T he demands on power cable fall into two categories. The first is concerned largely with
conditions of installation (in buildings, in-ground, overhead, exposed). The second
category requires the cable to deliver its charged payload reliably in conditions as
they arise throughout a long and tireless life in service.
Power cable technology demonstrates that the industry is more than equal to the challenge.
The techniques of power cable manufacture, materials, and machinery are one step ahead
of demands. The companies whose products and services, reviewed here, address the needs
of the industrial electrical industry intend that it will always be so.

Cable processing with power
and precision
Many cable processing machine manufacturers aim their development
mainly at small cable diameters, but Metzner has developed the
AM 5000 Series, two models that can accommodate large cable
diameters and differ from one another only in their equipment levels.
Both models are designed to process cables up to 30mm diameter and
cross-sections of up to 185mm² and are distinguished by their high
productivity and robust construction. Their high conveying speed
of up to 150 metres per minute is particularly useful for longer cable
cut lengths and significantly increases the output rate. At the same
time, the robust design ensures a long service life, even in continuous
production conditions.
For all processing tasks calling for a high-precision cut, Metzner offers
the AM 5350 model with a rotating knife cut that processes the cable
insulation sheath round its complete circumference.
In this process, a knife is driven in to a pre-programmable cut depth and cuts the cable with optimal results. Total cable processing
also involves further activities, such as printing and coiling. For this purpose, the AM 5000 Series is designed so that individual
add-ons can be easily integrated.
