Features & benefits

Safety and fire resistance: Cast‑resin insulation eliminates combustible transformer oil, reducing fire risk and making the unit safer for indoor and densely occupied spaces.
Low maintenance: Dry construction minimizes routine maintenance and removes oil leak concerns.
High reliability: Copper windings and silicon steel core ensure efficient performance and long service life.
Thermal performance: F‑class insulation and 100 K temperature rise rating for robust thermal endurance in demanding environments.
Flexibility: Off‑circuit tap changer provides precise voltage adjustment for site conditions and load variations.
Standards compliant: Designed and manufactured to IEC 60076 for global compatibility and quality assurance.
Quiet operation: Dry‑type construction and AN cooling reduce noise compared with oil‑filled units, ideal for noise‑sensitive locations.
