taping, armouring & sheathing of cables

Rigid cage screening Rotating cages from Cortinovis have been developed for single and multi-wire screening of low, medium and high voltage cables with copper or aluminium. Special low fiction pneumatic pintles permit handling of fine wires, and each wire, from two to eight per bobbin, has individual break control. Tapes and yarns Smeets NV/SA, established in 1921, is a distributor of cable components such as woven semi-conductive tapes, waterblocking tapes and yarns, aramid yarns, FRP strength members, anti-fire fibreglass and mica tapes. Smeets’ high quality products are widely used by most of the major cable manufacturers across America and Europe.

A diving disc located at the closing point ensures accurate spacing of the wires. A full range of taping heads is available for semi-conductive, non-woven and plastic tapes. Using caterpillars for pulling, two belts with individual motors provide electronic balance of pull.

Taping, armouring and sheathing of cables Tensor Machinery provides a complete armouring system for steel, aluminium and copper tape applications from 15 to 100mm tape widths. The equipment includes tape pay-offs, accumulators, welders, corrugators and rollforming. For the tape pay-offs Tensor offers driven and non-driven designs, depending on the tape material and the type of tape accumulator used. Tensor also offers up to 600 feet of tape accumulation to ensure the line never slows down when performing a tape weld. The tape accumulator can be designed for either smooth tape or corrugated tape.

The tape welder can weld steel, aluminium and copper tape in seconds, with a small overlap weld. This is a resistance type welder where the tape maintains strength of 90 to 100% after it is welded. For the corrugator, Tensor provides an easily adjustable corrugation depth using a single crank lever, giving an even corrugation across the tape width. Both the upper and lower corrugator rollers can be driven to provide an accurate corrugation pitch; the corrugator can be provided with a variety of corrugation pitches. For tape forming the company suggests rollformers – a series of rollers that smoothly form a tape into a round tube shape with a slight overlap. Tape widths as small as 15mm can be formed into a round tube. There is virtually no friction in forming so high speeds can be obtained without heating the tape or damaging the tape coating. All Tensor armouring equipment can be designed to operate as a complete system or individual components can be purchased for integration into any existing armouring line.
