Epoxy resins for medium-and high-voltage switches are mainly used to manufacture various insulating components, such as insulators, insulating conduits, insulating cylinders, insulator brackets, or insulating partitions, solid-sealed poles, and solid switches. These insulating parts feature structural diversity—some have complex shapes and structures-along with diverse application scenarios and varied performance requirements. Such product diversity demands customized materials, for instance, to suit indoor or outdoor application environments; to meet different flame-retardant properties; to resist low, ultra-low, or high temperatures; to withstand salt spray, pollution, or chemicals; to be mold-resistant; and to be radiation-resistant.
