Cutting-Edge Heat Stabilizers for PVC Wire & Cable

In the past, most heat stabilizers for PVC wire and cables were lead-based. As awareness of safety and health issues grows around the world, health and environmental regulations are becoming more and more stringent every day. The European Chemical Agency (ECHA) notes in a risk management option analysis (RMOA) that lead and lead compounds are classified under the CLP Regulation as category 1A substances toxic to reproduction, toxic following prolonged and repeated exposure, and hazardous to aquatic life. Lead stabilizers are therefore now banned for various applications in many countries and have been replaced by alternatives

Shielded vs. Unshielded Cables in Power Over Ethernet

The study described in this article, was carried out on different types of cables with different conductor sizes and bundle sizes. At the end of the article, some interesting observations and findings are included. One test for PoE takes approximately 16 hours of time, which is huge in the day in and day out work for the development and quality engineers to spare for each cable. So during this study, a simulation model was generated, which predicts the temperature rise for different types of cables, bundle size and conductor size for the given environmental conditions. This article also gives some insight on the validation of the model versus actual measured temperature for the given test configuration.

Wire Breaks and the Role of Drawing Machine Operators

Wire breaks can occur during the wire drawing process. They are the undesirable result of unfavorable interactions of forces, tensions and other physical phenomena in the wire material which exceed its tensile strength. The consequences are increased machine down times and scrap production.
One of the main types of wire breaks are called “cup-andcone” breaks because one end of the broken wire is conelike and the other end is deepened like a cup or like a crater. These breaks usually occur when the wire passes through a drawing die

Durable & High-Contrast UV Laser Markings in PTFE Wire Insulations

Due to issues relating to product liability and environmental concerns associated with the traditional method of ink-jet printing on plastics, laser marking and engraving have gained huge significance as alternative techniques for product recognition and identification.
Laser marking aids product identification by creating permanent marks on plastic surfaces with a visually controlled laser beam.

Wire Rod Coils for International Transport

Turkish steel manufacturer, Kardemir (Karabük Demir Çelik Fabrikalari A.S.), based in Karabük, has placed an order with SMS group for the replacement of selected key components of its wire rod mill. The wire rod mill to be modernized is part of the SBQ (Special Bar Quality) plant supplied by SMS group in 2013, which has an output of 700,000 tons of bar steel, bar-in-coil and wire rod every year.
