NP613

NP613 is constructed from electrical grade of kraft paper and a specially modified thermoset epoxy resin system. The product offers good dimensional and thermal stability, as well as a low power factor. NP613 is designed to be used in tap changers, coil support plates, and terminal panels for transformers and their accessories.

NP643

NP643 is a thermoset material constructed from electrical grade kraft paper and a specially modified high temperature epoxy resin system. The product offers good dimensional and thermal stability, electrical insulation, and a low power factor. NP643 is designed to be used in tap changers, coil support plates, and terminal panels for transformers and their accessories.

NP670

NP670 is composed of an epoxy resin system combined with a cotton linter paper for form a low-cost alternative to NEMA CEM-1 materials. A non-NEMA grade, this paper epoxy composite offers properties similar to those of NEMA FR-3, but does not meet permittivity, water absorption, and dissipation factor requirements. The product can be punched at room temperature at thicknesses up to 0.093 inch.
