The term "LT Line" typically refers to "Low Tension Line." In the context of electrical engineering and power distribution, LT lines are used to distribute electricity at lower voltages compared to high tension (HT) or high voltage (HV) lines.
Here’s a bit more detail:
- **Low Tension (LT) Line:** This is used to deliver electricity to residential areas, small businesses, and industries. The voltage levels in LT lines generally range from 230V to 440V, which are suitable for everyday use in homes and small commercial establishments. LT lines are also sometimes referred to as low voltage lines in other regions.
- **High Tension (HT) or High Voltage (HV) Lines:** In contrast, these lines operate at much higher voltages and are used for transmitting electricity over long distances from power plants to distribution points. Voltage levels for HT lines can range from several kilovolts (kV) to hundreds of kilovolts.
In summary, "LT Line" stands for Low Tension Line, and it denotes the part of the electrical distribution system that deals with lower voltage levels suited for end-use applications.
