More Information
Summary:The present invention relates to an insulator-fixed cross-arm for adjusting the tension of overhead distribution lines, and more specifically, to an insulator-fixed cross-arm for adjusting the tension of overhead distribution lines, which is improved to prevent impacts from being delivered to an insulator or to each connection part when distribution lines are shaken, and to sufficiently buffer and adjust changed tension when the overhead distribution lines contract or expand due to temperature changes, thereby extending the lifespan of each part. According to the present invention, when the condition of a distribution line is changed due to expansion, contraction, etc., a supporting bar, which fixes the distribution line by using an anchor, horizontally rotates and lessens the changes, thereby minimizing tension applied to the distribution line and the anchor, and preventing the distribution line from being expanded and stretched by high temperatures. In addition, the present invention includes a fixing unit buffering component and therefore softens impacts, thereby preventing damage to an insulator.
