The function of the cross arm: The cross arm is an important part of the tower. Its function is to install insulators and fittings to support the wires and lightning conductors and keep them at a certain safe distance according to regulations.
按用途可分为：直线横担；转角横担；耐张横担。按材料可分为：铁横担；瓷横担；合成绝缘横担。直线横担：只考虑在正常未断线情况下，承受导线的垂直荷重和水平荷重；耐张横担：承受导线垂直和水平荷重外，还将承受导线的拉力差；转角横担：除承受导线的垂直和水平荷重外，还将承受较大的单侧导线拉力。根据横担的受力情况，对直线杆或15以下的转角杆采用单横担，而转角在15度以上的转角杆、耐张杆、终端杆、分支杆皆采用双横担。横担一般安装在距杆顶300mm处，直线横担应装在受电侧，转角杆、终端杆、分支杆的横担应装在拉线侧。 According to the purpose, it can be divided into: straight cross arm; corner cross arm; tension cross arm. According to the material, it can be divided into: iron cross arm; porcelain cross arm; synthetic insulating cross arm. Straight line cross arm: only consider the vertical load and horizontal load of the wire under normal unbroken conditions; tension cross arm: bear the vertical and horizontal load of the wire, and also bear the tension difference of the wire; corner cross arm: in addition to bearing In addition to the vertical and horizontal loads of the wire, it will also bear a large unilateral wire tension. According to the force of the cross-arm, a single cross-arm is used for straight rods or corner rods below 15 degrees, and double cross-arms are used for corner rods, tension rods, terminal rods, and branch rods with a corner angle of more than 15 degrees. The cross arm is generally installed at a distance of 300mm from the top of the pole, the straight cross arm should be installed on the power receiving side, and the cross arm of the corner pole, terminal pole and branch pole should be installed on the side of the cable.
目前现有的输电杆塔用横担结构强度不高，使用时安装不方便，电缆安装在上面容易出现受力过大而断裂的现象。 At present, the structural strength of the existing cross arm for transmission tower is not high, and it is inconvenient to install during use, and the phenomenon that the cable is easily broken due to excessive force when installed on it.
