Dry transformer-22/0.4kv 160kva. Dyn-11 (AL-AL)

Cast resin transformer (Standard)     It's characterized by good impulse withstand voltage with excellent insulation ability of epoxy resin and design of session dividing winding and has no fire or explosion risk by electric arc with its own self-extinguishing characteristics.          (1) Strong short-circuit force It has high durability for electric mechanical power, external shock and abnormal vibration on the disconnection because the coil of cast resin transformer is molded into Epoxy Resin in the high-degree vacuum. (2) Fire Retardant No fire risk and self-extinguishing ability using Epoxy Resin with excellent combustibility. (3) Easy inspection and maintenance Convenient maintenance without the insulation ability decrease because of simple design and good waterproofness.   Applicable Standard IEC 60076-11, KS C 4311 Frequency 50, 60Hz Insulation class B or F Temperature rise 80℃ or 100℃ BIL (kV) System Voltage Power frequency withstand voltage Impulse Voltage 24 7.2 3.6 0.6 below 50 20 10 3 95 40 20 - Primary voltage (kV) 22.9 6.6 33.3 0.6 below Tap voltage (kV) F23.9-R22.9- 21.9-20.9-19.9 F6.9-R6.6-6.3- 6.0-5.7 F3.45-R3.3-3.15- 3.0-2.85 - Secondary voltage (kV) 6.6, 3.3, 0.48, 0.44, 0.38, 0.22
