nVent delivers custom medium-voltage and high-voltage bus products trusted across industrial, commercial, and power generation environments worldwide. Our proven designs provide reliability and efficiency for continuous operations.

Our non-segregated, segregated phase and isolated phase medium‑voltage bus systems are engineered for reliability, safety, and long-term durability. Each system is fully customizable to meet your specific current rating, voltage rating, basic impulse level (BIL), and application requirements.

For the most demanding environments, our high-voltage bus systems offer a cost-effective, fully integrated solution for hydroelectric, renewable, and combined-cycle power plants. We design and install complete systems and coordinate interfaces with major generator, breaker, and transformer manufacturers, engineering each solution to fit tight installation constraints and right-of-way requirements.

Keep your operations running without interruptions with expert support, including:

  • Application-specific preventive maintenance (diagnostics, inspections, cleaning, testing, and replacement parts)
  • 24-hour emergency service when you need it most (Hyperlink to emergency service page: Bus Duct Emergency Service - Bus Systems
