Communication cable symmetrical for digital transmission systems F/UTP tether

Cable contains single-wire current-conducting insulated copper conductors in a sheath of polymer material and a bearing element - steel cable (design in the form of a "figure eight"), located in a common sheath. Insulated conductors have different colour markings and are twisted into pairs. The number of pairs in the cable is from 1 to 4. Pairs are twisted into a core, over which a polyethylene terephthalate tape can be applied. On top of the twisted core the screen from metal-polymer tape (metal inside) or aluminium foil or metal tape is put. A copper or tinned copper wire is laid under the screen. An outer sheath of light-stabilised polyethylene (PE) is superimposed over the core and the supporting power element.
