HT Distribution & Power Transformers
Heavy-duty oil-cooled HT distribution and power transformers built to IS 2026 standards for industrial substations, high-voltage power transmission, and plant electrical distribution infrastructure.
What is an HT Distribution & Power Transformer?
High Tension (HT) Distribution and Power Transformers are industrial-grade transformers designed to handle high utility voltages (such as 11kV or 33kV) and step them down to standard low-voltage plant operating levels (433V/415V 3-Phase). Positioned at utility intake substations and heavy industrial plant yards, these transformers feature ONAN (Oil Natural Air Natural) cooling, high-grade copper windings, and robust insulation tanks to provide safe, reliable, and continuous power distribution across vast manufacturing facilities without breakdown.
