Distribution Transformer

Additional Details

Standards:

Our transformers: Manufactured and tested as per IS: 2026, IS: 1180, IEC 60076Winding design and insulation to tolerate thermal and short circuit stressesOverload capacity maintained as per IS: 6600 and specific requirements

Core:

Superior quality examination of diverse grades and designed according to Customer’s No Load Loss specification

On-Load Tap Changer

Transformer’s fitted with OLTC with different tapings on HV windings to suit client requirement or grid voltage conditions at customers siteFor automatic voltage monitoring, OLTC is supplied with remote Tap Changing Cubicle (RTCC) Panel and Automatic Voltage Regulator (AVR) (optional)

Winding:

Copper used for winding Spiral low voltage winding with paper insulated rectangular conductorsCrossover HV coils with paper cover & SE copper wire Disc winding with rectangular copper strips (some cases multiple Disc)

Tank:

To withstand temperature rise rigid type of transformer tank with attached cooling fins is required for extensive cooling area.Corrugated type transformer tank for better cooling and space economy

Oil:

Oil, conforming to IS: 60296, is filled in through streamline filter for moisture and gas removalThe windings are warmed in a hot air chamber to get high IR values
