DATA AND COMMUNICATIONS CABLES - LiYY
These are special PVC data cables used for flexible use with free movement without tensile stress of forced movements in dry, moist and wet rooms but not suitable for open air, wherever the construction requirements call for a minimum outer diameter.
Standard : Based on VDE 0812
Voltage grade (not for power installation) : 0.14 mm² = 350 V; >/= 0.25 mm² = 500 V
Insulation Resistance : Min. 20 GΩ x cm
Temperature Range : Flexing -5°C to +70°C. Fixed installation -30°C to +70°C
Minimum Bending Radius : For flexible use 10 x cable ø
Test Voltage : Up to 0.25 mm² = 1200 V. From 0.34 mm² = 2000 V
Breakdown Voltage : Up to 0.25 mm² = 2400 V. From 0.34 mm² = 4000 V
