Sikora: Overview about different techniques for diameter measurement By Editor (25 Oct 17 5:15) in Technical Papers
Advantages of the CCD line sensors of the Sikora Laser Series 2000/6000 An increasing quality awareness in many areas of daily life and especially in the field of industrial goods has been observed for some years. Manufacturers of wires and cables have also been investing intensively in measuring and control technology as well as inline control over the last years. At the same time, amongst others, the diameter and ovality of products play a crucial role. These cable parameters can be measured in the production line by different techniques, which shall be described in the following article. Until now, three different methods for

Measuring devices for quality control of optical fibers in the drawing tower for a perfect fit in subsea cables By Editor (20 Sep 17 5:15) in Technical Papers
Introduction Recent studies show a growth of undersea optical fiber connections for the future. “Optical fiber is considered to be a good option to carry higher data rates over longer distances than copper cables. By 2020, an increase in subsea processing will generate more data, which will make the high bandwidth and longer transmission distances of optical fibers more attractive” says ResearchandMarkets in its report on ‘Global Fiber Optic Connectors Market 2016-2020’. They are currently observing two developments in manufacturing optical fibers. On the one hand, there are countries such as China and the USA advancing further into the optical fiber market as

Cables for offshore wind turbines By Editor (20 Sep 17 4:30) in Technical Papers

According to the Fraunhofer Institute for Solar Energy Systems, wind turbines between the North Sea and the Alps generated a total of 85.4 billion kilowatt hours of electricity last year. Figures in the wind power sector show that its share accounted for more than

Uhing Motion Drive® in Operation – a Visit to the Customer By Editor (24 Aug 17 4:10) in Technical Papers
In April 2016, the latest innovation by Joachim Uhing GmbH & Co. KG was rolled out to the public: The Uhing Motion Drive® is an Uhing rolling ring drive that was endowed “intelligence” by integrating sensors and electronic controller. A visit to a company operating it illustrates how the system proves its worth during operation. For many years, the Uhing customer, a steel refiner located in North Rhine Westphalia, has been using a machine that winds flat wire on a spool. The solution used so far caused frequent problems during winding that in turn resulted in interruptions of the automated downstream process. Also, fully wound spools had to be rewound often more carefully in order to obtain the required winding pattern. The

Inspection and analysis of XLPE and HPTE material at medium and high-voltage cable production By Editor (15 Feb 17 5:10) in Technical Papers
Abstract Plastics that are used for the insulation of medium, high- and extra-high voltage cables have to comply with the highest purity standards. Most commonly XLPE (cross linkable polyethylene) material is used for the insulation of cable. For cross linking of the XLPE the cable passes through a CV-tube (continuous vulcanization tube) where it is exposed to high temperatures for the cross linking. Typically at the manufacturing of these types of cables the CV tube is filled with nitrogen and operated at a pressure of 10 bars. Before the cable can be further processed, such as the

A development from Germany based Wafios By Editor (26 Oct 16 6:10) in Technical Papers
In the shape of iQsmartbend, Wafios has developed a patented, award-winning software solution designed to optimize bending processes for wire and tubes The phenomenon of vibrations can be observed in almost every area of our daily lives. In some cases it is undesirable and may even be dangerous, but in others, it is the intended result of a conscious action. Intervening measures can be put in place in both cases, as a means of either absorbing (or at least minimizing) vibrations in the former case, or generating (or amplifying) them in the latter. The pendulum of a grandfather clock and the swinging-out motion of the seats on a fairground swing ride are

Structural Return Loss (SRL) and FFT-Frequency Analysis By Editor (28 Sep 16 4:05) in Technical Papers
Sikora measuring devices provide FFT analysis and SRL predictions The production of state-of-the-art cable products, e.g. data cables, requires a constant monitoring of the cable diameter, concentricity and/or cable capacitance with regard to smallest, periodically occurring cable parameter fluctuations. These fluctuations may occur from irregularities such as

Nothing would roll without them: wire products in railway technology By Petra Hartmann-Bresgen M.A. (09 Mar 16 7:20) in Technical Papers
The wire, cable and wire-processing industry and the wire 2016 trade fair It is now impossible to envisage today’s world without trains and other railborne vehicles. In the 19th century they made a key contribution to industrialization and today are fully integrated in the globalization of markets and growing urbanization. Rail-mounted vehicles can transport large volumes of people and goods quickly, safely and efficiently even over great distances and, when electrically powered, are very environment-friendly in their use of electricity obtained from regenerative sources. The prerequisite for rail systems being able to function at all, however, is the products manufactured by the wire and

All wired up By Petra Hartmann-Bresgen M.A. (26 Jun 13 5:00) in Technical Papers
Wire keeps the world in motion: the current state of the sector Without wire, the world would grind to a standstill. Bicyclists ride around on spoke wheels, power cables run overhead and below the ground, supplying homes and companies with energy. Even armoured concrete is reinforced and stabilised with wires. Reliability of materials and their quality therefore are of high priority for makers and buyers of wire. Only those who rise to the challenge will survive in the market. The financial crisis at the end of the last decade also hit the wire sector with full force; a high wire act for some companies facing difficult times. However, the economy has picked up and so has

How to save your Air Wiping Costs By Editor (18 Jul 12 4:50) in Technical Papers
This mini air wipe, by observing the basic physical rules governing its operation, cleanses a Ø 1.2 mm wire at 900 meters/minute using 0.24 liters/sec of compressed air. An air wipe converts the potential energy of compressed air into kinetic energy by forcing the air through constricting orifices. Its performance is governed by 2 physical principles, namely: 1. K.E. = ½ Mv2 ...Equation of Kinetic Energy 2. A1v1 = A2 v2 Equation of Continuity Where: M = mass, which in an air wipe is the air flow v = velocity of the air A = cross sectional area The equation of Kinetic Energy (K.E.) reveals

Cable Materials Matter By Simon Sutton (20 Jun 12 5:20) in Technical Papers
For many years, utility engineers have often regarded distribution cables as a bit boring and possibly even as a commodity – simply because they are generally so reliable compared to other network assets. Even at transmission voltages, an out-of-sight out-of- mind attitude can easily develop. This attitude is perhaps reinforced because other assets often require more maintenance and are genuinely more visible than cables. A feeling can develop that all cables installed in all environments will operate without problems; so unfortunately cable is often chosen on price rather than as a critical part of the power system. In an increasingly global market and with financial penalties for non-delivery of power, choosing any old
