APPLICATIONS

TECHNOFLEKS LiYYCY-Nr 300/500 V and TECHNOFLEKS LiYYCYżo-Nr 300/500 V are flexible, overall shielded cables designed for wet or dry locations and intended for control, protection and monitoring systems or power supply, all in power engineering. The cables are also intended for wiring industrial plants, such as production lines, air-conditioning equipment etc.

The overall shield protects the cables against external electromagnetic interferences and prevents emission of interferences produced in the cables.

Cable inner sheath offers enhanced protection against mechanical damage.

The cables are designed to offer high flexibility combined with tensile strength.

The cables are suitable for indoor installations connecting fixed and movable equipment.

Cable outer sheath is oil-resistant.

CONSTRUCTION

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

- black PVC insulation and white conductor numbers printed on it for identification, additional green-yellow protective conductor in TECHNOFLEKS LiYYCYżo-Nr 300/500 V cable,

- insulated conductors laid-up in layers, green-yellow protective conductor located in the outer layer in TECHNOFLEKS LiYYCYżo-Nr 300/500 V cable,

- inner PVC sheath,

- tinned copper wire braid shield of effective density coverage,

- PVC cable sheath, grey RAL 7001, other colours also available.
