How cold-applied technology became the new normal
Recent decades have seen a gradual shift away from heat-shrink cable accessories in favour of cold-applied technology. So, what is behind this shift?
Child of the 80s
Heat-shrink technology requires highly skilled jointers to perform the installation
Heat-shrink technology was developed in the early 1980s and enjoyed huge success. It uses extruded plastic tubing which, when heated, shrinks to form a tight seal over both the cable and the cable accessory coupled to it. Cable accessories with heat-shrink technology came to be used widely around the world due to their good insulating properties, impressive mechanical strength, and indefinite shelf life. On the other hand, it is impossible to guarantee uniform insulation of the cable when using heat-shrink technology, as this requires an even heating at each cable section, which in turn is highly dependent on the skill and experience of the jointer. In former decades, NKT was one of the many manufacturers to supply cable accessories that utilised heat-shrink technology.
New kid on the block
Cold-applied products make the installation simpler and faster – therefore providing time and cost savings
But the journey has not yet ended, and the technology is being developed further. Stay tuned for more info on this topic – we have some great news to share with you soon about further product developments!
