LT (Low Tension) Distribution Line

LT Line is the final stage of the power distribution system that supplies electricity from the Distribution Transformer (DTR) to homes, shops, offices, and industries at 415V (3-Phase) or 230V (Single-Phase).

Power Flow

33/11 kV Substation → 11 kV Feeder → Distribution Transformer → LT Panel → LT AB Cable → Energy Meter → Consumer

  1. Distribution Transformer (DTR) – Converts 11 kV to 415/230V

  2. LT Panel/MCCB – Protects the system from overload and short circuits

  3. AB Cable – Carries power safely to consumers

  4. Poles & Clamps – Support the cable network

  5. Stay Set – Provides stability to poles

  6. Earthing System – Protects people and equipment from electrical faults

  7. Lightning Arrester – Protects against lightning surges

  8. Energy Meter – Measures electricity consumption

Why LT Lines are Important?

  1. Safe power distribution

  2. Reliable electricity supply

  3. Reduced power theft with AB Cables

  4. Easy maintenance

  5. Better voltage regulation

LT distribution line is the last link between the power utility and the consumer, ensuring safe and reliable electricity reaches every home and industries.
