Telephone cable: HPVVHYAHYV what's the difference between the three phone cables? Which is better?
Details of HPVV: HYV (local telecommunication cables are widely used in the communication network construction in metropolitan area network, and to install overhead pipeline, the main transmission of audio signal (HYAT) filling type communication cable used in communication network construction in metropolitan area network, with the installation of pipeline, a water blocking effect, without inflation protection, the main transmission of audio signal) HYAC self-supporting communication cable (for use in the construction of communication network in metropolitan area network, overhead installation, convenient construction, the main transmission of audio signal) HYAT53 filling type armoured cable (used in the complex environment of communication network construction of metropolitan area network, buried underground, water blocking, anti rodent effect, without inflation protection
Under certain conditions, it can also be used to transmit more than 2048kbit/s digital signals. The utility model is suitable for overhead or pipe laying lines in cities, suburbs and local areas, and can also be buried directly.
HYA and HYAT have been replaced by better moisture resistance. HYA is a copper core, solid polyolefin insulation, moisture barrier, PE sheath and local communication cable. It is mainly used for HYA cable, [1] transmission, audio, 150kHZ and analog signals below, and 2048kbit/s and below digital signals.
