TECHNOFLEX 3Plus 2YSLCY-J and TECHNOFLEX 3Plus 2YSLCYK-J shielded cables with symmetrical construction 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.

The division of the protective conductor into 3 evenly distributed in the cable core (on the circumference of 120°) enabled to achieve a symmetrical distribution of fields and reduce the emission of electromagnetic interference into the environment in relation to the cables with four conductors.

TECHNOFLEX 3Plus 2YSLCY-J cables are suitable for indoor and TECHNOFLEX 3Plus 2YSLCYK-J cables for outdoor fixed and movable installations.

Cable outer sheath is oil-resistant.


- 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 (protective conductor divided into 3 wires in a green-yellow),

- insulated conductors laid-up in a cable core, construction 3+3,

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

- PVC cable sheath of TECHNOFLEX 3Plus 2YSLCY-J cable, transparent or grey RAL 7001, other colours also available,

- PVC cable sheath of TECHNOFLEX 3Plus 2YSLCYK-J cable, black RAL 9005, other colours also available.


TECHNOFLEX 3Plus 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.
