摘   要：在我国混凝土电杆行业整体朝着绿色低碳、高质量方向发展的趋势下，GB/T 4623—2014《环形混凝土电杆》中的部分技术条款已滞后于行业发展现状，难以适配当前生产与应用需求，亟需对其进行修订，以推动电力行业高质量发展。GB/T 4623—2025《环形混凝土电杆》基于我国环形混凝土电杆的实际生产和使用现状，参考国外相关行业的先进生产技术，并考虑行业的绿色低碳、高性能、自动化、国际化等需求，对GB/T 4623—2014《环形混凝土电杆》进行了修订，为便于该标准的使用方准确理解标准条款的具体含义，正确贯彻实施标准的具体要求和规定，本文介绍了标准的修订背景和意义，并对标准的主要条款进行了解读。新版标准已于2025年10月31日发布，2026年5月1日实施。新版标准发布实施后，将有效提升混凝土电杆的产品质量与使用性能，拓宽产品应用领域与市场空间，助力企业绿色健康可持续发展，推动行业产品国际化发展与对外合作。Abstract: Against the backdrop of China’s concrete pole industry generally moving towards a green, low-carbon, and high-quality development direction, certain technical provisions in GB/T 4623—2014 Circular concrete pole have lagged behind the current state of industry development, making them difficult to adapt to existing production and application needs. There is an urgent need to revise the standard to promote the high-quality development of the power industry. The edition of GB/T 4623—2025 Circular concrete pole is based on the actual production and usage status of circular concrete poles in China, with reference to advanced production technologies from related foreign industries, and taking into account the industry’s needs for green and low-carbon solutions, high performance, automation, and internationalization. To facilitate accurate understanding of the specific meanings of the standard’s provisions by its users and to ensure proper implementation of its requirements and regulations, the background and significance of the revision were introduced, and an interpretation of key provisions of the standard was provided. The new edition was issued on October 31, 2025, and will be implemented on May 1, 2026. Following the issuance and implementation of the new edition, it will effectively enhance the product quality and service performance of concrete poles, broaden their application fields and market space, support the green and sustainable development of enterprises, and promote the internationalization of industry products and foreign cooperation.
