Advantages of Aluminum Alloy Conductive Cross Arm

Aluminum alloy conductive cross arm is a new type of conductive component. It is made of hot extruded aluminum alloy profiles to replace traditional copper-steel composite plates, aluminum alloy plates, etc. It has the following characteristics: light overall weight, beautiful appearance, no welding, high strength, corrosion resistance, short manufacturing cycle, high cost performance, etc.

Advantages of Aluminum Alloy Conductive Cross Arm

The main advantages of all-aluminum alloy electrode arm are no rust, corrosion resistance, and light weight. It is about 40% lighter than the traditional all-steel electrode cross arm, which makes the electrode lifting and lowering adjustment response faster and more sensitive. In addition, thicker electrodes can be used to increase the secondary current, and the total weight of the furnace is reduced, and the electrical efficiency is improved.

Due to the reduction of impedance value, the active power increases, and the input power also increases accordingly. According to statistics, the input power increases by 9%, the power factor increases, it increases the average power factor of the furnace by 4%, and the smelting cycle is shortened by 3.5%. Stable operation during use.

Due to the reduction of vibration during the heating process, the electrode consumption can be reduced by 4%. It fully meets the needs of the resonant frequency. This new all-aluminum conductive cross arm has just entered the practical stage at home and abroad. It can be said that it is the most advanced equipment in the ladle refining furnace.

The all-aluminum alloy electrode cross arm adopts a box-type structure, which is not easy to deform, has a solid structure, a simple appearance, reliable use, and easy maintenance. It is optimized in terms of the mechanical structure of the furnace body. In addition, from an electrical point of view, the resistance and reactance values are much smaller than those of the traditional old-style electrode cross arm.

In addition, the aluminum alloy electrode arm not only combines the two functions of conducting and supporting electrodes, but also simplifies the cross arm structure. After adopting this design, the cross arm conducts electricity as a whole, greatly increasing its conductive cross-sectional area. Since the aluminum alloy electrode cross arm has no insulating plate isolation at the electrode chuck part, it will not cause arcing due to the accumulation of charged dust in this part, and damage the electrode chuck.

The all-aluminum alloy electrode cross arm has certain advantages in manufacturing cost because it does not use copper.

Due to the complex on-site working environment, in order to prevent the electrode cross arms from being corroded by cooling water for a long time, magnesium alloy composite materials are also needed for electrochemical corrosion protection, and the corrosion protection cycle is about 5 years. Under normal cooling and anti-corrosion conditions, the design life of the aluminum alloy electrode arm can reach more than 10 years.
