electrical wire insulation extrusion applying an insulation layer around a flexible or solid conductor made of various fine bare wires or around a sole rigid bare wire. This process is carried out on an extrusion line (insulating line) which includes an extruder fed continuously with granules of PE, PVC or any other insulating material. The extrusion line will be mixing and heating the granules until they reach the correct temperature and viscosity. The wire will go through the cross head on the extruder in order to get the insulation layer of the desired colour. After this it will go through a trough filled with running water which will be cooling the applied material and thus solidifying it very quickly. The conductor will be going through various testing equipment in order to detect possible faults (spark tester, diameter controller, etc.) This process is generally realized at high speed.
The video is trial running of TZ-EP 80+45 PVC insulation line at Riyadh,KSA.
Basic processing:
Line speed: 228m/min ,flexible copper wire 50*0.25mm(2.5 sq.mm) with insulation layer 0.6mm
