Oil Immersed Distribution Transformer

Listing ID #6192361

Kalpa offers a complete line of oil cooled three-phase distribution transformers that meet applicable IS / IEC standards. With high voltages up to 33kV and ratings up to 10 MVA, transformers are designed for outdoors covering domestic, International , commercial and industrial applications. High-grade materials, combined with sophisticated engineering design systems and state of the art test infrastructure are key elements of a transformer that will deliver years of highly reliable service.

• Design can meet any stringent specifications
• Offering low losses as per request. As per IS1180/EEL - 1, 2 & 3 BEE STAR RATING
• Capacity to Execute large volume orders.

Assured Features

• Highest dielectric insulation property to withstand Lightening Impulse
• Mechanical design to withstand short circuit forces arising during faults
• Optimum oven heating under vacuum as to achieve desired compression height and maximum insulation resistance (IR) to windings
