Processing Process

• 01

  CCDR（Continue Casting Direct Rolling

  Put the Aluminum ingot into the melting furnace, moulding it into Aluminum rod or Aluminum alloy rod of diameter 8-9.5mm after melt.

  
• 02

  Wire drawing

  Draw the electric round aluminum rod into wire of diameter 0.15-5mm with high-speed drawing equipment.

  
• 03

  Stranding

  Strand one or more wire layers surrounding the concentric wire into conductor.

  
• 04

  Insulation

  Extrude the conductor with the XLPE raw material surrounding it, material cross link under high- temperature and high-pressure, then cooled to be insulation.

  
• 05

  Cabling

  The process to bunch several insulated conductors into one.

  
• 06

  Metal armoring

  In order to protect the insulated conductor, surround the insulated conductor with magnetic or non magnetic metal material, like steel wire or aluminum wire.

  
• 07

  Sheath

  Extrude the cable after surround the semi-finished armored insulated conductors with melting PVC or PE.

  
• 08

  Test

  The power cable plays an important role in power transmission lines, can be used only after strict testing.
