Extruded Aluminum Tube or Pipe for Electrical Engineering

Aluminium has been applied for almost all branches of electrical engineering for many years as a conductor material. In addition to the pure aluminium, its alloys are also excellent conductors, combining structural strength with an quite acceptable conductivity.
Aluminum is used everywhere in the electrical industry. Motors are wound with it, high voltage lines are made with it, and the drop from the power line to your house’s circuit breaker box is probably aluminum.

Aluminium extrusions and rolling for electrical engineering:
+ aluminium wire, cable, strip with drawn or rolled edges.
+ aluminium tube / aluminium pipe or sections by extrusion
+ aluminium rod or bar by extrusion

The comparatively light Aluminum wires decrease the burden on grid towers and expand the distance between them, reducing costs and speeding up construction times. When current flows through Aluminum wires, they heat up, and their surface is coated with the oxide layer. This film functions as excellent insulation, protecting the cables from external forces. The alloy series 1ххх, 6xxx 8xxx, are used to create Aluminum wiring. This series produces products with longevity that exceeds 40 years.
An aluminum rod – a solid aluminum rod with a diameter from 9 to 15 mm – is a workpiece for an aluminum cable. It is easy to bend and roll up without cracking. It is almost impossible to be torn or broken and easily sustains significant static loads.

The rod is produced by continuous rolling and casting. The resultant casted workpiece is then passed through various roll mills, which reduce its cross-sectional area to the needed diameter. A flexible cord is produced that is then cooled and then rolled into huge circular rolls, also known as coils. In a specific manufacturing facility for cable, the rod is transformed into wire using wire drawing machines and dragged into diameters ranging from 4 millimeters to 0.23 millimeters.
Aluminium rod is used exclusively for grid substation busbars at 275kV and 400kV (Gas-Insulated Transmission Line – GIL) and is increasingly being used at 132kV for substation refurbishments and redevelopments.

Now what we can supply is extruded aluminium tube/pipe, bar/rod, classics alloys are 6063, 6101A and 6101B with good conductivity between 55% and 61% International Annealed Copper Standard (IACS). The max outer diameter of pipe we can supply is up to 590mm, the max length of extruded tube is nearly 30mtrs.
