Digard® Insulation
 Digard® is a specially-developed epoxy powder used in the riser insulation system. The electro statically applied powder is preferentially attracted to the riser edges. As a result, the insulating material is actually thicker at critical edge areas. This coating is applied to the armature when hot, allowing the powder to melt and flow. This smooth, void-free surface provides long creepage paths and prevents carbon dust from adhering, thus eliminating the major cause of low insulation resistance in DC machines. |
