Why is wired transmission superior for the power grid?

2025-08-16

For the bulk power transmission that our company supports, wired infrastructure is the only practical solution due to its overwhelming advantages in three key areas:

  • Efficiency: Wired transmission is exceptionally efficient, with modern UHV (Ultra-High Voltage) lines losing as little as 2-3% of the power over thousands of kilometers. In contrast, even the most advanced long-distance wireless transmission methods currently lose more than 50% of the energy, making them economically unfeasible for powering cities and industries.

  • Safety and Control: A wired network provides a contained and controllable path for electricity, ensuring it is delivered to specific, intended locations. Wireless transmission, especially over long distances, would broadcast energy into the environment, raising significant safety concerns for both humans and wildlife.

  • Reliability: The stability and reliability of a wired grid are well-established. It is a robust system that can be precisely managed and maintained. The entire process, from production to delivery, is measured and controlled, which is crucial for the stable operation of a nation's power supply.

Ultimately, while wireless electricity has a future for small-scale applications, the physics and economics of large-scale power delivery make overhead and underground wired systems the only reliable solution for the foreseeable future. This is why our products—like hydraulic pullers, OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners, and OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks—remain essential for building and maintaining the grid.
