The speed(S) of electromagnetic waves propagating This analysis of the performance related to dielectric mediums through a dielectric medium is given by: with respect to: Dielectric losses and its effect upon cable properties, dielectrics versus characteristic impedance, and the attenuation in the coaxial line for different dielectrics.

We’ve tried to simplify the decision-making process as to which cables to choose for what installation, taking into account factors such as performance over distance, preventing RF interference and fire/safety codes. We also want to introduce you to some products that may ease some of your installation headaches, such as BrightWire® anti-corrosion treatment for braid shields, and QR® 320, an ultra-long-reach coaxial cable. One of the big changes in our industry is the introduction of powered broadband services, which are addressed in the National Electrical Code’s Article 830. This manual shows you when to use NEC 830 cables; pages 13 and 16 (aerial and buried installations) cover specific issues involving installation clearances; other chapters carry special callouts concerning NEC 830 issues. Most attention is paid to residential installations (page 22) which has the most “practical” information, especially for trim-out.

  • Wiring a Wall Section
    Youth Explore Trades Skills Electrician Wiring a Wall Section Description The activities that have led up to wiring a wall should have given students the skills and knowledge to culminate with this activity. This activity could be an opportunity to conduct a summative assessment of students’ previous knowledge of theory, safety, code, and wiring methods. Wiring a wall section will introduce students to a few new CEC rules and wiring methods. Having a wall section is obviously a requirement for this activity. The wall section could be full scale or smaller; to make this activity relate to the real world, it’s recommended that the wall section be at least 4' wide by 4' tall. The wall section shown in Figure 1 would be optimal, as it has some real (although scaled down to half size) features such as door and window openings, as well as a corner section, which will help students learn about routing wire and placement of device boxes in relation to these features. Figure 1—Sample wall section Building a wall section for a class requires a substantial amount of lumber and time. Optimally, this activity would work well with students having completed the carpentry portion of the course first. This activity is an opportunity for students to wire a wall to code specifications and with the teacher’s supervision, energize and test their circuits. Students will likely work in small groups, depending on the availability of material and the number of walls available. The students should have the opportunity to wire their wall sections individually, to give the teacher a clear picture of each student’s skills and competencies.

Many cord and cable applications are subject to one or more of the following conditions: • Impact & Vibration • Oil, chemical & water deterioration • Crushing & Abrasion • Extreme heat & cold • Pulling & Flexing • Unsafe areas Too often, maintenance must use ORDINARY cord and cable in these areas because that’s all that’s available. These products do not hold up because they are not designed for maintenance environments. As you know . the real cost of cord and cable maintenance includes not only the cost of material, but also the labor and downtime that result from unnecessary repair and replacement of damaged or worn-out cord and cable. 2 TPC WIRE & CABLE TPC WIRE & CABLE TPC WIRE & CABLE Ideal for Abusive Environments Abrasion • High Heat • Chemical In the mining environment, it is important to address the abusive environments in which the electrical cable is applied.

It means sharing information or services between local devices such as other computers, printers, external hard drives and even video distribution. It also means sharing information or services with the rest of the world via the Internet. The network highway can be wired or wireless creating enormous flexibility. In this discussion we're going to focus on the wired side, otherwise known as Ethernet cabling and connectivity. Before we get started let’s keep in mind that this is a practical guide. Many of the deeper details are omitted and more relevant to an engineering specification. So get ready, here comes the fine print… Disclaimer: Nothing in this guide should be construed as specific advice or recommendation of any kind. Your application will ultimately determine the best possible solutions. Warehouse Cables is in no way responsible for any interpretation or results thereof from the information provided herein. Bring In the Standards Ok, so who came up with this Ethernet communications scheme? The Institute of Electrical and Electronics Engineers (IEEE) published the final IEEE 802.3 standard in 1985 as a replacement for older wired LAN (local area network) technologies. The twisted pair cabling standard arrived around 1990 and has since evolved through the various “Categories” up to the present. In addition, the Telecommunications Industry Association and Electronic Industries Alliance (EIA/TIA) developed their own standards, based on IEEE 802.3 to serve the public interest by eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and promoting the improvement of products.

  • Coaxial Cable
    ANALOG ELECTRICAL and DIGITAL VIDEO FORMATS and CONNECTORS Analog Electrical Formats/Connectors Component Video Component video is a type of video information that is transmitted or stored as two or more separate signals (as opposed to composite video, such as NTSC or PAL, which is a single signal). Most component video systems are variations of the red, green and blue signals that make up a television image. The simplest type, RGB, consists of the three discrete red, green and blue signals sent down three wires. This type is commonly used in Europe through SCART connectors. Outside Europe, it is generally used for computer monitors, but rarely for TV-type applications. Another type consists of R-Y, B-Y and Y, delivered the same way. This is the signal type that is usually meant when people talk of component video today. Y is the luminance channel, B-Y (also called U or Cb) is the blue component minus the luminance information, and R-Y (also called V or Cr) is the red component minus the luminance information. Variants of this format include YUV, YCbCr, YPbPr and YIQ. In component systems, the synchronization pulses can either be transmitted in one or usually two separate wires, or embedded in the blanking period of one or all of the components. In computing, the common standard is for two extra wires to carry the horizontal and vertical components, whereas in video applications it is more usual to embed the sync signal in the green or Y component. The former is known as sync-on-green.

  • TIPS on a SUCCESSFUL HDMI OVER CAT5/6/7 INSTALLATION By
    TIPS ON A SUCCESSFUL HDMI OVER CAT5/6/7 INSTALLATION By HDTV SUPPLY, INC. (800) 841-9238 (805) 277-1870 Direct WEB: www.HDTVSupply.com SUPPORT: [email protected] Today when I Googled the term – HDMI problem – I came up with 28,700,000 pages with 10 links on each page making for over a quarter of a BILLION posts by individuals who were looking for solutions to their unique HDMI problem….again a quarter of a BILLION. Why? HDMI is not like the older plug-and-play analog VGA, component, composite or s-video technologies as it digital and encompasses a host of handshakes and synchonization along with EDID display information signals that weren’t in analog. There isn’t even a video wire or an audio wire in a 19 wire HDMI cable as it is all digitized together. Many of the reported problems are about sending HDMI over long distances and not getting video or audio or having video but it has sparkles within the picture. The cause could be any one of a dozen plus problems but typically there are: 1. The HDMI cable is too long given the 1080p resolution being send and wire gauge. 2. The HDMI cable internal wires are too small. 3. The capacitance in the long HDMI cable impacts the resolution, like 1080p, being sent. 4. The HDMI source devices HDMI output doesn’t have enough voltage and current to drive a long HDMI cable. PC’s are notorius for that as ther video card designer thought his card would be used with only a 3 or 6 foot HDMI cable.
