Figure 1: Connection of cables (example)
Main cables
The resilient installation of the GenSet must be con-
sidered when fixing the alternator cables.
The cables must be installed so that no forces have
any effect on the terminal box of the alternator.
A support bracket can be welded on the engine
base frame. If this solution is chosen, the flexibility in
the cables must be between the cable tray and the
support bracket.
The free cable length from the cable tray to the
attachment on the alternator must be appropriate to
compensate for the relative movements between
the GenSet and the foundation.
The following can be used as a guideline:
The fix point of the alternator cables must be as
close as possible to the centre line of the rotor.
Bending of the cables must follow the recommen-
dations of the cable supplier regarding minimum
bending radius for movable cables.
If questions arise concerning the above, please do
not hesitate to contact MAN Diesel & Turbo.
Note: The responsibility for alternator cable installa-
tion lies with the Installation Contractor. The Installa-
tion Contractor has to define the dimension of the
cables with due respect to heat conditions at site,
cable routing (nearby cables), number of single
wires per phase, cable material and cable type.
