HVDC Converter Stations & Valve Halls: Insulation Selection

Define DC wall-bushing insulation and interface duties before model selection.

Operating Conditions & Selection

HVDC Converter Stations & Valve Halls

Converter-station wall bushings require project-specific DC polarity, impulse, temperature, creepage and wall-penetration requirements. Review oil, gas or dry-core interfaces and request the matching test programme; fire-barrier duties require separate building-system assessment.
