Today’s cable systems are increasingly digital. Armed with a rank of receivers, multiplexers and remultiplexers, a headend can produce hundreds of channels for delivery to viewers. Photo courtesy ...

From its origin as Community Antenna TV (CATV), a solution to poor over-the-air reception in the late 1940s, cable distribution is now the dominant delivery method for all TV programming. Even with ...

Researchers in Spain have developed the most advanced and powerful conductivity cable in the world. This prototype measures 30 metres and was made using superconducting material. The new cable ...

When we were kids, overhead power cables were a constant fixture in the neighborhood. Not only were they the bane of our kites, but they also had a tendency to fail during storms leaving us in the ...

MR. S. W. MELSOM, of the staff of the Cable Makers' Association, has contributed a paper on the standardization of cables and equipment, with the object of reducing distribution costs, to the ...

Line skill technicians prepare the infrastructure for assessment by isolating the spans and connecting the assessment equipment. A 50/60-Hz overvoltage is applied to the cable system for approximately ...

The measurement engineer can view the values from tan δ and partial-discharge testing directly in the cable test van. Clear representation helps to detect severe defects or locate partial discharges ...

Audio cables installed exposed on the surface of ceilings and sidewalls shall be supported in such a manner that they will not be damaged by normal building use. Cables shall be secured by _____ ...

For all their energy savings and control benefits, when VFDs fail, they bring motor-driven industrial operations to a dead stop. To avoid such situations, savvy engineers ensure drive-system ...

Researchers at Spain’s Universitat Autònoma de Barcelona, ICMAB-CSIC, and Spanish firms Labein Tecnalia and Nexans, and Endesa, have constructed a 30-meter superconducting electric cable that they say ...
