STANDARD SPECIFICATION
CUMMINS POWERED GENERATOR SETS ¨CC
SERIES
OUTPUT POWER : 115KW ¨C 160KW
Quality Standards
Our diesel generating sets meets the following standards:
ISO8528-1993, BS4999, BS5000, BS5514, GB/T2820-1997, IEC34,
VDE0530, NEMA MG-122, GB755, CSA22-2, AS-1359.
‘‘
Factory Test
Each our generating sets must be got through 2 hours load test for
running 0%, 25%, 50%, 75%, 100% and 110% load before dispatch, All protective
devices, control functions are simulated and it‘―s system
checked, proved and
then passed for dispatch. A test certificate can be provided upon request.
General Generating Set Features
1.
The complete generator
set is mounted, as a whole, on a heavy duty fabricated, welded steel skid base
frame;
2.
The engine and alternator
are directly coupled by means of an SAE flange so that there is no possibility
of misalignment after prolonged use. The engine flywheel is flexibly coupled to
the alternator rotor and full torsional eveluation has been carried out to
guarantee to no harmful vibration will occur in the assembly.
3.
Anti- vibration pads are
affixed between engine/alternator feet and the base frame, Thus ensuring
complete vibration isolation of the rotating assemblies and enabling the
machine to be placed on an uneven surface without any detrimental effects;
4.
Integrated GCU control
system provides multiple alarm channels to protect engine.
Diesel engine ¨C
CUMMINS
The
Cummins B serial engine is from the company- CUMMINS, U.S.A.,
now made in joint venture company‘ͺ DongFeng Cummins Co., Ltd.
1.
Compact size with reasonable structure;
2.
Low fuel and oil consumption with long overhaul
service intervals, profiting customer for operation costs saving;
3.
Precise speed control with GAC electrical governor
system, speed stability band width
‘ά‘ΐ0.25%, Speed droop
(static)
‘ά1%;
4.
Convenience for
operation and maintenance,
backed by worldwide Cummins service network.
Alternator ¨C
STAMFORD
The first-class brand of generator which is on the leading status in the
world
1.
Screen protected and
drip-proof protection, self-regulating brushless alternator with fully
interconnected damper windings, and
dynamically balanced rotors with
sealed for life bearings. 12 wire re-connectable windings provide
a wide range of 3-phase voltage.
1.
The insulation system is
class H, easy
paralleling with mains or other generators, standard 2/3 pitch stator windings
avoid excessive neutral currents;
2.
Backed
by worldwide service network.

Rating Definitions (Operation at Altitude
‘ά1000m,
Ambient temperature
‘ά 40‘ζ)
Continuous Power Model SC
with no Suffix
These ratings are applicable for supplying continuous electrical
power (at variable load) in lieu of commercially purchased power. There is no
limitation to the annual hours of operation and this model can supply 10%
overload power for 1 hour in 12 hours.
Standby Power Model SC
with Suffix (S)
These ratings
are applicable for supplying continuous electrical power (at variable load)
in the event of a utility power failure. No overload is permitted on these
ratings. The alternator on this model is peak continuous rated(as defined in
ISO8528-3) at 27‘ζ.
