September 15–21, 2025 marks China’s National Cybersecurity Awareness Week. This year’s theme is “Cybersecurity for the People, Cybersecurity by the People”—safeguarding high-quality development with high-level security.

At the opening ceremony, Zhuang Rongwen, Deputy Head of the Publicity Department of the CPC Central Committee and Director of the Cyberspace Administration of China (CAC), emphasized that cybersecurity concerns national security and social stability, as well as the vital interests of the people. Since the 18th National Congress of the CPC, China has thoroughly implemented General Secretary Xi Jinping’s important thought on building a cyber powerhouse, and has steadily advanced key initiatives including the security protection of critical information infrastructure, cybersecurity and data security management, and AI security governance. China has also comprehensively strengthened the cybersecurity assurance system, providing solid support for the country’s high-quality development.

Amid the wave of digitalization, cybersecurity is no longer merely a technical issue—it has become a cornerstone of national security, social stability, and public well-being. A secure, convenient, intelligent, and open network has become a new advantage for high-quality development. In critical sectors such as power, energy, and industry, cybersecurity is directly tied to reliable electricity supply for millions of households, and to the success or failure of industrial digital transformation. In scenarios such as smart substations, energy storage projects, and industrial parks, once a communication network experiences failures or security vulnerabilities, it may lead to serious risks including power outages, equipment damage, or data leakage. Therefore, building a systematic security protection framework and enhancing emergency response capabilities have become central issues for industry development.

As the construction of new-type power systems accelerates, communication networks in substations, distribution links, and energy storage projects are gradually evolving toward multi-layered and intelligent architectures:

For smart substations, both the station control layer and the process layer must ensure the reliability and security of data transmission at the same time;

Distribution sites such as switch stations and distribution rooms require stable, around-the-clock communication networks;

As digital upgrades continue, requirements for network bandwidth, resilience, and security protection are also rising.

In these real-world application scenarios, traditional communication equipment is prone to exposing shortcomings in ring-network redundancy, self-healing capabilities, wide-temperature adaptability, and security protection.

As a premium brand with 21 years of dedication to industrial Ethernet switches, Wintop Optoelectronics has long served the power sector, focusing on high-reliability communications for smart substations, distribution links, and new energy projects such as energy storage, photovoltaics, and wind power. The company offers a comprehensive domestic product portfolio of substation “Four Unifications” switch series, fully meeting diverse networking requirements across both the process layer and the station control layer of smart substations. The products have passed rigorous environmental and reliability tests—including high/low temperature, salt spray, and low air pressure—and, under EMC electromagnetic compatibility Level 4 Class A standards, have obtained full-scope qualification certifications from authoritative institutions such as the China Electric Power Research Institute (CEPRI), State Grid Electric Power Research Institute, and China Southern Power Grid Research Institute. Wintop is among the few communication equipment suppliers in the industry to hold complete qualification reports for “Four Unifications” switches.

Today, Wintop industrial switches have been widely deployed in thousands of power projects across China, covering five major links—power generation, transmission, transformation, distribution, and consumption. In multiple provinces, they have enabled stable domestic substitution for communication platforms in high-voltage substations, continuously providing solid support for the communications hubs of State Grid and China Southern Power Grid. This fully demonstrates Wintop Optoelectronics’ “hard-core strength” in the field of power communications. With outstanding performance and stability, Wintop has earned long-term trust from the power industry and has become a solid “digital defense line” for power communication networks.

National Cybersecurity Awareness Week reminds us once again: cybersecurity is not only the bottom line of national security, but also an important safeguard of people’s well-being. Wintop Optoelectronics will continue to increase investment in independent R&D, strengthen the independent and controllable nature of core technologies and products, and deliver innovative solutions, improved services, and all-around security protection to build a stable and reliable “digital defense line” for power communication networks—safeguarding the security of critical information infrastructure and supporting high-quality development of China’s power system and industrial digitalization.
