We will not rate another maker's cable. We have not tested Service Cables, we hold no test reports, and we have found none published for either company.
What we can give you is the check that works at a shop counter with nothing but a scale: copper has a fixed mass per metre for a given size, so a coil cannot weigh less than the copper it is sold as. A 90 m coil of single-core 4 mm² carries 3.20 kg of conductor before any insulation is counted. Weigh ours the same way.
Copper's mass per unit length is fixed by its density and its cross-section, and nothing a factory does changes it. Run the division across the sizes and the same constant falls out every time: 22.2 kg/km ÷ 2.5 mm² = 8.88, 35.6 ÷ 4 = 8.90, 142.2 ÷ 16 = 8.89, 222.3 ÷ 25 = 8.89. So a copper conductor weighs about 8.89 kg per kilometre for every mm² of cross-section, and from that one number every row below is arithmetic.
This is the check that needs no instrument and no standard on your desk — a scale and the coil length. It will not tell you whether the insulation is right or whether the conductor was properly annealed. What it does tell you, in one weighing, is whether the cable in your hands contains the copper you are being charged for, which is the question most buyers are actually asking when they compare two brands on price.
| Size | Copper per km | In a 90 m coil | In 100 m of 3 core |
|---|---|---|---|
| 1.5 mm² | 13.3 kg | 1.20 kg | 3.99 kg |
| 2.5 mm² | 22.2 kg | 2.00 kg | 6.66 kg |
| 4 mm² | 35.6 kg | 3.20 kg | 10.68 kg |
| 6 mm² | 53.3 kg | 4.80 kg | 15.99 kg |
| 10 mm² | 88.9 kg | 8.00 kg | 26.67 kg |
| 16 mm² | 142.2 kg | 12.80 kg | 42.66 kg |
| 25 mm² | 222.3 kg | 20.01 kg | 66.69 kg |
Ask what a coil is, in metres, and get it said out loud before the scale comes out. Coil lengths differ between makers, and a short coil is the quietest way for a weight to come out low without anything being wrong with the copper.
Gross weight on the shop scale, then subtract the drum or the wrapper if there is one. Do the same on both brands you are comparing, at the same size and the same coil length — the comparison is what carries the information.
The coil must weigh more than its copper figure above, because insulation and sheath are on top. If a 90 m coil of single-core 4 mm² reads under 3.20 kg, the conductor is not 4 mm² of copper — ask what it is; for a sheathed multi-core coil, compare against the three-core column instead, which puts 100 m of 4 mm² three-core at 10.68 kg.
It is a floor test, not a precision test. Insulation and sheath weight varies between makers, so a coil that clears the floor comfortably has told you only that the copper is roughly there — it has not told you that the conductor is exactly on size. For that, count the strands and measure one: the arithmetic is on the conductor measurement page. For whether the metal is copper right through rather than copper-clad, the mass difference is large and obvious, and the method is on how to check the conductor is copper.
It also says nothing about insulation class or voltage rating. Fixed-wiring cable here is 450/750 V; light flexible cord is 300/500 V, and the two are not interchangeable however the coil weighs. Read the print on the sheath.
The table above is also the reason we quote live instead of publishing a fixed figure. Most of what you pay for a copper cable is the copper in it — 10.68 kg of it in 100 m of 4 mm² three-core — and copper is priced daily. A published per-metre number is stale within the week, which is why our rate goes out on WhatsApp against your size and your metres rather than sitting on a page.
The rest of it is drawing, extrusion, laying-up and delivery. We draw the copper on our own line in Lahore and sell factory-direct with no dealer margin between the line and your site: standard cable to IEC 60228 class 2, flexible cable to class 5, both PVC at 450/750 V for fixed wiring. Roots in the copper trade since 1992; the cable line itself is newer. Punjab in 1–2 days, the rest of Pakistan in 2–4. The full list of things worth asking any supplier is on how to choose a cable supplier in Pakistan.
Send the size, the core count and the metres. We quote the day's factory rate on WhatsApp and tell you the coil length before you order.
