The American-style 200A/600A insulating caps are designed for use on 200A/600A bushings' reserved openings or to seal bushings during maintenance when connectors have been removed. As an accessory component for bushings, they provide complete insulation and hermetic sealing protection for energized bushings, while offering dustproof and moisture-resistant sealing safeguards for de-energized bushings.
