Four 6 mm² class 5 copper cores — three phases and a neutral — at 84 strands of 0.30 mm each, PVC insulated and sheathed to 300/500 V. 41 A with three conductors loaded on reference method C, which is about 28 kVA on a 400 V three-phase supply. 3.30 Ω/km, roughly 213 kg of copper per kilometre of cable. Drawn on the Pilone line in Lahore.

Check the coil before you pay for it
Every coil leaves our factory with a QR code printed on the packaging. Scan it and the factory record for that batch opens: brand, cable size, batch number, year of manufacture and conductor. Compare the batch number on screen with the one printed on your coil — if the two do not match, it did not come from us.

Four cores carry three phases plus a neutral, so this is a three-phase cable, not a bigger version of the household flex. The people buying 6mm 4 core cable in the flexible build are generator installers running a tail from a set to the changeover panel, borewell fitters whose cable goes down the bore and comes back up with the pump, and site contractors feeding mixers and welding plants that shift as the work moves. At 41 A with three cores loaded it covers about 28 kVA at 400 V — the small-to-mid genset and light-machinery band. Above that, step up to 10mm 4 core flexible cable at 57 A.
The flexible run between a portable or skid-mounted set and the changeover panel, up to about 28 kVA on a 400 V supply.
Borewell and submersible sets, where the cable is pulled up and dropped back every time the pump comes out.
Mixers, hoists and welding plants that get dragged to a new corner of the plot as the work moves.
Size it on current per phase, not on the set's badge. A 15 kVA generator on a 400 V three-phase supply delivers 15000 ÷ (1.732 × 400) = 22 A per phase, roughly half what this cable is tabulated for. On a 12 m tail that current drops 22 × 12 × 7.3 ÷ 1000 = 1.9 V, or 0.5% of 400 V. Load the cable to its full 41 A and the drop reaches the 5% BS 7671 allows on a power circuit — 20 V of 400 V — at about 67 m: 20000 ÷ (41 × 7.3) = 66.8. Flexible cable is also usually bought on a drum and left partly coiled, and a coiled cable under load carries less than the table says, because the heat has nowhere to go. Pay the tail out flat before you run the set.
