taping, armouring & sheathing of cables
Feature
T
hese are the defensive specialities, their very names suggestive of battle
equipage. Without them, no cable would be diminished in its rated capacity or
in any other specification, as tested in laboratory conditions but the prudent
person would not wager on its lasting very long in the real world.
Taping, armouring, and sheathing – if protection and economy are both to receive their due
– must be appreciated for the important and exacting industrial processes they are. Consider
two runs of product being readied for shipment from a mill:
a bundle of electrical cable is fitted with a sleeve to protect against contaminants;
•
a cable made up of two dozen conductors twisted together receives an application of
•
elastomeric material as it is drawn through the head of an extruder; the elastomer is cured
by heating, then cooling; the cable is rotated about its axis preparatory to undergoing
a half-dozen more procedures on its way to the shipping bay.
Both fall into the category of sheathing: like armouring and taping, a procedure with heavy
responsibilities that must be met across a broad range of requirements. They are all in safe
hands with the experienced professionals whose products and services are reviewed in this
section of EuroWire.
