3 laminates can be machined, punched, drilled, milled, sawn, sanded, sheared or routed. Assembly by bonding, metal screws or rivets are also possible. High-impact HongCheng 's fiberglass-reinforced polyester laminates won't shatter. Rigid laminates provide structural support as they insulate.
