www.weg.net Manufacturing processes Insulation system WEG hydrogenerators are delivered with the WEG MICATHERM insulation system. This insulation system is based on the “Vacuum Pressure Impregnation” (VPI) system which was developed in cooperation with the most renowned suppliers of insulating material all over the world. Using special epoxy based resin, this insulation system ensures perfect winding insulation of the hydrogenerators and does not emit harmful gases into the environment. For many years, the VPI process has evidenced its efficiency and reliability in electrical rotating...

www.weg.net GH10 and SH10 hydrogenerators WEG produces hydrogenerators for all types of hydraulic turbines. For applications in Small Hydro Power (SHP) plants, WEG developed a standardized line of hydrogenerators that vary with the characteristics of each installation, thus expanding the application possibilities with great versatility. The GH10 line was developed aiming to meet the most common applications with smaller and simpler machines, i. e. for application of machines where not so high axial loading and inertia loads are present, no high runaway speeds are generated, etc. This...

www.weg.net GH10 line The GH10 line is an optimized hydrogenerator line aiming at high performance and cost reduction. Its application is suitable for conditions where high inertias are present and the turbine + hydrogenerator arrangements ensure that the hydraulic loads are supported by the hydraulic turbine and not by the hydrogenerator bearings. Range of application The GH10 hydrogenerator line can be supplied with the following technical data: g Output range: 500 kVA to 4500 kVA g Number of poles: 4 to 16 g Rated voltage: 400 V to 3300 V for 50 Hz 480 V to 4160 V for 60 Hz Note: Other...

www.weg.net SH10 line The SH10 line comprises a compact and rugged hydrogenerator line designed to meet the different application demands/turbine + hydrogenerator arrangements. Thus, the SH10 line was designed with the purpose of improving the electrical and mechanical design allowing to operate the generator with higher inertia loads in compact types, meet higher hydraulic loads and withstand adverse conditions such as load rejection or high runaway speeds without losing the reliability of WEG products. Range of application The SH10 hydrogenerator line can be supplied with the following...

www.weg.net SH10 line In order to minimize the problems caused by shaft deflection and to reduce eventual additional costs, the SH10 line was designed to operate with maximum deflection of 0.40 mm, with the exception of the Pelton type turbines that typically show higher deflection values. Axial loads N - Without axial loads S - Low axial loads M - Medium axial loads L - High axial loads X - Upon request Frame Example: 11E24SKM Figure 1 - Axial loads Efficiency The current need for a better use of energetic resources led WEG to develop new designs and manufacturing methods that resulted in...
