Conductor (solid wire or wire)
The application of a cable determines the choice of the
conductor. There are three different conductor categories:
Solid wire,
stranded wire and tinsel
cord.
First choice in the production of specialized cables are wires in
form of either wire bundles or concentric wires (e.g. Unilay wires, stainless-steel wires).
At SENSOCAB, wire cross-sections range from 0.0019 mm² (AWG 44)
up to 1.3 mm² (AWG 18), depending on the
wire construction. A special type of conductor is the
drain wire.
The rapid development in the production of special cables demands for highly
effective and reliable conductive material. SENSOCAB uses the following
wire material:
- Copper - Due to its very high electric
conductivity and excellent formability in warm and cold condition,
electrolyte copper is the first choice in today's cable technology.
Depending on workmanship and application, copper is available with different
surfaces (blank, tin and silver plated).
- Alloy - Applications demanding for extreme
torsion-rotation and low bending radii require the use of copper "alloy",
since it
has exceptional tension strenght and sturdiness.
- StaKu - Staku-wires are steel-copper composite
wires. The steel core is copper-plated by electrolytic technology to
provide the wires with high mechanical stress resistance.
- Semiconducting synthetics or carbon fibres
- Tinsel - Tinsel cord provides the best
torsion-rotation-stability. Tinsel cord consists of flat-rolled wires (= Laminetten)
wrapped around textile yarn (supporting
thread). Kevlar, Nylon etc. serves as supporting thread. The flat-rolled wires,
either blank, silver or tin plated copper wire have a 01 - 0.03 mm
thickness and 0.20 mm width.
