Description
MJHT and MJHRT are medium-voltage synchronous hydro-generators for small and medium hydroelectric power plants. The company positions itself as a reliable partner for individual solutions at hydropower plants of all types, and produces generators for Cross-Flow (Banki), Francis, Kaplan, Pelton and Turgo turbines, in horizontal or vertical versions. MJHT is an open design with IC01 cooling: power up to 11,500 kVA, voltage up to 15,000 V, frequency 50/60 Hz, 4–20 poles (more on agreement with the manufacturer), frame sizes 400–1250, degree of protection IP23, ambient temperature −15…+60 °C. MJHRT is a closed design with an air-water cooler IC81W: up to 11,000 kVA, up to 15,000 V, IP44 (IP56 on request), ambient 0…+60 °C, cooling water up to 40 °C. Voltage regulators: up to 6900 V, MGC I up to frame size 560 and MGC II above; above 6900 V, the digital D-Vo Light. Rolling or sliding bearings; standard IEC 60034; UL/CSA on request. Options for hydro-units: a special shaft end for direct connection to the turbine, a bearing assembly to take significant axial and radial turbine forces, a reinforced rotor for high runaway speed, horizontal or vertical shaft design, neutral current transformer, insulated bearing and earthing brush, 64R protection, air ducts for cooling air inlet and outlet, an additional flywheel for a specified moment of inertia, vibration sensors, a braking system and a lubrication system for sliding bearings.
