Advance Material Science


NEMA G9 is similar to G5, but it can be used in high humidity applications. It has high mechanical strength and excellent electrical properties including high arc and heat resistance. It is also self extinguishing. It is used in the electrical industry in switch board panels, arc barriers, circuit breakers and as structural electrical parts both under regular and high humidity situations.
