Product Details  Daewoo engine diesel generator set 1.engine from cummins DEUTZ, DAEWOO, chinese engine ,sound proof frame, 8-1200kw.  Daewoo engine diesel generator set  Features: 1) Excite system providing invariable excitation on all occasions.  2)Easy to be connected with power network or other generators..  3)Balanced rotor with single or two sealed ball bearings  4)Convenient installation and maintenance with easy access to terminals, rotating diodes and coupling bolts  5)Wide range of Flange adaptor and single bearing coupling disc  Meet leading standards MECHANIC FEATURES Frame All industrial standard is IP21,also IP23 is an option, but rates power will decease 5% Marine standard alternator is IP23,Air filter is an option, but rated power of the alternator will decrease 5% while it is installed. Shaft and Key All of alternator rotors should pass balance test, whose vibrations are lower than the minimum of BS6861 P.1,G 2.5 two bearing alternator has a half-key testing balance Terminal and terminal box The three-field alternator had 12 leads brought out to the terminals in the terminal box. The terminals are put on the non drive end . The box is equipped with removable panels. Voltage regulation  Voltage regulation refers to the change of voltage from no-load to full-load with power factor ranging from 0.8 to 1 and 3%s fluctuation of the speed of engine. Voltage is adjusted via potentiometer of AVR  ELECTRIC FEATURES INSULATION Insulation Class H All regulatory components are made up with special materials and are immersed in lacquer by VPI. Vanish and colophony materials are develop to strengthen the processing and machinery intensity of windings and revolving parts for protecting the alternator work under corrosive environment. Winding and electric features: A continuous damp windings abates surges. ] Phone interference THF(defined by 40th part of BS4999)
