The materials used do not contain any dangerous substances and fulfill the direction RoHS Nr. 2002/95/ES.



The cable is used for transmission of analog and digital signals in inner telecommunication installations.

Electrostatic screening ensures the protection against electrical interference. It is possible to use them in the dry or wet environment and for outdoor installation on building walls and under a plaster as well.

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:

JCYFY /st/ – with separately screened elements


Note: the element can be a core, a pair, a triad or a quad; then the standard colour marking is:

- HD 308 S2 for a core variant

- couples with black and white core – numbered

- trios with black, white and dark red core – numbered

- quads with black, white, dark red and brown - numbered


The product is conformable with the direction EU 73/023/EEC for low voltage.
