RAL1001 beige Insulating Epoxy Coating for single conductors
In need of insulated copper or aluminum conductors for tight-fitting, durable bus systems, Storm Power Components provides the expertise, capabilities and equipment to manufacture high dielectric, epoxy powder-coated bus bar.
Epoxy Powder-Coated Insulation offers a high dielectric strength while creating durable insulation, impervious to most elements allows for closer busbar location in a system ideal for single conductors or multiple conductor assemblies that may have numerous forms. Epoxy powder coating is also well suited for insulating thick conductors, in addition to conductors with multiple electrical contact points.
Epoxy powder coating is a free-flowing, thermosetting dry powder. Think of this process as a way of "melting" paint over a bisbar's surface to create a durable, protective surface with thickness ranging from 6 to 120 mils or .006 to .120 inches. When the epoxy powder cures, a cross-link occurs increasing molecular weight and insulation capability.
Epoxy powder is chemical resistant and one of the oldest powder paints used in the electronics industry. It not only protects against corrosion but carries a high insulation rating of 800 volts per mil (.001 inches) at a minimum of 10 mil (.010 inches). Due to safety consideration it is recommended that a High-Pot test is preformed rather than rely on film thickness.
Tensile strength on raw and plated copper bar is in the range of 7500 PSI. UL rating is 130 Cº. Epoxy powder coating's high dielectric strength can be varied based on the application process, thickness and component preparation.
