The PNACHO-D 160 is a three-phase, vacuum-cast epoxy-resin dry-type transformer for 6.3 kV networks in buildings and industrial plants where fire safety matters: self-extinguishing class F1, climatic class C3 and environmental class E3 to IEC/EN 60076-11. It complies with Ecodesign Tier 2 – Regulation (EU) 2019/1783 – and needs no oil, no bund and no fire-suppression system.

Testing and conformity

Every unit undergoes routine tests to IEC 60076: no-load loss and current, load loss and impedance at 75 °C, winding resistance, voltage ratio and vector group, induced and applied voltage withstand, insulation resistance. Type tests (lightning impulse, temperature rise, short-circuit withstand, sound level) are available on request. Each transformer is delivered with test report, EU declaration of conformity (CE – LVD, EMC, RoHS, Ecodesign) and operating manual.

Applications

Hospitals, data centres, shopping centres, high-rise and public buildings, tunnels and underground installations, industrial halls, indoor substations.

Delivery and warranty

Standard configurations are available from European stock with short lead times; other voltage ratios, vector groups, copper windings and accessories on request. 5-year warranty. Delivery to any EU country, technical support in English, German and Polish.
