YYSCH & YR
PRESENTATION
These are used in intercommunication cables.
REFERENCE STANDARDS
K50 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.
