TEWACWOLONG
Water-Air Cooled HV Motor .
TEWAC (TEAWC) Series Totally Enclosed Water-to-Air Cooled High Voltage Three-Phase Induction Motor
TEWAC covers Wolong's water-to-air cooled high-voltage motors, the most powerful of its platforms: 280–40,000 kW, 3000–13,800 V, frames H355–1400, 300–3600 rpm. IC81W or IC86W cooling removes heat through water and keeps the frame compact at outputs beyond the reach of air cooling; protection up to IP66, efficiency IE4 and above, vibration ≤1.2 mm/s. Ex ec, Ex pxb, Ex pzc and Ex tb versions are available. Ambient range −20…+40 °C, −40…+60 °C on request. Wolong's own material uses both spellings, TEWAC and TEAWC.
