PRESENTATION

These are used in intercommunication cables.

REFERENCE STANDARDS

K35 OVE (Austria)

CABLE STRUCTURE

1- Conductors :
Conductors consist of solid copper having a diameter of 0.6 mm for YYSCH cables and 0.8 mm for YR cables.

2- Insulation of conductors :
Conductors are insulated by PVC insulating layer covered complying with the Austrian standards OVE K50. The thickness of insulation is such as the electrical requirements are met.

3- Stranding :
Stranding is concentric for combinations having more than 5 cores. Wires are assembled in parallel for small combinations.

4- Outer sheath
Outer sheath consists of unleaded PVC.
It may be grey RAL 7035 or ivory RAL 1013 for YYSCH cables and white RAL 9016 for YR cables.
