Rigid stranding technology is a cornerstone of POURTIER’s wire and cable expertise. With decades of global installations and continuous technical development, these rigid strander lines are engineered for demanding power cable and conductor applications, from medium voltage through to EHV and HVDC systems.

Core Capabilities

• Heavy-duty rigid stranding lines engineered for copper, aluminium, and alloy conductors

• Fully custom-engineered configurations, tailored to customer production requirements

• Available cage sizes typically ranging from 630 mm to 800 mm bobbins

• Designed for single-wire stranding, with options for compacted or non-compacted conductors

• Supports round and sector conductors, straight or pre-spiralled

 

Conductor & Cable Types

• Copper, copper alloy, aluminium, and aluminium alloy wires

• Stranding capacity up to 132–169 wires, depending on configuration

• Suitable for:

  • Extra High Voltage (EHV) and High Voltage cables (HVAC / HVDC)

  • Pre-spiralled sector cores for Milliken conductors

  • Overhead conductors: AAC, ACSR, AAAC, ACCC, ACSS

  • Steel wire armouring

  • Copper wire screening

  • Flexible Class 5 conductors

  • Control and specialty cables

 

Production Range

• Cross-section capacity:

• • Up to 4,500 mm² (Copper)

  • Up to 5,000 mm² (Aluminium)

• Compaction options:

  • Die compaction

  • Roller compaction

  • Combined die + roller compaction

 

Key Design Features & Advantages

• Optimised smooth wire path with minimal deviation angles

• Highly stable and consistent wire tension control

• Precision trapezoidal stranding heads for accurate angular positioning

• Heavy-duty mechanical design for long service life

• High-grade dies and compacting rollers for superior conductor geometry

• Large-diameter capstans with pulling forces up to 80 tons

• Modular line layouts offering excellent flexibility

• Extensive know-how transfer and technical support from OEM

 

Stranding Configurations (Typical)

• Common wire counts include:

  • 37, 54, 61, 84, 91, 127, 132 and up to 162 wires

• Automatic speed optimisation as bobbin diameter reduces during operation

• Layouts available for both compact footprints and high-output production halls

 

Handling & Loading Options

• Side-loading carriages (reels on floor or rack)

• Multi-reel loading systems (4 or 6 reels)

• Tilting loaders with optional automatic reel rotation

• Designed for safe, efficient handling of heavy copper and aluminium reels

 

Typical Applications

• Power transmission cables

• High-current industrial cables

• Overhead line conductors

• Armoured power cables

• Screening and shielding layers for MV, HV, and EHV cables
