Описание:
The MJV / MJHV series comprises high‑performance generators designed for power generation and standby/emergency applications. The MJV series operates at Low Voltage, while the MJHV series is designed for Medium Voltage applications. These generators deliver power up to 10000 kVA at voltages up to 15000 V. They are available in frame sizes from 315 to 1250, with 4 to 12 poles, and operate at 50 or 60 Hz. The generators feature a protection degree of IP44 (up to IP56 on request) and cooling method IC 611. They are designed to operate in ambient temperatures from -15°C to +60°C. The automatic voltage regulator (AVR) varies by frame size: E‑Vo up to frame 630; MGC II above for Low Voltage (Vn ≤ 6900 V); MGC I up to 560 and MGC II above; D‑Vo Light for Medium Voltage (Vn > 6900 V). Bearing options include antifriction bearings or sleeve bearings (on request).
