摘要
针对1 000 kV特高压带电作业用绝缘硬拉棒(简称硬拉棒)存在的整件长、重量大,不利于运输保管与操作的缺点,通过对新型高性能纤维的研究和改性处理,并与热塑性材料复合成型,研制出绝缘软拉棒。该绝缘软拉棒重量仅为同规格硬拉棒的34.6%,其端部接头重量仅为原钢接头的1/10,而比强度提高了2.85倍,且可盘圈运输与保管,解决了原来长件难以运输和保管问题。绝缘软拉棒是超高压、特高压带电作业用绝缘硬拉棒的升级换代的产品,具有"安全可靠、运输方便、轻便灵活"的特点。
Hard insulating rod （＂hard rod＂ for short） for live working with ultra-high voltage of 1000 kV has the disadvantages of being too long and very heavy, which may cause many troubles in transportation, storage and operation. Therefore, flexible insulating rods were dew-loped through improving the high-performance fibers and the compositively molding of the fiber with thermoplastic material. This new kind of rods can only he of 34.6% weight of hard rod with the same standard. Ahhough the joint of a flexible insulating rod can only be of 10% weighl of the steel joint, the specific strength increases to 2.85 times. With resembling in coil shape, the flexihle insulating rod owereomes the difficulty of storage and inconvenience during transportation. It replaces hard insulating rod for live line working with uhra-high woltage and boosts the features of being ＂safe, reliable, light and flexible＂.
