Description
技术领域 technical field
本发明涉及绝缘子领域，更具体地说涉及一种免扎线绝缘子。 The invention relates to the field of insulators, in particular to a wire-free insulator.
背景技术 Background technique
目前，一般将导线固定在针式复合绝缘子、支柱复合绝缘子上的方式有两种：一是采用单股金属线将导线绑扎在绝缘子的线槽中，绑扎前要先将金属线缠绕成圆盘状。优点是费用低，缺点是导线固定的牢固程度取决于绑扎者的责任心和技术水平。二是采用螺栓将导线固定在绝缘子顶部。优点是美观，缺点是缺少伸缩余地，导线张力变化时容易损伤绝缘子。另外，上述两种导线固定方式还存在两个显著缺点：费时、费力，固定一根导线需耗时3～10分钟。 At present, there are generally two ways to fix wires on pin composite insulators and post composite insulators: one is to use single-strand metal wires to bind the wires in the slots of the insulators, and the metal wires must be wound into discs before binding shape. The advantage is that the cost is low, and the disadvantage is that the firmness of wire fixing depends on the responsibility and technical level of the binder. The second is to use bolts to fix the wires on the top of the insulator. The advantage is that it is beautiful, but the disadvantage is that there is no room for expansion and contraction, and the insulator is easy to be damaged when the tension of the wire changes. In addition, there are two significant disadvantages in the above two wire fixing methods: time-consuming and labor-intensive, and it takes 3 to 10 minutes to fix a wire.
