Dry Type Transformers

    • Dry Type Cast Resin Transformers Upto 10 MVA, 36 KV Class

    TMC India manufactures VPI & cast resin transformers designed to meet customer specifications and various national and international standards. The range includes distribution & medium power transformers up to 10 MVA, 36 kV class with class F (or) Class H temperature class of insulation. The design and process followed in TMC ensures very low level of partial discharges.

    TMC India is the only manufacturer in India to conduct E2-C2-F1 test on transformer as per IEC 60076-11 issued in 2018.

    Special Features:
    • E2 C2 F1 certification
    • Foil winding in Low voltage and High voltage windings
    • Copper / Aluminum windings as specified
    • High permeability core laminations with step-lap construction
    • Losses as per latest issue of ECBC 2017
    • Enclosure protection class upto IP44
    • Transformers with OLTC upto 36 KV class

    Advantages Of Cast Resin Transformers:

    • Highly resistant to fire and self-extinguishable
    • Non-toxicity of combustion gases in case of fire
    • can be used in highly humid and polluted environments
    • Non hygroscopic insulation provide longer life expectancy
    • Not required to wait long periods to load transformer
    • Not required to provide special arrangement for fire barriers & oil catchment etc.
    • Low installation costs
    • No maintenance required compared to oil filled transformers
    • Low losses of the operation , thanks to the possibility of installing transformers in proximity of the load
    • High resistance to short circuit stress
    • High resistance to over voltage
    • High insulation degree and no partial discharges

    Application Areas:

    • Power Distribution
    • Converter/Inverter applications
    • Renewable energy (Wind & Solar)
    • Traction applications
    • Oil & Gas Offshore platform
    • Industrial cranes
    • Seismic Conditions
