ELECTRICAL CHARACTER:

The standard AVR include Sx440, SX460、 KRS440B、 MX341B OR MX321 (optional AVR) 
The main stator provides the exciter stator with the power via AVR. The high efficiency semiconductor inside AVR ensures the output voltage gradually up to the rated value from the initial lower remanence voltage. The power of the exciters rotor is output to the host rotor through 3-phasefullwave rectifier. Two ends of the rectifier are connected with piezo resistance for restraining surge voltage and avoiding the impact caused by short circuit of parallel synchronization loss. Exciters stator is equipped with permanent magnetic steel can make generator starting smoothly in any occasions. Whole stable voltage regulation is 1%, and SX440, KRS440B、 MX341B、 MX321 have features of parallel connection. Low frequency protection and exterior voltage adjustment, etc. 
MX341B and MX321 are the AVR for the permanent magnetic motors. 

VOLTAGE REGULATION: 

Voltage regulation refers to the change of voltage from non-load to full-load with power factor langing from 0.8 to 1 and 4%'s fuctuation of the speed of engine. Voltage is adjusted via potention meter of AVR.

ELECTRIC FEATURES:

INSULATION:

Insulation class H

All regulatory components are made up with special materials and also immersed in lacquer by peculiar tech. Varnish and colophony materials are developed to strengthen the processing and machinery intensity of windings and revoving parts for protecting the generator work under corrosive environment.

WINDINGS AND ELECTRIC FEATURES:

All the generator stators adopt high magnetic conductibility energy cold rolling silicon steel plate to fold up, double winding,firm structure, good insulating.Continuous damp windings abate surges. T'he poles and teeth of the windings are carefully chosen, which helps checking the wave distortion of output voltage. 

PHONE INTERFERENCE:

THF (as defined by BS EN 600 34-1) <2%.TIF (as defined by NEMA MG1-22) <50.

RADIO INTERFERENCE:

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

MECHANIC FEATURES:

FRAME:

All the industrial generator's standard is IP22 (GB/T 4942.1, IEC 60034-5) .IP23 is also available, but rated power will decrease 5%.Marinegenerator is IP23 as normal standard. Air filter is an option, but rated power will decrease 5% while it is installed. 

AXIS AND KEY:

All rotors should pass balance test, which vibration is lower than the minimum value of BS6861 P.1,G2.5.Two-bearing generator has a half-key testing balance. 

TERMINAL AND TERMINAL BOX: 

The normal three-phase generators have 12 leads brought out to the terminals in the terminal box.The terminals are put on the board of the non-drive end. AVR is mounted in the terminal box made in steel sheet and enough space left inside for laying wires. The box is equipped with removable panels. 

ENGINE ADAPTOR AND COUPLING:

TwG series generators have two kinds of structure, single bearing and double bearing. 
Engine adapler for single-beaing could be SAE00、0、 12、 1, 2、3、 4 and 5, Couping disc for single-beaing could be SAE#6.5, 7.5, 8.10,,11.5, 14, 16, 18and 21. 
Engine adapter for double-bearing could be SAE#00, 0, 1/2, 1, 2, 3, 4 and 5.

OPTION FEATURES:

1.Adapters and interchangeable drive disk 
2.Single phase 
3.Remote voltage adjust 
4.IP23 protection class 
5.Space heaters 
6.Thermistors 
7.Circuit breaker
