Three 10mm² class 5 cores in one sheath — three phases to a machine that gets moved, or live, neutral and earth to heavy single-phase gear dropped down a borewell and dragged across a yard. 80 strands of 0.40 mm per core is what lets it bend all day without work-hardening. 57 A on method C with all three cores loaded as phases; give the third core to earth and only two are loaded, so the same cable is good for 63 A. 1.91 Ω/km, 4.4 mV/A/m, 300/500 V. 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.
10mm 3 core flexible cable is quoted at the day's copper rate, per metre.
10 mm² 3 core flexible cable is quoted at the day's copper rate, per metre — send the metres and your city on WhatsApp and today's number comes back. Which rating applies depends on the circuit: line, neutral and earth loads two conductors and the cable carries 63 A on BS 7671 reference method C at 30°C, about 13.9 kVA at 220 V; three phases with no neutral loads all three and the figure is 57 A, about 39.5 kVA at 400 V. The class 5 conductor is 80 strands of 0.40 mm, which is what lets the cable be coiled between jobs.
Most people arriving at a 10mm 3 core cable price in Pakistan are comparing quotes that are not comparable. A bare figure with no unit, a per-foot rate that flatters itself because a foot is under a third of a metre, a coil price with no metre count attached. Reduce all of them to a rate per metre before you decide, and state “flexible” rather than just the size, because the standard build is a different cable.
| Quoted as | Length in metres | To get the per-metre rate |
|---|---|---|
| Per metre | 1 m | Nothing to do |
| Per foot | 0.305 m | Multiply the per-foot rate by 3.281 |
| Per yard | 0.914 m | Multiply the per-yard rate by 1.094 |
| Per 90 m coil | 90 m (295 ft) | Divide the coil price by 90 |
| Per 45 m half coil | 45 m (148 ft) | Divide by 45 |
| Per 100 m drum | 100 m (328 ft) | Divide by 100 |
Coil lengths are not standardised in Pakistan, so a coil is a container rather than a quantity. Get the metre count onto the invoice before you pay. We quote per metre against the length you give us. The price per meter page covers every conversion, and how cable is priced in Pakistan explains what moves the number.
63 A with two conductors loaded, 57 A with three. The size ladder below is the useful context: each step up buys current, and buys back run length as the voltage drop per amp-metre falls.
| Size | Strands (class 5) | 2 loaded | 3 loaded | Voltage drop | Copper in a 90 m coil |
|---|---|---|---|---|---|
| 4 mm² | 56/0.30 | 36 A | 32 A | 11 mV/A/m | 9.6 kg |
| 6 mm² | 84/0.30 | 46 A | 41 A | 7.3 mV/A/m | 14 kg |
| 10 mm² | 80/0.40 | 63 A | 57 A | 4.4 mV/A/m | 24 kg |
| 16 mm² | 126/0.40 | 85 A | 76 A | 2.8 mV/A/m | 38 kg |
Voltage drop is where this size is usually decided rather than heat. At 4.4 mV/A/m the 11 V that BS 7671's 5% allows on a 220 V circuit is spent at 11 ÷ (63 × 4.4 ÷ 1000) = 40 m with the cable at its full 63 A. On three loaded conductors at 400 V the budget is 20 V and the distance is 20 ÷ (57 × 4.4 ÷ 1000) = 80 m. Step up to 16 mm² and the same load reaches roughly half as far again, which is often cheaper than moving the board.
These figures assume the cable is clipped direct in open air at 30°C. A flexible cable left wound on its drum under load cannot shed heat and must be run out first. Conduit, bundling and high ambient temperature each take another bite, handled in BS 7671 by correction factors rather than by one invented “real world” number. Work yours out with the cable size calculator and the voltage drop calculator, then have a licensed electrician confirm it.
| Property | Value |
|---|---|
| Conductor | Plain annealed copper, class 5 flexible stranded |
| Nominal area | 10 mm² × 3 cores |
| Strand construction | 80/0.40 mm per core (typical) |
| Max conductor resistance at 20°C | 1.91 Ω/km |
| Current capacity (method C) | 57 A (3 loaded) / 63 A (2 loaded + earth) |
| Voltage drop | 4.4 mV/A/m |
| Voltage rating | 300/500 V |
| Insulation / sheath | PVC / PVC, 70°C conductor rating |
| Conductor copper weight | ≈ 267 kg/km (3 × 88.9 kg/km) |
| Reference standards | IEC 60228 (conductors), IEC 60227 (PVC cables) |
Worked example, using the 4.4 mV/A/m in the table. A pump lead carrying 25 A down a 60 m drop loses 25 × 60 × 4.4 ÷ 1000 = 6.6 V, which is 3% of a 220 V supply and inside the 5% BS 7671 allows on a power circuit. Take the same 25 A to 100 m and the drop is 11 V — exactly that 5%. Below that depth the metres have chosen the size for you, and the next step is 16mm 3 core flexible cable at 2.8 mV/A/m. On a borewell it is nearly always the depth, not the motor, that sets the cable.
Flexible and standard are the same copper and the same 10 mm². The difference is how the area is divided. Class 5 splits it into 80 strands of 0.40 mm; class 2 uses 7 strands of 1.35 mm. Thin strands slide past each other as the cable bends, so the conductor tolerates being coiled and uncoiled; a thick-stranded class 2 core flexed often enough will fatigue and break inside a sheath that still looks perfect.
| Property | Class 5 (flexible) | Class 2 (standard) |
|---|---|---|
| Strands | 80/0.40 | 7/1.35 |
| Max resistance | 1.91 ohm/km | 1.83 ohm/km |
| Current capacity | 57 A / 63 A | 57 A / 63 A |
| Bends repeatedly | Yes | No |
| Typical use | Trailing leads, portable tools | Fixed wiring, trays, conduit |
The class 5 build's slightly higher resistance is permitted by the standard and does not change what the cable carries. Buy flexible when the cable will move. For a run that is clipped up once and forgotten, 10mm 3 core standard cable is the same copper in the cheaper build.
Live, neutral and earth down to a single-phase motor. The earth core in the same sheath is the reason 3 core is the standard choice on a pump.
Welding sets, compressors and mixers on their own lead, where the earth must travel with the supply and the cable is coiled after every shift.
Three phases on the three cores. All three are loaded, so the figure is 57 A rather than 63 A — about 39 kVA at 400 V.
Core count follows the circuit. Two core is line and neutral with a separate earth. Three core is line, neutral and earth — or three phases without a neutral. Four core is three phases plus a neutral. Same 10 mm² conductor throughout; what changes is how many of them are loaded.
| Cores | What runs in it | Loaded | Current capacity |
|---|---|---|---|
| 2 core | Line and neutral, earth run separately | 2 | 63 A |
| 3 core | Line, neutral and earth — or three phases, no neutral | 2 or 3 | 63 A / 57 A |
| 4 core | Three phases plus neutral | 3 | 57 A |
The same size in the other builds: 10mm 2 core flexible cable and 10mm 4 core flexible cable. One step up is 16mm 3 core flexible cable at 76 A on three loaded conductors; one step down, 6mm 3 core flexible cable at 41 A.
Three checks you can run yourself on any seller's cable, ours included. A weighing scale, a tape and a vernier will settle a “full gauge” claim in about ten minutes.
Conductor mass = area × cores × 8.89 kg/km per mm². For 10 mm² 3 core that is 10 × 3 × 8.89 = 267 kg/km, so a 90 m coil holds about 24 kg of copper before insulation and sheath.
A class 5 core at this size is about 80 strands of 0.40 mm. Cut the end square and count. Far fewer, thicker strands means a class 2 conductor being sold as a flexible one.
Get the metre count in writing before you pay, then check it with a measuring wheel. A short coil is the quietest way a per-coil price stops being the price you calculated.
