ABG Cemp AC alternators are Self Excited, Self Regulated, Compact Brushless Rotating Field (BRF) type, Engineered with advanced & Innovative designs evolved from decades of National & International experience. The Generators are built with ruggedness, to ensure long lasting performance. With Innovative construction the alternators can be easily installed in confined spaces. They are built in compliance with IS 4722 / IS 13364 / BS 5000 / VDE 0530 / IEC 34. The current range from 5 to 250 kVA is suitable for industrial, Commercial, Construction, Rental, telecom, Hotel, Hospital & Service Industry for Continuous & stand by applications.
Rigid steel casing, Rotors dynamically balanced with ½ key conforms to ISO 8821 and class G2.5 ( ISO 1940 ). Square damper winding in rotor to prevent hunting & generates smooth sinusoidal wave. AC Generators are available with various choice of SAE adapters to ensure easy coupling to wider range & any brand of prime movers.
Rotor has positive locking & is mechanically stable to handle for assembly. Rotor can be removed without removing the exciter rotor/bearing from the shaft. Completely sealed, properly designed bearing assembly with increased concentricity enhances the life of the bearing. Diodes can be accessed externally making maintenance easier.
Shunt AVR is provided as a standard feature, The excitation is so effective & gives virtually a flat load curve with min. variation between no load & full load excitation voltages. This increases stability in operation. Auxiliary winding is provided on demand & with specific requirements. Excitation is suitable for maximum range* thereby providing the spare parts common to widest range & can outperform existing brands in the market. Reliable Automatic voltage regulator ABGR 43 with ± 1% regulation as a Standard feature with 4.0 amps & 90 volts D. C output.
Winding, Insulation & Impregnation
Available in standard 4/6 leads output arrangement, reconnectable output of 12 leads is optional. Dedicated single phase, 50/60 Hz versions are also available to obtain optimum performance. With 2/3rd pitch winding to eliminate 3rd harmonics, the winding is best suited for harmonic/distorted loads. Total Harmonic Distortion (THD) is less than 2% at no load. Class H double enamel coated copper wires are used. Impregnation is done with solvent less resins. Tropicalization of winding is done to prevent moisture in the windings.
Ease to assemble
Adequate space in Terminal box & accessability from both sides making it userfriendly. With adequate hand space, assembly of Single bearing machines is comfortable. This improved accessibility contributes to high level of production efficiency at OEAs. Aerodynamically designed cooling circuit also apt for acoustic enclosures, hence performance is optimized.
With wide spread service network & common spares for the widest range, services can be provided on time. Scheduled Technical training is provided in our facility / OEAs & locations easily accessible to the end users. The team with decades of technical expertise in vast product range and various brands can provide ideal solutions to maximise the performance.
- 1. Aerodynamically designed bi-directional fan for
2. Excitation system covering the widest range.
3. Diode - easy to access. can be replaced without removing bearing & excitor rotor.
4. Inside bearing cap to give positive rotor locking.
5. Unique construction. excitor stator mounted directly on the body, thereby increased concentricity and minimised vibrations.
