支架采用环氧树脂复合材料制成的方管,保证绝缘性能。 The bracket adopts a square tube made of epoxy resin composite material to ensure insulation performance.
本发明的使用过程: The use process of the present invention:
将预安装的导线拴在吊钩上,拉动绳索,使吊钩吊起到设定高度,进行带电安装导线。根据横担的长度,通过拔起和下落中心杆,使支架与电杆的夹角增大或缩小,从而改变两相距支架之间的距离,实现适应横担长度的要求。 Tie the pre-installed wires to the hook, pull the rope to lift the hook to the set height, and install the wires live. According to the length of the cross arm, the angle between the bracket and the pole is increased or decreased by pulling up and down the center pole, thereby changing the distance between the two supports to meet the requirements of the length of the cross arm.
横担用于拉起导线。通过松紧拉绳的长度和吊钩滑轮上部的绳索长度,能够使悬空导线达到设定高度。 The cross arm is used to pull up the wire. By the length of the elastic stay rope and the length of the rope on the upper part of the hook pulley, the suspended conductor can reach the set height.
利用已有的绝缘横担将其组合成三角形把导线吊起,通过力学的特性使导线的垂直荷重进行分解,再通过紧线使导线上、下缩放。能够使导线的垂直距离达到适当作业高度。 Use the existing insulating cross-arms to combine them into triangles to lift the wires, decompose the vertical load of the wires through the mechanical characteristics, and then make the wires scale up and down by tightening the wires. It can make the vertical distance of the wire reach the proper working height.
把中项导线的支点底端固定在抱紧电杆的抱箍上,用顶丝锁紧抱箍,防止绝缘横担摇摆。 Fix the bottom end of the fulcrum of the middle conductor on the hoop that holds the pole tightly, and lock the hoop with the top wire to prevent the insulating cross arm from swinging.

1、工频耐压45KV,1分钟内无击穿现象。 1. The power frequency withstand voltage is 45KV, and there is no breakdown phenomenon within 1 minute.
2、机械强度和拉伸强度达到规范技术指标。 2. The mechanical strength and tensile strength meet the standard technical indicators.
3、绝缘性能达到规范技术指标。 3. The insulation performance reaches the standard technical index.
4、能够带电状态下更换导线。 4. The wire can be replaced under the charged state.
本发明能够带电更换导线时,将原有的横担承载导线的垂直荷重转移到绝缘横担上来,保证导线稳固可靠。并且可利用绝缘横担装置上的升降将三相导线的高度不同程度的提升或降低。能够有效的控制导线与横担及同杆并架的其它线路的空气间隙和安全距离,具有安装方便、操作简单、多层导线都能够通用的特点。克服了所有直线杆更换横担的困难。 The invention can transfer the vertical load of the original cross arm carrying the wire to the insulating cross arm when the wire is replaced with electricity, so as to ensure the stability and reliability of the wire. And the height of the three-phase conductors can be raised or lowered to varying degrees by using the lifting on the insulating cross-arm device. It can effectively control the air gap and safety distance between the conductor and the cross-arm and other lines paralleled on the same pole.
