Description
Photovoltaic Wire Tandem Extruder with One-Step Extrusion and 200m/min Speed for High Efficiency
Product Overview

PV Cable is a special connection cable in solar power generation systems, 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 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 (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.
