通信電纜是傳輸電氣信息用的電纜。按其用途分為市內(nèi)電話電纜、長途通信電纜、局內(nèi)配線架到機(jī)架或機(jī)架之間的連接的局用電纜、用作電話設(shè)備連接線的電話軟線、綜合通信電纜、共用天線電視電纜、射頻電纜及光纜。用于電話通信線路、綜合布線系統(tǒng)、電纜電視系統(tǒng)。
Communication cables are cables used for transmitting electrical information. According to their purposes, they are divided into local telephone cables, long-distance communication cables, office cables for connecting distribution frames to racks or between racks, telephone flexible cords used as connection lines for telephone equipment, comprehensive communication cables, shared antenna television cables, RF cables, and optical cables. Used for telephone communication lines, comprehensive cabling systems, and cable television systems.
本部分主要論述建筑物內(nèi)常用市內(nèi)電話電纜。室內(nèi)常用電話電纜主要有兩類:HYA型綜合護(hù)層塑料絕緣市內(nèi)電話電纜和HPVV銅芯全聚氯乙烯配線電纜。
This section mainly discusses the commonly used local telephone cables in buildings. There are two main types of commonly used indoor telephone cables: HYA type comprehensive protective layer plastic insulated urban telephone cables and HPVV copper core fully polyvinyl chloride wiring cables.
HYA型綜合護(hù)層塑料絕緣市內(nèi)電話電纜可在室外直埋或穿管敷設(shè)。室內(nèi)可架空或沿墻敷設(shè)。
The HYA type comprehensive protective layer plastic insulated urban telephone cable can be directly buried outdoors or laid through pipes. Indoor can be elevated or laid along the wall.
HPVV銅芯全聚氯乙烯配線電纜為室內(nèi)使用的電纜可穿管或沿墻敷設(shè)。
HPVV copper core PVC wiring cable is an indoor cable that can be threaded through pipes or laid along walls.
