APPLICATIONS

TECHNOFLEKS LiY11Y-Nr 300/500 V and TECHNOFLEKS LiY11Yżo-Nr 300/500 V are flexible 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.

Polyurethane sheath offers enhanced protection against mechanical damage, particularly to abrasion and tear, also resistant to oils, petrol, bacteria and ultraviolet radiation.

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

Cables are dedicated to work in heavy duty conditions.

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

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 LiY11Yżo-Nr 300/500 V cable,

- insulated conductors laid-up in layers, green-yellow protective conductor located in the outer layer in TECHNOFLEKS LiY11Yżo-Nr 300/500 V cable,

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