Abstract
A dry type electrical insulation is provided. The insulation includes a base fiber having an outer surface and a first melting point and a binder material, coated onto the outer surface of the base fiber, having a second melting point. In this insulation, the second melting point is lower than the first melting point. A dry type insulation matrix is also provided. The insulation matrix includes a plurality of composite fibers having a base fiber having a first melting point and a binder material co-extruded therewith, having a second melting point. In this insulation matrix, the second melting point is lower than the first.
