Single conductor is a term which refers to the cable design used to connect the inspection camera and accessories to the control system. The central core of single conductor cable is constructed by wrapping copper strands around a single stranded insulated wire. A plastic jacket is then extruded over this coaxial cable and two layers of galvanized steel wire are Contra-Helically wrapped for strength and protection of the coaxial cable. These galvanized wires are also used as a safety ground for the system.
This produces a 1/4 cable with amazing breaking strength that is capable of transmitting equipment power, multiple camera video signals and equipment control signals simultaneously. This allows us to supply power to the camera, tractor and lights and control the equipment functions, like pan & tilt, tractor speed selection, stop, freewheel and many more, at the same time as transmitting multiple video signals to the control unit.
Unlike Multi Conductor, the video signal quality is not affected by the length of cable. The video signal is modulated at the camera and sent to the controller. Then the controller demodulates the signal and reproduces the original high quality image that is seen on the monitor and recorded.
Because safety is important, we want you to know that the 80-120 volts needed to perform these functions are applied only to the center conductor wire. For the operator to come in contact with the voltage three metallic layers and two insulation layers would have to be severed. With Multi Conductor the only protection is the plastic like outer jacket and the individual wire insulation.
This makes single conductor cable extremely safe to use and is the reason it is approved for use in hazardous locations.
