● The machine use 4 pcs of Φ9.5mm aluminum rod(A2 rod, According to China National Standard GB/T3954) feeding into the main extrusion machine after surface cleaning treatment to apply Φ60-Φ170mm aluminum sheath.

● The extrusion main machine use upper and lower single wheel double groove structure, with advanced forming technology and high production efficiency.

● After the cable core is paid off from the pay off stand, and go through into the extrusion mold with the same speed of the aluminum sheath tube, forming a loose cable aluminum sheath. When the cable through the extrusion mold, there is a water cooling jacket protecting the cable core.

● After the aluminum tube come out from the extrusion mold, it will be cooled by the cooling water immediately to avoid any scald to the cable core.

● The sheathed cable goes into the corrugation unit to corrugate the aluminum tube to form a protection metal sheath of cable as per the standard or user’s requirement. Then the corrugated aluminum sheath cable will be taken up.
