Photovoltaic Wire String Extrusion One-Step Extrusion Production Line 200m/min

PV Cable is a special connection cable in solar power generation system, used for series connection between components and power transmission from components to inverter. Its core value lies in:
Weather resistance: long-term exposure to ultraviolet (UV), high temperature (-40℃-120℃), humidity and chemical corrosion environment;
Safety: flame retardant, low smoke zero halogen (LSZH), reducing fire risks;
Electrical stability: low resistance design, reducing energy loss and improving system efficiency;

Applications:

Used for one-time extrusion of photovoltaic cable insulation and sheath, meeting the requirements of TUV and UL certification;

Main process parameters:

Main Components of a Wire Extrusion Line

1. Pay-off Stand

   • Holds and unwinds the bare conductor (e.g., copper or aluminum wire) for feeding into the extrusion process.

2. Straightener (optional)

   • Ensures the wire is straightened before entering the extruder for uniform insulation.

3. Extruder

   • The core component of the line.
   • Melts and applies the insulation material (like PVC, PE, XLPE, etc.) uniformly around the conductor.
   • Includes barrel, screw, and die head systems for precise material flow and coating.

4. Crosshead Die

   • Shapes and centers the melted insulation material around the wire.
   • Ensures consistent wall thickness and concentricity.

5. Cooling Trough (Water Trough)

   • Rapidly cools the extruded wire to solidify the insulation.
   • Typically uses water or air cooling systems.

6. Diameter Gauge (Laser Gauge)

   • Measures the diameter of the insulated wire in real time.
   • Helps maintain dimensional accuracy and quality control.

7. Spark Tester

   • Detects insulation faults or pinholes by applying a high-voltage electric test.

8. Capstan (Caterpillar Haul-off)

   • Pulls the wire through the extrusion line at a consistent speed.
   • Ensures proper tension and synchronization.

9. Take-up Machine

   • Collects the finished insulated wire onto a spool or drum for storage or further processing.
