Diesel Generators
Prime Mover: Single/Double Cylinder, Air/Water cooled, vertical, four stroke, constant speed, stationary, compression ignition, handle/push button start diesel engine from the driving power for the A. C. Generators.
A.C. Generators: A. C. Generators are self-excited & self regulated in screen protected drip-proof enclosure. These A. C. Generators are available in single phase and three phase at 1500 R.P.M. These A. C. Generators are manufactured as per Indian Standard Specifications : 13364 (pt.1) under strict quality control capable of sustaining 10% over load one hour in any 12 hours normal running.
Armature: The armature cores are of high quality Silicon steel stamping to ensure minimum energy losses. The armature core is rigidly keyed to a sturdy shaft & clamped with heavy end-ring.
Body & Ventilation: The stator frame consists of thick sheet steel, which is rounded and machined for its alignment with end shields. The end shield 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 than varnished and thoroughly dried. Winding is of class "A" insulation. Voltage regulation in within +,- 5%.
Slip-ring assembly: The slip-ring are made of specially designed gun metal alloy of homogenous 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.
Field: The field consists of four pole shoes built of high quality steel stamping, which are accurately spaced and mounted in the steel body.
Current Wave: Generator out-put current wave from remains substantially Sinusoidal under all conditions and frequency variation is within +, -5%.
Bearings:Heavy duty ball-bearings of high quality are fitted to support the armature spindle. The bearings are lubricated with high melting point grease, which help the A.C. Generators in smooth and noiseless running. Outer bearings are covered type to prevent dust.
Additional fixtures:A separate control panel fitted with voltmeter, Ampere meter/s, switch/es, blinker/and fuse-cut-out/s can be supplied on demand at extra cost.
