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.

 

Phone interference

THF(defined by 40th part of BS4999) <2%.TIF(defined by ASAC50.12)<50

Radio interference

Brushless apparatus and quality AVR ensure little radio interference in transmission. RFI noise filter is also available.
