A transformer bushing is a critical insulating component designed to safely carry high voltage current through the grounded tank of a transformer. It provides an insulated path for electrical conductors to pass through grounded barriers without compromising dielectric performance or structural integrity. Used in both power and distribution transformers, transformer bushings are essential for efficient energy transfer and system reliability.

Engineered for high mechanical strength and excellent thermal endurance, transformer bushings are typically manufactured using porcelain, epoxy resin, or a composite polymer material. They are available in oil-filled, resin-impregnated, or dry-type configurations, suitable for a range of indoor and outdoor transformer applications.

These bushings are built to withstand environmental stress, electrical surges, and mechanical loads, while ensuring minimal partial discharge and high insulation resistance. Available in a variety of voltage ratings and mounting configurations, transformer bushings are compatible with international standards such as IEC, ANSI, and IS.
