Copper And Silver Stranded Conductors For Flexible Cable

Multi-strand copper and silver conductors for cables that need flexibility without giving up cross-section.

Copper Stranded Wire produced by Superfinewire
Overview

What Copper Stranded Wire Is And How It Is Built

Where a single conductor cannot deliver both the cross-section and the flexibility a cable needs, stranding does it. We produce copper stranded wire and silver stranded wire in bare copper, oxygen-free copper and copper alloys, and the copper can be annealed soft or left hard depending on whether the finished cable is being asked to bend or to hold its shape. Stranded constructions can also be mixed with tinsel wire in the same conductor when bending strength has to rise further.

Fit

Who Specifies This And Why

Who this range is for

  • Cable assemblers building flexible power and signal cores
  • Charging pile and automotive circuit cable makers
  • Industrial equipment builders specifying drag chain cable
  • Buyers sourcing oxygen-free or plated stranded conductor to a drawing

Problems it is specified to solve

  • A solid conductor of the required cross-section is too stiff for the bend radius of the cable.
  • Repeated flexing concentrates stress on a single strand and propagates a break.
  • Oxidation on untreated copper strands degrades termination over the shelf life of the product.
  • Conductor resistance has to be held to a value while outer diameter stays capped.
Capability

What This Range Gives Your Cable

Core advantages

  • Available in bare copper, oxygen-free copper, tin-copper, iron-copper and silver-copper alloy.
  • Soft annealed or hard copper depending on the flex behaviour the cable needs.
  • Tin, silver or nickel plating applied from 0.3 um to 2 um, set by performance rather than by a stock option.
  • Can be combined with tinsel wire in one conductor to lift bending strength.

Application scenarios

  • Charging pile cable cores
  • Automotive circuit electronic cable
  • Drag chain and robot cable
  • Flexible power leads in industrial equipment
Questions

Copper Stranded Wire: Frequently Asked Questions

Do you supply oxygen-free copper?

Yes. Oxygen-free copper is one of the standard metal materials we work in, alongside bare copper, tin-copper alloy, iron-copper alloy, silver-copper alloy, nickel-chromium alloy, nickel-iron alloy and copper-nickel alloy.

What is the difference between your soft and hard copper wire?

Soft copper wire is annealed, which lowers its stiffness and suits conductors that have to flex. Hard copper wire has not had that treatment and holds form better. Both can be supplied.

Can you plate stranded wire?

Plating in tin, silver or nickel is available with a coating thickness customizable in the 0.3 um to 2 um range. The coating is uniform and continuous, with strong adhesion and a smooth surface free of discoloration, particles and mechanical damage.
