Answer: The amount of energy lost varies significantly by region and the quality of the electrical infrastructure. On average, the global energy loss in transmission and distribution (T&D) systems is estimated to be between 8% and 15% of the total electricity generated. In more advanced, well-maintained grids, this figure can be as low as 5-8%, while in some regions with older infrastructure, it can exceed 30%.

These losses are divided into two main categories:

• Technical Losses: These are inherent to the physics of electricity transmission. They primarily occur due to resistance in conductors (I²R losses), transformers, and other equipment.

• Non-Technical Losses: These are caused by external factors such as electricity theft, metering inaccuracies, and billing errors.

This is a critical area where high-quality equipment, such as the advanced overhead and underground cable laying equipment manufactured by Ningbo Changshi, plays a crucial role in minimizing technical losses and improving overall grid efficiency.
