Product Description

Prime Mover : Single/Double cylinder, Air/Water cooled, vertical, four stroke, constant speed, stationary, compression ignition, handle/push start diesel engines form the driving power for the A. C. Generators. 

A.C. Generators : A. C. Generators are self-excited and self regulated in screen protected drip-proof enclosure. These A. C. Generators are available in single phase and three phase at ***0 R.P.M. These A.C. Generators are manufactured as per Indian Standard Specifications ****4 (part 1) under strict quality control capable of sustaining *0% over load for one hour in any twelve hours normal running. 

Armature : The armature cores are of high quality Silicon steel stampings to ensure minimum energy losses. The armature core is rigidly keyed to a sturdy shaft and clamped with heavy end-ring. 

Body & Ventilation : The stator frame consists of thick sheet steel which is rounded and machined for its alignment with endshields. The endshield are of cast iron with easy ventilation windows on both sides. A balanced and efficient aluminum fan is fitted with the armature spindle which gives uniform cooling and long life to the windings. The whole body is based on steel plates to ensure stability. 

Winding & Insulation : Both D.C. and A.C. windings are of super synthetic enameled copper wire of high conductivity. High grade insulating materials are used in winding the field coils and armature which are then varnished and thoroughly dried. Winding is of class ``A'' insulation. Voltage regulation is within ± 5 %.

Slip-ring assembly : The slip-rings are made of specially designed gun metal alloy of homogeneous texture set in phenolic resinous power to facilitate spark-free and no energy loss conduction. Brush holders are fitted with insulated bolts. Positive collection of current is ensured by copper bush flexible and adequate connecting leads.
