PTL Cable announces the official launch of its Air Dielectric Cable production line.
Air dielectric cable uses air as the primary insulation medium between inner and outer conductors, supported by spiral insulation. Since the dielectric constant of air is close to 1, the cable offers ultra-low attenuation, high power capacity, excellent moisture resistance, and stable phase performance.
Key applications include broadcast TV transmitters, satellite ground stations, and long-distance trunk transmission systems.
This new product complements PTL's corrugated copper tube, corrugated aluminum tube, and seamless aluminum tube TRUNK CABLE series, providing customers with a more complete range of low-loss transmission solutions.
