Shielded vs. Unshielded Cables in Power Over Ethernet

WCTI 1462 Views

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.

Production of Micromasterbatches to Improve Dilution Process in the PVC & Cable Industry

WCTI 1694 Views

The micromasterbatch is a type of masterbatch with a reduced pellet size, applicable in both PVC and polyolefins, which provides better control and optimal color homogeneity. A key bet in the sector in order to make cable manufacturing cheaper, speed up production, gain efficiency and guarantee the highest possible quality. And the fact is that the reduced size of the Delta Tecnic masterbatch ensures a faster dilution, as it melts and incorporates the compound earlier

Webinar Explores Wire Harness Assembly in Mexico

WCTI 1761 Views

Hourly direct labor rates can be as low as $2.30 per hour in Mexico, according to Entrada Group, which is co-hosting a webinar with Wire & Cable Technology International (WCTI) magazine on May 12, 2021. “This makes Mexico the most cost-competitive location in the Americas for wire harness assembly,” according to Entrada, which has more than two decades experience guiding wire harness-makers in setting up and running their own operation in Mexico

Wire Breaks and the Role of Drawing Machine Operators

WCTI 2782 Views ,  ,  ,  , 

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

WCTI 1731 Views ,  ,  ,  , 

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.

Spotlight on Bows

WCTI 3112 Views ,  ,  ,  ,  ,  , 

Rotating machines such as stranders, bunchers, twinners and cablers use flyer bows to produce helically twisted wires, conductors and cables. All products being processed on these machines come in contact with the bow. More than half of the power required to run the corresponding machine goes toward rotating the bows. In addition, a good amount of the noise generated by a rotating machine comes from the bow, and less aerodynamic bows usually make more noise. Consequently, these bows are pretty important, and they are a main factor in determining the level of success in your rotating equipment operations.

Wire Rod Coils for International Transport

WCTI 1700 Views , 

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.
