CAST-RESIN TRANSFORMERS
Cast-Resin Transformers
[Standard]
Featuring excellent insulation performance of epoxy resin and a sectionalized winding design, this transformer provides superior impulse withstand voltage.
It eliminates the risk of fire or explosion caused by electrical arcs due to its inherent self-extinguishing properties.
Strong Short-Circuit Strength
The coils are vacuum-cast in high-quality epoxy resin, ensuring high mechanical strength and durability against short-circuit forces, external impacts, and abnormal vibrations during operation.
Fire Retardant
Epoxy resin insulation provides excellent flame-retardant characteristics with self-extinguishing capability, minimizing fire hazards.
Easy Inspection and Maintenance
With a simple structure and excellent moisture resistance, the transformer enables convenient inspection and maintenance without deterioration of insulation performance over time.
