Description
CES also specializes in manufacturing three-phase dead-front transformers for commercial, industrial, and utility applications. The utility market sector has adopted the more user-friendly dead-front terminations and connection systems. The dead-front technology protects the utility technicians from exposure to live HV terminals and energized equipment.
