Press Welding Foil Busbar


It is a special resource management. Due to their structure, they are resistant to maximum forces with bending and central distortions. Press welding foil bars , especially manufactured in U or S shape, can easily perform two-way movements inside the machines.

These fasteners are manufactured by welding the ends of Cu-HCP strips (foils, leaves) between 0.10 mm and 0.30 mm in thickness (foils, leaves) in order to obtain sufficient cross-section without using any additives placed on top of each other under the press to obtain the desired contact area. is done. This special welding process is performed under high pressure and heat. With press-welded flexible connectors , the resistance loss that may occur in high voltage electrical transmission is reduced to the maximum level. The contact areas can be easily coated with electrolysis or hot dipping, or they can be coated with silver in the desired micron.

Press-welded foil busbars appear as a special welding method. Foil thicknesses are produced in approximately 0.10mm-0.50mm measurements. Press welded foil busbars are durable and rigid due to their structure. They are highly resistant to bending. The manufacturing method is usually press welding. In addition, it should be especially noted that press-welded foil busbars are manufactured in U or S shape. The contact areas can be easily coated with tin, nickel or silver at the desired micron thickness at the coating stage.

Press-welded foil bars , which are both flexible and durable , are produced by going through a special welding process. In the special welding process, the leaves and foils placed on top of each other are welded directly under the press, in contact with each other, without adding any additives. Performing this welding process under heat and high pressure is one of the most important rules to be considered. Due to its durable and robust structures, it can be used easily even in high voltage areas.

Press-welded foil busbars are products with very good conductivity. They are not easily breakable like fixed blades. It has a self-cooling feature. Welded terminals Press welded foil bars can be easily cut, drilled or shaped by milling. It can be easily insulated with heat shrink tubing. Press Welded foil bars are produced from CU-ETP material.

They are easily preferred due to their durable and robust structures. It can be used in places exposed to high heat and impact. It is also preferred in very hot or very cold areas in the same way. Press welding foil bars are both durable and flexible, just like braided frexible bars. Thus, it can be used easily in harsh weather conditions and in difficult climates. The resistance of press-welded foil busbars is zero.

Generally, the conductivity properties are the same as busbars. They do not show any variable properties. It is preferred as U or S norm form in order to prevent friction situations. In addition, U-shaped press-welded foil bars move in two directions. According to the wishes and needs of the customers, the entire product is specially made with silver or tin plating in the facilities.

In this context, it should be especially noted that after all parts are completed, the process of delivering them to the customers is made. It is also specially produced in the contact areas in line with the wishes and needs of the customers. The resistors and conductors of the press-welded foil busbars are quite durable. They are known to conduct electricity quite well. In addition, it should be noted that being durable does not affect their flexibility. It is easily shaped.

Welded connection ends can be easily drilled or cut. Since the contact areas or contact points are formed without using any welding material, the contact resistance between each foil is measured to be almost zero. Press-welded foil bars are not easily breakable like fixed blades. In areas where vibration occurs (it has a self-cooling feature), the connections are at a very ideal level.

Since the molecular CU-ETP bonds of the press-welded foil busbars are quite strong, they can easily conduct electricity. Press-welded foil busbars, whose production has not been completed without undergoing a special welding process, are highly preferred especially in bus-bar systems, cells, generators, in-panel switch connections, machine and engine interconnections.
