Low-voltage power cables rated 0.6/1 kV, conforming to ČSN 34 7659, HD 603, and IEC 60502-1, designed for permanent installations in buildings, power stations, open air, underground, and in trays or ducts where mechanical damage is unlikely. These cables use aluminum (1-AYKY) or copper (1-CYKY) conductors per EN 60228, available in solid (Class 1 RE/SE) or stranded (Class 2 RM/SM) forms. They feature PVC insulation (HD 603 color code), EPDM or plastic tape fillers, and a black PVC sheath. Offered in configurations from 2 to 5 conductors, including 3+1 and 4+1, with sizes from 1.5 mm² to 300 mm². Suitable for temperatures from -50 °C to +50 °C, with a max conductor temperature of +70 °C and a short-circuit threshold of 160 °C. The cable maintains a bending radius of 12D, installs at ≥5 °C, operates at 50 Hz, and is tested at 4 kV. Fire-rated to EN 60332-1-2, these cables deliver dependable performance across varied power distribution setups.
