TECHNOFLEX 2YSLCYn-J and TECHNOFLEX 2YSLCYnK-J  shielded cables are intended for connecting converters or inverters with motors in industrial installations, production plants, air-conditioners and other equipment operating in dry and wet locations.

Cables are protected by a specially designed and highly effective collective shield against emission of electromagnetic interferences to environment and against influence of external interferences.

TECHNOFLEX 2YSLCYn-J cables are suitable for indoor and TECHNOFLEX 2YSLCYnK-J cables for outdoor fixed and movable installations.

Sheathing PVC of high oxygen index is self-extinguishing and flame retardant. The cables pass combustibility test according to PN-EN 60332-3 standard.


- flexible, multiwire conductors, stranded of bare annealed copper wires (tin-plated on request), meeting requirements of class 5 per PN-EN 60228,

- polyethylene (PE) insulation - black, blue, brown and green-yellow,

- insulated conductors laid-up in a cable core,

- double screen of aluminium laminated tape and braid of tinned copper wire, braid shield of coverage bigger than 80%,

- PVC cable sheath of TECHNOFLEX 2YSLCYn-J cable, grey RAL 7001, other colours also available,

- PVC cable sheath of TECHNOFLEX 2YSLCYnK-J cable, black RAL 9005, other colours also available.


TECHNOFLEX 2YSLCH-J - halogen free cables, applied when higher safety in case of fire is required. The cables are flame retardant, their smoke emission in fire is low and released gases are not corrosive.
