Our Certificates

Standart: IEC 60 502-1

Description: Cu/Al conductors • XLPE insulation • PVC inner sheath • Armour Al wires • PVC sheath

Application:

These cables are designed for transfer and distribution of electrical power with nominal voltage U 0 / U 0 6/1 kV, frequency 50Hz and surroundings, which require non-proliferation of flames. 2XYRaY-FR and A2XYRaY-FR is used in power plants, industrial and switching installations, for street lighting, domestic power supply connections, in secondary distribution networks and other.These cables are preferentially used for underground application as well as for interior installation in room and cableducts and for outdoor and applications, for indoor installations, where greater mechanical protection an protection against accidental contact is required if damaged.
