海底电缆结构的专利技术分析

Patent Analysis of Submarine Cable Structure

【目的】目前,海底电缆的需求量巨大,而世界上具备高压、超高压海底线缆生产能力的厂家不多,对海底电缆的具体技术分支的发展脉络和发展趋势进行分析,可为海底电缆企业提供参考。【方法】通过对海底电缆结构的专利技术进行分析,对海底电缆结构的发展进行了梳理。【结果】得出海底电缆结构全球申请趋势,海底电缆结构地域排名、中国申请趋势、中国申请人排名以及省市排名情况、海底电缆技术分支占比。【结论】通过分析发现电缆的包覆、填充、铠装都是近年来的研究重点。

[Purposes]At present,the demand for submarine cable is huge,and the number of manufacturers which has high-voltage,ultra-high-voltage submarine cable production capacity is little in the world.In order to provide advice or suggestions to submarine cable enterprises,this paper analyzes the development context and trend of the specific technical branch of submarine cable.[Methods]This paper analyzes the patent technology of submarine cable structure,and combs the development of submarine cable structure.[Findings]This paper obtains the global application trend of submarine cable structure,the regional ranking of submarine cable structure,the trend of Chinese applications,the ranking of Chinese applicants and the ranking of provinces and cities,and the proportion of technology branches related to submarine cable.[Conclusions]It is found that the cable coating,filling and armored are the keys of research in recent years.
