How are transmission losses minimized?

2025-08-16

Minimizing losses is a key objective for all power line projects. The most effective strategies include:

  • High-Voltage Transmission: This is the most critical method. By stepping up the voltage, the current can be dramatically reduced for the same amount of power. For example, doubling the voltage cuts the current in half, which reduces the I2R loss by a factor of four.

  • Proper Conductor Selection: Using high-conductivity materials like aluminum and employing composite conductors like ACSR (Aluminum Conductor Steel Reinforced) and HTLS (High-Temperature Low-Sag) helps reduce resistance and thermal losses.

  • High-Quality Installation: The mechanical quality of the installation is crucial. A smooth, professional installation using proper tension stringing equipment prevents conductor damage, kinks, or abrasions that can increase resistance and lead to localized hot spots and premature failure.
