Product catalog summary

Overview
This document provides an overview of the range of solutions offered by Leroy-Somer SAS for power generation, specifically focusing on hydroelectricity. It highlights the company's expertise in providing innovative and reliable solutions for alternators, generators, and frequency inverters.

Alternators
The alternators offered have voltages up to 15 kV and power ratings up to 20 MW, with rotational speeds ranging from 250 to 1500 rpm. They are adaptable for various projects, can be installed on-site, and are compatible with any type of turbine. The design accommodates horizontal, vertical, and inclined shafts, and can handle significant radial and axial forces. They are built to withstand overspeed and offer high efficiency, flexible reactive power management, and a wide range of options and instrumentation.

Generators
Generators are available with voltages up to 690 V and power ratings of 1500 kW for asynchronous generators and 400 kW for magnet generators. They operate at speeds from 600 to 1500 rpm and offer IP23 or IP55 protection. Like alternators, they are compatible with any turbine type and shaft orientation, designed for overspeed resistance, and optimized for IE2 or IE3 efficiency. A variety of options and instrumentation is available.

Frequency Inverters
The frequency inverters feature a modular cabinet design, supporting a range from 100 to 2800 kVA. They are suitable for wound synchronous alternators, cage induction generators, and standard or magnet low-speed generators, with voltages of 400 or 690 V. Cooling options include air or liquid, and they comply with harmonic distortion and GRID CODE requirements. Features include a touch screen for supervision, an ETHERNET card for remote control, and built-in overspeed control. Benefits include increased production time, adaptation to hydraulic conditions, and optimized use of second-hand turbines.
