Character & Usage
|
|
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.
|
|
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.
|
|
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.

Operating
Characteristics:
1.1 Conductor of cable operating temperature should not higher
than 70 deg.
1.2 the operating temperature should not between -40 deg.and
+60deg.
1.3 Bending radius of installation should not less than 20 times of
outer diamenter of cable.
1.4 Installation ambient termperature should not
lower than -10 deg.
1.5 the cable has high mechanic strength, corrosion
-proof , high-impact strength and cold resistance .
1.6 The group of screened
cores have good shielding properties ,which can enhance the ability of the
groups to oppose disturbance
