Product Information
According to the use can be divided into: straight cross arm; Angle arm; Tensile cross arm.
According to the material can be divided into: iron cross arm; Porcelain cross arm; Synthetic insulated cross arm.
Power parts are installed on poles or towers to support the main components of transmission cables. It mainly includes electrical cross arm, pole hoop, electrical support and transformer fence.
According to the requirements of the customer's drawings, it is made of special steel by cutting, welding, piercing, bending and other processes. After completion, it is subject to hot-dip galvanizing and anti-corrosion treatment, so that the power cross arm will not rust when used in the open air, and maintain a long service life.
Product Details
Use as follows:
Linear cross arm: only consider the vertical load and horizontal load of the wire under normal, unbroken line conditions;
Tensile cross arm: in addition to bearing the vertical and horizontal load of the wire, it will also bear the tension difference of the wire;
Angle arm: In addition to bearing the vertical and horizontal load of the wire, it will also bear a large unilateral wire tension.
According to the stress of the crossarm, single crossarm is used for the straight bar or the Angle bar below 15 degrees, while the Angle bar, tensioner bar, terminal bar and branch bar with a Angle above 15 degrees are all double crossarm. (In some areas, double cross arm is used)
The cross arm is generally installed 300mm away from the top of the rod. The straight cross arm should be installed on the receiving side, and the cross arm of the Angle rod, terminal rod and branch rod should be installed on the side of the cable

The cross arm originated from the power industry and is an important part for carrying wires on the tower. Before entering the crossarm production site, equipment inspection and tool preparation are required. The equipment includes milling machine, drilling machine and cutting machine, etc., which can be ready to proceed to the next step.
1. Cutting process
After entering the factory, the transverse arm should be cut and formed. The cutting process is the first step in the production of the transverse arm. This step requires the help of a cutter to ensure that the arm length is accurate.
2. Opening process
After cutting, holes need to be made in the cross arm to install the bolt fixation. Opening is the most important step in crossarm production and must be accurate. This process requires the use of a drill machine to operate, and both the opening position and the aperture need to be precisely mastered.
3. Turning process
Turning is an important step in the production of crossarm, and also the key to ensure the smooth surface of the crossarm. This process requires the use of milling machines to operate, and the process requirements for the cross arm surface are extremely high and require strict control.
4. Pickling process
After the turning is completed, a pickling process is required to remove rust and impurities from the cross arm surface. This step requires the help of pickling tank and cleaning equipment, the concentration of pickling liquid and pickling time need to be strictly controlled to ensure that the pickling effect is good.
5. Painting process
The last step before the end of production is painting. Spray paint can make the surface of the arm more smooth, with better corrosion resistance. This process requires the use of a special paint machine to operate, and both color and finish uniformity need to be controlled.
The function of the transverse arm
1 Bearing Function
One of the most basic functions of the crossarm is load-bearing. It can be used to support objects and thus maintain their stability.
Crossarms are commonly used in construction sites, warehouses and freight vehicles. With the use of crossarms, heavy weights can
Smooth handling, storage and transportation, reducing the risk of vibration and damage during the force process.
2 Balance and stability functions
The arm also provides balance and stability. When the object needs to be placed on an uneven surface or
When you need to cross a gap, you can use the cross arm to achieve balance and ensure the stability of the object. Cross arm transfer
It can be used as a frame to support objects, keeping them balanced and preventing toppling.
3 Transport and suspension functions
The crossarm also plays an important role in the transportation process. For example, on construction sites, cross arms are used for construction scaffolding provides a stable working platform for workers. In addition, the cross arm can also be used to hang objects, such as lights tools, wires and curtains. This function makes it a stage setting, interior decoration and outdoor installation an important part of the occasion.
4 Power transmission function
It can also be used to transmit force and power. In the field of mechanical engineering, the crossarm can be used as a transmission device part, which transfers power from one part to another. This mode of transmission is usually used for transfer back to transfer dynamic or linear motion, and plays an important role in the operation of mechanical equipment.
5 Beautification and decoration functions
In addition to its functional role, crossarms are often used for beautification and decoration. In the field of interior design and architecture, the arm can be used to divide Spaces, provide artistic effects and add visual layers. Material, shape and face of the crossarm colors can be selected as needed to suit different decorative styles and design needs.
