<strong>Synchronous</strong> <strong>Generators</strong> <strong>BG</strong> <strong>132</strong> / <strong>BG</strong> <strong>160</strong><br />
Chapter 2, Description<br />
2.5 Mechanical designs<br />
Depending on the rated power output <strong>and</strong> the number of poles the generators<br />
are produced in two different sizes: <strong>BG</strong> <strong>132</strong> or <strong>BG</strong> <strong>160</strong>.<br />
Size <strong>BG</strong> <strong>132</strong> is used for 2-pole generators with rated power outputs up to 17<br />
kVA. These generators are available as brushless type or with carbon brushes.<br />
Depending on the kind of use, generators of the size <strong>BG</strong> <strong>132</strong> can either be built<br />
as single-bearing generators or as two-bearing generators. Single-bearing<br />
generators are directly mounted to the engine. In this case the engine bearing is<br />
used as second bearing.<br />
Size <strong>BG</strong> <strong>160</strong> is used for<br />
• 2-pole generators with rated power outputs starting from 20 kVA or for<br />
• 4-pole generators with rated power outputs starting from 10 kVA.<br />
<strong>Generators</strong> of the size <strong>BG</strong> <strong>160</strong> are exclusively available as brushless generators<br />
<strong>and</strong> are only produced as two-bearing generators.<br />
Two-bearing generators are usually installed right next to the engine. Regarding<br />
the generator drive, there are various options to choose from (refer to section<br />
2.6 on page 21).<br />
To cover a wide range of applications, the generators can be delivered in<br />
different versions regarding the electrical connection.<br />
• Generator with terminal box mounted (st<strong>and</strong>ard type):<br />
The terminal box mounted on the generator contains a connection terminal<br />
plate for the connecting cables as well as the generator governor.<br />
Furthermore, a suppression filter can be installed in the terminal box.<br />
However, the suppression filter can also be located in an external control<br />
cabinet, if desired. Further information about the terminal box can be found<br />
in section 2.7 on page 22.<br />
• Cable directly lead out of the generator in a hose without a terminal box<br />
mounted:<br />
For this version, all connecting cables of the generator as well as the cables<br />
for the generator governor are led out of the generator housing using a hose.<br />
This version offers the special advantage, that the generator can also be used<br />
in relatively hot environments. In this case, the generator governor as well as<br />
the complete current distribution <strong>and</strong> the electrical fuse protection has to be<br />
installed in an external control cabinet.<br />
