\u2014\u2014A newly installed 20-kilometer optical cable now provides an “anti-icing layer” for the 750-kilovolt\u00a0Nacheng Line<\/p>\n
URUMQI, China<\/span><\/span>, Aug. 29, 2025<\/span><\/span> \/PRNewswire\/ — On August 28<\/span>, as the Optical Time Domain Reflectometer (OTDR) curve of the final fiber core stabilized at zero, State Grid\u00a0Xinjiang Information & Communication Company, in cooperation with Xinjiang Power Transmission and Transformation Limited Company, successfully completed the ice damage mitigation project for the 20-kilometer OPGW optical cable on the first and second circuits of the 750-kilovolt Kanas to Tacheng Substation line. Throughout the renovation, all communication-related production control services remained uninterrupted, with no alarms triggered, thereby enhancing grid reliability for the high-load winter and spring seasons.<\/p>\n On December 7, 2024<\/span>, the\u00a0Nacheng Line experienced a trip due to ice-induced conductor jump, which temporarily disrupted the transmission of renewable energy from Altay Prefecture. The remediation project utilized the end-of-summer maintenance window to remove the existing optical cables from two ice-prone sections 199#\u2013241#<\/span>\u2014and replace them with 20 kilometers of new\u00a0OPGW optical cables mounted on dedicated poles. This significantly improved the line’s resistance to ice accumulation. The construction spanned multiple “three-crossing” zones, including the “Kua” Expressway and the 220-kilovolt Nafeng Line, resulting in a total optical cable interruption of 10 days. Prior to the operation, the communications team adopted a three-tier planning process\u2014team drafting, professional review, and leadership approval\u2014to develop a comprehensive “Major Maintenance Plan.” During the renovation, a “primary maintenance and secondary backup” strategy was implemented, with phased planning for optical path detours and critical service channel transitions. On-site OTDR tests were conducted three times, confirming consistent core attenuation and bit error rate before and after the operation, ensuring that all production control services remained “zero-perceived.”<\/p>\n Young technician\u00a0Abudukeyumu stated, “This optical cable renovation presented high technical complexity and broad operational impact. We strictly followed standardized operation procedures and completed the task two hours ahead of schedule.”<\/p>\n Looking ahead, the company will institutionalize the experience gained from the “dual-line mutual backup and rotational treatment” approach, develop standardized operation guidelines, and continue implementing “zero-perception” governance for similar ice-related risks, thereby fully supporting the digital and intelligent operation of the\u00a0Xinjiang power grid.<\/p>","protected":false},"excerpt":{"rendered":" <\/p>\n \u2014\u2014A newly installed 20-kilometer optical cable now provides an “anti-icing layer” for the 750-kilovolt\u00a0Nacheng Line<\/p>\n URUMQI, China<\/span><\/span>, Aug. 29, 2025<\/span><\/span> \/PRNewswire\/ — On August 28<\/span>, as the Optical Time Domain Reflectometer (OTDR) curve of the final fiber core stabilized at zero, State Grid\u00a0Xinjiang Information & Communication Company, in cooperation with Xinjiang Power Transmission and Transformation Limited Company, successfully completed the ice damage mitigation project for the 20-kilometer OPGW optical cable on the first and second circuits of the 750-kilovolt Kanas to Tacheng Substation line.
