我国牵头制定电力腐蚀国际标准，现存电线电缆相关企业超107万家

<article><section data-type="rtext"><p>【环球网科技综合报道】近日，由我国牵头制定的国际标准《金属和合金的腐蚀 交流电条件下导体材料腐蚀测试方法》（ISO TR 22801:2026）经国际标准化组织正式发布。全球输配电线路总长已超8000万千米，铜、铝等导体材料广泛用于导线、金具等关键部件，而腐蚀已成为制约其服役寿命、威胁电网安全运行的关键因素。该标准的发布标志着我国在电力导体腐蚀测试领域的技术能力获得国际广泛认可。</p><p>标准规定了电源设备类型、输出功率等7项关键指标，模拟50或60赫兹频率下输电导线表面电磁场分布，实现贴近实际工况的腐蚀动力学与速率测试。以3毫米铝圆柱样品通入40安培交流电为例，其腐蚀速率可达无电流条件下的3倍，精准还原了交变电流、电磁场与腐蚀介质的耦合加速效应。</p>

<p>该标准将支撑新材料、智能电网输配电等战略性新兴产业发展，通过精准预判腐蚀规律，为差异化防腐与服役寿命评估提供技术支撑，预计可降低电网运维成本10%以上。</p><p>天眼查专业版数据显示，截至目前我国现存在业、存续状态的电线电缆相关企业超107.9万家。从区域分布来看，江苏省、山东省、上海市电线电缆相关企业数量位居前列，分别拥有超12万家、11万家和8.1万家。排在其后的是河北省和广东省。（赵华）</p><p><i
