内屏蔽铁路数字信号电缆
Inner Shielded Railway Data Signal Cable

  

 

 

产品特点及用途 Character & Usage

本产品在 “铁路数字信号电缆”的基础上,对传输四线组进行了单独屏蔽(分A型、B型,结构见电缆组序排列示意图),因而提高了电缆近端串音衰减,有效解决了在同根电缆内传输相同频率的铁路信号信息时,各传输线组之间的干扰防卫问题。可用于信号系统及设备之间,同缆传输同数量级电平的同频信息及最高2Mbit/s数字信息,以及传输交流750V或直流1100V电力的性能。

On the basis of Railway Digital Signaling Cable ,the quads are shielded individually(A Type,B Type , See Structure section picture ) ,hence near-end cross-talk attemuation is increased,effectively solve the problem of interference and guard between transmission-wire groups when same frequency railway signal or message are transmited in one piece cable.It is able to be applied to transmite same frequency information in same quantity level and digital information up to 2Mbit/s,and AC 750 or DC1100V power energy.

本产品适用于铁路信号自动闭塞,计轴、车站电码化、微机联锁、微机监测、调度集中、 调度监督、大功率电动转辙机等有关信号控制装置和设备之间传输控制信息,监测信息和电能,可做为DMIS底层系统数字信息和业务电话的传输通道。当用于ZPW-2000、 UM71无绝缘轨道电路自闭系统时,传输距离可达10Km。并可代替“铁路信号电缆(PT缆)用于其它铁路信号系统中。

The cable is applied in automatic block system,and to transmite controlling signals,monitoring information and electric energy among signalling equipment and control device in axle counter, track circuit Coded in station, Microcomputer Railway Signal Interlocking System,Computer Supervisory System, centralized traffic control (CTC), centralized traffic supervision,high power switch and lock movement.It is also able to be used as transport channel of DMIS primary information,service call and area communication.
When the cable is used for signalling of the ZPW—2000, UM71 uninsulated Track Circuit (Jointless Track Circuit) automatic block system,and may satisfy 10KM distance request.And replace "railway signaling cable (PT Cable)" in others Railway signal system.

铁路内屏蔽数字信号电缆除基本型外还有阻燃型、防白蚁型、耐寒型、高屏蔽型等用于特殊环境的产品。 在电缆制造工艺方面,新技术条件规定,绝缘导电线芯采用具有国际先进水平的皮-泡-皮物理发泡三层共挤技术。另外电缆主要原材料和选用也与IEC等国际标准规定基本一致。

Railway digital signaling Cable have not only nomal type,but also the types used in special environment, such as flame retadant type,anti-termite type,high moisture proof type, high shielding type,etc.
In manufacturing technique,the cable main material adopted comply with IEC Standards.What's more,Skin-foam-skin physical foaming triple extrusion technology are adopted to manufactur insulated cores.

使用特性 Operating Characteristics:
1、电缆导体长期工作温度不超过70℃;
2、电缆使用环境温度为-40℃~60℃;
3、电缆敷设时的弯曲半径应不小于电缆外径的20倍;
4、电缆敷设时的环境温度应不低于-10℃。
