Communication cable symmetrical for digital

Cable contains single-wire conductive copper cores, located in a sheath of polymer material with different colour markings and twisted into pairs. The number of pairs is from 1 to 8. The pairs are twisted into a core, over which a polyethylene terephthalate tape can be applied.

A screen made of metal-polymer foil or aluminium foil or metal tape is laid on top of the twisted core. A contact wire is laid under the screen. Cable outer sheath is made of light-stabilised polyethylene or polyvinylchloride plasticate, or polyvinylchloride plasticate of reduced fire hazard with reduced smoke and gas emission, or halogen-free polymer composition, or polyvinylchloride plasticate of reduced fire hazard with reduced smoke and gas emission and low toxicity of combustion products.

The outer sheath of the cable does not spread combustion in single or group laying.
