Communication cable symmetrical for digital transmission systems F/UTP

Cable contains single-wire conductive copper cores, located in a sheath of polymer material. Insulated conductors have different colour markings and are twisted into pairs. The number of pairs in the cable is from 1 to 4. The 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. Copper or tinned copper wire is laid under the screen. Cable outer sheath is made of light-stabilised polyethylene (PE) or polyvinylchloride plasticate (PVC) or polyvinylchloride plasticate of reduced fire hazard with reduced smoke and gas emission (PVC LS), or of halogen-free polymer composition (ZH ng(A)-HF) or of polyvinyl chloride plasticate of reduced fire hazard with reduced smoke and gas emission and low toxicity of combustion products (PVC LS LTx).
