1. An elevator system comprising:
an elevator car comprising one or more service appliances;
a hoistway in which the elevator car moves;
a feed source and a fluid source associated to a hoistway wall;
a travelling cable connected to the elevator car and to the hoistway wall, wherein the travelling cable comprises
an electric conductor and/or a data carrier operatively connected at a first end to the feed source and at a second end to the service appliances of the elevator car,
a protective layer comprising an outer diameter and surrounding the electric conductor and/or data carrier, and
a duct connected at a first open end to the fluid source and at a second openable end to the elevator car;
a sensor system configured for detecting a swaying amplitude of the travelling cable and comprising a sensing tool included into the travelling cable and operatively connected to an optical equipment associated to the elevator car or the hoistway wall; and
a microprocessor associated to the sensor system and to the fluid source, the microprocessor being configured for receiving swaying amplitude data from the sensor system and for operating the fluid source when the swaying amplitude exceeds a predetermined threshold.
