-          Wide range of Flange adaptor and single bearing coupling disc

-          50HZ/ 60Hz, 1500RPM/ 1500RPM as standard,5kw~1250kw

-          Certificate: CE/ISO9001

2. Electrical Character:

Excitation system: The main stator supplies power to exciter stator via Automatic Voltage Regulator (AVR).The output of exciter rotor is fed to the main rotor through a three phase full wave rectifier. There are varistors at the both ends of the rectifier for restraining surge voltage and avoiding the impact caused by short circuit or parallel synchronization loss. Exciter stator is equipped with permanent magnetic steel in order to start up the alternator smoothly in any occasion.

3. Insulation & Immersion:

Insulation class H.  

All wound components are made up of specialized material and immersed in varnish by especially technology. Resin matrix material is developed to strengthen the process and machinery intensity of windings and revolving parts for the alternator working under harsh environment.

4. Windings and electric features:

Standard 2/3 pitch windings design can eliminate the triple frequency harmonics on the voltage waveform which is the optimum design for the trouble-free supply of nonlinear loads.

5. Physical features:

 Shaft & key

All generator rotors are dynamically balanced to better than BS6861: Part 1 Grade 2.5 for minimum vibration in operation. Two bearing generators are balanced with a half key.

6.Wiring terminal and terminal box

Standard alternator is 3 phase re-connectable to 12 ends brought out to the terminals, which are mounted on a cover at the non-drive end of the alternator.A sheet steel terminal box contains the AVR and provides ample space for customer's wiring and gland arrangements. It has removable panel easy access.
