HYAC Figure 8 Aerial Cable
Product application:
It is mainly used for audio and video communication within the General Administration of Telecommunications and between exchanges and users. It is also used as an audio connection between other communication devices. It supports the connection of voice, digital phone and fax devices. It is the branch and main line of telecommunications cabling system.
Standards:
ANSI/ICEA S-84-608 ANSI/ICEA S-85-625 CSN IEC 708-1 YD/T 322
Product features:
·Compliant with YD/T 322 performance standards, suitable for outdoor voice backbone connections, with good mechanical and environmental performance;
·The insulated wire adopts standard chromatography, and the lay length of each pair is set ·reasonably, which is easy to distinguish and maintain during construction;
