Basbar
Structure
In every power plant, substation, generators, transformers, wires and cables with equal voltage level and in phase, they are connected to each other by means of a conductor called BUSBAR.
Alumtek
In the busbar, the energy of the generator or transformers is connected and transferred to the next parts.
In other words, the busbar is a means of collecting, transferring and distributing electrical energy, the history of its use goes back to the history of the power plant, and since its inception, it has almost kept its current form, and only changes and improvements have been made in its production technology and material.
Alumtek
Basbars have various forms; Its flat and flat type is used in low voltages and is more famous as a busbar.
The stringed type, which is actually a conductor, is composed of several strands of wire and tubular busbars, which are mainly used in electrical energy production and conversion centers.
This category of busbars is usually produced from copper or aluminum and its alloys.

Application
For many reasons, including:
Thermal radiation and heat exchange better than aluminum compared to copper, creating less ash during ignition and burning of aluminum, more reaction with sulfur in the open air and the formation of a copper oxide shell that reduces electrical conductivity;
Aluminum is more useful than copper.
The most widely used alloy for making tubular busbars is alloy 6101 (according to the international union nomenclature). Aluminum Association) with T6 heat treatment.
This heat treatment is used when high mechanical strength and good electrical conductivity are desired, and the concept is that the product is first subjected to dissolution heat treatment and then artificial aging.
Alloy 6101 has high corrosion resistance and has good welding and soldering capabilities; The machinability of this alloy is medium.
Alumtek and Alumrad group of companies have been producing and offering all kinds of busbar sections with external diameters of 60, 80, 100, 120, 180, 200mm with thicknesses of 6, 8, 10, 12mm and now with the production of 250/6 busbar, while completing the portfolio of products, it meets the full needs of the country’s electricity industry. In this regard, he has made a high.
Features
Reference standards
Busbars are produced in accordance with the requirements of ASTM B317 standards.
