Professional Answer: The modern electrical grid faces several significant challenges, including the need to maintain grid stability with the integration of intermittent renewable energy sources, and the threat of severe weather events causing power outages. Other key issues include:

• Corona Discharge: At very high voltages, the electric field around conductors can ionize the air, leading to energy loss, audible noise, and even radio interference. This is why bundled conductors are often used on very high-voltage lines to disperse the electric field.

• Safety and Maintenance: The risk of accidents and the need for regular maintenance are constant concerns. The use of robust insulators, proper line clearances, and grounding is critical to preventing accidents and ensuring system reliability.

• Infrastructure Aging: Much of the world's grid infrastructure is aging and not equipped to handle increasing demand or the complexities of a modern, multi-source power system.

Our company, Ningbo Changshi, directly addresses these challenges by providing high-quality tools for both construction and maintenance. Our equipment ensures that transmission lines are installed and serviced to the highest standards, helping to mitigate the risks of corona discharge, increase system safety, and support the essential upgrades required for grid modernization. We are dedicated to providing the tools that build a safer, more reliable, and more efficient power network.
