Frequently asked

Glossary

1

Wire drawing

Cold forming process in which wire rod is pulled through a series of dies to reduce its diameter; the core production step that the drawing and annealing lines at Wire Eurasia are built around.

2

Rod breakdown

The first drawing stage, taking copper or aluminium wire rod of roughly 8 mm down to an intermediate gauge before finer multi-wire drawing.

3

Drawing die

Tungsten carbide or synthetic diamond tool that sets the finished diameter, ovality and surface quality of drawn wire; die suppliers and re-polishing services sit alongside drawing machine makers at the fair.

4

Capstan

The driven drum that supplies the pulling force in a drawing line. Slip-type and non-slip capstan designs determine the wire tension and the maximum speed a machine can reach.

5

In-line annealing

Resistance or inductive heat treatment applied directly after drawing to restore ductility; a frequent buying criterion for wire producers comparing drawing lines.

6

Bunching

Twisting many fine wires together into a flexible conductor. Bunching machines and double-twist bunchers are a separate equipment category from rigid stranding.

7

Stranding

Laying up several wires or strands in a defined helix to build a larger conductor, typical for power cables and overhead line conductors.

8

Double-twist buncher

Machine that applies two twists per spindle revolution, roughly doubling output versus a single-twist machine for the same floor space.

9

Extrusion

Process that applies insulation or sheath by forcing a molten polymer compound around the conductor; insulation, sheathing and co-extrusion lines are a main hall category.

10

XLPE

Cross-linked polyethylene, a thermoset insulation used for medium and high voltage power cables. Cross-linking is achieved by peroxide, silane or electron beam methods, each with different downstream equipment needs.

11

LSHF / LSZH compound

Low smoke halogen-free (or zero halogen) compounds used where fire safety and low toxic smoke matter, such as tunnels, rolling stock, hospitals and public buildings.

12

Enamelled wire

Copper or aluminium wire coated with one or more layers of enamel for windings in motors, transformers and small inductive components.

13

ACSR

Aluminium conductor steel reinforced, the standard bare conductor for overhead transmission and distribution lines, combining aluminium strands around a steel core.

14

Pay-off and take-up

The unwinding and rewinding ends of a production line. Pay-off and take-up selection controls tension stability, spool change time and therefore line efficiency.

15

Spark tester

In-line quality control unit that detects pinholes and insulation faults in the extruded layer by applying a high voltage across the cable as it passes.

16

Cable compound

Formulated polymer granulate, with fillers, flame retardants and stabilisers, supplied to cable makers and processed on the extrusion lines shown at the fair.

17

IEC 60228

The international standard that classes conductor sizes and resistance values; buyers comparing conductor specs at the show often quote class 1, 2, 5 or 6.
