  • Quantum leap for digital cable
    cabletelevision transmission line with some added features, including superconducting circuits with zero electrical resistance and multitasking data bits that obe y the unusual rules of quantum physics. The cable might someday be used in computers that rely on quantum behavior to break codes, search
  • Guidelines for Setting Resistance Testing Thresholds
    Cable testers measure the resistance between all test points to determine if there are, or are not, connections. Cable testers are used to ensure that cable assemblies do not have OPENS or SHORTS.
  • Testing for Flame Resistance of Electrical Cables
    The National Fire Protection Agency (NFPA) publishes flame-resistance standards through its published National Electrical Code (NEC). Other agencies, such as UL and CSA also publish standards and also define certain tests for determining flame resistance (or lack thereof). Flame resistance
  • Out of the Frying Pan and Onto the Cable - Teflon (R) and other Fluoropolymers (.pdf)
    fluoropolymers possess special electrical properties and have a high resistance to solvents, acids and bases.These and other characteristics make fluoropolymers ideal materials used in the manufacture of wire and cable products.
  • Cable Testing Glossary
    The continuous electrical path between 2 or more points wherein current flows. This path has low resistance, usually less than 5 ohms. The path is constructed with metal parts, such as copper wire, contacts, terminations, splices, and mating contacts of connectors.
  • Wire & Cable Glossary
    is applied across one ohm of resistance. An ampere of current is produced by one coulomb of charge passing a point in one second.
  • The Importance of Oil Resistant Cables
    Everywhere, from the Renewable Energy Industry, Automotive Assembly Plants, to the factories that manufactures small office machines and even in some commercial buildings, the oil resistance of cables has become increasingly important. Oils serve a dual-purpose role in industrial applications, both
  • Expanded PTFE Polymer Keeps Electrical and Electronics Cables Clean and Flexible
    , but thin, light conductor insulation with a low dielectric constant, high dielectric withstanding voltage, and good tear resistance can help slim a cable's overall size and minimize flexural stress. ePTFE is one material
  • Medical Device Link .
    direct access to the company's expertise in designing and building custom cables. The questionnaire allows customers to specify their needs by means of a checklist that includes factors such as tension resistance, high-flex performance, chemical and thermal jacket durability, and desired or required
  • Chainflex Cables Available With Over-Molded Connectors
    Igus Inc., the leading developer of Energy Chain cable carriers, Chainflex continuous-flex cables and iglide plastic bearings, now offers Chainflex cables with over-molded connectors. , the leading developer of Energy Chain cable carriers, Chainflex continuous-flex cables and iglide plastic
  • North Hills Model DBT100A 1553 Network Tester User's Guide
    in the sequence S1-S5 for unambiguous pass/fail meaning. The five buttons are: S1. Stub-to-shield sort? - Go/No-go LED. This is a DC insulation resistance test. Any resistance between conductors and shield less than 50K Ohms will constitute a short-to-shield. It can also be used with the bus short
  • Detecting Circulating Currents and Hot Spots in Normally Non-current Carrying Conductors and Structural Members
    Often normally non-current carrying conductors, conduits, or even structural members contain circulating currents that are induced by currents flowing in adjacent conductors such as cable or bus. There is usually no way to measure the magnitude of these currents, and sometimes it is difficult
  • Receiving Inspection of Data Bus Couplers
    and observe results. Button 1 - go/no-go test. Checks for shorts between stub conductors and shield. Button 2 - measures the resistance of the stub cable and transformer winding. It should be between 1 and 5 ohm depending on the coupler. Button 3 - go/no-go test. Checks shorts between bus conductors
