RIP Transformer Bushing

Designed for modern power systems, ZDVolt’s RIP (Resin-Impregnated Paper) bushings represent the next generation of dry-type condenser bushing technology. These bushings ensure long-term durability and operational efficiency, making them the ideal choice for high-performance, low-maintenance transformer installations.

Engineered with resin-impregnated crepe paper insulation, these bushings are completely leakage-free, non-flammable, and deliver excellent thermal and electrical performance – leading to superior reliability and environmental sustainability.

By end of 2025, ZDVolt’s RIP bushings has 20,000+ pieces installed worldwide
