Testing voltage between core and screening: 4 kV AC 5 min
Surrounding temperatures (fixed placement): - 30°C up to + 70°C
Surrounding temperatures (during installation): -5°C up to +50°C
Minimum bending radius (fixed placement): 10D
Basic characteristics:
Self-extinguishing PVC: EN 60332-1-2

The materials used do not contain any dangerous substances and fulfill the direction RoHS Nr. 2002/95/ES.
The cables can be placed in the environment with the explosion danger (zone 1, 2) providing compliances with the conditions of intrinsic safety according to 60079-11.
Usage:
The power cables with copper screening are used mainly in distribution points of high voltage and very high voltage, for connecting in systems where the resistance to interference (EMC) is required, in the circuits of pulsed supply with frequency converters and everywhere that higher requirement against penetration or radiation of interfering signals is demanded. It is possible to use them in dry or wet environment and for placement into the soil.
The cables can be placed in the environment with the explosion danger (zone 1, 2) providing compliances with the conditions of intrinsic safety according to 60079-11.
The most common derived variants:
1-CYKY – power cable from PVC without screening
