At GREMCO, we rely on state-of-the-art materials and technologies to meet the highest demands &#8211; including <strong>HiVec<\/strong>, a specially developed, foamed <a href=\"https:\/\/www.gremco.de\/en\/wire-and-cable-products\/ptfe-fep-wires-cables\/\">PTFE<\/a> (polytetrafluoroethylene) that is used as a dielectric in our coaxial cables. HiVec stands for \u201c<strong>High Velocity Coax Cable<\/strong>\u201d and stands out from conventional PTFE due to its particularly low dielectric constant. This innovative material ensures exceptionally high signal quality, especially in high-frequency applications.<\/p>\n<p>&nbsp;<\/p>\n<h2>What is a dielectric, and why is it important?<\/h2>\n<p>The <strong>dielectric<\/strong> is an insulating material that is located between the inner conductor and the outer shielding of a <a href=\"https:\/\/www.gremco.de\/en\/wire-and-cable-products\/coaxial-cable\/\">coaxial cable<\/a>. It has a direct influence on signal transmission. Ideally, a vacuum &#8211; with a dielectric constant of 1 &#8211; would be the perfect dielectric for signal transmission, but this is technically difficult to realize. This is where PTFE comes into play, which has a dielectric constant of around 2.1. However, the foamed structure of HiVec allows this value to be reduced to around 1.7 to 1.9, which speeds up signal transmission and reduces transmission losses.<\/p>\n<p>&nbsp;<\/p>\n<h2>HiVec: Higher propagation speed and reduced attenuation losses<\/h2>\n<p>A key advantage of HiVec is its ability to improve the propagation speed of the signal. This optimized speed means that the signal is routed through the cable more efficiently, which is particularly important at high frequencies, where transmission losses often increase significantly. HiVec cables allow signals to be transported over greater distances without compromising on quality and precision. This makes HiVec cables the ideal solution for applications where signal quality and speed have top priority &#8211; such as telecommunications, radar technology, and military applications.<\/p>\n<p><img loading=\"lazy\" class=\"alignnone  wp-image-4396\" src=\"https:\/\/www.gremco.de\/app\/uploads\/2020\/05\/GREMCO_KabelLeitungen_Koxialkabel_Signal\u00fcbertragung.jpg\" alt=\"GREMCO coaxial cables\" width=\"250\" height=\"250\" \/><\/p>\n<p>&nbsp;<\/p>\n<h2>Technological excellence at GREMCO<\/h2>\n<p>The production of HiVec cables is based on high-quality standards and state-of-the-art manufacturing technologies. The inner conductor of many of our coaxial cables is made of silver-plated copper, which has been specially selected to minimize the so-called skin effect. This effect causes the current to flow mainly on the surface of the conductor at high frequencies, which can lead to energy loss. By silver plating, we improve conductivity and enable low-loss transmission even in demanding applications.<\/p>\n<p>Together with our specialized partners, we carefully extrude the foamed PTFE as a dielectric to ensure maximum material quality and durability. This approach enables flexible production that is individually tailored to the specific requirements of our customers. In this way, GREMCO ensures that every HiVec cable meets the highest standards and is reliable in the long term.<\/p>\n<p>&nbsp;<\/p>\n<h2>HiVec &#8211; the future of high-frequency transmission<\/h2>\n<p>By using HiVec, GREMCO opens up new possibilities for high-frequency applications where speed, precision, and quality are crucial. The combination of foamed PTFE and high-quality inner conductor ensures low-loss and stable transmission &#8211; even at the highest frequencies. For demanding applications where every millisecond counts, HiVec is the optimal solution. We at GREMCO are proud to take a further step towards future-proof transmission technology with HiVec.<\/p>\n","protected":false},"excerpt":{"rendered":"In the world of high-frequency transmission, the choice of the right material is often the decisive factor for optimum signal quality.
