Inside it is provided with secondary shielding layer.
In a preferred embodiment of the invention, described RS485 communication cable includes a pair mutually stranded RS485 and leads to
Letter core and be coated on the first restrictive coating that the pair of RS485 communicates outside core, described first restrictive coating with the pair of
It is provided with the first packed layer between RS485 communication core, the inwall of described first restrictive coating is provided with described first screen layer；
Described RS232 communication cable includes a pair mutually stranded RS232 communication core and is coated on the pair of
The second restrictive coating that RS232 communicates outside core, described second restrictive coating is communicated with the pair of RS232 and is provided with the between core
Two packed layers, are provided with described secondary shielding layer in the inwall of described second restrictive coating；
The direction of lay of the direction of lay of the pair of RS485 communication core and the pair of RS232 communication core is contrary.
In a preferred embodiment of the invention, described first screen layer and secondary shielding layer are tinned copper wire braiding
The screen layer becoming, the screen layer periphery being woven in described tinned copper wire is coated with foil shielding layer.
In a preferred embodiment of the invention, described cable core includes video line, control line and power line.
Due to employing technical scheme as above, by RS485 communication cable and RS232 communication cable is integrated sets for the present invention
Put in elevator cable, decrease number of cables in hoistway it is ensured that the normal operation of elevator.In addition, RS485 communication cable and
The direction of lay of RS232 communication cable can not only ensure the bending resistance of elevator cable on the contrary moreover it is possible to prevent by screen layer
Only the signal interference between cable core is normally carried out it is ensured that communicating.
