Electricity transmission is inherently not 100% efficient due to physical laws. Energy is lost as it travels through conductors, primarily because no material is a perfect conductor. The main causes of this power loss are:

• Resistive Losses (Joule heating): This is the most significant form of loss. As current flows through a power line, the conductor's resistance causes a portion of the electrical energy to be converted into heat, which dissipates into the air. This loss is proportional to the square of the current (Ploss=I2R).

• Corona Losses: On high-voltage lines, the intense electric field can ionize the air around the conductors, creating a faint, glowing discharge known as a corona. This phenomenon consumes energy and is more common in humid weather or rain.

• Leakage and Inductive/Capacitive Losses: Minor losses can also occur due to current leaking through insulators or energy being stored and released by the magnetic fields created around the AC power lines.

At Ningbo Changshi, we understand that minimizing these losses is crucial. Our overhead transmission line equipment and high-quality conductors are designed to help reduce these losses and improve overall grid efficiency.
