Standart: VDE 0815

Description: PVC insulation • pairs stranded in layers • static screen • sheath of PVC

Application:

These cables are used for installation of equipment of telephone stations. They are suitable for fixed indoor installation and for external walls of buildings. The screen of metal foil protects the cable from external electrical interferences. The use of these cables for power installations and underground installation is not permitted.

Features:
Color coding
Number of pairs.
The pairs are counted successively commencing at the outside and counting inwards in the same manner throught all layers
