Ultra-high voltage (UHV) transmission line construction is currently in full swing across major countries around the globe. In Asia, China is leading the way with an ambitious plan to construct a comprehensive network of UHV lines that will bridge major energy production hubs with consumption areas, facilitating efficient energy transfer. Europe is also making significant strides, with countries collaborating on over 100 transmission projects, which involve the creation and expansion of 52,300 kilometers of high-voltage lines. This initiative aims to better integrate renewable energy sources into the existing power grid.
In North America, the United States has proposed several crucial projects. The "Southern Spirit" and three other interstate transmission lines are set to rejuvenate the aging power grid and meet the surging electricity demands. South America's Brazil has been actively engaged in the construction and operation of 800 kV DC transmission lines, primarily to transport abundant hydropower resources. Meanwhile, South Africa in Africa is planning to expand its transmission infrastructure to fuel economic growth.
When it comes to the choice of insulators in UHV projects, different countries and large enterprises have their preferences. In the United States, many companies favor composite insulators due to their lightweight nature and excellent anti-pollution capabilities. European enterprises like Siemens Energy also lean towards them, valuing their durability and reliable performance even in harsh environmental conditions. In China, State Grid has been a strong advocate for the application of composite insulators, given their outstanding overall performance characteristics. These preferences are based on the various advantages that composite insulators offer, such as reduced weight, enhanced anti-pollution properties, and greater durability, all of which contribute
Standards:
IEC 61109-2008; ANSI C29.12
Specifications:
Application:
The long rod composite insulator is essential for power grids. Installed along conductors in high-voltage and UHV lines, it offers two key functions. Firstly, it provides stable electrical insulation, crucial in UHV where high voltage threatens. Secondly, it gives mechanical support to handle long spans and heavy loads. This dual function ensures grid stability and continuous power supply.
Features:
● High Dependability:
Meeting the specific requirements of the power grid, it can operate stably for a long time, reducing the need for frequent maintenance and ensuring the smooth running of the power transmission.
● Special Design for Extra High Voltage Insulation:
Its structure and material selection are meticulously optimized with a focus on withstanding extra high voltages. Different from ordinary insulators, it takes into account the unique challenges of maintaining insulation under extra high voltage conditions in a power grid.
● Good Anti-Environmental Impact Ability:
Considering the possible severe environmental issues in different regions, it has effective designs to mitigate these impacts and ensure the normal operation of the power grid.
● Strong Adaptability to Different Conditions:
With excellent performance in dealing with various external forces and environmental changes, it can maintain its insulation and support functions for the conductors under a wide range of operating conditions.
