Specifications

Conductor resistance per IEC 60228 class 2. Current capacity and voltage drop per BS 7671, installation reference method C (clipped direct), 30°C ambient, PVC insulation, taken as the nearest published reference for armoured construction. Voltage rating and armour build are typical for PVC/SWA/PVC cable — confirm the exact construction with Pilone Cables. Derate for grouping and higher ambient temperature. Verify sizing with a licensed electrician for your installation.

Conductor copper weight	≈ 35.6 kg/km
Typical use	Underground feeds for small domestic and small commercial supply runs; outdoor runs needing impact and rodent protection

Current capacity depends on how the cable is installed. Derate for grouping and high ambient temperature. Have a licensed electrician confirm the size for your load and run length — or start with the cable size calculator.

How far a 4 mm² run can go

Voltage drop sets the longest run before lights dim and motors struggle. BS 7671 allows 3% on lighting circuits and 5% on other circuits; on a 230 V single-phase supply that is 6.9 V and 11.5 V. At this cable's 11 mV/A/m, the longest one-way run is:

Longest one-way run for 4 mm² armoured cable, single-phase 230 V, at 11 mV/A/m. Loads shown up to the cable's 36 A capacity. Three-phase circuits allow longer runs.
Load	Lighting circuit (3%)	Other circuits (5%)
16 A	39 m	65 m
20 A	31 m	52 m
25 A	25 m	41 m
32 A	19 m	32 m

Check your own load and length with the voltage drop calculator. Every 100 m of each core holds 3.6 kg of copper; cable is priced from the day's copper rate, which is why each size up costs more.

Next size up or down

Armoured cable sizes either side of 4 mm², same reference conditions as the specification table.
Size	Current capacity, 2 loaded	Voltage drop	Copper per 100 m of core
4 mm² (this cable)	36 A	11 mV/A/m	3.6 kg
6 mm²	46 A	7.3 mV/A/m	5.3 kg

Other armoured sizes

Current capacity with two loaded conductors, BS 7671 reference method C, 30°C ambient. Same class 2 steel wire armoured construction in every size.

Frequently asked

What is the price of 4mm armoured cable in Pakistan?

The price moves with the daily copper rate, so we quote it the day you order. We sell factory-direct from Lahore, with no dealer margin on top. Message us on WhatsApp for today's price per meter.

What is 4mm armoured cable used for?

Underground feeds for small domestic and small commercial supply runs, and outdoor runs where the cable needs protection from impact or rodents. It carries 36 A with two loaded conductors on method C, and 32 A with three loaded conductors.

Can I get 4mm armoured cable delivered?

Yes. We dispatch from Lahore — courier for single coils, transport for bulk. Punjab arrives in 1–2 days, the rest of Pakistan in 2–4 days. See delivery details.
