Silicon Glass Cloth Laminate Sheet (NEMA G7)

Nema G7 Silicon Glass Cloth Laminate Sheet

Properties

Silicon Glass Cloth Laminated Sheet (SiGC, NEMA G7 sheet) is made of several layers of glass cloth impregnated with silicon resin by processing under heat and pressure, the natural color is typically cream to white which has excellent heat and arc resistance. It can be used as a slot insulation in high temperature motor, arc clapboard in the switch and so on.
