Cast Resin Dry-Type Transformer

Safety Without Compromise

Hartwerk Power cast resin transformers are designed for environments where fire safety and environmental protection are non-negotiable. Using Class F or Class H insulation systems with epoxy resin encapsulation, these units operate without cooling liquid — eliminating the risk of leaks and fire propagation.

Ideal for data centres, metro systems, hospitals, and offshore platforms where space is constrained and safety regulations are stringent. Every unit is vacuum-cast under controlled conditions to eliminate air voids, ensuring partial discharge below 5 pC across the winding.
