Core Viewpoint - Huizhou Jinlongyu Cable Industry Development Co., Ltd. has applied for a patent for a new hexagonal conductor structure in cables, which aims to enhance efficiency, reduce material usage, and lower production costs [1] Company Overview - Huizhou Jinlongyu Cable Industry Development Co., Ltd. was established in 2005 and is located in Huizhou, primarily engaged in the manufacturing of electrical machinery and equipment [1] - The company has a registered capital of 689.4183 million RMB [1] - It has made investments in one external company and participated in 254 bidding projects, holding 64 patents and 49 administrative licenses [1] Patent Details - The patent, titled "A Combination Structure of Hexagonal Conductors in Cables," was applied for on May 2025, with publication number CN120496916A [1] - The hexagonal conductors have a cross-section that is either a regular hexagon or an axis-symmetric hexagon, with equal side lengths [1] - The design allows for a tight contact between conductors without the need for a compression process, achieving a compression coefficient of over 99%, significantly reducing material usage and enhancing production efficiency [1]

◎科技日报记者 陈 曦 凌晨2点，初夏的天津街头还有一丝寒意。国网天津电缆公司电缆运检第四中心运检四班班长张华蹲在 地上一动不动，双手用力捂着定点仪的耳机，聆听城市电力"动脉"——电缆的微弱跳动。"故障点找到 了！"张华指着脚下碗口大小的地方说。这样争分夺秒排查故障的场景，对张华来说已是家常便饭。 从业27年来，张华用一身本领、一颗匠心，守护天津7600余公里电缆。他是地下2米工井里的"手术 师"，10米高空终端上的"攀登者"，更是创新工作室里的"领路人"，用汗水与智慧书写新时代产业工人 的奋斗篇章。日前，张华获评2025年全国劳动模范。 练就"绝活中的绝活" 1997年刚入行时，张华就遇到了35千伏电缆剥切难题。这项操作对力度把控要求极高，稍有不慎就会损 伤电缆绝缘层。"力度大了不行，小了也不行。"他回忆道。 为了解决这一难题，张华把退役废旧电缆绑在椅子背上，用手锯、电工刀等工具逐层剥开外护套、铠装 层、内护套、绝缘层，一练就是数月。他用了近百根废弃电缆，磨钝了十多把电工刀，最终熟练掌握了 这项操作。 有了这次经验，张华决心挑战被业内称为"绝活中的绝活"——搪铅。这种金属加工工艺通过控制喷枪火 焰，使铅锡合 ...
