Nano crystalline diamond dies Ajex & Turner has been engaged in the manufacture of a variety of wire drawing and compacting dies and tools for the wire and cable industries since 1962.

Ajex & Turner states that the advantages of VNT nano dies for wire drawing and compacting include lower friction, for better copper and aluminium utilisation; better surface quality – high and bright surface finish; an improvement of 3-4 per cent in raw material utilisation and bet ter life than PCD and tungsten carbide dies; zero per cent tolerance for the entire working life for any metal; and no die pol ishing/re-cutting required for any metal. For aluminium/copper RBD, nano dies are claimed to be better for a continuous process with no metal loss and tolerance breakage or scratches on the wire. To avoid rust, the casings are made from stainless steel grade 304.

The Roxtec sealing modules used in the waveguide seal adapt to different sizes of fibre optic cables and can be used to build in spare capacity in the transit. Roxtec International AB www.roxtec.com

The VNT nano dies can be used to draw copper/aluminium for stranding, compacting, bunching, rod break down (RBD), etc. They can also be used to draw aluminium alloy wire, nickel silver wire, brass, copper tubes or any metal, and to draw stainless steel, and high- and low-carbon steel wire up to 0.6%C, welding wire or any hard/soft wire of any size and hardness.

VNT nano dies are made with multi-layer coatings of nano crystalline diamond through vapour deposition, which pro- vides a smooth surface with low friction. The dies can be made in sizes from 0.5 to 100mm for drawing, compacting, TW, sector and Z-shapes.

The WaveGuide Seal ES is a penetration seal designed for routing of non metallic fibre optic cables into a shielded enclosure while maintaining the enclosure’s electromagnetic integrity. The high-performance product protects

The increasing use of unshielded fibre optic cables in the digitalisation era necessitates the protection of sensitive communication equipment against

Robust and maintenance-free steel cable carriers

electroplating plants, in power plant applications and in other applications under radioactive radiation. The company’s steel cable carriers also find application offshore, owing to their resistance to seawater and UV radiation. The Steel-Line range includes a number of steel cable carriers in various sizes and configurations, with matching accessories. The range of products is tailored to the respective operating and environmental conditions, with corresponding design details. For example, Kabelschlepp designs the side bands with link plates in different geometries, including an open stroke system with a self-cleaning effect, in order to minimise wear caused by dirt and to achieve a long service life. Steel Line products do not require lubrication.

Steel-Line cable carriers, from Tsubaki Kabelschlepp, have been designed for extreme applications. Steel cable carriers are used in the traditional applications of heavy machinery manufacturing, steelworks, mining and deep drilling. Depending on the design, steel carriers can withstand temperature loads or application dependent maximum values of up to 400°C for short periods; stainless steel versions can even withstand temperatures up to 1,000°C. They are also resistant to chemicals and radiation, and deliver performance on handling robots and manipulators in chemical plants. Stainless steel cable carriers, available from Tsbuaki Kabelschlepp at three different quality levels, can be used in the environment of acid baths in

With high load capacity, steel cable carriers handle extreme mechanical stress and operating conditions

Tsubaki Kabelschlepp knows of cases where a cable carrier has been in use for more than 50 years. Steel cable carriers can also be recycled at the end of their service life, conserving resources and protecting the environment. Tsubaki Kabelschlepp GmbH www.kabelschlepp.de
