Latin America. Responding to the demand of integrators, the American manufacturer Belden continues to release new cables for sound. An example is the new anti-humidity cables, required in coastal projects, also when we use pipes that can flood.
An example of such cases is when an installer requires a 14-gauge for the new hotel's horns, but fears that moisture will quickly oxidize its copper conductors. That's why Belden introduced the 5100U1 model. This cable has double protection against water: it uses tinned copper conductors (copper for conductivity, stane for insulation) and keeps an absorbent tape under the lining that inflates like a honeycomb if the water were to enter).
Another new family is the "superflex" range. There are times when the installer demands horn cable with more wires than usual. The Belden commercial series has between 7 and 19 threads, while the "superflex" has 42 and 65 threads per conductor. To follow the same example, a 5100UE cable would be a commercial type 14 gauge, while the 5100UP model would be a superflexible type 14 gauge. The flexibility of the cable gives two advantages to the installer: greater radius of curvature (we can twist the cable in difficult accesses) and greater pulling force (when we do not have registration boxes at regular distances, we can throw the cable with much greater force without fear of mistreating it).
As a third novelty, Belden launched the "Class 1" series. This category of speaker cable is mandatory when the voltage is triggered up to 600v. To avoid risks, the NEC code advises using special cables that support this high voltage. A 14 caliber would be the 8814, which is UL certified to handle 600V RMS safely.
