Title: MONITORING SYSTEM SIGNAL TRANSMISSION COMPOSITE CABLE
Abstract:
A monitoring system signal transmission composite cable comprises a power cable (1) and a twisted-pair unit (2). The twisted-pair unit (2) comprises at least two twisted-pair cables (21, 22). A twisted-pair cable (21) in the twisted-pair unit (2) is connected to the power cable (1) through a tearing strip (521). The adjacent two twisted-pair cables (21, 22) in the twisted-pair unit (2) are connected through a tearing strip (522). The twisted-pair cables (21, 22) in the twisted-pair unit (2) are provided with at least one shielding layer (53) with longitudinally applied aluminum-plastic strip on two sides. One monitoring system signal transmission composite cable can be divided into multiple cables, and is equipped with a power line; therefore, cables do not need to be laid multiple times during mounting, use is very convenient, and time and cost are saved. Meanwhile, a double shielding effect of the longitudinally applied aluminum-plastic strip at the dual faces strengthens shielding, improves and enhances a shielding capability of a monitoring system against electromagnetic interference, prevents an electromagnetic interference wave from affecting a closed circuit in the monitoring system and implements functions of electromagnetic interference prevention and electromagnetic radiation defense.
