Communication and Power Cables
Communication cable
- Types : shielding cable
- Cross section : 1.0~1.5mm
2
- Maximum allowable temperature: 60°C
- Maximum allowable cable length: under 300m
Remote control cable
- Types : 3-core cable
Central control cable
Separation of communication and power cables
- If communication and power cables are run alongside each other then there is a strong likeli-
hood of operational faults developing due to interference in the signal wiring caused by electro-
static and electromagnetic coupling.
The tables below indicates our recommendation as to appropriate spacing of communication
and power cables where these are to be run side by side
NOTE
!
• The figures are based on assumed length of parallel cabling up to 100m. For length in ex-
cess of 100m the figures will have to be recalculated in direct proportion to the additional
length of cable involved.
• If the power supply waveform continues to exhibit some distortion the recommended
spacing in the table should be increased.
- If the cable are laid inside conduits then the following point must also be taken into ac-
count when grouping various cable together for introduction into the conduits
- Power cable(including power supply to air conditioner) and communication cables
must not be laid inside the same
- In the same way, when grouping the power wires and communication cables should not
be bunched together.
