Application

These cables are suitable for telephone stations and sub-extensions, for signal and data trans-mission. This cable type with electrostatic screening (St) protects the transmission circuits against extern electrical interferences. Installation cables laid up in pairs are preferably used for indoor telecommunication installation in dry and damp places, but also in the open for fixed installation on outer walls of buildings. The use of this cable is not allowed in energetic purposes.

Construction

• Bare copper conductor, solid, 0,6 and 0,8mm Ø according DIN VDE 0295
