Communication cables OS Armoured LC Fire retardant

Applications

These cables are used for telecommunication and DCS Data highway for OSP telephone communication and Public Address System. They are well adapted to underground use in industrial applications, in moist areas, where hydrocarbon and mechanical protections are needed. The lead cover brings an enhanced resistance to aromatics hydrocarbons.
