APPLICATIONS

LY and LYc are power flexible single wires intended for interconnection in electrical equipment. Wires can be applied in control cabinets, electronic equipment and others. They are also used in lighting devices and systems.

CONSTRUCTION

- multiwire conductors, stranded of bare annealed copper wires (tin-plated on request), meeting requirements of class 2 per PN-EN 60228,

- PVC insulation - LY wires,

- heat resistant PVC insulation (PVC 90°C) - LYc wires,

- identification colour code in accordance with PN-87/E-90050.

AVAILABLE UPON REQUEST

LYc 105°C - wires with heat resistant PVC insulation up to 105°C.

LY-LSF  - wires with special LSF PVC insulation. LSF PVC is self-extinguishing and flame retardant with low emission of toxic and corrosive fumes.

H05V-R and H07V-R - wires made of according to PN-EN-50525-2-31 standard.
